Our ISBM Machine Benefits
1. The quality is better. The plastic bottles produced by the blow molding machines from Japan all have a parting line. There is a protrusion of plastic in the middle of the two molds on either side, which results in a mark. However, our molds have extremely high precision, and the mark is completely invisible.
2. Our production is fast, with a large number of screw solutions and high speed. While Japan can produce four plastic bottles at a time, we can produce six.
3. Save energy. Our machines consume 15% to 25% less energy than those in Japan, Europe, and the United States.
4. A wide range of electric control technologies has been adopted to replace hydraulic and pneumatic components. For example, the pneumatic components used in the bottom cutting mechanism in Japan are replaced by servo motors here, and the speed of the servo motors is doubled. In the pharmaceutical industry and other fields, fully servo motors can be used without any hydraulic systems, ensuring compliance with GMP standards and operation in an oil-free and pollution-free environment.

Advantages of the Y650-V4 Injection Stretch Blow Molding Machine
1. Energy Efficient
The one step injection stretch blow molding machine retains preform heat directly from the injection stage through to blowing, eliminating secondary reheating. This thermal efficiency reduces energy consumption by up to 40% compared with two-stage reheat ISBM systems. The Y650-V4 servo pump architecture delivers a further 15% to 25% reduction in power draw relative to conventional Japanese, European, or American hydraulic-pump machines running at equivalent output, translating into meaningful savings across 24-hour multi-shift production schedules.
2. Excellent Performance
The longitudinal stretch rod induces biaxial molecular orientation in PET and PETG resins before compressed air expands the preform outward. This dual-axis orientation substantially raises compression resistance, barrier performance against oxygen and carbon dioxide, and optical transparency. These properties are critical for large-format beverage containers, barrier-critical pharmaceutical bottles, and premium cosmetic packaging produced on this PET injection stretch blow molding machine, meeting the highest demands for product integrity and shelf appeal.
3. High Precision and Dimensional Stability
Full-process automation via the Inovance or MiRLE PLC controls every variable from injection speed and mold temperature through stretch rod timing and blow pressure, removing reliance on manual operator adjustment. CMN's precision mold manufacturing tolerances result in parting line marks on finished bottles that are virtually invisible, a clear improvement over the visible parting lines typical on Japanese-origin tooling. This level of dimensional consistency is essential for high-volume, multi-shift mass production environments.
4. High Material Utilisation
Single-stage processing eliminates the runner and sprue waste associated with two-stage systems. Because the preform passes directly from injection to stretch-blow without re-melting, there is no regrind loop to manage and no degraded-material scrap generated at startup or after colour changes. The result is lower raw-material cost per unit, a simpler waste stream, and a reduced environmental footprint. This makes the customized injection stretch blow molding machine a strong fit for factories targeting sustainability certifications or ISO 14001 environmental management goals.
5. Low Operating Cost and Compact Footprint
Integrating injection, stretching, and blowing into one machine at 6,100 x 2,600 x 4,200 mm means floor space requirements are far lower than those of an equivalent two-machine line. Servo-driven motion systems reduce electrical running costs while requiring less hydraulic fluid maintenance. Labour intensity per unit output is also lower because one operator can oversee the complete production cycle, reducing headcount requirements for high-output bottle manufacturing operations and improving overall line efficiency.
6. Compatible with Japanese AOKI and ASB Molds
The Y650-V4 is designed as a direct replacement for AOKI injection stretch blow molding machines and is compatible with ASB-series large-format mold tooling. For factories already operating AOKI 500-series or ASB molds, no new mold investment is required when upgrading the machine. This compatibility is a decisive factor for packaging companies comparing injection stretch blow molding machine manufacturers and seeking a lower total migration cost when switching from a Japanese machine platform to CMN, protecting capital already invested in quality tooling.
ISBM Machine Operating Principle
1. Processo de Injeção
The injection process is the initial stage. Molten PET or PETG resin is injected into the preform mold under high temperature and pressure. Injection speed, injection pressure, and mold temperature are precisely controlled to ensure the molten plastic fills the mold cavity uniformly and completely, producing a preform of the required shape and dimension. The Y650-V4 handles theoretical injection volumes from 340 cm3 to 480 cm3 depending on screw diameter, serving a wide range of preform weights for large-format containers.
