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.

Core Advantages of the Y250-V4 One Step ISBM Machine
1. Energy Efficient
This one step injection stretch blow molding machine directly retains the residual heat of the preform from the injection stage through to the blowing stage, eliminating the need for secondary reheating. This fundamental design difference reduces total energy consumption by approximately 40% compared to two-step blow molding processes. Over a full production year, the savings in electricity costs are substantial, making the Y250-V4 one of the most cost-efficient ISBM machine options for high-volume manufacturers.
2. Excellent Performance
The biaxial stretching stage causes plastic molecules to align in an oriented manner, dramatically improving compression resistance, barrier properties, and transparency of the finished container. This is particularly valuable for pharmaceutical packaging, carbonated beverages, and cosmetic bottles where clarity and structural integrity are non-negotiable. The Y250-V4 consistently outperforms conventional injection blow molding machines in finished bottle quality metrics.
3. High Precision and Dimensional Stability
Full-process automation control through the Inovance / MiRLE PLC system minimizes human error at every stage, from injection through cooling and ejection. This makes the Y250-V4 ideal for large-scale, continuous production where uniformity across thousands of cycles per shift is required. Dimensional tolerances are held tightly, ensuring consistent fill volumes, reliable cap sealing, and reduced downstream rejection rates across all supported bottle sizes.
4. High Material Utilization
The single-stage process nature of this single-stage injection stretch blow molding machine means the preform is injection-molded precisely and then blown to final shape with minimal excess material. There is no flash, no trimming waste, and no significant scrap stream compared to extrusion-based processes. This translates directly to lower raw material costs per unit produced and a smaller environmental footprint, supporting your sustainability targets while keeping operational costs competitive.
5. Lower Total Operating Cost
With a compact footprint of 6.3 m x 2.4 m x 3.7 m and a weight of 16 tonnes, the Y250-V4 occupies less floor space than comparable multi-machine setups. Labor requirements are reduced through full automation. Energy consumption is 15% to 25% lower than Japanese, European, and American equivalent machines. Combined with low maintenance cycles and high product stability, the total cost of ownership over a five-year horizon is significantly lower than alternative IBM machines in this performance class.
6. Compatible with Japanese ASB Molds
The Y250-V4 is fully compatible with the Japanese ASB-70DPH model molds. This makes it an ideal replacement for ASB ISBM machines in existing production lines. Facilities can transition to the Y250-V4 without scrapping their current mold inventory, protecting capital investment and enabling a fast, cost-effective upgrade to a more efficient platform.
Injection Stretch Blow Molding Machine Process Flow
Step 1: Injection Molding
The process begins by heating plastic resin (commonly PET or PC) to a molten state. The molten resin is injected into a mold cavity to form a preform, which is partially cooled to stabilize its shape while retaining enough heat to allow stretching in the next stage. During this phase, the preform neck finish is preserved in its final form. This design ensures reliable sealing, dimensional accuracy, and proper thermal conditioning for the subsequent stages.
Step 2: Preform Conditioning and Transfer
A specialized rotary transfer system moves the freshly molded preform from the injection station to the conditioning zone. Along the way, it passes through controlled heating areas that stabilize the preform internal temperature profile. This consistent thermal conditioning supports uniform material behavior during the stretch and blow stages, improving container quality and reducing the risk of defects such as uneven wall thickness or haze.
Step 3: Stretch Blow Molding
This is the stage where the preform transforms into its final container shape. Biaxial stretching begins as a stretch rod extends the preform lengthwise, followed by compressed air (2.0 - 3.5 MPa) inflating it outward to match the mold. By aligning plastic molecules in two directions, the material gains better resistance to gas penetration and impact, which is especially important for carbonated beverages, pharmaceutical liquids, and pressurized containers. Consistent wall thickness and stable dimensions are achieved in every cycle.
Step 4: Cooling and Ejection
Once the bottle has been fully blown to its final shape, the container is rapidly cooled inside the mold to solidify its form. The integrated cooling water system operates at 0.4 to 0.6 MPa and maintains the mold temperature within the optimal range. After sufficient cooling, the mold opens and automatically ejects the finished bottle. The take-out stroke of 190 mm ensures smooth, damage-free removal. This step completes the molding cycle, delivering a ready-to-use plastic container at full production speed.

