Our Advanatges
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 amount 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.

By directly utilizing the residual heat from injection molding during the blow stage, secondary heating is eliminated, reducing power draw significantly across long production runs. Three servo pump systems replace constant-displacement hydraulic pumps, delivering power precisely when needed. The nano far-infrared energy-saving heating rings on the screw and barrel further reduce thermal losses. This sustainability focus reduces operating costs, lowers the carbon footprint of your packaging line, and aligns with increasingly stringent ESG reporting requirements in Europe, North America, and Australia.
4. High Production Efficiency
The integrated 4-station rotary turntable powered by a Japan Yaskawa or WEICHI servo motor with a Taiwan TSUNTIEN reducer ensures simultaneous operation across injection, conditioning, stretch-blow, and take-out stations. This parallel processing architecture maximizes throughput without sacrificing dimensional accuracy. The full automation of the production cycle, from resin feed to finished bottle ejection, eliminates manual intervention, reduces labor costs, and supports 24-hour continuous operation. With higher screw output volumes than comparable Japanese machines, the YS350-V4-EV can produce more bottles per cycle, delivering a measurably lower cost per bottle over the machine lifetime.
5. GMP Pharmaceutical Compliance

This replacement of AOKI injection stretch blow molding machines delivers equivalent or superior machine performance at a fraction of the acquisition and operating cost, with full after-sales support from Ever-Power engineering team. This backward compatibility substantially reduces the risk and capital required for equipment upgrades.
Working Principle of the Injection Stretch Blow Molding Machine
Step 1: Injection Molding
The process begins by heating PET or PETG resin to a molten state inside the plasticizing screw barrel. The 300 KN injection clamping force drives the molten polymer into the preform mold cavity under controlled pressure, forming a precise preform with a fully finished neck and thread geometry. The preform is partially cooled to structural stability while retaining sufficient internal heat for optimal stretch response. The neck finish is locked in its final dimensions during this stage, ensuring reliable sealing performance in the finished container. This stage sets the dimensional foundation for all downstream quality attributes, including volume accuracy and cap fitment.
Step 2: Preform Conditioning and Transfer
The rotary turntable, powered by a Yaskawa servo motor and Taiwan TSUNTIEN reducer, indexes the preforms from the injection station to the thermal conditioning zone. Temperature regulating cores and barrels maintain precise preform temperature profiles across the 300mm core stroke and 350mm barrel stroke. This controlled thermal conditioning phase equalizes heat distribution throughout the preform wall, ensuring that the PET molecular chains are in an optimal amorphous state for biaxial orientation in the next stage. Consistent preform temperature directly governs finished bottle wall uniformity, clarity, and barrier performance. Any deviation in this stage is corrected by the Inovance PLC control system in real time.
Step 3: Stretch Blow Molding
With a 250 KN blowing clamping force and a 2.0 to 3.5 MPa blowing air pressure range, the stretch-blow station transforms the conditioned preform into its final container geometry. A stretch rod extends the preform axially through the 300mm blow core stroke while high-pressure air simultaneously inflates it radially outward to fill the blow mold cavity (75 plus 75mm blow mold stroke). This biaxial molecular orientation significantly enhances container strength, gas barrier properties, impact resistance improvement, and optical clarity. The dual-servo motor mold clamping system with high-pressure compensation function ensures precise and consistent mold closure on every cycle, eliminating flash and maintaining dimensional tolerances across all cavity positions simultaneously.
Step 4: Cooling and Ejection
Once the container has been fully formed, the cooling water circuit (0.4 to 0.6 MPa, with oil cooler water maintained at 20 to 25 degrees Celsius) rapidly solidifies the bottle shape inside the closed mold. Rapid and uniform cooling is essential for maintaining bottle geometry, preventing warping, and shortening the overall cycle time. After the cooling period, the mold opens and the take-out station (175mm stroke) automatically extracts the finished bottles without human contact. The entire four-station cycle repeats continuously, producing a steady stream of ready-to-fill containers that require no post-processing, trimming, or reconditioning before they enter the filling line.