2. Processo de alongamento
The preform is indexed to the temperature-conditioning station, where core and barrel temperatures are regulated to the optimal stretch window. The stretch rod elongates the preform longitudinally, inducing molecular chain orientation along the vertical axis. Cooling time and conditioning temperature are controlled carefully to ensure dimensional stability and surface quality before blowing. The Y650-V4 features TEMP regulating core stroke and barrel stroke of 300 mm each, providing precise thermal conditioning for large preforms destined for 5L to 20L containers.
3. Processo de sopro
After stretching, the preform is transferred into the blow mold and compressed air at 2.0 to 3.5 MPa expands the softened plastic outward against the mold wall, forming the predetermined bottle shape. This biaxial orientation step is critical to final bottle wall thickness uniformity, clarity, and structural strength. The Y650-V4 blow mold stroke is 175+175 mm with a blow clamping force of 400 KN single side, enabling accurate shaping of containers up to 20 litres and 280 mm in diameter across up to 4 cavity positions.
4. Molding and Cooling Process
After blowing, the bottle is held in the mold while cooling channels circulate chilled water to rapidly remove heat from the bottle wall. Controlled cooling uniformity, speed, and duration allow the PET or PETG to solidify in its final shape with the required surface finish and dimensional accuracy. Cooling water pressure is maintained at 0.4 to 0.6 MPa and oil cooler water temperature is held between 20 and 25C to stabilise mold temperature across long production runs. The finished bottle is then ejected at the take-out station with a 300 mm take-out stroke.
Áreas de aplicação
1. Pharmaceutical Bottle
Large-format pharmaceutical containers and oral liquid bottles in PET or PETG benefit from the Y650-V4's precise neck geometry, clean parting lines, and optional servo-only drive system that meets GMP oil-free and contamination-free production standards. The machine's dimensional accuracy and recipe-based PLC control support pharmaceutical batch traceability requirements and consistent quality across production runs.
2. Cosmetic Bottle
High-end skincare, perfume, and toner bottles demand optical clarity and surface smoothness that the ISBM process delivers through biaxial molecular orientation of PETG. The Y650-V4 handles specialty and non-standard shaped cosmetic containers. CMN has supplied machines to manufacturers serving major cosmetic brands, and the invisible parting line finish is a key differentiator for premium shelf presentation in retail and duty-free markets.
3. Chemical Bottle
Industrial chemical containers, lubricants, and agrochemical packaging require strong barrier properties and wide-mouth neck designs. The Y650-V4's 280 mm maximum bottle diameter and 140 mm neck diameter capacity make it suited for wide-mouth chemical and industrial product packaging in PET. The blow clamping force of 400 KN ensures mold integrity even when producing heavy-wall chemical containers at full production pressure.
4. Shampoo Bottle
Personal care shampoo and conditioner containers frequently feature complex shoulder geometry and ergonomic grip shapes. The one step process ensures consistent wall thickness in curved zones that are difficult to achieve with extrusion blow molding, resulting in professional-grade containers. The Y650-V4's precision temperature conditioning controls the preform heat profile across the bottle shoulder area for uniform material distribution in asymmetric designs.
5. Beverage Bottle
Large-volume water dispensers and beverage containers from 5L to 20L are the Y650-V4's flagship application. PET biaxial orientation produces the hoop strength and clarity expected in this segment. Single-cavity 20L barrel bottles with 280 mm body diameter and 140 mm neck diameter are within the machine's rated product dimensions, and the energy savings versus Japanese machines make this one step ISBM machine highly competitive for volume water barrel producers worldwide.
6. Feeding Bottle
Infant feeding bottle production places the highest demands on material clarity, food contact compliance, and neck thread precision. The ISBM process and servo-controlled mold clamping deliver the geometric accuracy needed for leak-free nipple threading while supporting BPA-free PETG resin processing for infant safety compliance. The Y650-V4 is suitable for specialised feeding bottle mold designs requiring non-standard neck profiles.
