Aluminum pressure die cast motor body is produced by pressure die-casting process. The aluminum die-casting mold is quickly filled in the die-casting mold cavity under certain conditions under high pressure, and is rapidly cooled under certain pressure. The die-casting process is a process of organically combining and using the three die-casting production elements of die-casting alloy, die-casting mold and die-casting machine.
Aluminum pressure die cast process features:
- Aluminum die-casting molds have the advantages of high precision, low surface roughness values, and high material utilization. They can not only manufacture metal parts with complex shapes, clear outlines, and thin-walled deep cavities. Therefore, the die-casting parts are compact in structure and have high strength and hardness. high productivity.
- The latest designs of motor housings are designed for die casting production. The requirements placed on castings are very stringent. To meet component strength and corrosion resistance specification requirements, aluminum silicon cast alloys with low iron and copper contents are used.
- The housing is cooled using a liquid medium.
- To meet strength requirements, the parts are cast under vacuum and then heat treated.
Features of Aluminum Die Casting Mold
- Capable of targeted and controlled mold filling.
- Optimum filling speed can be set according to the cross-section to be filled,
- The formation of oxides and gaseous impurities is minimized.
- By using multiple risers, the wall thickness build-up distributed in the casting can be optimally replenished and shrinkage holes are largely suppressed.
Advantages of using aluminum alloy for motor body
The advantages of aluminum alloy material are light weight, good heat dissipation performance, good thermal conductivity, good plasticity in die-casting process, higher elongation than iron, low noise, and good operational stability. Aluminum alloy material used in the motor body die-casting advantages have the following 4 points:
- Good heat dissipation: motor in the working process, due to high speed operation, the motor itself produces high temperature need to release, we know that the heat capacity of aluminum is very strong, so aluminum alloy material is very suitable for die casting for motor body.
- Make the motor lighter: metal aluminum is lighter in weight, and the weight of the whole machine can be reduced. Easy to install and carry.
- Good plasticity: aluminum alloy material is lighter than steel, good thermal conductivity, good plasticity, can be die casting and elongation is higher than iron.
- aluminium motor body light weight, low vibration, low noise, while waterproof, dustproof, anti-corrosion, energy saving, high performance, high efficiency, long service life.
The above are the advantages of aluminum alloy material used as motor body, of course, aluminum material also has its disadvantages, that is, high price, low hardness, more suitable for the device does not need to be very out of the place, such as motor cover, body.

The surface treatment of aluminum alloy motor housings is also very important. Surface treatment can improve the quality, corrosion resistance and aesthetics of the motor housing. Common surface treatment methods include anodizing, electrophoretic coating, spraying and so on. Among them, anodizing is the most commonly used method, which can form a layer of oxygen coating and improve the corrosion resistance and hardness of the motor housing. Electrophoretic coating and spraying are suitable for making colorful and beautiful motor shells.
FAQ
1. What is an aluminum die-cast motor body?
Aluminum die casting motor body is the motor body part wrapped around the motor’s outer shell, which is made of aluminum alloy through the die casting process. Die casting is a manufacturing method in which molten metal is injected into a mold and then solidified into a desired shape under high pressure, and this method allows for the mass production of the required motor body.
2. What are the advantages of aluminum die casting motor bodies?
Aluminum die casting motor body has the advantages of light weight, high strength, excellent thermal conductivity and good surface quality due to the use of aluminum alloy material. Aluminum motor body is produced by die-casting process, die-casting process can produce complex shapes and precise dimensions of aluminum parts, can be customized according to the shape of the motor design, including the design of the surface of the fin-like heat sinks. And the aluminum material is easy to process and can be widely produced.
3. What are the application areas of aluminum die casting motor bodies?
Aluminum die casting motor body has a wide range of applications, different types of motor shell can be used aluminum die casting shell, including industrial motors, household appliances, automotive parts and other fields. They are usually used as the external protection and support structure of the motor, playing the role of heat dissipation, protection.
4. What are the design considerations for aluminum die casting motor body?
When designing an aluminum die-cast motor body, you need to consider the strength of the body, heat dissipation performance, electromagnetic shielding and other factors. In addition, the appearance design of the body should also be considered to meet the actual application and market demand. According to different applications can also consider different surface treatment, such as painting, anodizing and so on.
5. What are the price factors for aluminum die-cast motor bodies?
The price of an aluminum die cast motor body is affected by a number of factors, including the price of the aluminum material, the manufacturing process, the size of the body, the quantity, and the quality requirements. You can send us your drawings and we will give you a quick quote.
6. What is the maintenance method for aluminum die cast motor bodies?
Maintaining an aluminum die casting motor body usually includes regularly inspecting surfaces for damage, cleaning impurities, and keeping cooling passages clear.
① The use environment of aluminum die-casting motor shell should always adhere to the dry, motor appearance should be kept clean, the air inlet should not be obstructed by dust, fibers and so on.
② when the motor of the thermal maintenance of continuous action, should identify the fault from the motor or overload or maintenance device setting value is too low, eliminate the fault before putting into operation.
③ Good lubrication should be ensured during the operation of the motor. General motor operation 5000 hours or so, that should be supplemented or replaced grease, found in operation bearing overheating or lubrication metamorphosis, hydraulic timely change grease. Replacement of grease, should remove the old lubricant, and gasoline to wash the bearings and bearing cover oil groove, and then ZL-3 lithium grease filling the cavity between the inner and outer rings of the bearing 1/2 to 2 pole, 2/3 to 468 pole.
④ When the life of the bearings ends, the vibration and noise of the motor operation will increase obviously, check the radial clearance of the bearings to reach the following values, then the bearings should be replaced.
⑤ When assembling the motor, it is OK to remove the rotor from either the shaft extension or non-extension end. If it is not necessary to remove the fan, it is more convenient to remove the rotor from the non-extended end. When removing the rotor from the stator, prevent damage to the stator windings or insulation.
When replacing the winding, it is necessary to note down the form, size and number of turns of the original winding, wire gauge, etc. When these data are lost, they should be obtained from the manufacturer. Changing the original design of the winding at will will often deteriorate the performance of a certain item or items of the motor, or even make it impossible to use.
