Chemical Blowing Agent for Microcellular Injection Molding

A new microcellular injection molding feature, the simulation of a Chemical Blowing Agent (CBA), has been added.

This feature is supported for the following mesh types:

and makes the following assumptions:

When using a chemical blowing agent to generate the foaming gas, the chemical blowing agent is premixed with the polymer in the pellet. The chemical reaction occurs in the barrel, typically upon heating, to generate a foaming gas. Mixture in the barrel is then injected into the cavity. An advantage of this process is that you can use a regular injection molding machine, without modification.

To simulate microcellular injection molding using a chemical blowing agent, select Chemical blowing agent (CBA) in the process settings.

Once you have selected a chemical blowing agent, edit the value associated with the chemical blowing agent in the Initial gas amount dialog.
