types of plastic moulding process

Main categories of types of plastic moulding

injection molding

injection molding involves injecting molten plastic into a closed mold cavity under high pressure, cooling, and forming into the desired shape. It is characterized by high efficiency, high precision, and is suitable for mass production of complex parts.

compression molding

compression molding preheats plastic material, places it into an open mold cavity, and then applies high pressure and temperature to solidify it into shape. It is commonly used for thermosetting materials and large composite components.

extrusion molding

extrusion molding continuously extrudes molten plastic through a shaped die, ideal for producing pipes, sheets, and films.

blow molding

blow molding places a heated plastic parison into a mold and inflates it to form a hollow part. It is widely used for bottles and container products.

rotational molding

rotational molding loads powdered or granular plastic into a mold, which is then heated and rotated to evenly distribute the material on the mold surface. Suitable for large hollow plastic products like water tanks and animal models.

Analysis of advantages of injection molding

The advantages of injection molding mainly include:

• High efficiency: Short cycle time per molding, ideal for mass production.

• Complex structures: Capable of producing thin-wall, hollow structures, and embedded circuits.

• High consistency: Control over temperature, pressure, and injection speed ensures dimensional tolerances meet US or EU standards.

• Material versatility: Supports various engineering plastics and high-performance materials compliant with RoHS certificates.

Leveraging the advantages of injection molding, JSJM helps you optimize your cost, quality, and efficiency comprehensively.
