High-Performance Plastic Injection Mold for EV Automotive Lighting Systems
As electric vehicles (EVs) undergo rapid design revolutions, automotive headlights have evolved from simple illumination units into highly sophisticated aerodynamic, optical, and structural assemblies. At CNMOULDING (chinamoldmaker.org / cnmoulding.com), we deliver heavy-duty, micron-level precision automotive tooling specifically engineered for the demanding quality standards of modern new energy vehicle OEMs.
Our Model CHINA-088 is a premier single-cavity automotive headlight injection mold, optimized for optical clarity, flawless surface finishes, and high-volume manufacturing stability.

Key Technical Advantages of CNMOULDING Tooling
1. Premium Optical Grade Mold Steel Selection
To prevent cosmetic defects, weld lines, or cloudy finishes on the headlight component, we offer core and cavity inserts machined from premium S136 (high mirror-polish grade) or 2738 / 718H pre-hardened steels. Advanced interim treatments like vacuum quenching are applied to boost core longevity.
2. Advanced Post-Processing: Low-Deformation Nitriding
We apply low-temperature gas nitriding for structural elements of the mold. This achieves an extreme surface hardness greater than HV850 with absolute minimal thermal deformation. This eliminates the need for aggressive post-quench correcting and drastically enhances the wear resistance against abrasive automotive resins.
3. Optimized Cycle-Water Cooling Systems
Headlight housings are prone to uneven thermal shrinkage and warpage. Our engineering team utilizes Moldflow analysis to build an optimal cyclical cooling water jacket into the tool. This maximizes heat dissipation uniformity, reduces your injection molding cycle times, and lowers overall piece-part costs.
4. Extended Tool Life Guarantee
Built with rigid engineering safety factors, a tool utilizing P20 steel is guaranteed for no less than 500,000 cycles under normal manufacturing conditions. Premium steels like S136 easily exceed this threshold for multi-million shot production.
