Founded in Lehighton in 1979, Technical Process and Engineering, Inc. designs and builds continuous mixers, extruders, and turnkey compounding systems for plastics and rubber manufacturers. Its Pennsylvania operation also makes close-tolerance replacement parts in-house and supports equipment through rebuilds, retrofits, and 24/7/365 emergency service. A recent facility expansion and new five-axis machining center have increased its capacity for compounding equipment and precision rotor production.
