Y150-V4 One Step Injection Stretch Blow Molding Machine (4-Station)

Step 1: Injection Process

Molten plastic resin, such as PET pellets, is fed into the screw barrel and homogenized under controlled temperature and back-pressure. The plasticized melt is then injected into the preform mold cavity at precisely regulated injection speed and pressure. The screw diameter options (40 mm to 60 mm) allow injection volumes from 188 cm³ to 480 cm³ per shot, covering a broad range of product weights. Accurate control of mold temperature and fill uniformity at this stage ensures every preform exits with consistent wall distribution, which is the foundation of final bottle quality.

Step 2: Temperature Conditioning

Unlike two-stage systems that allow the preform to cool completely before a separate reheat cycle, the Y150-V4 transfers the preform while it still retains its injection heat. A dedicated temperature-conditioning station with 250 mm core stroke and 230 mm barrel stroke fine-tunes the thermal profile across the preform body, ensuring the material reaches the precise stretching window for each resin type. This single-step thermal management is the primary mechanism behind the 40% energy saving advantage over conventional two-stage injection blow molding machine processes.

Step 3: Stretching Process

The temperature-conditioned preform is transferred to the blow mold station, where a stretch rod extends axially through the preform with controlled speed and force. This longitudinal orientation aligns the polymer molecular chains along the axial direction, a critical step that boosts tensile strength and clarity in the finished bottle. The 200 KN blowing clamping force (single side) and 250 mm blow-core stroke provide ample mechanical authority to handle high-viscosity resins and wide-neck containers with uniform wall control throughout the stretch phase.

Step 4: Blow Molding and Cooling

Compressed air at 2.0 to 3.5 MPa inflates the axially stretched preform radially against the inner wall of the closed blow mold, simultaneously orienting polymer chains in the hoop direction to create biaxially oriented plastic. The blow mold stroke of 75 + 75 mm provides symmetric clamping that eliminates flash and maintains tight dimensional tolerance on the bottle exterior. Cooling channels embedded in the mold rapidly extract heat from the bottle wall, solidifying the shape and locking in the enhanced mechanical and barrier properties achieved during biaxial orientation. The completed bottle is then ejected via the 170 mm take-out stroke mechanism for downstream conveyance.

When to Choose an ISBM Machine: Manufacturers should specify an injection stretch blow molding machine when the product demands superior clarity, enhanced gas-barrier performance, high-speed high-volume output, and the lowest possible material cost per container. Stretch blow molding dominates beverage bottle production because the biaxial orientation makes PET containers that weigh 10 to 15 percent less than equivalents from other processes while outperforming them in mechanical tests. A customized injection stretch blow molding machine such as the Y150-V4 further extends this advantage by supporting mold compatibility with ASB and AOKI tooling, reducing total capital expenditure for manufacturers upgrading from Japanese equipment.

When to Choose an IBM Machine: Injection blow molding remains the process of choice for small, high-precision containers under 100 ml where wall thickness accuracy is paramount and throughput requirements do not justify the capital investment of a full ISBM platform. Pharmaceutical vials, eye-drop bottles, and small cosmetic jars are typical candidates. CMN's product portfolio also includes injection blow molding machine models for customers whose product mix spans both process categories.

Features of the Y150-V4 Injection Stretch Blow Molding Machine

1. One-Step Processing
The Y150-V4 consolidates injection, temperature conditioning, stretching, and blowing into a single continuous four-station cycle. Eliminating intermediate storage or material transfer between process stages removes a major source of preform contamination, handling damage, and thermal inconsistency, resulting in better product quality at lower total operating cost compared to two-stage injection blow molding equipment.

2. Automatic Control System
The Inovance/MiRLE PLC controls every machine axis, temperature zone, and timing function through a touchscreen HMI. Production recipes can be named, saved, and retrieved for rapid format changeover with minimal setup scrap. Alarm logging and production counters allow supervisors to monitor efficiency and troubleshoot issues remotely, supporting Industry 4.0 integration goals for modern smart-factory environments.

