Precision Aluminum EV Motor Housing (Electric Vehicle Motor Casing)
Product Description
developed and manufactured by Xiamen Guansheng The Precision Aluminum EV Motor Housing is a high-strength structural component designed for electric vehicle (EV) motors, Precision Machinery Co., Ltd. Using advanced 5-axis CNC machining, each housing achieves precise tolerances of up to ±0.01 mm, ensuring perfect alignment, vibration resistance, and excellent heat dissipation performance.
Engineered from premium Aluminum Alloy 6061 or 7075, this component is lightweight yet extremely durable, capable of withstanding high rotational stresses and thermal loads. Every housing undergoes precision machining, sandblasting, and anodizing treatment, resulting in enhanced corrosion protection and a smooth, professional finish suitable for automotive-grade standards.
This motor housing is an essential component in electric motors, drive systems, and hybrid power units for EVs and industrial automation. With fully customizable geometry, mounting interfaces, and surface treatments, Guansheng ensures each product meets the client’s exact engineering and aesthetic requirements.
All parts are produced under strict ISO 9001 and IATF 16949 automotive quality management standards to guarantee consistent performance and long-term reliability.
