Detailed Introduction

This complete connector component series applies two core high-temperature plastic materials to match different load and temperature working scenarios.

LCP material features ultra-low thermal expansion and high-frequency insulation performance, applied on miniature dense pin signal strips and compact sensor connectors to prevent terminal position drift under long-term high-temperature engine cabin environment. Glass fiber reinforced PBT provides superior mechanical strength and anti-abrasion capacity, ideal for large junction boxes, high-current power plugs and thick-wall insulating shells that bear frequent plugging and heavy mechanical load.

The product range includes oversized multi-grid wiring harness distribution boxes, modular multi-row terminal housings, cylindrical power insulating connectors, thin long grid positioning strips and special fluid isolation plastic shells. Every component is integrated with precise pin positioning slots, anti-reverse snap locks and matching sealing grooves, achieving zero-gap fit with metal conductive terminals. Optimized multi-channel melt flow mold design eliminates shrinkage, warpage and flash defects during high-temperature plastic injection.

Complete Production Workflow

1. Custom precision mold core processing: 5-axis CNC rough forming, micro sinker EDM for dense tiny pin hole contours
2. Vacuum stress relief heat treatment for mold steel to stabilize cavity dimension under continuous high-temperature injection cycles
3. Multi-stage mirror polishing to reduce LCP/PBT high-temperature plastic melt adhesion and lower demolding resistance
4. Segmented temperature control precision injection molding for high-performance engineering plastics
5. Post-molding full 3D coordinate inspection, burr trimming and high-temperature aging insulation testing

All finished plastic components pass dimensional verification and thermal stability aging tests. Custom development is fully supported based on customer terminal layout drawings: pin grid quantity, shell wall thickness, plastic material grade and locking/sealing structure can be adjusted according to operating temperature, current load and service life requirements. The full diversified specification series realizes one-stop supporting supply from miniature signal connectors to large new energy power distribution junction boxes.
