Process
The manufacturing process is complex, requiring both technical expertise and specialized custom equipment. Polypropylene resin is combined with other ingredients in a multi-step proprietary process. Under tightly controlled conditions, extruded pellets expand to become consistently shaped beads of expanded polypropylene foam. Other specialized manufacturing techniques may be employed to produce variations in the final product form.
EPP foam beads are then injected into molds. In many cases, cost-effective multi-cavity aluminum molds are used. Pressure and steam heat fuse the beads into a finished shape. The finished EPP foam part becomes a key component in sub-assemblies incorporated in the original equipment manufacturer’s product.
