Y280-V6 One Step Injection Stretch Blow Molding Machine (6-Station)

EBM | Extrusion Blow Molding

EBM starts with a hot hollow parison formed by an extruder. The mold closes around the parison, and compressed air expands the plastic into the mold cavity. This method is highly flexible for producing large containers, handled bottles, drums, and HDPE packaging where exact neck precision is less critical. Common materials include HDPE, LDPE, PP, and PVC.

The primary advantage of EBM is shape freedom. Parison extrusion can form handles, wide bodies, and offset shapes more easily than injection-based processes. However, parison sag under gravity can create uneven wall thickness, and the mold closing process often produces flash that requires trimming. For buyers, the main quality risks are inconsistent wall distribution around handles or shoulders and less precise neck thread definition.

IBM | Injection Blow Molding

IBM starts with an injection-molded preform where the neck, thread, and sealing area are formed with high dimensional precision before the bottle body is blown. The preform is transferred into a blow mold and inflated into its final shape. Because the neck geometry is established during injection before blowing, IBM produces exceptionally accurate thread definitions and closure sealing surfaces.

This precision matters most for small pharmaceutical bottles, eye-drop containers, cosmetic jars, and medical packaging where cap and pump fitment must be leak-free. IBM also produces consistent bottle weight and repeatable dimensions. However, IBM does not include a stretch rod, so the biaxial orientation benefits of the ISBM process are not achieved, making IBM less suitable for large or lightweight PET containers where strength and clarity at low wall thickness are priorities.

ISBM | Injection Stretch Blow Molding

ISBM is the process used in the Y280-V6. Like IBM, it starts with an injection-molded preform that establishes the neck geometry. But ISBM adds a stretch rod that extends the preform vertically before compressed air expands it outward. This biaxial orientation aligns the polymer molecules in two directions simultaneously, producing bottles with significantly improved clarity, top-load strength, gas barrier performance, and lightweight potential.

These properties are critical for PET water bottles, carbonated beverage packaging, edible oil containers, and clear cosmetic bottles where both performance and visual clarity matter. The single-stage injection stretch blow molding machine design of the Y280-V6 combines injection and blow molding in one continuous cycle without secondary preform reheating, achieving 15 to 25% energy savings compared to two-step systems while maintaining superior bottle quality and production speed.

Step 1: PET Resin Drying and Hopper Loading

PET resin for beverage bottle production must be dried to a moisture content below 50 ppm before processing to prevent hydrolytic degradation during melt injection. A dehumidifying dryer operating at 160 to 170 degrees Celsius for 4 to 6 hours is typically required. Dried PET pellets are loaded into the machine hopper, which feeds the injection screw. Undried PET produces bottles with reduced intrinsic viscosity, visible surface haziness, and reduced mechanical strength that can cause bottles to fail burst pressure or drop tests during quality control inspection.

Step 2: Preform Injection Molding

The dried PET resin is fed to the screw barrel, melted at temperatures typically between 270 and 285 degrees Celsius, and injected under precise pressure into the injection mold to form the beverage bottle preform. The preform shape, including the neck thread, sealing surface, and body wall thickness distribution, is determined at this stage. For carbonated beverage bottles, neck finish accuracy is especially critical because the crown or screw cap must seal reliably against the internal CO2 pressure of 2.0 to 4.5 bar. The preform is partially cooled to a stable but pliable temperature before transfer.

Step 3: Temperature Conditioning and Turntable Transfer

The servo-driven rotary turntable transfers the freshly injected preform from the injection station to the temperature conditioning zone. The integrated control box temperature system manages thermal equilibration across the preform body length to achieve a consistent temperature profile before stretching begins. For beverage bottles, the optimal preform temperature for biaxial ISBM stretching is typically 85 to 100 degrees Celsius, varying by bottle design and wall thickness target. Uneven preform temperature at this stage is the most common cause of shoulder thinning, base thickening, and pearl white opacity in the finished bottle.

Step 4: Biaxial Stretch Blow Molding

The conditioned preform enters the blow station where the mold closes around it and a stretch rod extends the preform vertically to the base of the blow mold. High-pressure air at 2.0 to 3.5 MPa is then introduced through the blow pin to expand the preform outward against the mold cavity walls simultaneously. This biaxial stretching step is what produces the superior strength and clarity characteristic of ISBM PET bottles. For carbonated beverage bottles, the resulting molecular orientation improves CO2 barrier performance, burst pressure resistance, and thermal stability during hot filling or pasteurization processes.

