Our Injection Stretch Blow Molding Machine 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.

Characteristics of the Y250-V4-B Injection Stretch Blow Molding Machine

The Y250-V4-B one step injection stretch blow molding machine exhibits a range of technical characteristics that set it apart in the field of ISBM equipment. At its core, the machine utilizes a 4-station rotary design, enabling simultaneous processing of multiple preforms and finished products for high throughput. The injection system features a high-precision servo-driven screw (50-60 mm diameter options) with theoretical injection volumes ranging from 315 to 480 cm³, allowing flexibility across different bottle sizes and weights. High-pressure Parker valves and imported air cylinders ensure stable and repeatable clamping forces of 300 kN for injection and 250 kN for blowing, minimizing flash and ensuring uniform wall thickness.

Temperature control is achieved through an integrated box with high-accuracy sensors (±1°C precision), supporting zoned heating for optimal preform conditioning without over-heating the neck area. The turntable is driven by Yaskawa or equivalent servo motors with Taiwan reducers for smooth, precise rotation, while the blow molding structure incorporates dual-servo or hydraulic options with high-pressure compensation for consistent radial stretching. Lead screws from NSK Japan and nano far-infrared heating rings contribute to energy efficiency and long service life. The machine's total power consumption is optimized at approximately 82.7 kW, reflecting its focus on low energy use.

Additional characteristics include robust construction with an oil tank capacity of 300-600 L (model dependent), Italian-imported tubing for hydraulic reliability, and compatibility with multi-cavity molds for high-output production (8-28 cavities depending on bottle dimensions). The take-out stroke and mold strokes are calibrated for rapid cycle times (typically 10-30 seconds), supporting annual outputs in the millions of units.

One Step Injection Stretch Blow Molding Advantages

1. Integrated Production That Eliminates Handling Risks
The one step injection stretch blow molding process brings every stage—from preform injection to finished bottle ejection—together inside a single compact machine. No more moving hot preforms between separate units by hand or conveyor, which often leads to scratches, dust pickup, or shape distortion. Factories running daily shifts report far fewer contamination complaints, especially when producing food-grade or pharmaceutical bottles. The closed-loop system keeps everything clean and controlled, giving operators peace of mind and delivering containers that meet the strictest hygiene standards straight off the line.

2. High Automation That Boosts Output and Cuts Costs
With full servo control and a 10-to-30-second cycle, the one step injection stretch blow molding machine keeps four stations working at once instead of sitting idle like older two-step lines. One operator can easily manage what used to need three or four people. Customers regularly see annual outputs exceeding one million bottles per machine while slashing labor and energy bills. The smooth, predictable rhythm means fewer stops, quicker changeovers, and steady production even during peak seasons for cosmetics or beverage packaging.

3. Stable Quality and Noticeably Better Bottle Performance
Precise stretch ratios and blow pressures in the one step process create wall thickness that stays within ±5% across every bottle—something two-step methods rarely achieve without extra tuning. Tensile strength jumps more than 30%, transparency looks crystal clear, and the surface feels smoother to the touch. Production teams mention fewer rejects and stronger bottles that survive shipping and stacking better. Whether making slim mascara tubes or wide-mouth jars, the final product consistently passes quality checks the first time.

4. High Material Efficiency and Real Energy Savings
By using the residual heat from injection directly for blowing, the one step injection stretch blow moulding technology skips the big reheating ovens that eat up 20–30% extra power in traditional setups. Scrap drops dramatically and goes straight back into the hopper, pushing material utilization above 95%. Plant managers often share that their monthly electricity and resin bills drop noticeably after switching, while the smaller footprint frees up valuable factory floor space for more machines or storage. It’s a practical win for both the environment and the bottom line.

One-Step Injection Stretch Blow Molding Machine Working Process

The Y250-V4-B one step injection stretch blow molding machine follows a synchronized four-station rotary process that turns raw plastic pellets straight into finished containers in a single continuous cycle. This integrated single-stage approach eliminates separate preform storage and reheating steps, giving operators tight control over temperature, stretch ratios, and cooling to produce containers with excellent wall-thickness uniformity and strong mechanical performance.

Station 1: Injection Molding (Preform Creation)
Plasticizing and injection start when PET or PETG granules enter the high-precision screw and barrel system, where they are melted under carefully managed heat and shear forces to reach a uniform, bubble-free molten state. The melt is then injected at high speed and pressure into the closed preform mold surrounding the core rod, allowing exact control of initial wall thickness distribution and gate area. This step sets the foundation for later stretching by establishing consistent crystallinity levels through optimized mold cooling, ensuring the preform is ready for uniform deformation without defects.