7. Body Wash Bottle
Large pump-dispenser body wash bottles in the 500 ml to 2,000 ml range are frequently produced using the ISBM process. The Y650-V4 supports multi-cavity configurations down to 180 mm bottle diameter at 4 cavities per cycle, enabling efficient body wash bottle production with excellent surface gloss and consistent wall distribution. Servo-controlled mold clamping ensures precise parting line registration across all cavities for every cycle.
8. Bulb Cover
Transparent lighting diffuser covers and bulb housings require high optical clarity and dimensional repeatability. PET and PETG blown by the ISBM process achieve the light-transmission properties required for LED and fluorescent bulb covers. The Y650-V4's large upper mold stroke of 1,070 mm accommodates elongated bulb cover shapes that shorter-stroke machines cannot form, making it the preferred choice for specialty elongated industrial lighting cover production.

Injection Stretch Blow Molding Machine Components
Clamping Unit
The injection clamping unit delivers 400 KN of force to hold the preform mold closed during high-pressure injection. The blow clamping unit provides a matching 400 KN single side to seal the blow mold against 2.0 to 3.5 MPa blowing air. Both units use a high-pressure compensation function to maintain consistent closure force as mold components expand from thermal cycling, ensuring dimensional repeatability across long production runs without operator intervention.
Injection Unit
Controlled by a single cylinder, the injection unit features a plasticising screw available in 50, 55, or 60 mm diameter with theoretical injection capacity reaching 480 cm3 at 60 mm. The melt motor can be controlled hydraulically or by a servo motor depending on the configuration selected. A nano far-infrared energy-saving heating ring rated at 15 KW provides efficient, uniform barrel heating with lower energy waste than conventional resistance heaters.
Preform and Blow Mold
CMN manufactures preform injection molds and blow molds to extremely tight tolerances, resulting in parting lines on finished bottles that are virtually invisible, a marked improvement over standard Japanese machine tooling. The Y650-V4 accepts 1 to 4 cavity blow mold configurations. Upper mold stroke is 1,070 mm and lower mold stroke is 550 mm, enabling bottles up to 510 mm in height and compatible with existing AOKI and ASB large-format mold tooling.
Blow Pin and Stretch Rod
The blow core enters the preform neck and delivers compressed air at 2.0 to 3.5 MPa to expand the preform radially. Working in tandem with the stretch rod, which extends longitudinally to stretch the preform before air inflation, the two-stage action creates biaxial orientation in the bottle wall. Blow core stroke on the Y650-V4 is 300 mm, accommodating tall container formats including large water dispensers and elongated industrial containers.
Cooling System
Chilled water at 0.4 to 0.6 MPa circulates through channels in the blow mold to rapidly solidify the bottle wall after expansion. A separate machine oil cooler circuit maintains hydraulic oil temperature within 20 to 25C at 0.3 to 0.4 MPa, protecting the 600 L oil tank and extending hydraulic component service life. Controlled mold temperature is essential for consistent bottle shrinkage and dimension repeatability, particularly for large-format containers with thick wall sections.
Ejection System
After cooling, the turntable indexes to the take-out station where finished bottles are removed by the take-out mechanism with a 300 mm stroke. The turntable is driven by a Japan Yaskawa or WEICHI servo motor through a Taiwan TSUNTIEN reducer, providing smooth, precise indexing between all four stations. The Airtak air cylinder actuates the take-out arm for reliable, high-speed bottle discharge without surface marking or deformation on the finished container.
Hydraulic System
Three servo pump systems drive the main hydraulic circuit, reducing energy waste during idle phases by matching pump output to actual demand. YUKEN Taiwan hydraulic pressure control valves regulate circuit pressure, while oil tubes of Italian imported material ensure long-term leak resistance. The 600 L oil tank provides ample thermal mass for stable hydraulic fluid temperature management during extended high-output production runs, minimising maintenance intervals.
IBM Machine vs ISBM Machine: Key Differences
Understanding the difference between an máquina de moldagem por injeção e sopro (IBM machine) and an injection stretch blow molding machine (ISBM machine) is essential when selecting blow molding equipment. The forming method determines bottle wall structure, neck accuracy, surface finish, and the range of materials and sizes that can be produced efficiently.
