Thermoset Molding

Southwest Plastics, located in Southern California, has the experience required to obtain optimal results for our customers' thermoset components.

Heat-resistent thermoset plastic parts can be manufactured through thermoset transfer molding, thermoset compression molding and thermoset injection molding. Thermoset plastic parts made from thermoset resins harden and cure in the manufacturing process. Parts that must operate in a high heat environment, where softening or melting cannot be tolerated, are best manufactured using thermoset molding materials and thermoset injection molding techniques.

Thermoplastic Molding

Many highly critical parts are manufactured by the thermoplastic injection molding technique. Components having specific use and requirements are made from thermoplastic compounds engineered to meet these requirements. Optimal properties of components molded from engineered thermoplastic compounds can be attained only through the proper and precise control of the molding process. The associates at Southwest Plastics, located in Los Angeles California, are committed to delivering quality, value and service to our customers.
