Chemical Foam Molding

Chemical Foam Molding is a process where the foaming gas is generated during the molding process. In the Chemical Foam Molding simulation, the reaction that generates the foaming gas is considered.

Chemical foam molding is supported for the following mesh types:

• 3D

Polyurethane (PU) foam molding is the most common example of chemical foam molding. Polyurethane foam production is a complex process involving reaction of water with isocyanate, which then forms carbamic acid. The acid then decomposes into carbon dioxide. PU foam molding is simliar to Thermoplastics microcellular injection molding, except that in PU foam molding:

• The foaming gas is generated in the cavity during molding
• The material is reactive
