Precision Injection Molds & Optical Tooling
Shenzhen-based GPTMOLD designs and manufactures custom injection molds for automotive, electronics and industrial applications, with particular expertise in precision optical lens molds and inserts. We align DFM, mold design, trials and inspection with part geometry, surface requirements and agreed acceptance criteria.
Who We AreA Shenzhen-based mold manufacturer supporting projects across several part types and applications.
Moldmaking CapabilitiesExplore optical, two-shot, automotive and other tooling routes for your part.
Engineering & ToolmakingReview DFM, tool design, machining and mold trials around your part.
Quality & Project SupportAgree acceptance criteria and review samples, inspection and handover.
Optical MoldsTooling for optical parts, with surface and functional requirements defined in the project brief.
Clear & Transparent MoldsExplore tooling considerations for transparent plastic parts and agreed appearance requirements.
Multi-Shot MoldingReview multi-material or multi-color part geometry and the proposed molding sequence.
Liquid Silicone Rubber (LSR) MoldsDiscuss silicone-part requirements, tooling approach and the intended production process.
SMC & BMC MoldsReview composite-part geometry, material requirements and the proposed mold construction.
Molds for Plated Plastic PartsDiscuss tooling for plastic parts intended for plating and the relevant surface requirements.
Our Mold Manufacturing Process
From your part brief to sample approval, each stage keeps requirements, engineering decisions and acceptance criteria clear.
- Project Brief & Quotation
Share CAD data, material, volume and the requirements used to judge the part.
- DFM & Mold Design
Review geometry, tooling approach and any risks that need a decision before build.
- Mold Manufacturing
Manufacture and assemble the mold against the agreed design and project scope.
- Mold Trial & Sampling
Evaluate tool operation and molded parts against the agreed trial objectives.
- Sample Review
Check dimensions, appearance and functional requirements; record any needed changes.
- Approval & Handover
Confirm acceptance evidence, handover items and the next production or shipping step.
Why Work With GPTMOLD
Application-focused moldmaking. GPTMOLD develops custom injection molds for optical, automotive, electronics and industrial parts. We review part geometry, material, appearance and intended use to align the tooling approach with your requirements.
Engineering review before build. DFM and mold-design discussions help surface manufacturability questions while changes are easier to address. The part brief keeps open items visible before tool construction.
Quality checkpoints tied to the brief. Mold-trial samples can be evaluated against agreed dimensions, appearance and function. The findings guide any needed adjustments and provide a clear basis for sample approval and handover.