One-Step Injection Stretch Blow Mold Features
Preform Injection Mold
- Two-Part Die Lip Design
The die lip assembly is composed of two precision-machined parts that together guarantee coaxial alignment of the preform during formation. This coaxial design eliminates eccentricity in wall thickness distribution, which is a critical quality factor for containers with demanding thickness tolerances. The two-part assembly also simplifies die lip cleaning and polishing maintenance, reducing downtime associated with mold maintenance cycles. - Optimized Cooling Water Channels
The cooling water channel layout in the preform mold is engineered for maximum heat transfer coefficient across the entire preform surface. Efficient preform cooling shortens the injection cycle time while ensuring that the preform exits the injection station at the precise temperature profile required for optimal stretch-blow performance. Consistent preform temperature uniformity directly reduces bottle-to-bottle variation in wall thickness and optical properties across the entire production run. - Imported 2316 Die Steel
All mold formation components are manufactured from imported 2316 rust-resistant die steel that has undergone full heat treatment processing. This steel grade is specifically chooseed for its combination of corrosion resistance, polishability, and dimensional stability under repeated thermal cycling. The core plate and cavity plate use 420 stainless steel, providing superior corrosion resistance in high-humidity production environments and extending mold service life substantially compared to standard mold steel grades used in lower-cost competing products. - Multi-Preform Single Mold Capability
Advanced mold design allows a single injection mold to produce more than one preform configuration through modular core and cavity inserts. This design capability significantly reduces the total mold investment required for manufacturers who need to produce a diverse range of container sizes on the same machine. Standard interchangeable die fittings further simplify conversion between preform configurations, reducing changeover time and increasing production scheduling flexibility.
Blow Mold
- High-Quality Steel Construction
All blow mold components are machined from high-quality steel grades chooseed for blow mold applications, providing the hardness and wear resistance required for millions of production cycles. The raw material chooseion and heat treatment specifications are documented and traceable, providing quality assurance for pharmaceutical and food packaging applications that require material certification for regulatory compliance purposes. - Advanced 3D Design and CNC Machining
Every blow mold cavity is designed using advanced 3D CAD software that accurately models the final container geometry including draft angles, texture maps, label panel geometries, and cooling channel configurations. All metal components are then precision-machined on CNC equipment to ensure that the finished mold cavity exactly replicates the approved 3D model. This digital-to-physical workflow eliminates hand-fitting errors and ensures that all cavity positions within a multi-cavity mold produce identical containers. - Versatile Bottle Design Support

Operating Safety and Maintenance Tips
1. Pre-Startup Inspection
Before every production startup, verify cooling water pressure is within 0.4 to 0.6 MPa and oil cooler water temperature is between 20 and 25 degrees Celsius. Check hydraulic oil level in the 300-liter tank and inspect all servo motor connections and encoder feedback cables for secure seating. Verify that the Inovance PLC program version matches the active product recipe. Never operate the machine without verified cooling water flow, as thermal damage to mold components and the injection barrel can occur rapidly without adequate cooling.
2. Resin Handling and Drying
PET and PETG resins are hygroscopic and must be dried to below 0.005% moisture content before processing to prevent hydrolytic degradation during melting. Undried resin results in reduced molecular weight, degraded mechanical properties, and visible surface defects including haze and silver streaks in finished bottles. Use a desiccant dehumidifying dryer at 160 to 180 degrees Celsius for 4 to 6 hours for PET, or 70 to 80 degrees Celsius for 4 hours for PETG. Monitor hopper dryer temperature continuously and verify moisture level with a moisture analyzer before and during production.