IBM: Injection Blow Molding
The IBM machine process starts with an injection-moulded preform that already carries a precise neck and thread geometry. The preform is transferred directly into a blow mold and inflated into the final shape without any stretch rod involvement. IBM is preferred when sealing accuracy is the primary requirement and container size is small, such as for pharmaceutical dropper bottles, cosmetic jars, and precision-threaded caps. IBM produces excellent neck definition but does not achieve the biaxial molecular orientation that gives ISBM bottles their superior strength-to-weight ratio and barrier performance.
ISBM: Injection Stretch Blow Molding
The injection stretch blow molding machine also begins with a preform, but inserts a mechanical stretch rod before the blow phase. The rod elongates the preform longitudinally while compressed air expands it radially, creating biaxial orientation that dramatically improves compression resistance, barrier performance, optical clarity, and lightweight potential. ISBM is the dominant process for PET beverage bottles, large water containers, and any application where wall strength and visual clarity are critical. The Y650-V4 is the flagship product of CMN Transmission as an ISBM machine manufacturer for large-format containers.
Where Each Machine Type Fits Best
| Tipo | Starting Form | Common Materials | Best Products | Main Strength | Main Limitation |
|---|---|---|---|---|---|
| EBM | Parison | HDPE, LDPE, PP, PVC | Large containers, handled bottles, drums | Flexible sizes, lower tooling cost | Less neck precision, possible flash |
| IBM | Preform | HDPE, PP, PET, PS | Small precision bottles and jars | Accurate neck finish and thread definition | Higher tooling cost, smaller size range |
| ISBM | Stretched preform | PET, PETG, PP | Clear bottles and large-format containers | Strength, clarity, lightweighting | Higher machine and mold cost |
| PET Blow Machine | Preform-based | PET, rPET | Water, soda, oil, cosmetic bottles | Scalable PET bottle production | Not a separate process category |
How the Forming Method Changes Bottle Quality
The forming method determines far more than how plastic enters the mold. It directly affects wall thickness distribution, neck accuracy, surface finish, clarity, mechanical strength, and defect risk. A machine may have sufficient output capacity, but if the forming method does not match the bottle design, problems such as leakage, thin wall zones, poor transparency, or unstable bottle weight will emerge during sustained production runs.
IBM Forms from a Preform Without Stretching
IBM injects a precise preform with a fully formed neck, then transfers it directly to a blow mold without stretching. The absence of a stretch rod means no biaxial orientation is induced, resulting in lower wall strength and clarity than ISBM. IBM excels for small pharmaceutical and cosmetic bottles where tight neck tolerances outweigh the need for orientation-enhanced wall performance and the container size is below 500 ml.
ISBM Adds the Stretch Rod Advantage
The stretch rod in the Y650-V4 aligns polymer chains axially before radial inflation orients them circumferentially. This biaxial orientation produces bottles with superior top-load strength, drop resistance, and gas-barrier performance at lower wall thickness, making each bottle lighter without sacrificing durability. For 5L to 20L water containers, this weight reduction translates to significant material cost savings at high production volumes.
Compatible Raw Materials for the ISBM Machine
PET
Polyethylene terephthalate is the primary resin for the Y650-V4. Excellent clarity, gas barrier properties, and recyclability make it ideal for large beverage containers, water dispensers, and food-grade packaging. PET responds well to ISBM biaxial orientation, achieving high strength at low wall thickness and producing the crystal-clear appearance consumers expect in large-format water bottles and premium food containers.
PETG
Glycol-modified PET offers superior impact resistance and optical clarity versus standard PET, with easier processing and better chemical resistance. PETG is preferred for cosmetic bottles, premium beverage containers, and infant feeding bottles where BPA-free compliance is required and superior gloss is demanded by brand owners and end consumers in regulated markets.
PP
Polypropylene is valued for chemical resistance, high-temperature tolerance, and food contact safety. PP containers produced on ISBM machines are used for hot-fill food packaging, pharmaceutical preparations, and containers requiring autoclave sterilisation. PP requires slightly higher processing temperatures than PET and benefits from carefully tuned stretch rod timing and conditioning zone temperature management.
PPSU
Polyphenylsulfone withstands repeated steam sterilisation and autoclave cycles without degradation, making it the preferred material for medical-grade infant bottles and reusable pharmaceutical containers. PPSU is fully BPA-free and maintains clarity after hundreds of sterilisation cycles, meeting the requirements of the most demanding healthcare and infant safety standards globally.
