Capability For Aluminum Die Casting
Aluminum die casting is a highly sophisticated manufacturing process in industry motors. We provide transform molten aluminum into intricate shapes services.
The process begins with creating a mold, often made from two hardened tool steel dies. Next, we melt high-quality aluminum alloys at controlled temperatures. A hydraulic or die casting machine injects Molten aluminum into the die cavity under high pressure.
Once the aluminum solidifies, our mold is opened, revealing a robust and precisely formed rotor. Then, we process further, such as trimming, deburring, and surface finishing.
We can manufacture various sizes of aluminum rotor cores and a largest outer diameter of up to 1250mm.
Squirrel Cage Rotor Design And Manufacturing
A squirrel cage rotor is a cylindrical arrangement of bars made from a conductive material, typically aluminum or copper, interconnected at each end by conducting rings. It consists of rotor lamination and a squirrel cage and is widely used in industry motors.
Aluminum Squirrel Cage Rotor
We provide two primary manufacturing technologies die-casting and fabricated bars, for producing aluminum squirrel cage rotors.
Die casting is a widely used manufacturing method. In this process, molten aluminum is injected into a mold under high pressure to create the desired shape. In actual production, rotor die casting saves significant production time and cost.
Fabricated bar technology involves assembling individual aluminum bars and end rings to create the rotor structure. The bars are typically stamped(such as compound stamping, rotary notching, and progressive stamping), cut, or otherwise shaped to the desired form before being interconnected. This method is often used for custom or low-volume applications.
die-cast copper rotor
Except for the aluminum die-cast rotor, we deliver die-cast copper rotor services with a keen focus on precision and quality.
In the die-cast copper rotor process, high-quality copper alloy is carefully melted and injected into precision-engineered molds, resulting in intricate rotor shapes that exhibit exceptional thermal conductivity and electrical performance.
Our state-of-the-art machinery and skilled technicians ensure that each die-cast copper rotor is manufactured with meticulous attention to detail, meeting the stringent standards of the industry.
The resulting rotors boast enhanced efficiency, reduced energy consumption, and improved heat dissipation capabilities, making them a preferred choice for automotive, industrial machinery, aerospace, and renewable energy.
Benefits of Die Casting Rotor Lamination
The benefits of aluminum die-casting rotors are numerous, making them popular for various industries and applications. Here are some critical advantages of utilizing rotors core in electric motors and generators.
Enhanced Efficiency
Aluminum’s high thermal conductivity allows for better heat dissipation, reducing energy losses due to overheating. This leads to improved motor efficiency and overall performance.
Lightweight Design
Aluminum is significantly lighter than other materials like copper, making aluminum die-casting rotors ideal for applications where weight reduction is essential.
Excellent Conductivity
Aluminum is a good conductor of electricity, ensuring efficient current flow and minimizing energy losses within the rotor.
Reduced Eddy Current
Eddy current losses are minimized due to the lower electrical resistivity of aluminum, resulting in further energy savings.
Cost-Efficiency
Aluminum is more cost-effective than other materials like copper, particularly in high-volume production.
Corrosion Resistance
Aluminum possesses natural corrosion resistance, extending the lifespan of the rotor and requiring less maintenance.
Custom Die Casting Electric Motor Squirrel Cage Rotor
We provide aluminum die-casting rotor laminations and squirrel cage rotor custom service. The versatility finds application across diverse industries. Our application areas include the automotive sector, industrial machinery, wind turbines, hydroelectric generators, aerospace, etc.
Quality Control For Aluminum Rotors
Many factors affect aluminum casting, such as the number of rotor slots, length, and outer diameter. Any tiny mistakes will cause unacceptable defects inside the casting. We employ a rigorous quality control process involving advanced methods to validate our products’ integrity, performance, and durability.
1
We utilize weighing as a fundamental inspection method. By precisely measuring the weight of our cast aluminum rotors, we can calculate the actual filling rate of aluminum material. However, the qualified aluminum filling rate does not guarantee the quality of the rotor conductive strip.
2
We employ an X-ray inspection system to meticulously check the porosity of the end rings in our aluminum die-casting rotor laminations. This non-destructive testing can identify even more minor defects and prevent pore defects in the end rings from harming the overall performance of the rotor.
