Durable Die-Cast Solutions for Modern Vehicle Electronics

Modern vehicles demand electronic components that survive extreme environments — vibration, temperature cycles, moisture, and electromagnetic interference — while remaining lightweight and manufacturable at scale.

At Dongguan GuangWei Communication Technology Co., Ltd., we design and manufacture precision zinc and magnesium alloy die-cast housings tailored for automotive connectors, FAKRA shells, EV charging components, and other vehicle electronics that require both durability and performance.

Advantages

Our approach is engineered around three priorities: robustness, thermal resilience, and production consistency.

Robust Mechanical Design

We optimize part geometry, wall thickness, and ribbing to deliver enclosures and connector shells that withstand mechanical shock and long-term vibrational fatigue. GuangWei’s die-cast parts are engineered for secure mating interfaces, reliable fastener locations, and precise alignment with PCBs and connectors — minimizing field failures and assembly rework.

Thermal and Environmental Performance

Magnesium and zinc alloys provide ideal combinations of lightweight strength and thermal management. For EV charging modules and power converters, our parts are designed to effectively dissipate heat, support thermal cycling, and maintain mechanical integrity under elevated temperatures. We also integrate sealing features and finishing processes that protect against corrosion, salt spray, and moisture ingress.

EMI/EMC and Signal Integrity

Many automotive systems rely on clean, interference-free signals. Zinc alloy housings deliver excellent inherent EMI shielding; GuangWei engineers grounding paths and contact points into parts to ensure consistent shielding effectiveness across mass-produced units. This is critical for RF connectors like FAKRA shells and sensor housings used in advanced driver-assistance systems (ADAS).

From Prototype to Production — Full-Process Integration

GuangWei’s vertically integrated capabilities — from engineering and mold design to casting, CNC machining, surface finishing, and automated assembly — reduce risk and shorten time-to-market. We handle both fine, thin-walled connector shells and larger structural housings with equal precision, ensuring repeatability and tight tolerances throughout volume production runs. Our in-house testing and inspection (dimensional measurement, coating adhesion, and environmental tests) guarantee parts meet automotive reliability standards.

Differentiators that matter to automotive OEMs and Tier suppliers
