Automotive Battery Cover Injection Molding

Featuring a streamlined curved top and an integrated side mounting base, this white thermoplastic cover serves as a protective enclosure for automotive battery modules. The arc-shaped surface provides mechanical isolation and impact resistance, while the rectangular base facilitates secure locking assembly, ensuring stable positioning and structural support for internal battery components.

Large-area thin-wall injection molding requires strict control over shrinkage uniformity to suppress warping and maintain dimensional stability across installation holes and assembly contours. High-gloss mold cavities are essential to eliminate weld lines, sink marks, and flow traces, ensuring visual consistency in white plastic parts and meeting tight assembly tolerances for battery pack integration.

The facility utilizes slow wire EDM and mirror-finish EDM equipment to construct high-precision mold cavities, supported by vertical and horizontal injection molding machines for end-to-end production from tooling development to mass manufacturing. Quality assurance relies on CMM imaging systems and CCD automatic inspection to monitor critical assembly dimensions, flatness, and surface defects, delivering consistent quality standards required for automotive battery components.
