Injection Molding Thermoset for Automotive
Comments Off on Injection Molding Thermoset for Automotive
As a performance grade composite, thermoset plastics are used in a variety of challenging automotive environments and applications. Thermosets provide excellent heat resistance and temperature deflection to avoid deforming or degradation when exposed to high operating temperatures. Utilizing an injection molding process with thermoset not only gives an automotive part the physical and durability properties, but provides a high-throughput option for high volume programs that require large outputs of product. Injection molding thermosets use faster cycle times than compression, and injection molds can built with higher cavitation as well. Automotive applications that rely on injection molded thermoset parts include powertrain and transmission parts that are in contact with automotive fluids and oils. Interior ash cups were once a high-demand component utilizing a thermoset injection molding process. With the increase and development of Electric Vehicles and electrification in vehicles, thermosets are a perfect match for electrical applications such as sensors, connectors, housings, as well as charging components.

Why are thermoset composites like phenolic and bulk molding compound commonly used material in automotive applications? Molded thermoset parts and components have excellent material properties with regards to resistance against high temperatures, corrosion, and chemicals and automotive fluids. Processing wise, thermosets may be injection molded, or compression molded.
