One-step Injection stretch blow moulding is a highly efficient plastic container molding process widely used in the production of high-precision, high-demand hollow plastic products (e.g. baby bottle, water bottle, medicine bottle, craft and special-shaped bottle, cosmetic bottle made of PET, PETG, PP, PC, Tritan, PS, ABS or PLA etc.). Its core feature is that the three steps of injection, stretching and blow moulding are completed continuously in the same equipment without intermediate steps, which greatly improves production efficiency and product stability.
High efficiency and energy saving: No secondary heating of the preform is required; blow molding is performed directly using the preform temperature, reducing energy consumption by approximately 40%.
Superior performance: Stretching causes the material molecules to stretch in a specific direction, significantly improving the product's compressive strength, barrier properties, and transparency.
High dimensional accuracy and good stability: Fully automated control reduces human error, suitable for large-scale production.
High material utilization: Less waste, environmentally friendly, and low cost.
Equipment advantages: Low energy consumption, low labor costs, small footprint, and strong product stability.
Equipment composition and key technologies: The one-step injection stretch blow molding equipment mainly consists of five parts: injection system, heating system, stretch blow molding system, mold system, and control system. The key technologies of each system are as follows:
1. Injection system: The injection system adopts a high-precision servo-driven injection unit, equipped with a dedicated screw and barrel, ensuring uniform plasticization of the plastic melt. Key technologies include:
High-precision temperature control system (temperature control accuracy ±1ºC)
Servo-driven injection unit (fast response speed, high repeatability)
Preform wall thickness control system (optimizes wall thickness through axial or radial adjustment)
2. Heating System The heating system uses heating coils or water-oil heating methods, equipped with temperature sensors to monitor the temperature in real time. Key technologies include:
Zoned heating control (achieving precise temperature control of different parts of the preform)
Non-contact temperature measurement (avoiding damage to the preform surface)
Adaptive heating power adjustment (automatically optimizing heating parameters according to production speed)
3. Stretch Blow Molding System The stretch blow molding system consists of a stretching rod, blow core, and high-pressure air source, realizing the axial stretching and radial expansion of the preform. Key technologies include:
Stretching mechanism (stretching speed up to 400mm/s, positioning accuracy ±0.1mm)
High-pressure gas uses an independent pressure regulating valve system (pressure fluctuation controlled within ±0.05MPa)
Stretch-blow molding synchronous control technology (ensuring precise coordination of stretching and blow molding processes)
4. Mold System The mold system includes preforming molds, blow molding molds, and a cooling system, typically employing a rotary multi-station structure (3-4 stations). Key technologies include:
High-precision mold processing technology (cavity surface roughness Ra≤0.8μm)
High-efficiency cooling system (optimized cooling channel design, reducing cooling time by 30%)
Quick mold change technology (mold change time ≤60 minutes)
5. Control System An independent control system is used to achieve centralized control and parameter optimization of the entire production process. Key technologies include:
Multi-axis motion control system (achieving precise synchronization of each station)
Adaptive optimization of process parameters (adjusting process parameters in real time based on production data)
Remote monitoring and fault diagnosis system (improving equipment operational stability)
Bottles and Containers: It is primarily used for making a variety of plastic bottles, such as beverage bottles, cosmetic containers, pharmaceutical packaging, and household product packaging. The one-step process ensures high-quality, precise, and uniform bottles.
Cosmetic Packaging: The machine is used to produce sleek, attractive containers for cosmetic products such as shampoos, lotions, and perfumes. The high level of precision allows for the creation of intricate designs.
Pharmaceutical Packaging: The one-step blow molding machine is utilized in the production of medical and pharmaceutical packaging, ensuring safety and hygiene in the manufacturing process. This includes making bottles for liquid medicines, eye drops, and more.
Food and Beverage Industry: It is a common tool in the production of PET bottles for soft drinks, water, and other beverages. The one-step process ensures that the bottles are free of contamination and meet regulatory standards.
Small Volume, Custom Designs: Because of the flexibility in design and rapid production, one-step blow molding is ideal for creating smaller batches of bottles with unique shapes or customized features, catering to niche markets.Production Process

Q:What is a one-step blow molding machine, and how does it work?
A:A one-step blow molding machine combines both injection molding and blow molding processes into a single production step. It starts by injecting molten plastic into a mold to create a preform, then immediately blows air into the preform to form it into a bottle or container shape. This integrated approach minimizes the need for separate machines, leading to faster production cycles and improved efficiency.
Q:What types of materials can be used with a one-step blow molding machine?
A:The most commonly used materials for one-step blow molding are PET (Polyethylene Terephthalate), PP (Polypropylene), and PE (Polyethylene). These materials are popular for producing bottles, containers, and other plastic packaging. Some machines can also process other thermoplastics, depending on the design and specifications of the machine.
