Structral Foam Molding

Structral Foam Molding

Structural foam molding is a low-pressure method of processing thermoplatics. Inert gas, usually nitrogen, inserted into the resin causes bubbles to form and create a foaming action that helps fill a molding cavity. Gases created by decomposition of a chemical blowing agent is another way foaming occurs in this process. The process creates rigid parts with hard surfaces.
