Detailed Introduction

This full automotive connector component series adopts two core high-temperature engineering plastics to adapt diverse vehicle working conditions.

LCP material features ultra-low thermal expansion and high-frequency insulation performance, applied to dense miniature multi-pin signal terminal blocks and tiny positioning auxiliary parts inside engine cabins, effectively avoiding terminal offset caused by long-term high-temperature heating. V0 flame-retardant glass-filled PBT delivers outstanding mechanical rigidity and impact resistance, ideal for large multi-circuit junction boxes, cylindrical high-voltage plugs and mounting brackets that bear heavy mechanical load and circuit heating risks.

The product portfolio covers all core matching parts of automotive wiring harness systems: large grid multi-row signal housings, circular high-current power plugs, color-coded modular signal blocks, vehicle fixed mounting brackets, terminal locking wedges, anti-retention pins and sealing positioning washers. Multi-color differentiation (black, orange, red, blue, green, gray, beige) is adopted to distinguish power, signal, ground and high-voltage circuits for quick assembly inspection. Every main housing and auxiliary accessory is designed with matched precision clearance, forming dual anti-loosening protection to eliminate poor contact caused by vehicle vibration. Optimized thin-wall melt flow mold design solves shrinkage, warpage and flash defects during molding high-temperature flame-retardant plastics.

Complete Production Workflow

1. Custom precision mold core processing: 5-axis CNC rough & fine milling, micro sinker EDM for complex curved contours and tiny grid pin slots
2. Vacuum stress relief heat treatment for mold steel to stabilize cavity dimensions under continuous high-temperature injection cycles
3. Multi-stage mirror polishing to reduce melt adhesion of LCP/PBT flame-retardant plastic and lower demolding resistance
4. Segmented temperature-controlled precision injection molding with customizable color masterbatch blending
5. Post-molding full 3D coordinate dimensional inspection, burr trimming, high-temperature aging and flame retardancy safety testing

All finished plastic components pass thermal stability and vibration anti-loosening aging verification. Custom development is fully supported based on customer circuit layout drawings: pin grid quantity, shell wall thickness, plastic flame retardant grade, locking mechanism and color scheme can be adjusted according to operating temperature, current load and vehicle assembly requirements. The full diversified specification series realizes one-stop supporting supply from miniature sensor signal connectors to new energy vehicle high-voltage power distribution assemblies.
