Plastic parts plastic molding the most common injection molding injection molding process
Injection molding: also known as injection molding, its principle is to add granular or powdery raw materials to the hopper of the injection machine, the raw materials are heated and melted in a flowing state, driven by the screw or piston of the injection machine, through the nozzle and the mold pouring system into the mold cavity, hardening and shaping in the mold cavity. Factors affecting the quality of injection molding: injection pressure, injection time, injection temperature.
Process features:
Advantages:
1, molding cycle is short, high production efficiency, easy to realize automation
2, can form complex shape, precise size, with metal or non-metal inserts of plastic parts
3. Product quality is stable
4. Wide range of adaptation
Disadvantages:
1. The price of injection molding equipment is high
2. The structure of the injection mold is complex
3, high production cost, long production cycle, not suitable for single small batch of plastic parts production
Application:
In industrial products, injection molding products are: kitchen supplies (garbage cans, bowls, buckets, kettles, tableware and various containers), electrical equipment shell (hair dryer, vacuum cleaner, food mixer, etc.), toys and games, various products in the automobile industry, and parts for many other products.