3. Mold Installation and Alignment
Mold installation must be performed by trained technicians following the Ever-Power mold installation procedure document. Incorrect mold alignment causes uneven clamping force distribution, parting line flash, and premature mold wear. Use calibrated torque wrenches for all mold mounting bolts and verify mold parallelism with a dial indicator before startup. After any mold change, run a minimum of 50 dry cycles without resin to verify mechanical clearances before introducing material. Document all mold changeover parameters in the machine logbook for traceability.
4. Servo Motor and Drive Maintenance
The servo motors and drives on the YS350-V4-EV are high-precision components that require periodic preventive maintenance to maintain positioning accuracy and torque output consistency. Check servo motor cooling fins for dust accumulation every 500 operating hours. Verify drive parameter settings quarterly against the factory baseline parameter sheet. Replace servo motor encoder batteries according to the Inovance or WEICHI maintenance schedule. Any unusual servo alarm codes should be investigated immediately and not reset without identifying and resolving the root cause.
5. Hydraulic System Management
The hydraulic system uses the Taiwan YUKEN control valve and Parker high-pressure valve components. Change hydraulic oil at the interval specified in the maintenance schedule, typically every 2,000 to 4,000 operating hours depending on operating temperature. Replace hydraulic oil filters at every oil change. Monitor hydraulic system pressure gauges for signs of internal valve wear or pump degradation. Never exceed the rated system pressure and investigate any unexplained pressure fluctuations immediately, as hydraulic system instability directly affects clamping force consistency and bottle dimensional accuracy.
6. Emergency Stop and Safety Procedures
All operators must be trained on the machine emergency stop procedure and the location of all safety interlock switches before being authorized to operate the YS350-V4-EV. During any mechanical jam, never attempt manual extraction of preforms or bottles while machine power is active. Always engage the emergency stop and follow lockout-tagout procedures before any manual intervention in the machine workspace. Safety guard doors must be closed and interlocked during all automated operation cycles. Any safety interlock bypass is strictly prohibited and may result in machine damage and serious personal injury.
Injection Blow Molding vs. Injection Stretch Blow Molding
As the packaging industry continues to evolve, manufacturers are constantly seeking the most efficient and cost-effective technologies for producing plastic containers. At Ever-Power, a leading injection stretch blow molding machine manufacturer, we frequently receive questions comparing Injection Blow Molding (IBM) with Injection Stretch Blow Molding (ISBM). Understanding these two processes is essential for businesses aiming to optimize their production lines and deliver high-quality plastic bottles and containers at competitive costs.
What is Injection Blow Molding (IBM)?
Injection Blow Molding is a two-step process that combines the precision of injection molding with the forming efficiency of blow molding. Molten plastic is injected into a mold cavity to form a parison or preform that already incorporates the finished neck and thread geometry. This preform is then transferred to a blow mold, where compressed air inflates it to the desired container shape. IBM does not incorporate a mechanical stretching step, which means polymer chains are not biaxially oriented in the finished container.
At Ever-Power, our advanced injection blow molding machine (IBM machine) range is engineered for producing small, intricate bottles, including those used in pharmaceutical, cosmetic, and personal care applications. The process achieves excellent dimensional accuracy and is ideal for containers requiring tight tolerance neck finishes and consistent wall distribution on relatively small container sizes.
Key Features of Injection Blow Molding:
- High precision and uniform wall thickness on small-format containers
- Ideal for small to medium-sized containers (typically under 500ml)
- Excellent for complex neck finish and thread designs
- Minimal post-processing required
- Compatible with HDPE, PP, and PVC resins
What is Injection Stretch Blow Molding (ISBM)?
Injection Stretch Blow Molding adds a critical third step to the IBM process: mechanical stretching. After the preform is injection-molded, a stretch rod extends the preform axially while compressed air simultaneously inflates it radially. This biaxial stretching aligns the polymer molecular chains in two directions, dramatically improving the mechanical properties and optical characteristics of the finished container. ISBM is the dominant process for manufacturing PET bottles used in beverage, food, pharmaceutical, and premium cosmetic packaging.