ISBM Machine vs. EBM Machine: Which Is Right for You
Process Overview
ISBM (Injection Stretch Blow Molding) is a process where plastic is first injection-molded into a preform, which is then stretched within a blow mold to form the final container. This method is widely used for producing high-quality PET bottles, especially for beverages, cosmetics, and pharmaceuticals. The Y250-V4 is a leading example of a high-performance PET injection stretch blow molding machine that maximizes all the advantages of this process.
EBM (Extrusion Blow Molding) involves extruding a molten plastic tube (parison), which is then captured by a mold and inflated to form the desired shape. EBM is widely used for manufacturing containers with handles, complex shapes, and larger sizes, such as detergent bottles and automotive parts. While EBM machines offer design flexibility, they lack the clarity, dimensional precision, and energy efficiency of modern ISBM machines.
Cost Comparison: ISBM vs EBM
Initial Investment
ISBM: The ISBM process requires high-precision injection and blow molding machines, which generally translates to a higher initial investment. Molds are complex and costly due to the need for both preform and blow mold components. However, the higher unit output speed and lower per-unit energy cost recover this investment rapidly in volume production.
Initial Investment
EBM: EBM machines are typically less expensive upfront. Mold designs are simpler, especially for basic shapes, making EBM a more accessible option for startups and small-scale operations that do not require the optical clarity or tight tolerances of ISBM-produced containers.
Operating Costs
ISBM: ISBM machines such as the Y250-V4 are energy-efficient, particularly when producing lightweight bottles in high volumes. Three servo pump systems and nano far-infrared heating reduce energy draw significantly. Skilled operators are required, but the fully automated PLC control system reduces daily labor involvement substantially.
Operating Costs
EBM: EBM processes can be more energy-intensive, especially for thicker-walled or larger containers. Material waste is higher due to flash and trimming, which increases raw material consumption and disposal costs. For thin-walled, high-clarity containers, EBM is generally less competitive than ISBM on a per-unit cost basis.
Performance Comparison: ISBM vs EBM
Product Quality and Consistency (ISBM)
ISBM produces containers with superior optical clarity, structural strength, and dimensional accuracy. Ideal for applications requiring tight tolerances and high aesthetic standards, such as beverage bottles, cosmetic containers, and pharmaceutical packaging where consumer confidence is directly tied to container appearance.
Product Quality and Consistency (EBM)
EBM offers flexibility in design, making it suitable for containers with handles or unique shapes. However, wall thickness may vary, and surface finish is generally less refined compared to ISBM. It is well-suited for opaque or colored containers where clarity is not a primary requirement.
Container Design Capabilities (ISBM)
ISBM excels at producing lightweight, uniform, and crystal-clear containers. The process is best for designs that can be formed from a preform, including round, oval, and most standard bottle geometries. Custom preform tooling and mold cavities enable customized injection stretch blow molding machine configurations to meet specific market requirements.
Container Design Capabilities (EBM)
EBM excels at producing containers with handles, complex geometries, and larger volumes. It offers more design freedom for unique applications such as automotive fluid tanks, industrial chemical containers, and household product bottles with integrated grips, making it complementary rather than competitive with ISBM in most product portfolios.

Maintenance Tips for the Y250-V4 ISBM Machine
Nettoyage régulier
Clean the injection molds, blow molds, and all mechanical parts thoroughly after each production run to remove plastic residue, dust, and oil accumulation. Pay particular attention to the runner system, cavity surfaces, and blow pin orifices. Clean molds produce visibly better surface finish on finished containers and prevent gradual buildup that can cause dimensional drift over time.
Entretien de la lubrification
Apply appropriate lubricating oils and greases to all guide rails, lead screws, bearing housings, and rotary turntable pivot points according to the maintenance schedule. The Japan NSK lead screws require regular lubrication to maintain precision and prevent premature wear. Inadequate lubrication is one of the leading causes of increased machine friction, dimensional drift, and shortened component service life on high-cycle ISBM machines.
