Structural foam molding is a low pressure injection molding process that is capable of producing very large structural parts. The molten plastic is injected into a mold after being mixed with a blowing agent, causing the plastic to “foam.” The structural foam injection molding process is well suited for large plastic parts because the foaming gas bubbles in the resin matrix pack out the resin and reduce the incidence of sink on the show side of the plastic part. Structural foam molding parts are usually very thick, nearly 0.250” wall thickness, and are ideal for plastic structural elements that will not be in view. Parts which are in view require sanding, painting, and finishing.

Structural Foam is produced by mixing raw resin with a chemical blowing agent which “foams” after the mixture is introduced in an injection mold. This foaming produces very small gas bubbles which are evenly distributed throughout the resin matrix (see structural foam cross section below-left). These gas bubbles impart a marbled or swirled surface finish on the part. One way to combat the marbled appearance and swirls in the surface finish, shown above, is by employing gas counter pressure with structural foam. In this process, the mold is pressurized with gas at a pressure higher than that of the foaming gas prior to the resin’s introduction in the mold (see structural foam w/gas counter pressure diagram below). When performed correctly, a smoother, glossier, and more consistent surface finish is produced.
