Contract Manufacturing for Custom Plastic Parts
Based in Shenzhen, China, Plasticpartsmfg provides reliable plastic contract manufacturing for multi-part assemblies, low-to-mid volume repeat production, and scalable OEM supply. We bridge engineering design to delivery with end-to-end tooling, quality validation, secondary finishing, and ready-to-ship subassemblies.
Production Specifications OEM Ready
Integrated Turnkey Plastic Manufacturing
From multi-cavity injection tooling to precision profile extrusion and assembly, Plasticpartsmfg manages the entire production cycle under one contract workflow.
Tooling & Mold Making
In-house precision mold manufacturing for rapid bridge tooling and multi-cavity hardened steel production molds with verified draft, gating, and cooling analyses.

- • SPI standard finishes & texture matching
Repeat Serial Production
Stable cycle control across blow molding, injection molding, thermoforming, and profile extrusion with strict raw resin traceability and dimensional verification.
- • Engineering resins: PEEK, PPS, PA+GF, POM
- • Repeatable tolerances up to ±0.05 mm
- • In-line sampling & batch inspection logs
Finishing & Box-Build Assembly
Eliminate fragmented supply chains. We handle ultrasonic welding, heat staking, pad printing, surface coating, hardware insertion, and custom retail or export packaging.
- • Brass threaded insert press/heat-stake
- • Silk screening, laser marking, pad print
- • Barcode tagging & sea/air-ready crating
