From DFM analysis to mass production delivery — full-process precision mold solutions under one roof
We specialize in precision molds for optical, medical, automotive electronics, consumer electronics, cosmetic packaging, and LED lenses — covering the entire closed-loop from product structure evaluation to mold mass production delivery. We support nano-level ultra-high precision optical molds, thin-wall medical consumable molds, and high-gloss mirror finish molds.
Six core sub-services — from DFM analysis to final mold assembly — all completed in-house with imported precision equipment.
We receive client product drawings or prototypes and conduct comprehensive DFM review covering mold feasibility, demolding, shrinkage, wall thickness, production cost, and injection defect prediction to eliminate mass production risks in advance.
We use UG full 3D standardized layer mold design with unified part naming conventions, delivering complete 3D/2D engineering drawings for cavity inserts, plates, and standard components.
We perform mold flow, cooling, warpage, and stress simulation analysis to optimize gate, cooling channel, and venting design — reducing trial shot iterations and ensuring dimensional and appearance consistency.
Imported YASDA, Makino, and Yixin high-speed CNC, Sodick/Makino precision EDM, Moore jig grinder, and precision surface grinders complete cavity and plate machining with 0.001~0.005mm precision.
Our dedicated polishing workshop delivers standard mirror, high-gloss mirror, and nano-level optical mirror polishing. Optical mold mirror finish reaches 0.000001mm nano precision with no orange peel, scratches, or waviness defects.
Standardized mold assembly with multiple trial shot adjustments, full dimensional inspection using CMM, 2.5D measuring instruments, and height gauges. A complete trial report is issued before delivery of the production-ready mold.
Imported YASDA, Makino, Moore jig grinders, and nano-level polishing — delivering world-class precision mold solutions.
Nano-level optical mold machining capability, supplying lens products for Huawei, Apple, OPPO, and VIVO as end customers.
Complete set of imported ultra-high precision machining equipment — jig grinders, high-precision CNC, and precision EDM machines all in-house.
Standardized UG 3D mold design system with integrated ERP digital management, ensuring standardized drawings and machining workflows.
Independent dedicated mirror polishing workshop with mature optical mirror polishing processes, suitable for high-transparency products such as LED lenses and automotive lenses.
Complete QC inspection system with full coverage of CMM, 2.5D measuring instruments, and height gauges. Full dimensional inspection and control during mold trial.
In-house mold workshop with full-process in-house machining — no outsourcing, ensuring controllable delivery lead times.
