OEM Aluminum Die Casting Services for Motor Parts Electric Motor Housing Casting

As a specialized OEM manufacturer, we provide precision aluminum die casting services specifically engineered for motor components and electric motor housings. Our technical expertise in die casting technology combined with comprehensive understanding of motor design requirements enables us to deliver housings that optimize performance, thermal management, and durability for various electric motor applications.

Material Selection for Motor Applications

We utilize premium aluminum alloys specifically chosen for their electrical and mechanical properties:

A380 Aluminum Alloy
This industry-standard alloy offers an optimal balance of strength, durability, and thermal conductivity (96 W/m·K), with tensile strength reaching 324 MPa. The material's excellent castability ensures precise reproduction of complex housing geometries while maintaining dimensional stability under thermal cycling conditions typical in motor operation.

ADC12 Aluminum Alloy
Known for its superior pressure tightness and corrosion resistance, ADC12 provides excellent electromagnetic shielding properties crucial for motor applications. With tensile strength of 230-310 MPa and good machinability, this alloy is particularly suitable for housings requiring intricate internal structures and precise bearing seat tolerances.
