Engineering And Tooling
Design engineers review the part drawing, material and functional requirements with the customer. After the tooling approach is agreed, the tooling team connects the approved design with machining, fitting and mold assembly.
Company Profile
Company Overview
GPTMOLD is a Shenzhen-based manufacturer of custom injection molds for plastic components. We support projects in automotive lighting, consumer electronics, optics and industrial applications, connecting mold design and manufacturing with trial sampling and inspection.
Precision optical lens molds and inserts are a particular strength within our broader tooling work. Our scope also includes two-shot molds, overmolding and other custom molds. Each project starts with the part drawing, material, geometry, surface and functional requirements.
From DFM review through tool construction and sample evaluation, we keep engineering questions and inspection criteria tied to the agreed brief. That gives customers a practical basis for discussing changes, reviewing trial parts and confirming approval or handover.

How Our Team Works
Trials And Quality
The team reviews mold trials and sample parts against agreed dimensions, appearance and functional criteria. Inspection findings and required adjustments are recorded before the next review or approval.
Project Coordination
Project engineers keep drawing revisions, open questions, trial feedback and customer decisions connected. Clear handovers help each team work from the same requirements through design review, validation and final handover.
