In-house tooling is the foundation of quality. Our experienced mold engineers utilize UG/NX, AutoCAD to design high-precision progressive dies and injection molds. Every tool is CMM-inspected and trial-run before mass production, ensuring dimensional accuracy and repeatability.
Equipped with high-speed punching machines (up to 60T), we produce millions of terminals and connector pins monthly. SPC (Statistical Process Control) monitors critical dimensions in real-time, and coil feeders ensure continuous, stable output with tight tolerances (±0.01mm).
Our injection workshop runs 40+ machines (80T–250T) for connector housings, seals and custom plastic parts. Scientific molding parameters, robotic arm take-out and automatic sorting ensure consistent part quality. Materials include PA66, PBT, LCP and other engineering plastics.
Semi-automated and manual assembly lines handle crimping, ultrasonic welding, taping and final testing. Every harness undergoes 100% continuity test and crimp force monitoring. Labels, seals and custom routing are available per customer specifications.
Introduction When designing a new component through injection molding, one of the most important questions engineers face is:Which plastic should I choose for my application? The material selection process determines not only the mechanical strength and durability of a part but also its cost, manufacturability, and compliance with industry standards.
Introduction Injection molding is one of the most versatile and widely used manufacturing processes. From automotive parts to consumer products, medical devices, and industrial components, millions of parts are produced daily using this method. A key factor that determines performance, cost, and durability of molded components is thetype of plastic
