What Is Structural Foam Molding Process?

Structural foam molding is a widely used low pressure injection molding process. In this process, the plastic is melted and then is foamed with a chemical blowing agent or nitrogen gas. As the plastic fills the specific mold, the wall solidifies against the cold wall of the mold – solidifying a thin layer of plastic along the mold wall. This thin layer then forms a sort of skin structure over the foamed inner core. The solid thin outer wall is rightly supported by the interior cellular foam structure.

There are many benefits of using structural foam molding process. It is widely used for manufacturing different sized parts ranging from huge ones to small. The parts produced are stronger and are potentially longer lasting part. For several larger parts, thicker walls are required that standard injection molding can’t produce efficiently. This process allows for the injection molding of such parts by the addition of a foaming agent. Additionally, in this process, any sort of injection moldable plastic can be used to manufacture the parts. The greatest advantages of structural foam molding process for manufacturers is that multiple parts can be simultaneously molded on the same machine cycle – consequently saving time and expenses.
