4. Equipment Composition and Key Technologies of injection stretch blow moulding machine<\/h2>\n

The one-step injection stretch blow molding equipment mainly consists of five parts: injection molding system, heating system, stretch blow molding system, mold system, and control system. The key technologies of each system are as follows:<\/p>\n

1. Injection Molding System<\/strong><\/h3>\n

The injection molding system adopts a high-precision servo-driven injection unit, equipped with a dedicated screw and barrel to ensure uniform plasticization of the plastic melt. Key technologies include:<\/p>\n

1.1. High-precision temperature control system (temperature control accuracy \u00b11\u2103)<\/p>\n

1.2. Servo-driven injection unit (fast response speed, high repeatability)<\/p>\n

1.3. Preform wall thickness control system (wall thickness optimization through axial or radial adjustment)<\/p>\n

2. Heating System<\/strong><\/h3>\n

The heating system adopts heating coils or water and oil heating methods, equipped with temperature sensors to monitor the temperature in real time. Key technologies include:<\/p>\n

2.1. Zoned heating control (achieving precise temperature control of different parts of the preform)<\/p>\n

2.2. Non-contact temperature measurement (avoiding damage to the preform surface)<\/p>\n

2.3. Adaptive heating power adjustment (automatically optimizing heating parameters according to production speed)<\/p>\n

3. Stretch Blow Molding System<\/strong><\/h3>\n

The stretch blow molding system consists of a stretching rod, blow core, and high-pressure gas source, achieving axial stretching and radial inflation of the preform. Key technologies include:<\/p>\n

3.1. Stretching mechanism (stretching speed up to 400mm\/s, positional accuracy \u00b10.1mm)<\/p>\n

3.2. High-pressure gas with an independent pressure regulating valve stabilization system (pressure fluctuation controlled within \u00b10.05MPa)<\/p>\n

3.3. Stretch-blow molding synchronous control technology (ensuring precise coordination between the stretching and blow molding processes)<\/p>\n

4. Mold System<\/strong><\/h3>\n

The mold system includes the preform mold, blow molding mold, and cooling system, typically employing a rotary multi-station structure (3-4 stations). Key technologies include:<\/p>\n

4.1. High-precision mold processing technology (cavity surface roughness Ra\u22640.8\u03bcm)<\/p>\n

4.2. High-efficiency cooling system (optimized cooling channel design, reducing cooling time by 30%)<\/p>\n

4.3. Quick mold change technology (mold change time \u226460 minutes)<\/p>\n

5. Control System<\/strong><\/h3>\n

An independent control system is adopted to achieve centralized control and parameter optimization of the entire production process. Key technologies include:<\/p>\n

5.1. Multi-axis motion control system (achieving precise synchronization of each workstation)<\/p>\n

5.2. Adaptive optimization of process parameters (adjusting process parameters in real time based on production data)<\/p>\n

5.3. Remote monitoring and fault diagnosis system (improving equipment operational stability)<\/p><\/blockquote>\n

5. The difference between 4-station and 3-station injection stretch blow molding machines<\/h2>\n

The primary difference between 4-station and 3-station injection stretch blow molding machines lies in the number of processing steps and stations involved in the production cycle.<\/p>\n

1. 4-Station Machines:<\/strong><\/h3>\n

The 4-station process adds an additional station dedicated to temperature regulation and pre-blowing (after the injection molding). This improves uniformity in wall thickness and overall product quality by ensuring the preform is at the ideal temperature before stretching and blowing.
\nThis extra step increases flexibility and efficiency, especially for more complex containers that require precise thermal conditions.<\/p>\n

2. 3-Station Machines:<\/strong><\/h3>\n

The 3-station machines typically combine the heating, pre-blowing, and stretching\/blowing processes into fewer stages. This reduces the complexity of the system and may be suitable for simpler, less complex bottle designs where exact temperature control and pre-blowing are not critical.
\nThe process is quicker but may have less control over wall thickness uniformity compared to the 4-station system.<\/p>\n

In essence, 4-station systems provide better quality control and efficiency, making them ideal for more demanding applications, while 3-station systems are more suitable for high-speed, simpler production requirements.<\/p><\/blockquote>\n

6. Injection stretch blow molding machine: Material Versatility & Global Standards<\/h2>\n

Material flexibility is a hallmark of the injection stretch blow molding products generated by our V4 series. The system is optimized for PET (Polyethylene Terephthalate), known for its recyclability and transparency, but it also excels with PETG, which offers enhanced toughness for high-end luxury packaging. For the Colombian food industry, the machine efficiently processes PP (Polypropylene), providing heat-resistant containers for hot-fill applications. Advanced engineering plastics like PC and Tritan (BPA-free) are also supported, enabling the production of reusable sports bottles and high-clarity baby feeding bottles. By utilizing premium alloys for our injection stretch blow mold components, we ensure a long service life and resistance to thermal fatigue, meeting international hygiene standards for food-grade contact materials.<\/p>\n

8. Field Notes: Engineer Perspectives<\/h2>\n
\n

“We recently installed the EP-BPET-94-V3 in our Bogota facility for a high-volume medicine bottle project. The precision of the 3-station system is outstanding. We were previously using expensive Japanese injection stretch blow molding machines<\/strong>, but this unit provides the same neck tolerance and body clarity at a much better value. The technical team assisted with the mold commissioning perfectly.”<\/p>\n

– Lead Production Engineer, Pharmaceutical Group (Colombia)<\/strong><\/p>\n<\/div>\n

“Operating in Medellin requires equipment that can handle fluctuating power and humidity. The servo-driven injection stretch blow molding machine<\/strong> from EVER-POWER has been extremely stable. We produce Tritan baby bottles, and the clarity is indistinguishable from European brands. The one-step process has reduced our scrap rate by 12%.”<\/p>\n
