Plastic Injection OEM & Custom Mold Development

One-stop injection OEM: custom mold development (CAD/CAM, runners, cooling) and precision molding, in PP/ABS/PC/PMMA, for lamp covers, agricultural parts and housings.

01Precision from Design to Mass Production

Whether it's a structurally complex tech-product housing or a weather-resistant traditional industrial part, plastic injection molding is the core technology for efficient, high-precision mass production. Guann-Ming offers one-stop injection-molding OEM — from mold development to stable production — turning your ideas into real products.

02Core Process: Mold-making and Molding Hand in Hand

A perfect plastic part depends on the union of "mold design" and "molding craft":

  1. Custom mold development: the mold is the soul of the product. Using advanced CAD / CAM, we evaluate shrinkage, runner design (hot / cold) and cooling systems to ensure long mold life and precision.
  2. Precision molding: by precisely controlling injection pressure, speed, temperature and holding time, we overcome shrinkage, warpage and voids, keeping every batch highly consistent.

03Diverse Materials & Unlimited Applications

Guann-Ming is not limited to one industry — with rich experience across PP, ABS, PC, PMMA and engineering plastics, we take on diverse commissions:

  • Optical & lighting: high-transparency materials for lamp covers and shades with demanding surface finish.
  • Traditional & agricultural parts: UV-resistant, high-toughness plastics for weatherproof, high-tensile metal-replacement parts such as agricultural pins.
  • ICT & electronics: flame-retardant (UL 94) electronic housings with structural strength.

04Why Choose Our Injection OEM?

Guann-Ming has extensive composite-material molding experience and flexible capacity. Whether you're a tech start-up needing complex structures or a manufacturer needing stable high-volume runs, we provide professional support from mold DFM evaluation and prototyping to mass production.