As a prominent ISBM machine manufacturer, Ever-Power offers the YS350-V4-EV and a comprehensive range of one step ISBM machines that integrate injection, conditioning, stretch-blowing, and take-out in a single-stage platform. This one-step architecture eliminates the reheat step required by two-stage ISBM systems, preserving the inherent heat energy from injection molding for the blow stage and reducing energy consumption by 15-25% versus conventional reheat stretch blow molding equipment.
The YS350-V4-EV as a full electric injection stretch blow molding machine configuration also eliminates hydraulic oil from the blow zone entirely, meeting the cleanroom and GMP compliance requirements of pharmaceutical manufacturers worldwide. The machine supports a wide container range from 20ml eye care bottles to 2,500ml wide-mouth jars, making it one of the most versatile customized injection stretch blow molding machines available in the market today.

FAQs
Q1: What makes the YS350-V4-EV a suitable replacement for the Japanese AOKI AL-350LL-40 machine?
A: The YS350-V4-EV is mechanically compatible with existing AOKI AL-350LL-40 mold tooling, which allows manufacturers to transfer their existing mold investment directly to the new machine without additional tooling costs. In addition, the YS350-V4-EV delivers higher production output per cycle, 15-25% lower energy consumption, comparable or superior bottle surface quality with near-invisible parting lines, and full after-sales support from Ever-Power engineering team. The standardized design using internationally sourced components also simplifies global spare parts procurement compared to Japanese OEM-proprietary components.
Q2: What bottle sizes can the YS350-V4-EV produce?
A: The YS350-V4-EV supports production of containers from 20ml (12-cavity configuration at 26mm bottle diameter) up to 2,500ml (single-cavity configuration at 118mm bottle diameter). The machine accommodates 1 to 12 cavities per cycle depending on the container size, and can produce containers with bottle heights up to 280mm in single-cavity configuration. This wide production range makes the YS350-V4-EV suitable for pharmaceutical eye care drops, cosmetic serums, food condiment bottles, beverage containers, and large-format chemical packaging on a single machine platform.
Q3: Is the YS350-V4-EV compliant with GMP pharmaceutical packaging standards?
A: Yes. The YS350-V4-EV is designed to meet GMP pharmaceutical packaging production standards. The fully enclosed production cycle prevents human contact with containers from raw material to finished bottle. The full electric servo configuration option eliminates hydraulic oil from the blow zone, satisfying cleanroom and oil-free environment requirements for pharmaceutical manufacturing facilities. The machine has been successfully deployed in pharmaceutical packaging operations in multiple countries and has passed customer GMP facility audits. Please contact Ever-Power for a detailed technical dossier on GMP compliance specifications.
Q4: What is the difference between a one-step ISBM machine and a two-stage ISBM machine?
A: A one-step ISBM machine (like the YS350-V4-EV) integrates injection molding, preform conditioning, stretch-blow molding, and bottle ejection on a single machine platform. The preform is blow-molded immediately after injection without being fully cooled to room temperature, retaining the residual heat from injection for the blow stage. This eliminates the secondary reheating step required by two-stage ISBM systems, reducing energy consumption by approximately 40% for the heating phase and enabling production of complex shapes and special-profile containers that are difficult or impossible to produce on two-stage equipment.
Q5: What resins are compatible with the YS350-V4-EV injection stretch blow molding machine?
A: The YS350-V4-EV is optimized for PET and PETG resins, which are specified in the machine technical documentation. The machine can also be configured for processing PP, HDPE, PVC, PS, ABS, and PC resins depending on the application requirements, screw configuration, and temperature control settings. Please consult with Ever-Power engineers to verify material compatibility and any required machine configuration adjustments for resins outside the standard PET and PETG specification before placing a purchase order.
Q6: How much energy does the YS350-V4-EV consume compared to Japanese ISBM machines?
