Heat Resistant Plastic Parts

The Thermoset family of plastic materials harden and cure in the molding process as the molecules actually crosslink in a chemical reaction and set into a final shape. Additional No addition of heat will not soften or melt the material. As a result, thermosets are advantageous have their advantage in any high heat environment where softening or melting cannot be tolerated. Domestically products, such as ashtrays, cooking utensils, and cookware handles are produced from thermosets. Thermosets are also used in electrical, electronic and military applications. Some examples of thermoset materials are phenolics, epoxies, melamines and diallyl phthalate.

Thermosets can be molded using the compression, transfer or injection molding processes. Southwest Plastics has extensive capabilities in molding thermoset materials using all three of these processes.

Thermoset Injection

In order to shorten cycles and lower costs, some thermoset materials have been developed that can be injection molded. The standard injection molding machine must be modified by way of a specialized screw and barrel in order to injection mold thermoset materials. Southwest Plastics has been injection molding thermoset materials for many years and has the expertise to make your next project a success.
