What is injection molding?

Last updated on Mar 20, 2023

Injection molding is a manufacturing process used to create plastic parts in large quantities. Molten plastic material is injected into a mold or cavity, which is then cooled and solidifies into the desired shape. The process involves feeding plastic pellets into a hopper, which are then heated to a molten state and injected into the mold under high pressure. This pressure ensures that the material fills the mold completely and uniformly, resulting in a high-quality finished product. Injection molding is commonly used to create products such as toys, automobile parts, packaging materials, and medical devices.
