Custom BMC, SMC & Phenolic Molds

Choosing between thermoset injection molding vs thermoplastic injection molding affects part life, tooling cost, production speed, and end-of-life options. Engineers comparing the best material for high-temperature molded parts or a thermoset injection molding cost comparison must evaluate epoxy molding compound, engineering thermoplastics, and compression molding—not just resin price. The

A thermoset injection mold shapes materials such as phenolic, melamine, epoxy, and thermoset polyester under heat and pressure. Unlike thermoplastics, these materials form permanent cross-links during curing and cannot be melted back into a liquid. This guide explains the thermoset injection molding process, custom thermoset injection mold tooling, and the difference between thermoset compression

A Thermoset Compression Mold forms heat-curing materials under pressure and temperature. Unlike thermoplastics, thermosets do not melt again after they cure. The thermoset compression molding process is used to make electrical insulators, automotive parts, appliance housings, industrial components, and other products that must resist heat, chemicals, and electrical current. This guide explains

Compression mold shrinkage can change the size, flatness, and fit of BMC and SMC parts after molding. The problem often starts with the compound, mold temperature, or fiber direction, but it appears later as a dimensional inspection failure.

Thermoset injection molding flash is a thin unwanted layer of cured material that appears at the mold parting line, ejector pins, inserts, or vents. The most common tooling causes are poor mold shutoff, worn parting surfaces, blocked venting, weak support, and incorrect flash land design. This guide explains how overseas buyers and distributors can identify the cause, confirm it with

Thermoset molding problems often start with unstable heat, not with the press or raw material. In thermoset injection molding, mold temperature control, curing consistency, and thermal uniformity decide whether a part fills correctly and releases without damage.
