This article introduces five common types of plastic moulding processes systematically, elaborates on the advantages of injection molding, and focuses on the features and application scenarios of high precision plastic injection molding and services by low volume injection molding companies, providing practical guidance for selecting the best plastic moulding solutions on Vanmodel.

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.

Vanmodel is an injection mold inc focused on high precision plastic injection molding services, providing comprehensive mold design, manufacturing, and molding production one-stop solutions.

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.
