PET bottle molding machines transform raw PET resin into durable, lightweight bottles through a two-step process: injection molding (creating preforms) and blow molding (stretching preforms into bottles). These machines are pivotal in meeting high-volume production needs while ensuring consistency and compliance with safety standards.
How Does PET Bottle Molding Machine Work？
Heating: Preforms are heated to 90–110°C for plasticity.
Stretch Blow Molding: A stretch rod elongates the preform vertically, while compressed air (25–40 bar) expands it radially into the mold cavity.
Final Cooling: Bottles cool within the mold to stabilize dimensions.
Key Points:
Clamping Unit: Secures molds during injection/blowing.
Hydraulic/Pneumatic System: Powers machine operations.
Control Panel: Enables parameter adjustments (temperature, pressure, cycle time).
Applications of the Blowed PET Bottles
Beverages: Carbonated drinks, water, and juices.
Pharmaceuticals: Sterile containers for syrups and tablets.
Cosmetics: Elegant bottles for lotions and shampoos.
Household Products: Detergent and cleaning solution containers.
Advantages of PET Bottle Blowing Machine
1. Efficient production: pet bottle molding machine can produce a large number of bottles quickly and efficiently.
2. Customizable designs: These machines allow for a wide range of bottle shapes and sizes to be produced.
3. Cost-effective: With low operating costs and high production rates, pet bottle molding machines can be a cost-effective solution for companies looking to produce PET bottles.
4. Reduced waste: By producing bottles on demand, there is less risk of excess inventory or wasted materials.
5. Easy maintenance: These machines are designed for easy maintenance and are built to last, providing a reliable production system.