Step 5: Mold Cooling and Bottle Solidification

Following the blow molding stage, the bottle is held inside the closed mold while cooling water circulated through the mold channels removes heat from the container surface. Cooling time is a direct determinant of cycle time and dimensional stability. For beverage bottles where high clarity and low haze are commercial requirements, rapid and uniform cooling prevents crystallization that would make the PET appear white or translucent. The Y280-V6 cooling water circuit maintains temperature at 20 to 25 degrees Celsius through the machine oil cooler, providing stable cooling conditions across extended production runs.

Step 6: Ejection and Quality Inspection

After sufficient cooling, the mold opens and the take-out mechanism with 170 mm stroke removes the finished beverage bottle from the blow station. The ejected bottle is transferred to the inspection and downstream packaging area. Quality checks for beverage bottles typically include visual inspection for surface defects and clarity, neck dimension gauging for cap fitment, weight measurement for fill volume consistency, and periodic burst pressure and drop impact testing according to the customer's quality plan. Bottles that pass inspection proceed directly to the filling line, conveyor system, or packing station without any secondary trimming or surface treatment.

Step 7: Downstream Packing and Storage

Finished beverage bottles from the Y280-V6 production line are typically collected on conveyors, counted into specified lot quantities, and packed into corrugated cartons or plastic bags for shipment to the filling plant. For high-volume operations, automatic bottle counting and bagging systems can be integrated downstream of the ISBM machine ejection station. Bottles should be stored in clean, dry conditions away from direct sunlight and chemical vapors that could affect PET surface quality before filling. Proper downstream handling protects the investment in bottle quality that the ISBM process provides throughout the entire production chain.

Maintenance and Care

1. Daily Lubrication and Mechanical Checks
At the start of each production shift, inspect all lubrication points on the clamping unit, turntable bearing, and ejection mechanism. Apply grease to specified points according to the maintenance schedule provided in the machine manual. Check that the turntable rotation is smooth and that no unusual vibration or noise is present during indexing. Verify that all air cylinder rod seals are intact and that there is no air leakage at cylinder connections. Addressing minor lubrication deficiencies early prevents accelerated wear on precision components and avoids unplanned downtime during production runs.

2. Hydraulic System Oil Management
The 300-liter hydraulic oil tank should be checked weekly for oil level, color, and contamination. Fresh hydraulic oil is typically light amber; darkening or cloudiness indicates oxidation, water contamination, or particle contamination from worn seals. Replace hydraulic oil completely according to the manufacturer's scheduled interval, typically every 2,000 to 3,000 hours of operation. Clean or replace hydraulic oil filters at each oil change. Maintaining clean hydraulic oil is critical because the YUKEN hydraulic control valves and high-pressure components have tight internal clearances that are sensitive to particulate contamination, which causes valve sticking, erratic pressure behavior, and accelerated component wear.

3. Cooling Water Circuit Maintenance
The cooling water circuit should be inspected monthly for scale buildup, biological growth, and flow rate consistency. The machine oil cooler must maintain water temperature between 20 and 25 degrees Celsius and pressure between 0.3 and 0.4 MPa to keep hydraulic oil viscosity within the operating range. The mold cooling circuit operates at 0.4 to 0.6 MPa and must be monitored for blockages that could cause uneven mold cooling and dimensional variation in bottles. Use treated water or a closed-loop cooling system with corrosion inhibitor to prevent scale and corrosion that would reduce heat transfer efficiency and restrict flow through mold cooling channels over time.

4. Screw and Barrel Cleaning
The injection screw and barrel should be purged and cleaned whenever changing between resin types or colors, and at scheduled intervals during extended production runs of the same material. For PET and PETG, purge with a commercial purging compound or a compatible transition resin to remove degraded material from the screw flights and barrel walls. Degraded PET deposits can cause black specks, yellow streaking, or molecular weight reduction in the finished container if not removed. The nano far-infrared heating ring system heats the barrel uniformly, but stagnant material in low-flow zones can still degrade if the screw is left stationary at temperature for extended periods without purging.