PC
Polycarbonate provides exceptional impact strength and optical clarity for demanding industrial and laboratory containers. PC is used in reusable large-volume water dispensers and precision laboratory bottles. Temperature and UV resistance make PC suitable for applications where long service life under repeated handling and exposure to varying environmental conditions is required.
Tritan
Eastman Tritan copolyester delivers PC-like clarity and toughness without bisphenol content, making it the premium choice for high-end reusable beverage bottles, infant feeding products, and kitchen containers. Tritan is dishwasher-safe and maintains structural integrity and gloss through thousands of washing cycles, supporting premium brand positioning in health-conscious consumer markets.
PCTG
PCT glycol copolymer balances excellent chemical resistance with clarity and toughness at a lower material cost than Tritan or PC. PCTG is widely used for cosmetic packaging, laboratory containers, and food-contact bottles where chemical exposure and frequent sterilisation are concerns but engineering-grade material cost must be managed to maintain competitive product pricing.
PLA
Polylactic acid is a bio-derived, industrially compostable resin gaining adoption in sustainable packaging. PLA produces clear containers with good rigidity for short-shelf-life beverage and food products where biodegradability or bio-based content certification is a brand requirement. PLA processing requires careful temperature management to avoid hydrolytic degradation during the injection stage.

ISBM Machine for Pharmaceutical Bottle: Full Production Process
STEP 1: Machine Preparation
Select pharmaceutical-grade PET or PETG resin and verify drying status before loading. PET must be dried to below 0.02% moisture in a dehumidifying desiccant dryer at 160 to 180C for 4 to 6 hours to prevent hydrolytic degradation during injection. Preheat the Y650-V4 barrel zones to the appropriate processing temperature for your resin grade. Verify mold clamping force settings, cooling water supply pressure, and compressed air line pressure before initiating the production sequence to ensure all utilities are within specification.
STEP 2: Parameter Setting
Load the saved recipe for your pharmaceutical container from the Inovance or MiRLE PLC. Set injection pressure, injection speed, screw rotational speed within the 150 to 220 RPM range for 60 mm screw, stretch rod timing, blowing pressure between 2.0 and 3.5 MPa, and cooling duration. For GMP pharmaceutical applications, adjust parameters to ensure contact surfaces meet cleanliness and contamination-free standards. Document all parameter settings for batch traceability records required by pharmaceutical regulatory frameworks.
STEP 3: Manufacturing Operation
Injection: Molten pharmaceutical-grade resin fills the preform mold at controlled speed and pressure to form a precise preform. Stretching: The preform is conditioned to the optimal stretch temperature and the stretch rod elongates it longitudinally. Blowing: High-pressure air at 2.0 to 3.5 MPa expands the preform against the blow mold cavity to form the finished pharmaceutical bottle. Molding: Cooling water rapidly solidifies the bottle to its final precise shape. The turntable indexes and the finished container is ejected at the take-out station, ready for pharmaceutical filling line transfer.
STEP 4: Quality Inspection
Check finished pharmaceutical bottles for bottle height, body diameter, neck diameter, and wall thickness against your product specification using calibrated gauges. Perform leak tests on neck threads using capped samples under air pressure. Verify optical clarity against reference samples. Review PLC data logs for any parameter drift during the production run. Adjust injection hold pressure, cooling time, or conditioning temperature as needed to maintain dimensions within tolerance. Document all inspection results for pharmaceutical batch records and regulatory submission requirements.
Falhas comuns e resolução de problemas
1. Espessura irregular da parede
Uneven wall distribution is most commonly caused by inconsistent preform temperature, misalignment of the stretch rod relative to the preform centreline, or incorrect blowing pressure timing. Check that temperature conditioning zones are uniform across all cavities, verify stretch rod concentricity, and review the blowing pressure ramp profile in the PLC. Inspect TEMP regulating core and barrel temperatures for inter-cavity variation on the Y650-V4 before adjusting other parameters.
