What is Injection Molding?

Topgrid Injection Molding Service
  • Injection molding is a manufacturing technique used to create parts and products by injecting molten material into a mold cavity.
  • The material, typically thermoplastic or thermosetting plastic, is forced into the mold under high pressure and temperature conditions.
  • After cooling and solidifying inside the mold, the final product is removed, ready for use.

Injection Molding Process

Understanding the injection molding process is crucial to grasp the intricacies of this manufacturing method. Here are the key steps involved:

Material Preparation:

The process starts with selecting the appropriate material. Common choices include polyethylene, polypropylene, and ABS due to their ability to be melted and reshaped repeatedly. These materials are usually provided in the form of pellets or granules and are loaded into the injection molding machine.


The selected material is heated within the machine’s barrel until it reaches a molten state. Precise temperature and pressure control are essential to achieve the optimal material condition for injection.


Once the material is molten, it is injected into the mold cavity through a runner system. The mold cavity is designed to replicate the desired part or product’s shape.


As the molten material fills the mold cavity, it begins to cool and solidify. Cooling is a critical phase that affects the product’s final quality and structure. Mold cooling can be expedited using cooling channels integrated into the mold.


After adequate cooling and solidification, the mold opens, and the finished product is ejected. Ejection pins, plates, or other mechanisms are employed to remove the product from the mold.

Post Processing:

In some cases, additional post-processing steps like trimming, painting, or assembly may be necessary to meet specific product requirements.