Station 2: Temperature Conditioning and Tail Trimming
After the rotary table indexes the still-hot preform to the second station, a servo-driven trimming unit precisely removes the injection gate from the base, leaving a clean, flat surface that will not affect container strength or appearance. The preform then enters a multi-zone conditioning oven where heating coils apply differential temperatures: the body is reheated to the ideal stretching range while the neck area stays cooler to protect thread geometry and prevent softening. This zoned reheating ensures the material reaches exactly the right thermal profile for controlled biaxial orientation during the next stage.

Station 3: Stretch Blow Molding (Forming)
At the third station the blow mold closes securely around the conditioned preform. A servo-controlled stretch rod then descends through the neck, mechanically extending the material axially at high speed and precise positioning to align polymer chains in the longitudinal direction. At the same moment, high-pressure air (2.0–3.5 MPa) is introduced through the blow core, inflating the preform radially until it presses firmly against every contour of the mold cavity. The combined axial and radial stretching creates strong molecular orientation in both directions, delivering containers with superior clarity, barrier properties, impact resistance, and top-load strength.

Station 4: Cooling and Product Removal
Once blowing is complete, cooling water circulates rapidly through the optimized channels in the mold walls, extracting heat from the formed container within 5 to 20 seconds depending on wall thickness and material type. This controlled cooling locks in the final shape and minimizes shrinkage or warpage. When the container reaches the required temperature for safe handling, the mold opens and a gentle ejection system removes the finished product onto the takeaway conveyor, ready for downstream leak testing, labeling, and packing. The entire four-station sequence repeats automatically, delivering consistent high-quality output with minimal operator intervention.

Composition of One-Step Injection Blow Molding Equipment

1. Injection Molding System
The injection molding system forms the foundation of the machine, using a high-precision servo-driven injection unit paired with a dedicated screw and barrel assembly tailored for PET and PETG materials. In the Y250-V4-B model, this system delivers uniform plasticization with temperature control accuracy held to within ±1°C across multiple barrel zones, preventing material degradation and ensuring consistent melt viscosity every cycle. The servo injection mechanism offers fast response times and outstanding repeatability, while the advanced preform wall thickness control allows fine axial and radial adjustments during filling.

2. Heating System
The heating system prepares each preform for perfect stretching by applying controlled, differential temperatures exactly where needed. It combines multiple zoned heating coils with water or oil circulation circuits and real-time temperature sensors that monitor conditions continuously. Operators can heat the body area to the ideal stretching range while keeping the neck region cooler to protect thread geometry and maintain dimensional accuracy. Non-contact measurement methods avoid any surface marks or damage on the preform, and the adaptive power adjustment automatically optimizes energy input according to current production speed.

3. Stretch Blow Molding System
The stretch blow molding system performs the critical transformation from conditioned preform to finished container through precise axial and radial stretching. It features a high-speed servo stretch rod capable of reaching 400 mm/s with positional accuracy of ±0.1 mm, paired with a precision blow core and a stable high-pressure air delivery system. An independent pressure regulating valve keeps blowing pressure fluctuations tightly controlled within ±0.05 MPa, delivering repeatable results across thousands of cycles. Synchronous control technology coordinates the stretch rod movement and air injection perfectly, creating strong molecular alignment in both longitudinal and transverse directions.

4. Mould System
The mould system consists of preform moulds, blow moulds, and an advanced cooling network arranged in a reliable four-station rotary configuration that allows simultaneous processing at each stage. High-precision machining produces cavity surfaces with roughness as low as Ra ≤ 0.8 μm, giving containers a smooth, premium appearance straight from the mould. Optimized cooling channel design shortens cooling time by up to 30%, enabling faster cycle speeds without compromising shape stability. This robust multi-station setup delivers both high output and the versatility needed to run round, oval, or custom-shaped containers across a wide range of capacities.

5. Control System
The control system acts as the intelligent brain that synchronizes all five systems for smooth, repeatable operation. It uses a sophisticated multi-axis motion controller to coordinate every movement across the four stations with high accuracy, while adaptive algorithms continuously adjust key process parameters based on live production data. Built-in remote monitoring and comprehensive fault diagnosis tools allow quick identification and resolution of any issues before they affect output. The user-friendly interface stores multiple recipes for different bottle designs, enabling fast product switches with minimal trial runs.
