Optical Molds & Precision Tooling
GPTMOLD manufactures optical molds, optical mold components and custom injection molds in Shenzhen, China. We make lens molds and precision inserts for automotive lighting, consumer electronics and industrial parts, together with two-shot tooling and overmolding.
For PC and PMMA optical injection molding, our engineers review surface requirements, gate locations and assembly dimensions before mold trials. Samples are checked against the drawing and agreed inspection plan.
