Capabilities For Aluminum Die Casting Rotor Lamination

Aluminum die casting is a manufacturing process that involves injecting molten aluminum into a steel mold or die under high pressure. The aluminum solidifies within the die, and when the die is opened, the casting is ejected. The operation allows for the production of intricate and complex parts with high precision and repeatability.

This involves creating a 3D model of the motor rotor part using computer-aided design (CAD) software. Our design must take into account factors such as the part’s shape, size, and function, as well as any features.

Once the design is finalized, a mold or die is created. This is usually made of steel and consists of two halves that fit together to form the desired shape of the part. The mold is machined to the exact specifications of the part and is often made with features that allow for the injection of molten aluminum and the ejection of the casting.

This is typically done in a furnace, where the aluminum is heated to a temperature above its melting point. The exact temperature will depend on the specific alloy being used.

Once the aluminum is molten, it is injected into the mold under high pressure. This pressure helps to fill the mold completely and ensures that the casting will be free of defects. The aluminum solidifies rapidly within the mold, and when the mold is opened, the casting is ejected.

The casting is then allowed to cool and harden. Once cooled, it is removed from the mold and any excess material is trimmed off. The casting may also undergo additional finishing processes, such as burnishing, reaming, gate compression and/or removal, flash removal, and rotor outer diameter machining.

Benefits Of Aluminum Die Casting Motor Rotor Core Laminations


Aluminum is significantly lighter than copper or steel, making it an ideal choice for reducing the overall weight of the rotor. This can lead to improved energy efficiency and performance of the motor.

High Thermal Conductivity

Aluminum has excellent thermal conductivity, allowing for efficient heat dissipation from the rotor. This helps prevent overheating and prolongs the lifespan of the motor.

Corrosion Resistance

Aluminum has natural corrosion resistance, which can be further enhanced through surface treatments or coatings. This makes it suitable for use in a wide range of environments, including outdoor or humid conditions.


Aluminum die casting is a cost-effective manufacturing process, especially for high-volume production. The process allows for the production of intricate and complex shapes at relatively low costs.

Design Flexibility

Aluminum die casting allows for intricate designs and complex geometries to be easily replicated in the final product. This makes it possible to optimize the rotor's shape for improved performance and efficiency.

Electrical Conductivity

While not reaching copper's conductivity levels, aluminum still boasts decent electrical conductivity, rendering it suitable for various motor applications where performance is paramount.

Rotor Die Casted FAQS

Aluminum die casting is highly efficient compared to traditional casting methods because it requires less machining, reduces material waste, and enables complex designs. Compared to steel or copper rotors, aluminum rotors offer better thermal conductivity and are less susceptible to corrosion.

Aluminum die casting can produce various types of rotors, including squirrel cage rotors, wound rotor armatures, and magnetic rotors. These rotors are commonly used in electric motors for various applications, including automotive, aerospace, and industrial machinery.

Rotor aluminum die casting is commonly used in electric motors for applications such as electric vehicles, HVAC systems, industrial pumps, household appliances, and more. Its lightweight and high thermal conductivity properties make it particularly suitable for electric vehicles, where weight and cooling are critical factors.

Rotor die casting commonly uses aluminum ingot as a primary material due to its lightweight, strength, and excellent thermal conductivity. Aluminum-based alloys offer a balance of fluidity, pressure tightness, and corrosion resistance essential for rotor applications.

Squirrel cage rotor is one of the most important components of AC asynchronous motor. Pure aluminum guide bars are cast in each slot of the rotor. The guide bars are shorted with two end rings at both ends of the iron core to form a short-circuit winding, which is used to generate induced potential and then generate electromagnetic torque.