2. White Stress Marks on Bottle Body
White or hazy stress marks in the bottle shoulder or body zone indicate that the preform was too cold when stretching began, causing stress whitening rather than true molecular orientation. Increase the temperature conditioning duration or raise the barrel temperature setpoint. Check that preform residence time in the conditioning station is consistent across cycles, and verify that conditioning zone temperatures match your resin's optimal stretch window for the specific preform weight being processed.
3. Bottle Sticking in Blow Mold
Bottles that adhere to the blow mold surface after expansion indicate insufficient cooling time, elevated mold temperature, or a mold surface finish issue. Verify that cooling water flow rate and temperature (target 20 to 25C for oil cooler, 0.4 to 0.6 MPa for bottle cooling) are within specification. Extend the cooling dwell time. If the problem persists, inspect mold venting channels and consider mold surface polishing or texture treatment to reduce adhesion tendency on large-diameter container walls.
4. Inconsistent Bottle Weight Between Cavities
Weight variation between cavity positions points to uneven melt distribution in the hot runner manifold, differences in cavity filling speed, or individual cavity mold temperature variation. Check hot runner zone temperature setpoints against actual readings, inspect gate tip condition for partial blockage, and measure cooling water flow to each cavity independently. PLC-logged injection pressure curves for each cavity help identify whether a specific cavity position is under-filling consistently.
5. Preform Surface Defects (Splay, Bubbles, Burns)
Surface defects on the preform such as splay streaks, air bubbles, or burn marks at the gate typically result from moisture in the resin, excessive barrel temperature, or trapped air in the melt. PET and PETG are hygroscopic and must be dried to less than 0.02% moisture before processing. Verify drying temperature and duration. Reduce barrel set temperatures in the affected zone and check screw back-pressure. Inspect the non-return valve at the screw tip for wear that may allow melt backflow.
6. Neck Dimension Out of Tolerance
Neck thread or sealing surface dimensions outside tolerance cause cap sealing failures and leakage in the field. Neck geometry is determined at the injection station. Causes include mold core wear, incorrect injection pressure or hold pressure, mold core temperature variation, or resin lot changes. Measure neck dimensions with a neck thread gauge, review injection hold time and pressure curves in the PLC data log, and inspect the neck core and cavity for wear or contamination that may have developed during the current production run.

Perguntas frequentes
Q: What is the maximum bottle volume the Y650-V4 one step injection stretch blow molding machine can produce?
A: The Y650-V4 can produce bottles up to 20 litres in a single-cavity configuration with a bottle diameter of 280 mm and bottle height of 510 mm. In a 2-cavity configuration, maximum volume is also 20 litres at 235 mm or 280 mm diameter. For 3-cavity and 4-cavity configurations, maximum volume is 12 litres and 5 to 7 litres respectively. These are the rated limits for PET and PETG resins at standard wall thickness. Heavier wall specifications reduce the maximum volume achievable per cavity position.
Q: Is the Y650-V4 compatible with Japanese ASB or AOKI ISBM molds?
A: Yes. The Y650-V4 is designed as a direct replacement for Japanese AOKI 500-series machines and is compatible with AOKI 500 and ASB-series large-format mold tooling. This mold compatibility is a major advantage for factories migrating from Japanese machines that want to protect their existing tooling investment. CMN can review your existing mold drawings to verify compatibility before order placement. If your molds require minor interface modifications, CMN's engineering team can advise on the scope of any required changes at no additional consultation cost.
Q: What is the difference between a single-stage and two-stage injection stretch blow molding machine?
A: A single-stage ISBM machine like the Y650-V4 completes injection, conditioning, stretching, and blowing in one integrated machine without transferring preforms off the machine between stages. A two-stage process uses a separate injection moulding machine to produce preforms, cools and stores them, then reheats them in a stretch-blow machine. Single-stage processing avoids secondary reheating energy cost saving up to 40%, reduces contamination risk during preform transfer, and requires less factory floor space. For large bottles, single-stage ISBM is typically preferred over two-stage reheat systems.
Q: What resins other than PET can the Y650-V4 process?
A: The Y650-V4 is rated for PET and PETG as standard materials. CMN can configure the machine for PP, PC, Tritan, PCTG, PPSU, and PLA depending on the application and bottle specification. Resin selection affects screw and barrel design, temperature profile settings, and drying requirements. Specify your target resin when requesting a quotation so CMN can confirm the appropriate screw diameter, barrel heat profile, and any additional tooling required for your target material and container design.