3. Servo-Driven System
Three servo pump systems powered by Inovance or WEICHI servo motors (43.2 KW total) replace conventional fixed-displacement hydraulic pumps, delivering hydraulic flow and pressure precisely on demand. This architecture eliminates throttling losses and reduces heat generation in the hydraulic oil, cutting energy consumption during idle and low-load periods. The servo model (YS150-V4) extends this principle to all clamping and injection functions for maximum energy efficiency.

4. Vertical Working Mode
The four-station rotary turntable operates on a vertical axis, allowing the preform to move sequentially through injection, conditioning, stretching, and blowing stations within a compact horizontal footprint. This layout enables the use of gravity during the blowing phase for uniform base formation and simplifies mold alignment. The turntable is driven by a Yaskawa servo motor paired with a Taiwan TSUNTIEN reducer for index-precision positioning at every station.

5. Compact Machine Structure
At 4,200 mm x 1,400 mm x 2,900 mm and weighing only 6 tonnes, the Y150-V4 occupies far less floor space than equivalent two-stage production lines. The compact design simplifies factory layout planning, reduces crane requirements for installation, and allows multiple machines to be arranged in close proximity for efficient operator management, making it particularly suitable for production facilities with premium floor-space costs or limited ceiling height clearances.

6. One Mold with Multiple Cavities
The Y150-V4 supports up to 8 cavities per mold set, enabling simultaneous production of 8 bottles per cycle while maintaining the individual cavity control needed for uniform quality. Multi-cavity molds for the same machine reduce per-unit cycle time proportionally, delivering a throughput advantage that makes the one step ISBM machine competitive with much larger two-stage blow molding systems without the associated infrastructure investment.

7. Various Product Molding Types
The Y150-V4 handles round bottles, oval containers, square bottles, special-shaped craft bottles, and wide-neck jars. Bottle volumes span from 20 ml miniature dropper vials to 2,500 ml large-format containers in a single machine configuration. This versatility allows converters serving multiple end-market segments to consolidate diverse production requirements onto a single platform, reducing mold inventory capital expenditure compared to operating separate dedicated machines.

8. Extensive Raw Material Compatibility
The Y150-V4 processes PET, PETG, PP, PC, Tritan, PS, ABS, and PLA, as well as PCTG and engineering copolyesters. The programmable servo-controlled temperature management system allows operators to dial in precise melt and mold temperatures for each resin type, eliminating the need to purchase material-specific machines. This breadth of material compatibility makes the customized injection stretch blow molding machine a future-proof investment as material specifications evolve.

Operating Safety and Maintenance

1. Pre-Start Inspection
Before each production run, verify that cooling water pressure is within the 0.4 to 0.6 MPa specification, oil cooler temperature is between 20 and 25 degrees Celsius, and hydraulic oil level is within the sight glass range. Confirm that all safety guards and interlocks are securely in position. Inspect the Italian oil tubes for any signs of seepage at fittings and tighten as needed. A structured pre-start checklist reduces the risk of unplanned downtime caused by marginal operating conditions going undetected.

2. Resin Drying Protocol
PET and PETG resins are hygroscopic and must be dried to a moisture content below 0.005% (50 ppm) before processing in the injection unit. Processing undried resin causes hydrolytic degradation of the polymer chains, resulting in brittle bottles, surface streaking, and reduced molecular weight. Use a dehumidifying dryer at the temperature and dwell time specified by the resin manufacturer, and never load undried material directly from a sealed bag that has been stored in a humid environment without pre-conditioning.

3. High-Pressure Air Safety
The blow molding circuit operates at pressures up to 3.5 MPa. Never open blow-air fittings or adjust American Parker valve settings while the system is pressurized. Depressurize the accumulator and high-pressure circuit completely before performing maintenance on the blow pin, blow core, or associated pipework. All personnel working near the blow station should wear appropriate eye protection. Air-line filters and regulators must be inspected monthly for blockage and corrosion to maintain consistent blowing performance and prevent sudden pressure failures.