All-Electric System Checking
Inspect all servo drive units, motor connections, encoder feedback cables, and PLC signal wiring at scheduled intervals to verify stable operation. Check servo parameter settings against baseline values recorded at installation. Unstable servo responses, unusual vibrations, or error codes on the Inovance / WEICHI servo drives should be investigated and resolved promptly to prevent machine damage and product quality issues.
Electrical System Maintenance
Inspect the interior of all electrical cabinets and junction boxes periodically to check for signs of overheating, loose connections, or moisture ingress that could lead to short circuits. Verify that all earth bonding is intact, fuses are rated correctly, and contactor contacts are not worn. The nano far-infrared heating ring circuits should be checked for resistance to detect early-stage wire degradation before it affects heating performance.
Mold Maintenance
Inspect the injection molds and blow molds regularly for signs of surface wear, corrosion pitting, or parting surface damage. Any visible wear on cavity surfaces should be addressed immediately, as even minor surface degradation translates to visible finish defects on produced bottles. Replace worn neck ring inserts and blow mold vent plugs on schedule to maintain dimensional accuracy and proper gas venting during the blow cycle.
Machine Parameter Adjustment
Review and fine-tune all machine parameters, including injection pressure, screw speed, heating zone temperatures, blow air pressure, clamping force, and cooling time, after any material changeover, mold change, or extended machine stoppage. Seasonal ambient temperature changes can affect material flow behavior and may require minor parameter recalibration. Document all adjustments in the machine logbook for traceability and continuous process improvement.
How to Choose the Right ISBM Machine for Your Application
1. Define Your Production Volume
Estimate your required daily or monthly output in units. Higher production volumes justify a higher cavity count configuration on the Y250-V4 (up to 14 cavities), while smaller runs may be more efficient with a 2 to 4 cavity setup. The Y250-V4 4-station platform is well-suited to mid-to-large volume production operations, and the cavity configuration can be upgraded as your business scales.
2. Identify Your Bottle Size Range
Match your required bottle dimensions to the machine specifications. The Y250-V4 handles bottle diameters from 30 mm to 200 mm, heights from 100 mm to 220 mm, and volumes from 30 ml to 2500 ml. If your product range spans sizes outside these parameters, our engineering team can advise on the most suitable model from the full CMN ISBM machine lineup, including the Y150-V4 (smaller bottles) or the Y650-V4 (large format containers).

FAQ
Q: What is the difference between a one step ISBM machine and a two-step injection stretch blow molding machine?
A: A one step injection stretch blow molding machine like the Y250-V4 performs injection, preform conditioning, and stretch-blow molding in a single continuous cycle without any intermediate handling or reheating. A two-step system injects preforms in one machine, cools them completely, stores them, and then reheats them in a separate reheat stretch blow machine before blowing. The one-step process delivers superior product consistency, lower energy consumption (approximately 40% less than two-step), and a completely contamination-free production pathway, making it the preferred choice for pharmaceutical, food, and premium cosmetic packaging.
Q: Is the Y250-V4 a genuine replacement for ASB injection stretch blow molding machines?
A: Yes. The Y250-V4 is compatible with ASB-70DPH mold formats, which makes it a genuine compatible replacement for ASB ISBM machines. Facilities can transfer existing compatible molds to the Y250-V4 without modification in most cases. The Y250-V4 also offers measurable improvements over the original Japanese machines in parting-line quality (our molds produce no visible parting line), output cavity count (up to 6 per cycle vs. 4 on Japanese equivalents), and energy efficiency (15 to 25% lower power consumption).
Q: Can the Y250-V4 injection stretch blow molding machine produce pharmaceutical-grade bottles?
A: Yes. In its fully servo (YS250-V4) or fully electric (Y250-V4-EV) configurations, the machine operates without any hydraulic system, delivering a completely oil-free, pollution-free production environment that satisfies GMP standards. The servo motor-driven bottom cutting mechanism replaces pneumatic components, further improving cleanliness and cycle speed. Neck finish dimensions are held to very tight tolerances, ensuring reliable child-resistant and tamper-evident closure performance. Contact our technical team for specific GMP documentation and machine configuration recommendations for your regulatory environment.
Q: What bottle sizes and volumes can the Y250-V4 ISBM machine produce?