Q: How does the Y650-V4 compare to Japanese injection stretch blow molding machines in energy consumption?
A: The Y650-V4 consumes 15% to 25% less electricity than comparable Japanese, European, and American machines in the same production class. The three-servo-pump hydraulic system matches pump output to actual cycle demand rather than running at constant pressure like conventional fixed-displacement pumps. The nano far-infrared screw heating ring at 15 KW also operates more efficiently than conventional resistance heaters. At a total machine power of 90.7 KW for a 28-tonne machine capable of 20L bottles, the power-to-output ratio is competitive with the best machines globally in this container size class.
Q: Can the Y650-V4 be configured as a fully electric ISBM machine for GMP pharmaceutical use?
A: CMN offers the Y650 platform in Standard, Servo, and Fully Electric configurations. The standard Y650-V4 uses three servo pump systems with a hydraulic circuit. For GMP pharmaceutical applications requiring oil-free operation and avoidance of hydraulic contamination risk, CMN can configure the melt motor and blow molding structure with servo motors replacing hydraulic actuators, significantly reducing contamination risk. Specify your GMP requirements at the time of enquiry and CMN's engineering team will advise on the optimal configuration for your regulatory environment.
Q: What is the typical lead time for the Y650-V4 and does it include mold design?
A: Machine lead time for the Y650-V4 is typically 90 to 120 days from order confirmation and deposit payment, depending on current production schedule and whether custom mold work is included. CMN designs and manufactures both preform injection molds and blow molds in-house. Mold design requires receipt of your bottle design drawings and typically adds 15 to 30 days, which can overlap with machine build time. Total project lead time from initial bottle design review to machine with molds ready for shipment is typically 110 to 150 days for a standard configuration.
Q: How does the Y650-V4 achieve better parting line quality than Japanese ISBM machines?
A: CMN manufactures its blow molds with tighter split-line machining tolerances than industry standard. The two blow mold halves are ground and matched to minimise the step at the parting line. The Y650-V4's blow mold clamping force of 400 KN single side and high-pressure compensation function ensure the two mold halves remain in tight contact under full blowing air pressure of up to 3.5 MPa, preventing the slight mold separation under load that causes visible parting marks on large containers produced at high blowing pressure.
Q: What after-sales support does CMN Transmission provide globally?
A: CMN provides comprehensive after-sales support including installation and commissioning assistance via on-site engineer or remote video support, operator training, spare parts supply from Guangdong stock, remote diagnostic support via video call and PLC data review, and on-site engineer visits for complex technical issues. Spare parts for the Y650-V4 including screws, barrels, heating rings, servo drives, and PLC modules are stocked at CMN's facility and can typically be shipped within 24 to 48 hours of order to minimise production downtime for customers worldwide.
Q: What site utilities does the Y650-V4 require for installation?
A: The Y650-V4 requires a three-phase power supply at 370 to 400 V with a total connected load of 90.7 KW. Cooling water at 0.4 to 0.6 MPa is required for mold and machine body cooling, and a separate oil cooler circuit at 0.3 to 0.4 MPa maintaining 20 to 25C. Blowing compressed air at 2.0 to 3.5 MPa must be supplied by a high-pressure compressor separate from standard workshop air. The machine footprint is 6,100 x 2,600 mm with a height of 4,200 mm. A floor load capacity adequate for the 28-tonne machine weight must be verified with your structural engineer before installation planning.
Avaliações de clientes
Carlos Mendoza, Food Packaging Industry, Mexico
"Our factory in Mexico City produces wide-mouth PET containers for the food processing industry and we ordered the Y650-V4 to handle 5L to 20L large-format containers. The logistics from Guangdong to Veracruz took longer than expected but CMN had all the export documentation in good order so customs clearance was smooth. The machine arrived well-crated with no damage. Installation was done with remote support from CMN via video and our maintenance team managed it well. We are now 5 months in and running 2 shifts daily with good results on bottle weight consistency."
