The motor housing needs to have high strength, good heat dissipation, and excellent electromagnetic shielding. Therefore, aluminum is usually used in the die casting process as the material of the motor housing.

ADC6 is an excellent material for motor housings. It is a low-copper, high-silicon die-cast alloy with excellent castability and certain mechanical properties. The main components of ADC6 are aluminum, silicon and sodium. Due to its low copper content, ADC6 is not prone to defects such as pores.It is ideal for products such as motor casings that require high strength and high castability.

ADC12 is a die-cast aluminum with high strength, corrosion resistance and good machinability.
Its main components are aluminum, copper, indium and platinum. It is widely used in motors for its excellent mechanical strength and corrosion resistance. However, due to the high copper content, castings are prone to defects such as pores and thermal cracks, and high-pressure shooting technology is required for casting.

ADC5 is a high-performance, high-strength, high-temperature die-cast aluminum. The main components of ADC5 are aluminum, zinc and platinum. Because of its excellent high-temperature performance and strength, it is widely used in high-load fields such as motors and engines. However, due to the high zinc content, castings are prone to defects such as shrinkage cavities and pores, requiring strict preheating and temperature control measures.

Precisely control the die casting process parameters to ensure accurate dimensions of the housing. High-precision CNC processing equipment is used for secondary processing to ensure that the dimensions meet the requirements.

The function of the ribs is to increase the strength and rigidity of the die casting, reduce the shrinkage deformation of the casting, avoid deformation when the workpiece is ejected from the mold, and serve as an auxiliary circuit (pathway for the flow of molten material) when filling the molten material.

The following requirements should be noted:
The thickness of the ribs of the die casting parts should be smaller than the wall thickness where it is located, generally 2/3~3/4 of the wall thickness.

Different motors may have different requirements for housing materials, and appropriate aluminum alloy materials need to be selected.

According to the requirements and usage environment of motors, select appropriate aluminum alloy materials to ensure the mechanical properties and corrosion resistance of the housing.
