Places and Sectors Where Wheel Molds Are Used

Types of Steel and Aluminum Wheel Molds

Wheel molds can be classified into various types according to the production method and intended use.

Cast Wheel Molds:

• Gravity Casting Molds: Molten metal is poured into the mold by gravity, especially used in aluminum wheel production.
• Low Pressure Casting Molds: Metal is injected into the mold under low pressure, providing better surface quality and strength.
• High Pressure Casting Molds: Metal is injected into the mold under high pressure, ideal for mass production and precise tolerances.

Forged Wheel Molds:

• Cold Forging Molds: Metal is shaped under high pressure at room temperature, providing high strength and lightness.
• Hot Forging Molds: Heated metal is shaped under high pressure, producing more complex shapes.

Pressed Wheel Molds:

• Hot Press Molds: Heated metal is pressed, generally used in steel wheel production.
• Cold Press Molds: Metal is pressed without heating, suitable for simple and flat wheel designs.

Rotational Casting Wheel Molds: Molten metal is poured into a rotating mold, producing highly precise and balanced wheels.

Extrusion Wheel Molds: Metal is extruded through the mold under high pressure, producing long and continuous wheel profiles, especially used in aluminum wheels.

3D Printed Wheel Molds: Produced with 3D printers, providing flexibility in prototype and special designs.

Each type of wheel mold is optimized for specific production processes and wheel design requirements. The correct mold selection is critical for the performance, durability, and aesthetics of the wheel.
