Established in 1968, Philadelphia’s Engineered Plastics Company (EPC) designs tooling and produces custom injection-molded plastic parts, with production running around the clock. Its in-house path from mold design and prototyping through quality control and finishing lets EPC handle complicated designs and both small and large production runs under one roof. The company’s parts are made in the USA, and EPC is an approved vendor for manufacturers including Honeywell, Rockwell International, and Ingersoll Rand.
