Aluminum Motor Housing for High Performance Vehicles

High-Performance Aluminum Die-Casting Components for Electric Vehicle Manufacturing

Sunhang Foundry specializes in delivering precision-engineered aluminum die-casting solutions tailored for the rapidly evolving electric vehicle (EV) industry. With a strong focus on innovation, material science, and intelligent manufacturing, we produce critical components such as motor housings, battery enclosures, and structural casings that meet the highest standards of performance, durability, and efficiency. Our products are designed to support the global shift toward sustainable mobility by combining advanced metallurgy with state-of-the-art production techniques.

Key strengths include ultra-precise dimensional control (±0.05mm), superior surface finish (Ra ≤ 1.6 μm), and optimized thermal management—ensuring long-term reliability under demanding operating conditions. Through proprietary alloy development and T6 heat treatment processes, our castings achieve tensile strengths exceeding 380 MPa while maintaining excellent corrosion resistance and lightweight characteristics essential for EV weight reduction and energy efficiency.

Our manufacturing capabilities span custom aluminum extrusions, precision casting profiles, and CNC-machined engine covers—ideal for applications requiring exact fitment, enhanced mechanical integrity, and easy assembly. Whether it’s an aluminum motor housing for high-torque electric motors or a die-cast battery enclosure offering superior sealing and impact protection, each part undergoes rigorous quality assurance and surface finishing options like powder coating for added environmental resilience.

These high-strength aluminum components are widely used across industrial automation, automotive engineering, and renewable energy systems where robustness, thermal conductivity, and low weight are critical design factors. From electric powertrain enclosures to custom engine casings, Sunhang Foundry supports OEMs and Tier 1 suppliers seeking scalable, high-performance solutions aligned with future-proof EV architecture.

Customers consistently praise our ability to deliver consistent quality at scale, noting how our materials reduce maintenance costs and improve system longevity compared to traditional steel alternatives. The seamless integration of smart production lines ensures rapid turnaround without compromising precision—a key advantage in fast-paced EV development cycles.

Common inquiries often center around lead times, customization flexibility, and compliance with international standards such as ISO 9001 and IATF 16949. We provide full traceability documentation and can accommodate specific requirements for electrical insulation, vibration damping, or electromagnetic shielding based on customer specifications. Additionally, our team offers technical consultation for component redesigns aimed at optimizing manufacturability and reducing overall lifecycle costs.
