Thermosets, also known as thermosetting plastics, were the first polymer materials to be molded on a widespread basis. However, modern material technology and processing techniques have made thermoset molding far from obsolete. Thermosets offer a light weight, cost effective option when designing metal replacements. Their heat tolerance and stability make thermoset plastics ideal for electrical or automotive underhood enclosures.
Parkway Products has over 50 years of thermoset molding expertiese, and can assist in the design, material selection and mold making processes to ensure consistent, quality results. Parkway EMP houses a full portfolio of thermoset molding capabilites, including injection molding, compression molding, transfer molding, insert molding, and a host of in-house secondary operations, including machining, drilling, tapping and deflashing.
Thermoset Injection Molding
Thermoset injection molding is similar in process to standard plastic injection molding. Thermoset injection offers the lowest processing time with the lowest amount of flash. It also offers the ability to mold the most intricate, precision parts out of thermoset materials.
Thermoset compression molding allows the maximum capabilites of the material to show through in finished parts. Its process allows the longest fiber length and is ideal for larger sized, structural parts.
Transfer molding bridges the gap between the capabilities of injection and compression molding. Transfer molding allows for longer fiber lengths than in injection molding, but with more precision and less flash than compression molding.
