This mold is developed for high-precision automotive housing production where dimensional consistency and surface finish are critical.

Mold Structure & Engineering Capability

This automotive wiper housing injection mold adopts a stable two-plate structure with optimized side gate design to ensure balanced filling and minimal warpage.

The core and cavity use SKD61 tool steel with controlled heat treatment, providing:

Strong wear resistance

Stable hardness control

Excellent polishing performance

Long mold service life for automotive mass production

High-precision electrical discharge machining (EDM) is applied to achieve fine details required in steering lever housing components.

Automotive Mold Development Process

In automotive tooling projects, reducing mold modification cycles is critical to shorten lead time and control costs.

Our mold development process includes:

Dimensional pre-compensation design

Progressive grinding adjustment strategy

Precision fitting and assembly control

Trial mold validation before delivery

By designing the cavity slightly undersized in the initial stage and adjusting progressively, we minimize revision frequency and achieve required tolerance more efficiently.
