Our Story — From Workshop to Global Plastic Machining Manufacturer

PlasticPartsCustom began in 2007 as a small CNC workshop in Suzhou, China with a simple mission: make precision plastic parts that global OEMs can trust. Today, we are a full-service custom plastic machining manufacturer operating 20 CNC machining centers and serving over 1,000 clients in the medical device, automotive, aerospace, semiconductor, food processing, and industrial equipment sectors.

What sets us apart is our engineering-first approach. Every project begins with a DFM review by our senior engineers who average 12+ years in precision machining. We combine advanced 3-axis, 4-axis, and 5-axis CNC capabilities with a rigorous ISO 9001:2015 quality management system. Full material traceability, first article inspection reports per AS9102, and CMM dimensional reports are standard with every shipment.

We specialize in engineering plastics: PEEK, PTFE, UHMW-PE, Delrin (POM), Nylon, Acrylic, Polycarbonate, PPS, PSU, PEI (Ultem), and more. Our capabilities span CNC machining, injection molding, 3D printing, and plastic welding. Prototype to production volumes with no minimum order quantity. Learn more on our Capabilities page.
