Structural foam molded pallet

By MHI

Structural foam molding is a variation of the injection molded process whereby a compounded plastic material is introduced into an extruder in pellet form, heated to a molten state, and then formed by means of a rotating screw into one or more mold cavities. The material adopts the configuration of the mold, and once cooled, it is injected as a fully formed pallet.
With structural foam molding, a blowing agent is introduced to and mixed thoroughly through the plastic prior to its injection into the mold cavities. The heating process activates the blowing agent and creates a cellular structure within the molten material.
This cellular structure not only saves on raw material requirement, but it produces a part with an elevated strength-to-weight ratio.
