Our Engineering Department is always prepared to help our customers evaluate the proper lining of materials for use with specific resins, additives and operating conditions.

Rebuilt Barrels

When rebuilding your barrel is the answer, we can help! Our Engineering Department will evaluate your operating conditions and recommend the approriate materials. Our detailed process always insures top quality. General Plastex's rebuilding process includes re-machining mating surfaces, threaded holes, counter bores, transducer and thermocouple connectors.
