Injection blow molding plays a vital role in modern industry, with applications ranging from everyday items to precision instruments. Choosing a high-quality manufacturer is crucial. We will recommend reliable injection blow molding manufacturers to help you find the most suitable partner among the many options.
II. Introduction to the Injection Blow Molding Process
1. Injection Molding:
1.1 Basic Principle: Granular or powdered plastic material is added to the hopper of the injection molding machine. It is heated to melt and flow. Then, driven by the machine's screw or piston, it enters the mold cavity through the nozzle and mold gating system, where it hardens and sets.
1.2 Process Flow: Raw Material Preparation → Injection Molding → Cooling and Curing → Demolding → Post-Processing.
1.3 Advantages:
High Precision: Capable of producing dimensionalally precise, complexly shaped plastic products with exceptional detail.
High Efficiency: Automated production is possible, with short cycle times, enabling rapid, high-volume production.
Strong material adaptability: Suitable for most thermoplastics, such as polyethylene, polypropylene, and polystyrene.
High strength: The product has a compact structure and high strength and hardness.
1.4 Scope of Application:
Electronic product casings: Such as mobile phone cases and computer cases, require high dimensional accuracy and appearance.
Automotive parts: Such as dashboards and bumpers, require high strength and good wear resistance.
Household plastic products: Such as plastic tableware and toys, are produced in large quantities and have a variety of shapes.
2. Blow Molding:
2.1 Basic Principle: A thermoplastic resin or tubular plastic blank is placed into a mold. After the mold is closed, compressed air is injected into the mold to inflate the plastic blank and close to the mold wall. The desired hollow product is then produced by cooling and demolding.
2.2 Process Flow: Raw material preparation → Extrusion of the parison → Blow molding → Cooling and curing → Demolding → Post-processing
2.3 Advantages:
Low cost: The mold is relatively simple, resulting in low production costs.
Suitable for hollow products: Hollow containers of various shapes, such as bottles and cans, can be produced.
Lightweight: Products are lightweight, making them easy to transport and use.
Impact Resistance: The hollow structure provides excellent impact resistance.
2.4 Scope of Application:
Packaging Industry: Widely used for packaging containers for food, beverages, cosmetics, etc.
Chemical Containers: Such as storage barrels and oil tanks require excellent sealing and corrosion resistance.
Sports Equipment: Such as swimming rings and floating boards require lightweight and safe operation.