A: The Y250-V4 supports bottles with diameters from 30 mm (14-cavity configuration) to 200 mm (2-cavity configuration), heights from 100 mm to 220 mm, and maximum volumes from 30 ml to 2500 ml. Neck diameters range from 16 mm to 130 mm depending on the cavity count. The blow mold stroke is 75 + 75 mm and the blow core stroke is 300 mm, accommodating the full range of supported bottle heights. For specific bottle dimensions that fall outside the listed ranges, our engineering team can evaluate feasibility and advise on the most suitable machine model.
Q: How does the energy consumption of the Y250-V4 compare to Japanese and European ISBM machines?
A: The Y250-V4 consumes 15% to 25% less energy than comparable Japanese, European, and American injection stretch blow molding machines. This is achieved through three servo pump systems that only draw power proportional to actual demand (unlike fixed-speed hydraulic systems that run continuously at full power), nano far-infrared energy-saving heating rings on the screw and barrel, and the single-stage process that eliminates the reheating energy consumed by two-step machines. For a machine running 20 hours per day, this energy saving represents a significant annual operating cost advantage.
Q: What materials can the Y250-V4 single-stage injection stretch blow molding machine process?
A: The Y250-V4 can process PET, PETG, PP, PE (HDPE and LDPE), PC, PCT, PCTG, Tritan, PLA, ABS, PS, and other approved thermoplastics. Standard machines are optimized for PET and PETG. For other materials including PP, PC, Tritan, and PLA, specific screw designs, barrel temperature profiles, and mold configurations may be required. Our technical team will specify the correct configuration for your target material as part of the pre-sale consultation process. Customized screw options are available to optimize processing of your specific material grade.
Q: What is the typical lead time from order to delivery for the Y250-V4?
A: Standard lead time for the Y250-V4 is approximately 60 to 90 days from order confirmation and deposit receipt, depending on configuration, mold requirements, and current production scheduling. Machines with custom mold tooling or non-standard material configurations may require additional time. Customers are kept informed of production milestones throughout manufacturing. Factory acceptance testing (FAT) can be arranged at our facility prior to shipment. We provide complete export documentation and can assist with customs clearance coordination for international shipping.
Q: Does CMN provide on-site installation and operator training for the injection stretch blow molding machine?
A: Yes. CMN provides comprehensive on-site installation and commissioning services, with experienced engineers available to travel to your facility for machine setup. Operator training covers machine startup, parameter setting, mold change procedures, product quality inspection, routine maintenance, and troubleshooting. Remote technical support via video call is also available for faster response on minor issues after commissioning is complete. Our after-sales service team remains available throughout the machine service life for spare parts, technical advice, and process optimization support.
Q: What is the difference between the Y250-V4 standard model, the YS250-V4 servo model, and the Y250-V4-EV fully electric model?
A: The Y250-V4 standard model uses servo pump hydraulics for clamping and injection, providing a good balance of cost and performance for most applications. The YS250-V4 servo model uses servo-driven clamping and screw injection in addition to servo pump hydraulics, delivering higher precision, lower energy consumption, and better long-term stability for applications with tight dimensional requirements. The Y250-V4-EV fully electric model eliminates all hydraulic systems entirely, using electric drives throughout, making it suitable for GMP pharmaceutical, food-contact, and precision cosmetic applications where any risk of oil contamination is unacceptable.
Q: Can CMN provide a customized injection stretch blow molding machine for special bottle shapes or non-standard production requirements?
A: Yes. CMN offers customized injection stretch blow molding machine solutions for customers with non-standard bottle geometries, special material requirements, unusual cavity counts, or unique production line integration needs. Our engineering team can evaluate your specific requirements and propose a machine configuration, mold design, and process parameter set tailored to your product.

Avis clients
Kim Jae-won, Cosmetic Packaging, South Korea
"We installed the Y250-V4 ISBM machine about ten months ago for our cosmetic bottle production line here in South Korea. The product quality honestly blew us away. We had been running a Japanese ASB machine for years and the parting line issue was always a headache, especially with our premium skincare brand clients who demand invisible seams. The CMN machine has no visible parting line at all. Setup took about 8 days with the CMN engineer on site, and now we are running 6 cavities at full speed. No complaints at all about reliability."