A: The YS350-V4-EV consumes 15-25% less energy than equivalent Japanese, European, and American one-step ISBM machines. This saving is achieved through the three servo pump system that provides hydraulic power on-demand rather than continuously, the nano far-infrared energy-saving heating rings on the screw and barrel, and the elimination of secondary reheating by using residual injection heat for the blow stage. With a motor power of 49.2 KW and heating power of 15 KW (total 64.2 KW), the actual consumption per bottle produced is significantly lower than conventional hydraulic machines of comparable capacity.
Q7: Can I use my existing AOKI AL-350LL-40 molds on the YS350-V4-EV?
A: Yes, the YS350-V4-EV is designed to be compatible with Japanese AOKI AL-350LL-40 mold tooling. This direct compatibility allows manufacturers to avoid the cost of fabricating new mold tooling when transitioning from AOKI equipment to the YS350-V4-EV. Before finalizing your purchase, we recommend sharing your existing mold drawings or AOKI machine specifications with Ever-Power engineers for a formal compatibility verification to verify that your specific mold tooling will fit without modification. In most cases, the mold transfer is direct, but minor adapter plates may occasionally be required depending on mold generation and configuration.
Q8: What after-sales support does Ever-Power provide for the YS350-V4-EV?
A: Ever-Power provides comprehensive after-sales support including on-site installation and commissioning services, operator training covering machine operation, parameter programming, and routine maintenance procedures, remote technical troubleshooting via video link with English and Mandarin-speaking engineers, and a structured preventive maintenance schedule tailored to your production environment. Spare parts including servo motor components, heating elements, hydraulic seals, and mold wear parts are stocked and can be shipped globally with short lead times. Ever-Power also offers optional extended warranty and annual maintenance contract programs.
Q9: How does the YS350-V4-EV achieve near-invisible parting lines on finished bottles?
A: The near-invisible parting line on bottles produced by the YS350-V4-EV is achieved through the extremely tight dimensional tolerances maintained by CNC-machined mold cavities and the 250 KN dual-servo motor mold clamping system with high-pressure compensation function. The servo-controlled clamping force distributes evenly across the full mold face area, eliminating the micro-gaps at the mold parting surface that allow molten material to flash and produce visible parting line protrusions. The mold tooling is manufactured from high-quality steel with precisely machined parting surfaces ground to within micron-level flatness tolerances, producing a nearly seamless bottle appearance.
Q10: Can the YS350-V4-EV produce containers with complex shapes and custom designs?
A: Yes. As a fully customized injection stretch blow molding machine, the YS350-V4-EV supports a wide range of complex container geometries that two-stage ISBM systems cannot produce, including asymmetric bottle profiles, oval and rectangular cross-sections, integrated handles, custom shoulder geometries, and special-shaped decorative containers. Ever-Power mold design team can work from customer CAD files or physical bottle samples to engineer mold tooling for any container geometry that falls within the machine envelope specifications. Custom bottle prototyping and mold development services are available, and sample production can be arranged before committing to high-volume production molds.
Customer Reviews
Ahmad Reza K. | Pharmaceutical Packaging | Iran
"We switched from our AOKI AL-350LL-40 to the YS350-V4-EV about eight months ago and honestly we were skeptical at first. The price point seemed too good. But after running this machine on our 50ml pharmaceutical oral liquid line with 8 cavities, I can say the bottle dimension consistency is excellent. Our GMP audit team inspected the production environment and approved it without any additional requirements. The Ever-Power installation engineer stayed on-site for five days to make sure everything was properly commissioned and our operators were trained. Very impressed."
Carlos M. | Cosmetic Packaging | Mexico
"Purchased two YS350-V4-EV machines for our cosmetic bottle production facility in Guadalajara. We produce 100ml to 500ml PET serum and lotion bottles for export to US and European markets. The surface quality on the bottles is genuinely beautiful, you cannot see any parting line which was always a problem with our previous equipment. Production output is also higher than what the Japanese machine was giving us. Energy bill has gone down noticeably since we commissioned these machines six months ago. Logistics from Mexico Ever-Power was smooth and documentation for customs clearance was complete."
