Injection

What is Injection in Injection Molding?

Injection in injection molding refers to the process of injecting molten material, typically plastic, into a mold cavity to produce a desired part or product. This process is a fundamental step in injection molding, which is a widely used manufacturing method for producing plastic components with high precision and efficiency.

The injection process involves several key steps:

  1. Melting the Material: Plastic pellets or granules are heated until they reach a molten state suitable for injection.
  2. Injection: The molten material is injected into the mold cavity under high pressure, filling the cavity and taking the shape of the mold.
  3. Cooling: Once the mold cavity is filled, the material is allowed to cool and solidify within the mold, taking on the desired shape.
  4. Ejection: After the material has solidified, the mold opens, and the newly formed part is ejected from the mold cavity.

The injection process is highly precise and repeatable, allowing for the production of complex parts with tight tolerances. It is widely used in various industries for manufacturing a wide range of products, from small components to large automotive parts.