5. Mold Inspection and Cavity Care
Mold tooling should be inspected at regular intervals for wear on the cavity surface, parting line, venting channels, and neck ring components. Clean cavity surfaces with approved mold release agents and plastic-safe solvents to remove resin deposits and oxidation. Inspect water channel connections on the mold for leaks or blockages and verify that the cooling circuit is balanced across all cavities. Misaligned or worn parting surfaces can create flash on bottles, which affects container appearance and may indicate clamping force imbalance. Store molds in climate-controlled storage with protective coating on metal surfaces when not in production to prevent corrosion and humidity damage.

6. Servo Motor and Electrical System Checks
The Inovance or WEICHI servo motors driving the Y280-V6 clamping and injection systems should be inspected quarterly for bearing temperature, encoder signal quality, and cable condition. Check servo drive units in the electrical cabinet for adequate ventilation and absence of dust buildup that could cause overheating or signal interference. The Inovance or MiRLE PLC should have its battery backup status checked annually to ensure parameter memory is retained during power outages. Review the PLC fault log monthly to identify recurring alarms that may indicate developing mechanical or electrical issues before they cause a production stoppage. All electrical connections should be retorqued at commissioning and at annual service intervals to prevent high-resistance contacts from developing.

Domande frequenti

Q: What is the difference between the Y280-V6 and a standard four-station injection stretch blow molding machine?
A: The Y280-V6 uses a six-station rotary turntable instead of the four-station design common in Japanese ISBM machines. This means the Y280-V6 can process six preforms simultaneously in a single rotation cycle, producing more bottles per cycle than a four-station machine running the same tooling configuration. In addition to higher output, the extra stations allow for longer temperature conditioning and cooling dwell times, which can improve bottle quality when running demanding materials or complex shapes.

Q: Can the Y280-V6 use existing ASB or Aoki injection stretch blow molding machine molds?
A: Yes. The Y280-V6 is designed to be compatible with mold tooling originally manufactured for Japanese ASB injection stretch blow molding machines, specifically ASB-12M and ASB-70DPH format molds. CMN's broader product range also includes models compatible with Aoki 100, Aoki 250, and Aoki 500 mold formats. This mold compatibility is a major commercial advantage for manufacturers who have existing tooling investment and want to switch to CMN equipment without the cost of replacing all their molds. Contact our sales team with your existing mold specifications to verify compatibility before purchase.

Q: Is a fully electric version of this one step injection stretch blow molding machine available?
A: Yes. CMN Transmission offers the Y280-V6 in a Fully Electric configuration that replaces all hydraulic drive systems with servo motors. The fully electric version produces no hydraulic oil, making it suitable for pharmaceutical manufacturing facilities that must comply with GMP standards and operate in clean-room-adjacent environments. The fully electric version also offers advantages in energy consumption, positioning repeatability, and quieter operation. It is available at a higher initial cost than the Standard or Servo hydraulic-assisted versions.

Q: What materials can the Y280-V6 PET injection stretch blow molding machine process?
A: The Y280-V6 is designed primarily for PET and PETG processing, which are the most common materials for ISBM production. However, the machine is also capable of processing PP, PC, Tritan, PPSU, PCTG, ABS, PS, and PLA with appropriate screw diameter selection, barrel temperature adjustment, and drying pre-treatment. Different materials require different processing parameters, and CMN's technical team can advise on the correct configuration for your specific material and bottle design before delivery.

Q: How much energy does the Y280-V6 single-stage injection stretch blow molding machine save compared to Japanese equivalents?
A: The Y280-V6 consumes 15% to 25% less energy than comparable Japanese, European, or American injection stretch blow molding machines running similar bottle designs and output volumes. This saving comes from three sources: the servo pump systems which only generate pressure on demand rather than running continuously at full flow, the nano far-infrared screw heating rings which reduce heat loss compared to conventional resistance heating, and the single-stage ISBM process which eliminates the secondary preform reheating step required by two-stage blow molding systems. Actual savings vary by bottle design, cycle time, and local utility rates.

