Co-injection is a polymer injection process in which different types of polymers are injected into the same mold, and the core material is completely encapsulated. The benefits of this process include:
- Reducing costs by using a cheaper fill material as the non-visible core of the product.
- Combining desired characteristics or mechanical properties of the polymers chosen such as colors, density, elasticity and so on.
- Reducing the energy usage due to a secondary plastic’s reduced melting point.