Piotr Kowalski, Contract Packaging, Poland
"We are a contract packaging company in Lodz producing bottles for several FMCG clients. We chose the Y650-V4 specifically for a 10L PETG bottle contract requiring high clarity and specific neck dimensions. CMN reviewed our bottle spec before confirming the machine was suitable. The 60 mm screw option at 480 cm3 theoretical injection volume was what we needed for this heavy preform. Machine has been in production for 7 months, clarity is excellent and our client has reordered. Happy with the overall experience and would not hesitate to recommend CMN to other packaging manufacturers."
Emmanuel Okonkwo, Beverage Packaging, Nigeria
"I was hesitant about purchasing a Chinese ISBM machine but the price difference versus Japanese machines was too significant to ignore given our budget. We visited CMN's factory in Qingyuan in person before committing, the facility was genuinely impressive and the engineering team answered all our technical questions clearly. The Y650-V4 we purchased for 18.9L water barrel production has been running for 10 months in Lagos and we have been very satisfied. Power consumption is definitely lower than our old machine and support response when we have questions has been fast through WhatsApp communication."
Fernanda Costa, Specialty Packaging, Brazil
"We use the Y650-V4 for craft bottle production, producing specialty shaped PET containers for a niche gift packaging client in Sao Paulo. The machine handles our irregular bottle geometry well and the 1,070 mm upper mold stroke was essential for our taller bottle designs. CMN customized the mold cavity layout to our bottle specs, something many suppliers were not willing to do for a smaller order quantity. Lead time from mold approval to machine delivery was 110 days. Our customers appreciate the clarity and invisible parting lines which was a problem with our previous supplier's tooling."
Mohamed Hassan, Edible Oil Packaging, Egypt
"Our company in Cairo supplies PET bottles to edible oil and condiment brands across Egypt and North Africa. We evaluated several one step ISBM machine suppliers and CMN offered the best combination of technical specification and after-sale support commitment. The Y650-V4 is now our main production machine for 5L oil containers. Cycle time is consistent, the servo pump system is quieter than our old hydraulic machine which operators appreciate, and spare parts availability has not been an issue. We already plan to order a second Y650-V4 for our expanded production line next year."
Abdullah Al-Rashid, Beverage Packaging Industry, Saudi Arabia
"We switched from a Japanese AOKI 500 to the Y650-V4 about 14 months ago at our water dispenser factory in Jeddah. Honestly the main concern was whether the molds would work and they fit perfectly, no modification needed. The machine itself runs about 22% less power according to our energy monitoring system, which is significant over 24-hour shifts. Output quality on our 18.9L PET water barrels is excellent and our reject rate is well below what we were getting before. Setup and commissioning took about 5 days with the CMN engineers on site and they were very professional throughout."
Nguyen Thi Lan, Cosmetic Packaging Manufacturing, Vietnam
"We produce large PETG cosmetic bottles for export brands and have been running the Y650-V4 for about 8 months at our facility outside Ho Chi Minh City. The parting line quality is honestly better than what we were getting from our old Japanese machine, our buyers have noticed and complimented the surface finish. CMN were very helpful during the mold design stage, the engineers reviewed our bottle drawings and suggested preform wall adjustments that improved clarity. Delivery was within the quoted lead time and the documentation for customs was complete and accurate."
Priya Mehta, Pharmaceutical Packaging, India
"I run a pharmaceutical packaging operation in Pune and needed a machine that could handle PET bottles from 5L to 12L without oil contamination risk. CMN configured the Y650-V4 with the servo melt motor option which largely avoids the contamination concern for our GMP environment. Been running for about 6 months, output consistency is good, the PLC stores all our parameter recipes which makes changeover between bottle sizes much faster than our previous setup. After-sales response when we had an early sensor issue was quick, they had a solution within 24 hours by video call."
Ahmet Yilmaz, Machinery Trading and Distribution, Turkey
"We import machines for bottle production clients across Turkey and evaluated four manufacturers before selecting CMN for this order. The Y650-V4 specification for large bottles was the best we found at this price point, about 30% less than comparable Japanese machines. What impressed us most was that CMN was transparent about lead time and did not move the delivery date on us. One of our clients who bought through us is now on month 11 with zero unplanned downtime, which is a very good result for a first machine from a new manufacturer relationship."
