Core Capabilities
From raw compound to finished part — LSR injection, precision molds, optical silicone, medical-grade parts, silicone foam and plastic injection, all under one roof.

01 · LSR Injection
300K-class cleanroom for medical, automotive and optical LSR. Vertical & horizontal machines, cold-runner valve-gate molds built in-house.
Explore LSR Injection Molding
02 · Mold Making
In-house tooling: 12 CNC machines, CMM inspection, 8 senior mold designers with 5–10+ years of experience in UG NX, Mastercam, SolidWorks.
Explore Mold-Making
03 · Optical Silicone
RI 1.43–1.46, 84+ Shore A optical-grade LSR for LED lenses, light guides, and automotive optics. Replaces Dow / Wacker at 40% lower cost.
Explore Optical Silicone
04 · Medical Silicone
ISO 13485 certified. Biocompatible LSR and HCR parts for medical devices, FDA / LFGB compliant, full traceability via WMS + MES.
Explore Medical Silicone
05 · Silicone Foam
Four processes: calendering, extrusion, molding, die-cutting. For EV battery seals, thermal pads, gasketing, vibration damping.
Explore Silicone Foam
06 · Plastic Injection
PP, ABS, PC, PE and other engineering plastics. LSR-overmolding on plastic substrate for 3C, consumer and industrial housings.
Explore Plastic Injection
07 · Fluoro Elastomers
FVMQ and FKM (Viton-type) molded parts — aerospace fuel seals, O-rings, gaskets, diaphragms. Fuel and solvent resistant from -60°C to +230°C.
Explore FluorosiliconeApplications
From EV battery seals to medical devices, our parts ship into the most demanding applications.

Two buildings in Sankeng Industrial Park, Tangxia, Dongguan. Every process in-house — from compound mixing to final inspection.

A dedicated design team with 5–10+ years of experience, fluent in Mastercam, UG NX, AutoCAD, SolidWorks and Pro-E. Professional document management system keeps your IP safe.

From incoming raw material to finished goods, every batch is scanned and tracked. MES goes live June 2025 with PLM module for engineering change control.
