Co-injection involves the injection of two different materials using the same injection location. Bi-injection is the injection of two different materials at separate injection locations, with independent process controls.

Setting up a Co-injection analysis
The following table summarizes the setup tasks required to prepare a Co-injection analysis of a non fiber-filled, or fiber-filled thermoplastic material.
Material to inject (A/B) dialog
The Set Material to inject (A/B) dialog is used to specify whether material A or material B is injected at the selected injection location for a Co-injection or Bi-injection molding process.
Co-injection analysis
Co-injection molding involves the injection of two different materials into the one mold.
Bi-injection molding process overview
A bi-injection molding process involves injection of two different materials into a mold at separate injection locations, which are controlled independently by two different injection units.