Priya S. | Personal Care Manufacturing | India
"We have been running this machine for about a year now on a 200ml PETG cosmetic container project. The mold compatibility with our existing AOKI tooling saved us a significant amount on tooling costs when we transitioned. Setup was straightforward, the PLC interface is user-friendly, and the Inovance servo system has been rock solid. We had one minor hydraulic valve issue around month four and the after-sales team diagnosed it remotely and shipped the replacement Parker valve within three days. That kind of support is what keeps us coming back to Ever-Power for future machine purchases."
Marek W. | Food Packaging | Poland
"I manage procurement for a mid-size food packaging company in Poland. We bought the YS350-V4-EV to produce 350ml PETG condiment bottles and have been running it for about ten months. The machine runs consistently 22 hours per day and the output quality is very uniform. What I did not expect was how straightforward the maintenance procedures are compared to the older Japanese equipment we retired. The spare parts are also affordable and available quickly through the European distributor network that Ever-Power has established. Would definitely recommend to other food packaging operators."
Dewi R. | Household Care Manufacturing | Indonesia
"Our factory in Bandung produces shampoo and conditioner bottles for several major Indonesian personal care brands. We purchased the YS350-V4-EV model with the 50mm screw option and configured it for a 4-cavity 300ml oval bottle. The machine has been running for 14 months and the bottle weight consistency is within plus or minus 0.3 grams which satisfies our brand owner quality requirements. The energy consumption compared to our old hydraulic machine is noticeably lower which helps our factory electricity cost management. After-sales service response from Ever-Power is prompt and professional."
Marco B. | Ophthalmic Pharmaceutical | Italy
"We produce eye care bottles and nasal spray containers for a pharmaceutical client in Germany. When we evaluated the YS350-V4-EV we were particularly focused on whether the production environment would satisfy the client GMP audit requirements. The full servo electric configuration with no hydraulic oil in the blow zone passed the client facility audit without any non-conformances. The 12-cavity configuration for our 15ml ophthalmic bottle runs at excellent efficiency. The neck dimension consistency is critical for our dropper tip fitment and we have had zero leakage complaints since commissioning eleven months ago."
Sophie D. | Contract Packaging | Belgium
"First time buying from Ever-Power and I was nervous about purchasing capital equipment from a supplier I had not worked with before. The sales team was transparent about lead time, shipping costs, and commissioning requirements from the start. The machine arrived complete with all documentation including CE-compliant electrical schematics which was important for our facility approval process in Belgium. The commissioning engineer was knowledgeable and patient during operator training. We have been producing 750ml PETG bottles for a personal care brand for seven months and have had no significant downtime. Would buy from them again."
Jose L. | Beverage Packaging | Mexico
"We run a beverage bottle manufacturing operation in Guadalajara and evaluated multiple ISBM machine suppliers before choosing the YS350-V4-EV. The deciding factor was the AOKI AL-350LL-40 mold compatibility since we had a set of existing AOKI molds we wanted to reuse. The mold transfer worked exactly as Ever-Power described and we were producing bottles within 48 hours of machine installation completion. The production speed on our 500ml PET water bottle is faster than what we were getting on the AOKI machine. Overall very happy with the value for money and the quality of the bottles."
Kim J. | Baby Product Packaging | South Korea
"Purchased one YS350-V4-EV for our baby bottle production line in Seoul. We produce 150ml PETG baby bottles with 6 cavities per cycle. The optical clarity on the PETG bottles is genuinely impressive and matches what we were achieving on European equipment at a fraction of the machine cost. The bottle wall thickness uniformity is verified by our in-house ultrasonic thickness gauge and shows very tight distribution across all six cavity positions. The Ever-Power engineering support team has responded to all our technical inquiries within 24 hours, which is important for keeping our production schedule on track."