Werner Hoffmann, Pharmaceutical Packaging, Germany
"I run a mid-sized pharmaceutical packaging facility in Germany and we switched from an AOKI machine to the Y250-V4 two years ago. The energy savings have been very significant, around 20% on our electricity bill for the same output volume. The fully servo option we chose means we operate in an oil-free environment which our GMP certification requires. What really impressed me was how quickly CMN responded when we needed a Parker valve replacement, the part arrived in four days. That kind of after-sales reliability matters for a production floor that runs 16 hours a day."
Rodrigo Almeida, Beverage Packaging, Brazil
"Ordering from CMN from Brazil was a bit nerve-wracking at first since I had not worked with a new ISBM machine supplier before. But the whole process was very smooth. All the documentation was complete, shipping was handled properly, and when the machine arrived and our customs cleared it, the CMN technician flew in within the week. We are producing PET water bottles now with 4 cavities per cycle and the output is very consistent. The PLC interface is easy to understand even for operators who have never used this type of machine. Very happy with the purchase."
Elif Arslan, Cosmetic Bottle Manufacturer, Turkey
"We needed a machine to produce PETG cosmetic bottles for export to Europe and the USA. The Y250-V4 with a 6-cavity mold has been running for about 14 months now in our factory in Turkey. The bottles come out with beautiful clarity, no defects, and very stable neck dimensions. Our European clients inspect samples on every shipment and we have not had a single batch rejection related to bottle quality since we switched. The logistics time from order to delivery was 65 days which was fine for our planning. Overall a very professional company to work with."
Priyanka Mehta, Pharmaceutical Packaging, India
"The CMN sales team was very patient with all my questions before I placed the order. I am a smaller manufacturer in India making ophthalmic bottles for domestic pharmaceutical companies and I was worried that the Y250-V4 would be too large for what I needed. The team walked me through the different models and we ended up with a Y250-V4 running 9-cavity ophthalmic molds at 28mm neck diameter. Output quality is excellent and the machine has been very stable. We have been running it for 8 months without any major downtime. Servicing has been handled remotely through video calls which works well."
Fatima Al-Rashid, Baby Products Manufacturer, Saudi Arabia
"I had been using an older Japanese machine for producing PP baby bottles for about six years. When it was time to upgrade, I looked at several injection stretch blow molding machine manufacturers and CMN gave the most detailed technical proposal with the clearest explanation of how their machine would perform with PP material. We have been running the Y250-V4 with a 4-cavity PP mold for babies feeding bottles for almost a year. The dimensional consistency is outstanding, our rejection rate on neck finish dropped by over 60% from what it was on the old machine. Very satisfied with the technical support throughout."
Carlos Vega, Contract Packaging, Mexico
"We are a contract packaging company in Mexico and we produce bottles for several different brand owners across beverage, personal care, and food segments. With a machine that can run PET, PETG, and PP on the same platform with mold changes is extremely valuable for our business model. The Y250-V4 has handled all three materials without issues over the past 16 months. We ran a full shift changeover between a PET water bottle mold and a PETG shampoo bottle mold in about 90 minutes with an experienced team. Very flexible machine overall."
Nguyen Thi Lan, Household Products, Vietnam
"We source packaging machinery regularly and logistics performance is always one of our concerns when importing from overseas suppliers. I will say CMN was very reliable on this front. The machine was crated and shipped according to schedule, the export documentation was clean and complete, and when we cleared customs in Vietnam the machine was in perfect condition. The installation was done remotely with step-by-step guidance which our local technician followed without problems. We produce dish soap bottles at 5 cavities per cycle and the daily output consistently hits our planning targets."
Tomasz Kowalczyk, Food Packaging, Poland
"Our company in Poland had been looking for a cost-effective replacement for our aging ASB-70DPH machine. We found CMN through an industry contact and the compatibility claim on the Y250-V4 turned out to be 100% accurate. We transferred three of our existing ASB molds to the new machine and they ran without modification. The production quality on the transferred molds was noticeably better than what we were getting from the old ASB, particularly on neck dimensional accuracy. That alone justified the investment. The price-to-performance ratio of the Y250-V4 is genuinely excellent compared to what European OEM machines would have cost for the same capability."
