Common Injection Molding Processes

Injection molding is a plastic processing technology widely used in the manufacturing industry, and common types of injection molding include the following: Conventional injection molding: Conventional injection molding refers to the heating and melting of plastic materials into the mold, cooling to obtain a variety of different shapes of plastic products. Conventional injection molding is suitable for the production of various specifications, shapes and materials of plastic products, such as plastic tableware, home appliance shell and so on. Two-color injection molding: Two-color injection molding refers to the injection molding of two different colors or materials of plastic materials in the same mold, so as to form different colors or materials on the same product. Two-color injection molding is suitable for the production of complex plastic products requiring multi-color or multi-material combinations, such as automotive interiors. High-speed injection molding: High-speed injection molding refers to the use of high-speed injection, high-pressure injection and other technologies in the injection process, so as to achieve rapid production of plastic products. High-speed injection molding is suitable for the production of large volume, simple structure of plastic products, such as bottle caps. Precision injection molding: Precision injection molding refers to the use of high-precision molds and high-precision injection machines in the injection process, so as to achieve high-precision, high-quality plastic products production. Precision injection molding is suitable for the production of precision, complex, high-quality plastic products, such as mobile phone shells, optical lenses, etc. Pneumatic injection molding: Pneumatic injection molding refers to the use of air pressure to drive plastic materials into the mold during the injection process, so as to achieve efficient and high-quality plastic product production. Pneumatic injection molding is suitable for the production of high-volume, thin-wall, high-transparency plastic products, such as plastic cups, plastic glass and so on.

Large injection molding: Large injection molding refers to the production of large size, large weight and large volume plastic products through large injection molding machines and large molds, such as auto parts and engineering plastic products. Thin-wall injection molding: Thin-wall injection molding refers to the production of thin-wall plastic products with wall thickness below 0.5mm through high-speed injection molding and high-precision molds, such as plastic containers, boxes, etc. Micro-injection molding: Micro-injection molding refers to the production of micro-size plastic products through micro-injection molding machines and micro-molds, such as micro-parts, micro-devices, etc. Composite injection molding: Composite injection molding refers to the injection of plastic materials of different materials into the same mold, thereby forming plastic products of composite materials, such as plastic metal composite products, plastic rubber composite products, etc. Hot runner injection molding: Hot runner injection molding refers to the setting of heating elements in the mold, by controlling the temperature and position of the heating elements, to achieve the precise control of plastic materials into the mold, so as to produce high-quality, high-precision plastic products. Injection molding is a very flexible and efficient plastic processing technology that is suitable for the production of a wide variety of plastic products. With the continuous progress of technology and the constant change of market demand, injection molding technology is also constantly developing and innovating, and the types and application fields of injection molding are also constantly expanding and deepening.
