Detailed Introduction

This split two-plate mold set is engineered for orange high-voltage resistant automotive connectors widely used in new energy vehicles. The fixed mold plate is equipped with micro pin inserts to form terminal positioning slots inside the connector, while the movable mold plate shapes the outer locking shell with mounting lugs. Optimized short runner layout avoids carbonization and flow marks when molding high-temperature PPA and PA66 flame-retardant plastics, meeting high safety standards for EV high-voltage electrical parts.

The whole mold follows strict high-temperature precision machining standards: tiny pin contours are processed via micro sinker EDM and wire cutting to ensure consistent pin spacing and insulation wall thickness; mold steel undergoes vacuum quenching & tempering heat treatment to improve thermal stability and wear resistance under long-term high injection temperature; multi-stage mirror polishing eliminates sharp edges to prevent plastic flash that may cause high-voltage leakage risks. Optional PVD coating can be applied to cavity surfaces to resist corrosion from flame-retardant filled engineering plastics.

All mold inserts, pin cores and mold base pass full CMM coordinate measurement inspection before assembly to strictly control insulation wall thickness, pin concentricity and mounting hole dimensional accuracy. We fully support custom development based on customer 2D/3D drawings or physical connector samples. Cavity layout, pin quantity, mold steel grade and surface treatment can be adjusted according to vehicle voltage grade, flame retardant plastic material and service life requirements, satisfying high-safety mass production demands of new energy vehicle high-voltage connectors.
