If your heavy wall sectioned part requires a more cosmetic surface Imperial Plastics offers Multi-Nozzle structural web molding. This process is similar to multi-nozzle structural foam molding except nitrogen is not introduced during the melting process. Instead, melted plastic is shot into the mold and gas is subsequently injected to pack out the part. This produces a part with a solid skin with hollow cross sections. This process typically requires additional tonnage (larger press) versus traditional multi-nozzle structural foam.
Our engineers can assist your design team to develop a component incorporating proper web channel geometry. Key benefits include; greatly improved surface finish on large parts often reducing the need for painting, part weight reduction, and sink elimination.
