Detailed Introduction

This automotive connector injection mold is a multi-cavity precision mold developed for male automotive wire harness plug housings. The mold core adopts a 4-cavity symmetrical layout, equipped with dedicated balanced runner system to ensure uniform plastic melt filling for each connector cavity, effectively avoiding product short shot, warpage and dimensional inconsistency during mass production. The molded black plastic connector finished parts feature multi-hole terminal positioning structures, which match automotive wiring harness assembly standards for stable plugging performance.

The whole mold manufacturing workflow strictly follows precision mold processing standards: complex connector cavity contours are finished via 5-axis CNC and sinker EDM micro-machining; mold steel undergoes vacuum quenching & tempering heat treatment to boost surface hardness and wear resistance; ultra-precision grinding and mirror polishing eliminate surface burrs to guarantee smooth plastic demolding. Optional nitriding or PVD coating can be added on cavity surfaces to enhance corrosion resistance against glass-filled PA66, PA12 and other automotive engineering plastics.

All mold components pass full CMM coordinate measurement inspection before assembly to control geometric tolerances of cavity depth, pin position and parting line. We fully support custom development based on customer 2D/3D drawings or physical connector samples. Cavity quantity, mold steel grade, surface treatment and ejection structure can be adjusted according to customer daily output, plastic material type and service life requirements, to meet high-volume, high-precision production demands of automotive wiring connector components.
