Plastic Injection Molding in China

China offers a competitive edge in plastic injection molding, balancing precision, cost, and capacity. Manufacturers in China produce complex parts with tolerance as tight as tolerance of +/- 0.025mm, and can handle virtually all types of injection materials.

Costs here are much lower than in Western markets, often 2-3 times less, driven by efficient production and lower overhead, not cutting corners. The speed is often unbeatable, with mold production typically taking 4-8 weeks and parts rolling out days after tooling is complete.
