Plastic injection molding delivers complex plastic parts at high speed and low per-unit cost — and when a part demands tighter tolerances, threads or secondary features, CNC machining finishes the job. Our CNC Machining Plastic Injection Molding Parts combine both processes under one roof: precision-molded blanks refined by CNC milling, drilling, tapping and surface finishing to achieve dimensional accuracy beyond as-molded limits.
Working with ABS, PC, PA66, POM, PP, PBT+GF and more, we support the full journey from DFM review and mold development to mass production and post-machining, with ISO 9001 quality control at every stage. From precision housings, gears and brackets to connectors, we deliver consistent, cost-effective parts for automotive, electronics, industrial and consumer applications.
One-stop molding + machining — molded blanks plus CNC milling, drilling and tapping under one roof: tighter tolerances, threads and undercuts without extra suppliers or handling delays.
Material flexibility — ABS, PC, PA66, POM, PP, PBT+GF, PMMA and custom grades, with glass-fiber or flame-retardant fillers on request for strength or safety requirements.
Precision & repeatability — ±0.05 mm on molded dimensions and ±0.01–0.02 mm on CNC-machined features, verified by CMM inspection and process control during mass production.
Fast DFM & mold development — free design-for-manufacturability analysis and 3D-printed prototype validation before steel cutting, shortening mold lead time and de-risking the project.
Surface finishing options — painting, plating, texture/matte, polishing and laser engraving, with Pantone/RAL color matching for consistent brand appearance.
