Motor housings are core structural and protective components in electric motors and drive systems. They provide mechanical support, protect internal components from environmental factors, assist with heat dissipation, and ensure proper alignment of the rotor and stator during operation.
Aluminum die casting is widely used for motor housings due to its excellent thermal conductivity, lightweight properties, and ability to form complex geometries with high dimensional accuracy suitable for mass production.
High-pressure die casting (HPDC)
In-house mold design and tooling development
CNC machining of mounting surfaces, bearing seats, and sealing interfaces
Optional surface treatments: shot blasting, powder coating, anodizing, or e-coating
Lightweight aluminum structure
Excellent heat dissipation for motor performance and durability
High dimensional accuracy and consistency
Good structural rigidity and vibration resistance
Corrosion resistance with appropriate surface treatment
Suitable for automated assembly and high-volume production
ADC12 / A380 aluminum alloy – standard choice for good castability and thermal performance
A356 aluminum alloy – available when higher mechanical strength is required
Material selection depends on motor type, operating temperature, and mechanical load conditions.
Electric vehicle (EV) drive motors
Industrial electric motors
Servo and stepper motors
Robotics and automation motors
Household appliance motors
Power tools and equipment motors
X-ray inspection for internal casting integrity
CMM dimensional measurement
Visual and surface quality inspection
Thermal and mechanical property verification when required
Integrated die casting and tooling capability
DFM (Design for Manufacturing) support in early development
Prototype sampling and mass production capability
Experience supplying motor housing components
Custom manufacturing based on customer drawings and specifications