4. Mold Change Procedure
Always follow the lock-out and tag-out (LOTO) procedure before removing or installing mold sets. Ensure the injection clamping unit is fully retracted and the turntable is indexed to the mold-change position as defined in the machine manual. Use the provided lifting fixtures for mold handling to avoid dropping mold components, which can damage precision cavity surfaces. After installation, verify mold alignment with a dial indicator before starting a trial run, and purge the injection unit with fresh resin before recording final process parameters for the new format recipe.

5. Hydraulic Oil Maintenance
The 300 L hydraulic oil tank should use the grade recommended in the CMN maintenance manual. Oil samples must be analyzed every 2,000 operating hours for viscosity, acid value, and particle contamination. Replace the oil and all hydraulic filters at the first sign of degradation or after the manufacturer-specified service interval, whichever comes first. The YUKEN pressure-control valves are sensitive to contaminated fluid; using dirty oil leads to valve spool sticking, pressure fluctuation, and inconsistent clamping force, all of which compromise bottle quality and accelerate valve wear.

6. Electrical and Control System Care
The Inovance/MiRLE PLC cabinet and servo motor drives must be kept dry and free from plastic dust buildup. Clean the cabinet vents and heat sinks with compressed air quarterly. Inspect all cable connectors on the turntable servo motor harness for fretting wear caused by rotation, and replace any cable showing insulation cracking. Back up the PLC recipe database onto an external device monthly to protect production parameters in the event of a control board failure. Unauthorized modification of PLC logic invalidates the machine warranty and may create unsafe operating conditions.

Часто задаваемые вопросы

Q: What is the difference between a one step injection stretch blow molding machine and a two-stage blow molding process?
A: In a one step ISBM machine, the preform is injected, temperature-conditioned, stretched, and blown all within a single continuous machine cycle without the preform ever leaving the equipment or cooling to room temperature. A two-stage process first produces preforms on a separate injection molding machine, stores them, and then reheats and blows them on a separate reheat stretch blow molding machine. The single-stage process saves the energy cost of reheating (up to 40% energy reduction) and eliminates handling damage and contamination during storage and transfer, resulting in higher bottle quality at a lower operating cost per unit.

Q: Is the Y150-V4 a direct replacement of AOKI injection stretch blow molding machines?
A: Yes. The Y150-V4 is fully compatible with Japanese AOKI 100 molds and the Y150-V4-B model is compatible with the AOKI 100 format as well. Additionally, the standard Y150-V4 is engineered as a replacement of ASB ISBM machine tooling (ASB-12M). Customers can install their existing AOKI or ASB mold sets directly onto the CMN machine, eliminating the need to invest in new tooling. CMN's technical team can verify mold compatibility and advise on any required interface hardware before order confirmation. Customers transitioning from AOKI 250 or ASB-70DPH platforms should inquire about the Y250-V4 series instead.

Q: What materials can the Y150-V4 PET injection stretch blow molding machine process?
A: The standard Y150-V4 processes PET and PETG as its primary resins. The machine's screw design and temperature control system can also handle PP, PC, Tritan (Eastman copolyester), PS, ABS, and PLA with the appropriate screw diameter selection and temperature profile adjustment. For applications requiring engineering resins such as PCTG or high-clarity copolyesters, CMN can advise on specific screw geometry options. Note that the fully electric Y150-V4-EV is the preferred configuration for pharmaceutical-grade resins where zero hydraulic oil contamination is mandatory.

Q: How many bottles per hour can the Y150-V4 ISBM machine produce?
A: Throughput depends on cavity count, bottle volume, wall thickness, and cycle time. With a 6-cavity mold configuration producing 100 ml bottles, the Y150-V4 can reach approximately 3,600 to 4,800 bottles per hour depending on material and cooling conditions. For smaller 20 to 30 ml bottles in an 8-cavity mold, throughput can be proportionally higher. CMN's application engineering team can estimate expected hourly output for your specific bottle specification before purchase, allowing accurate ROI calculation.

