Structural Foam Molding. Structural foam molding and sandwich molding both produce plastic parts that have an inner core that is foam surrounded by a dense outer skin, but only one produces a smooth part surface. Structural Foam Molding. In structural foam molding, the injection stage is basically the same, but the packing stage is augmented by a chemical blowing agent mixed with the material. The foaming action produces a sturdy honeycomb structure on the interior core which provides strength and superior impact resistance. Multiple molds can be run simultaneously A Lomont product that is molded using the structural foam process will typically have a surface which appears to have swirls on it. Dimensional Stability/Repeatability. Get a quick 1 minute answer here. Structural foam molding is a lower pressure process than injection molding, which results in low stress and warpage in the parts. Other advantages include less energy usage due to the low-pressure process and cost savings and sustainability from using less resin and less-expensive aluminum tooling. Orange, CA 92865.
