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.
Who We Are
Based in Shenzhen since 2008, GPTMOLD makes custom injection molds for automotive lighting, electronics, optical and industrial parts. Meet the team behind design, tooling and sample review.
Moldmaking Capabilities
Our tooling includes optical lens molds and inserts, two-shot molds, overmolding, LSR and SMC/BMC molds. Material, surface finish and part geometry guide the mold design.
Engineering & Toolmaking
DFM review addresses parting lines, draft, gates and ejection before tool construction. Mold flow analysis, 3D design, machining, fitting and assembly follow the project requirements.
Quality & Project Support
Trial samples are checked against agreed dimensions, appearance and functional criteria. Project engineers track drawing revisions, inspection findings and customer approvals through handover.

About GPTMOLD
Founded in 2008, GPTMOLD manufactures custom injection molds for automotive lighting, consumer electronics, optics and industrial components. Our work brings together mold design, toolmaking, trial sampling and inspection at our Shenzhen operation.
Optical lens molds and precision inserts are a core part of our business, alongside two-shot molds and overmolding. For optical mold components and clear plastic parts, we review the resin, optical geometry and surface finish, including mirror polishing, before tool construction.
Our design and project engineers work from the customer's drawings and acceptance requirements. They coordinate DFM review, machining, fitting and assembly, then review trial parts and inspection findings with the customer before approval and handover.