Q: What is the difference between the standard Y150-V4, the servo YS150-V4, and the fully electric Y150-V4-EV?
A: The standard Y150-V4 uses three servo hydraulic pump systems for clamping and injection with a total motor power of 43.2 KW. The servo YS150-V4 replaces more of the hydraulic functions with direct servo motor actuation for lower energy consumption, higher precision, and faster response times. The fully electric Y150-V4-EV uses 10 sets of servo motor control systems with a total power of 102.8 KW and operates with no hydraulic oil circuit at all, meeting GMP and clean-room production requirements. The EV model is specified for pharmaceutical packaging, baby products, and food-contact applications where oil contamination is unacceptable.

Q: Can CMN supply a customized injection stretch blow molding machine for special bottle shapes?
A: Yes. CMN offers customized injection stretch blow molding machine configurations for special-shaped bottles including oval, square, asymmetric, and wide-mouth formats. Custom mold design and development is part of CMN's service portfolio. Customers can provide 3D CAD drawings or physical bottle samples for CMN's mold engineering team to quote and produce a compatible mold. CMN's mold manufacturing facility maintains close dimensional tolerances and performs factory acceptance testing on each mold set before shipment to ensure it meets the customer's specification.

Q: What utility supply does the Y150-V4 require for installation?
A: The Y150-V4 requires a three-phase power supply at 370 to 400 V and 50/60 Hz with sufficient amperage for the 53.2 KW total installed power. Compressed air at a stable supply pressure sufficient to maintain the machine's working range of 2.0 to 3.5 MPa at the blow valve inlet is required (a dedicated high-pressure air compressor is typically specified separately). Cooling water supply at 0.4 to 0.6 MPa and inlet temperature below 25 degrees Celsius is also required. CMN's installation guide provides detailed utility specification drawings for electrical, compressed air, and cooling water connection points.

Q: How does the Y150-V4 compare with other ISBM machine manufacturers in terms of cavity count?
A: The Y150-V4 supports up to 6 simultaneous production cavities, compared to a maximum of 4 cavities on Japanese ASB-12M equipment in the same size class. This 50% cavity-count advantage translates directly into proportionally higher output from the same floor space and labor input. CMN achieves this through improved mold-platen size and optimized turntable indexing speed. For customers currently operating Japanese equipment and considering an upgrade, the additional output capacity often recovers the machine investment cost within a shorter payback period than equivalent Japanese replacements.

Q: Does the Y150-V4 single-stage injection stretch blow molding machine produce bottles without a parting line?
A: Yes. CMN's proprietary mold manufacturing precision eliminates the visible parting-line protrusion that is a recognized characteristic of Japanese ASB-series bottles. The extremely tight cavity-to-cavity alignment in CMN's mold tooling means the parting line is present but invisible to the naked eye in standard lighting conditions, which is a critical quality advantage for high-end cosmetic, personal care, and premium food products where bottle appearance directly influences consumer purchase decisions. Customers requiring sample bottles for visual inspection and comparison can request production samples from CMN before placing a mold order.

Q: What are the smallest and largest bottle the Y150-V4 can produce?
A: The Y150-V4 can produce bottles as small as 20 ml (with an 8-cavity mold, 26 mm bottle diameter, 15 mm neck diameter) and as large as 2,500 ml (with a single-cavity mold, 118 mm bottle diameter, 83 mm neck diameter). Bottle height ranges from 100 mm to 210 mm depending on cavity count and mold configuration. This wide range covers the majority of personal care, pharmaceutical, food, and beverage bottle formats without requiring a machine change, making the Y150-V4 a genuinely versatile platform for multi-product packaging converters.

Park Joon-ho, Plant Manager, Cosmetic Industry, South Korea
"We replaced our old ASB-12M with the Y150-V4 about ten months ago. Honestly, the transition was smoother than I expected because our existing molds fit right in without any adjustment. The parting line issue we always had with the Japanese machine is completely gone now. Our cosmetic bottles look significantly cleaner and we have had zero complaints from our brand clients about surface quality since the switch. Energy bills are also noticeably lower month over month."

