As the global automotive industry accelerates its transition to New Energy Vehicles (NEVs), the demand for robust, reliable, and high-performance charging infrastructure has reached unprecedented heights. At the core of this transformative ecosystem lies a pivotal manufacturing process: High-Pressure Die Casting (HPDC).

Boasting 24 years of specialized expertise in zinc, aluminum, and magnesium alloy die casting, Jinyuanfu has emerged as a trusted strategic partner for Tier 1 suppliers and OEM manufacturers across the NEV sector. This article delves into how precision die casting is redefining the performance and durability of EV charging accessories.

1. Superior Thermal Management for High-Power Charging

Modern EV fast chargers generate substantial heat during peak operation, which poses a critical threat to sensitive electronic components. Aluminum alloys—specifically ADC12 and A380—are the material of choice for charger navigation radiators and power converter enclosures, thanks to their exceptional thermal conductivity.

At Jinyuanfu, we leverage advanced die-casting simulation technologies to optimize the design of heat sink fins. This precision engineering ensures that electronics maintain stable operating temperatures even under full-load high-power delivery, directly extending the service life of charging stations and guaranteeing consistent performance over time.

2. Durability & Aesthetics Integrated in Charging Gun Housings

The charging gun serves as the primary user touchpoint for EV charging systems, requiring a perfect balance of impact resistance, weatherproofing, and ergonomic design.

Zinc Alloy Casting: Ideal for high-end charging connectors, zinc alloy delivers a premium, substantial handfeel, supports superior surface finishing (such as electroplating and powder coating), and provides inherent EMI shielding to protect signal integrity.

Magnesium Alloy: For ultra-lightweight portable chargers, magnesium alloy offers the industry-leading strength-to-weight ratio, enabling easy portability without compromising structural durability.

3. Precision Engineering for IP67 Weatherproofing

Charging infrastructure operates in harsh outdoor environments—from freezing rain and snow to scorching sunlight and dust storms. Our integrated CNC precision machining capabilities ensure that every die-cast component meets ultra-tight tolerances of ±0.01mm.

This level of precision is non-negotiable for achieving IP67 or even IP68 ingress protection ratings, effectively sealing high-voltage internal circuits against dust and moisture intrusion, and safeguarding device safety and reliability in extreme conditions.
