Structural Foam
The cross-sectional view of a molded structural foam part reveals a solid plastic outer skin enclosing a plastic foam core. To create that core, we introduce inert gas right into the resin melt. Or, a chemical "blowing agent" is pre-blended with the resin prior to heating. In either case, the mixture is shot into a mold and allowed to expand under relatively low pressure. That results in a low-stress part and a more pleasing appearance. At FM Corporation, we mold parts with shot weights ranging from 1 oz. to 150 lb. With over 40 molding stations, our production is both reliable and cost-efficient.

Structural foam benefits

Stiffness-to-weight: Structural foam offers a significant advantage over equivalent weights of other materials, including metal and injection-molded plastics.
Manufacturing efficiency: Ribs, bosses, snaps, hinges and other features can be molded-in for significant cost savings.
Longer tool life: Lower cavity pressure and slower injection speed with greatly reduced wear and tear on molds.
Sound dampening characteristics: Use structural foam parts to reduce overall noise output.
Improved appearance: The low-pressure structural foam process results in fewer "sink marks."
Mechanical Properties - Less molded in stress leaves more mechanical strength for function.