Rajesh Menon, Pharmaceutical Industry, India
"We run three Y150-V4 units for our PET pharmaceutical bottle line and they have been in continuous operation for over a year now. The GMP compliance was the main reason we went with the fully electric version (Y150-V4-EV) and it has passed every regulatory audit without a single issue. Daily output for our 50ml tablet bottles is consistently hitting 85,000 units across three cavities. CMN's engineers were on-site for two weeks during commissioning and trained our entire maintenance team thoroughly. Spare parts arrive within a week."

Mehmet Yilmaz, Beverage Industry, Turkey
"I was a bit skeptical about switching from a Japanese ISBM machine to a Chinese supplier but the price-to-performance ratio of the Y150-V4 is just hard to argue with. We run PET water bottles (500ml and 1,500ml) and the clarity of the bottles matches what we were getting from the ASB machine. What really surprised me is that CMN produces six cavities per cycle while the Japanese machine only did four. Our throughput increased by roughly 40% with the same two-shift schedule. Very happy with this decision."

Sergei Volkov, Personal Care Industry, Russia
"The Y150-V4 arrived well-packaged and the technical documentation was thorough. We produce shampoo and conditioner bottles in PETG and the machine handles the material processing temperature perfectly. Our previous machine had frequent heating ring failures but the nano far-infrared heating ring on the CMN screw has now been running over 11 months without a single replacement. Logistics from China to Russia took about 45 days by sea and everything arrived intact. Customer service responses are fast and helpful even with the time zone difference."

Thabo Dlamini, Chemical Industry, South Africa
"We are a small packaging company focused on agri-chemical bottles and the Y150-V4 has been a game-changer for our operation. The 150 KN injection clamping force handles our chemical-resistant PP resin without any short-shot issues even at higher injection speeds. CMN helped us select the correct 55mm screw diameter for our material viscosity profile. The machine footprint is small enough that we installed it inside our existing building without any structural modifications. Would definitely recommend CMN to other South African packaging businesses."

Carlos Ferreira, Beverage Packaging Industry, Brazil
"We bought the Y150-V4 for our beverage bottle line and we are very satisfied. Energy savings was our main reason for changing equipment, and the results confirmed the promise of a 25% reduction in electrical consumption. The machine was delivered within the agreed timeframe, and the installation videos provided by CMN were very detailed. Our team had no prior experience with ISBM equipment, yet we managed to be in production within three weeks."

Jennifer Walsh, Cosmetics Industry, United States
"We operate the Y150-V4 for high-end cosmetic packaging in Tritan resin. The machine's temperature control is precise enough to handle Tritan's narrow processing window without degradation or discoloration issues. In 14 months of continuous operation we have not had a single unplanned shutdown related to the machine itself. The Airtak cylinders on the take-out arm have been flawless. CMN's US technical representative provided excellent phone support when we had a question about adjusting the blow pressure profile for a new wide-neck jar format we introduced last quarter."

Alejandro Reyes, Food Packaging Industry, Mexico
"We bought two units of the Y150-V4 for our condiment bottle line producing 250ml PET sauce bottles in 4-cavity configuration. Output is stable at around 3,600 bottles per hour per machine and the dimensional consistency across cavities is excellent. We checked wall thickness on 50 consecutive cycles early on and the variation was within 0.08mm across all four cavities, which beat our specification. Delivery from CMN to Mexico by sea took 38 days. Installation and first production within a week of machine arrival on site."

Kim Dong-woo, Pharmaceutical Industry, South Korea
"After comparing three ISBM machine suppliers, we went with CMN primarily because of the ASB-12M mold compatibility. We had eight sets of ASB tooling already and replacing them would have been a large additional cost. The Y150-V4 accepted all eight mold sets and we were running production on all of them within two months of commissioning. The machine is noticeably quieter than our old hydraulic equipment and vibration levels on the factory floor are lower. Our operators also found the PLC interface much more intuitive to learn than the older Japanese HMI system."