Q: What bottle sizes and volumes can the Y280-V6 ISBM machine produce?
A: The Y280-V6 accommodates bottles from 20 ml to 2,500 ml in volume, with bottle diameters from 20 mm to 120 mm and bottle heights up to 210 mm. The machine can run from 1 to 10 cavities per cycle depending on bottle size, with neck diameters from 12 mm up to 85 mm. The product dimensions table provides the maximum bottle specifications at each cavity count. Custom bottle dimensions outside the standard table can be discussed with the CMN engineering team, who will assess mold feasibility and machine stroke compatibility before confirming the order.

Q: What is the difference between a one step ISBM machine and a two-step PET blow molding machine?
A: In a one step ISBM machine like the Y280-V6, the plastic resin is injected into a preform and immediately transferred to the stretch blow molding station within the same machine, retaining the heat from the injection phase. No separate preform reheating equipment is needed. In a two-step system, preforms are injection molded separately, stored and cooled completely, then reheated in a second machine before blow molding. The one-step process uses less energy because it avoids the preform reheating cycle, has a smaller footprint because only one machine is required, and produces bottles directly from resin pellets. The two-step system offers greater flexibility for high-volume commodity PET bottle production where preforms can be produced and stored separately for flexible output scheduling.

Q: How long does installation and commissioning of the Y280-V6 take?
A: Standard installation and commissioning of the Y280-V6 typically takes 3 to 5 days with a CMN technical team on site. The process includes machine positioning and leveling, electrical and pneumatic connection, cooling water circuit commissioning, hydraulic system priming and pressure setting, mold installation and alignment, and initial production trials with the buyer's material and tooling. Operator training covering machine setup, parameter adjustment, safety procedures, and basic maintenance is conducted in parallel during commissioning. Scheduling of the CMN installation engineer visit is coordinated at the time of machine delivery and depends on buyer readiness and the availability of all utilities and tooling on site.

Q: What compressed air supply does the Y280-V6 injection blow molding machine require?
A: The Y280-V6 requires a compressed air supply capable of delivering blowing air at 2.0 to 3.5 MPa (20 to 35 bar). A high-pressure compressor is required to achieve the upper end of this range for certain bottle designs or materials. The volume of air consumed per cycle depends on the bottle cavity volume and number of cavities, with larger or more numerous bottles requiring more air per cycle. Buyers should calculate the required compressor capacity based on their expected production speed and bottle volume before installation. An undersized compressed air supply is one of the most common causes of startup delays on new ISBM machine installations.

Q: Can the Y280-V6 produce BPA-free bottles for pharmaceutical and food contact applications?
A: Yes. The Y280-V6 processes BPA-free materials including PET, PETG, PP, Tritan, PPSU, and PCTG, all of which comply with major international food contact and pharmaceutical packaging regulations including FDA, EU 10/2011, and equivalent standards. For pharmaceutical applications where GMP requires complete elimination of hydraulic oil contamination risk, the fully electric servo configuration of the Y280-V6 is recommended. Buyers requiring specific material compliance documentation or food contact safety declarations for their end market should request the relevant certificates from CMN and from their resin supplier at the time of purchase.

Recensioni dei clienti

Kim Jae-won, Pharmaceutical Packaging, South Korea
"We installed the Y280-V6 in our pharmaceutical packaging facility in Seoul about fourteen months ago and honestly it has been one of the best equipment decisions we made. We produce 50 ml PET oral liquid bottles using 6-cavity tooling and the neck dimension consistency is really something. Our QC rejection rate on sealing surfaces dropped from about 1.2% to under 0.25% after switching from a Japanese ISBM machine. The energy bills also came down more than we expected - our plant engineer calculated around 22% reduction in electricity cost per thousand bottles produced. The CMN installation team spent four full days with us during commissioning. Very thorough."

Rajesh Mehta, Cosmetic Packaging, India
"I run a cosmetic packaging line in Mumbai and we switched to the Y280-V6 from an older Japanese one-step machine last year. The surface quality improvement is immediately visible. Our clients kept complaining about faint parting line marks on our 150 ml skincare bottles, and after switching to CMN tooling that problem completely went away. The Tritan and PETG processing has been very stable on this machine. Cycle times are shorter and the servo system is noticeably more responsive. I was worried about service support from a Chinese manufacturer but they have been quite responsive. Response to my WhatsApp messages usually comes within a few hours."

