Custom Motor Housing Casting Parts China Manufactuerer - FUERD
Aluminum die cast motor housings are now popular for electrical motor manufacturers. Compared with iron cast motor housings, aluminum die cast ones have many advantages, such as light weight, low noise, low cost and high yield. In western europe, nearly 98% of common motor housings are produced by aluminum die casting process. Because of its large demand of the motor, the aluminum die cast motor housing and head also has a large market.

FUERD die casting has been supplying certain types of motor housing and head for several motor manufacturers. The various types of die cast motor housings almost cover all our different tonnage machines. 

Advantages of Aluminum Die Cast Motor Housings

The adoption of aluminum die cast motor housings has become a significant market trend due to its numerous advantages. Many motor manufacturers have transitioned from iron cast motor housings to aluminum die cast ones.

  1. Lightweight: Aluminum alloy has a low weight, making die cast motor housings lighter compared to conventional iron cast housings. This lightweight design offers benefits such as improved handling, reduced vehicle weight, and enhanced fuel efficiency.

  2. Low Noise: Aluminum die cast housings can be designed with greater flexibility, resulting in reduced noise levels. The material properties and casting techniques contribute to effective noise dampening, leading to quieter motor operation.

  3. Excellent Conductivity: Aluminum alloy exhibits excellent heat conductivity, allowing for efficient heat dissipation in motor applications. This helps maintain optimal motor performance by preventing overheating.

  4. Cost-Effective: Aluminum alloy is generally more cost-effective than iron. Additionally, the mass production capabilities of the aluminum die casting process result in reduced unit costs. Consequently, an aluminum die cast motor housing can be more affordable than an iron housing of the same size.

Compared to Iron Cast Motor Housings:

While iron cast motor housings are still utilized for heavy and large motors, there are notable differences compared to aluminum die cast housings.

  1. Production Process: Iron cast motor housings require labor-intensive sand casting processes, which can drive up unit costs. Although the initial investment in sand casting molds may be lower, the overall production yield is lower compared to aluminum die casting.

  2. Weight and Heat Conductivity: Iron cast motor housings tend to be heavier than their aluminum counterparts. Additionally, iron has lower heat conductivity, which can lead to increased heat retention and potential performance issues in motors.

In summary, the advantages of aluminum die cast motor housings, including lightweight construction, noise reduction, excellent conductivity, and cost-effectiveness, have prompted the industry shift towards their adoption. However, iron cast motor housings still have their place in applications involving heavy loads or where lower initial investment in sand casting molds is preferred.