Ahmed Hassan, Beverage Packaging, Egypt
"We ordered two Y280-V6 units for our PET water bottle production line in Cairo. Delivery time was about 10 weeks from order confirmation which was acceptable. The machines arrived in good condition with proper export packing. Our existing Japanese ASB mold tooling transferred over without any modification which saved us a significant amount on new molds. Output per shift is higher than the four-station Japanese machines we were running before. The Arabic language support on the HMI interface would be a welcome addition but the English interface is manageable for our operators. Overall production costs have dropped and quality is consistent."

Fernanda Costa, Baby Packaging, Brazil
"Our company in Sao Paulo produces baby bottles in Tritan for the Brazilian retail market. We chose the Y280-V6 specifically because of the fully electric configuration option which we needed to comply with our GMP requirements. We have been running it for about 8 months now producing 120 ml baby bottles with 6 cavities. The dimensional consistency between cavities is very good - within 0.15 mm on neck diameter which is well within our tolerance. One thing I would say is that the spare parts documentation could be more detailed in Portuguese, but CMN were able to provide video tutorials for the main maintenance tasks which helped our technicians. Production output has been reliable."

Budi Santoso, Packaging Equipment, Indonesia
"I have been in the blow molding equipment business in Jakarta for over fifteen years and the Y280-V6 is genuinely competitive against the Japanese machines at a significantly lower price point. We purchased one for a client running hand wash bottles in PP and PETG and the results have been solid. Bottle weight consistency is excellent - within plus or minus 0.3 grams which the client is very happy with. The energy consumption data we have measured in practice confirms approximately 20% lower power use than the previous Japanese machine on the same bottle design. CMN handled the shipping and customs paperwork without issues. I will definitely recommend them to other customers."

Muhammad Khalid, Beverage and Food Packaging, Pakistan
"We manufacture PET juice and edible oil bottles in Lahore and evaluated three different injection stretch blow molding machine manufacturers before selecting CMN. The price was competitive but what really made the decision was the mold compatibility with our existing ASB tooling. We had six sets of molds already and were not prepared to invest in all new tooling. The transfer went smoothly and the bottles have been consistent since day one of production. Our logistics coordinator mentioned the shipping documentation from CMN was very well organized which made customs clearance faster than expected. Spare parts availability has been good - we have had two minor hydraulic valve replacements and both parts arrived within three weeks."

Nguyen Thi Lan, Cosmetic Packaging, Vietnam
"Our factory in Ho Chi Minh City produces cosmetic bottles for export markets and we have been running the Y280-V6 for about eleven months. We use it mainly for 200 ml and 300 ml PETG lotion and serum bottles, typically 4 to 6 cavities per run. The surface quality of the bottles is excellent - our European buyers who inspect samples have not raised any surface complaints since we switched to this machine. The servo response during injection is noticeably faster than our old hydraulic machine. Setup time when changing bottle designs is about 40 minutes which is acceptable for our production schedule. The CMN technician visited us twice in the first three months to fine-tune the process parameters. That level of support was much better than I expected."

Thabo Ndlovu, Beverage Packaging, South Africa
"We run a PET bottle production facility in Johannesburg supplying beverage brands across Southern Africa. The Y280-V6 was our first purchase from a Chinese ISBM machine manufacturer after many years of buying Japanese. The learning curve for our maintenance team was maybe two months before they were fully comfortable, mainly because they were used to the Japanese machine layout. Performance-wise the machines have run reliably. In twelve months we have had no major breakdown - only the standard planned maintenance. Bottle clarity and burst strength test results are within our spec. The main thing I would flag for other buyers is to plan for enough compressed air capacity because the Y280-V6 does use more air volume than older lower-pressure machines."

Carlos Ramirez, Contract Packaging, Mexico
"We are a contract packaging manufacturer in Mexico City and added the Y280-V6 to our line eighteen months ago. We produce body wash, shampoo, and hand sanitizer bottles for multiple clients in PET and PP from 250 ml to 1,000 ml. The six-station design was the main reason we chose it over competitor four-station machines because our clients expect fast delivery cycles. Actual production speed in our conditions has been very good. The PLC recipe storage is a useful feature for managing multiple bottle designs for different clients. One practical tip for other buyers - make sure your local compressed air supply is sized correctly for 3.5 MPa blowing pressure before installation. This tripped us up initially and delayed startup by about a week."
