Two Kinds of Manufacturing Methods for Steel Wheels

Method 1: Section Steel or Hot Rolled Steel Plate Coiling

Bend section steel or steel plate into a circle, close up and weld, compress, expand, smooth the weld, re-compress and punch the valve hole.

Disadvantages: There are solder joints at the joints. The requirements for equipment processing capacity are not very high, but the requirements for welding technology are high.

Method 2: Hot Pressing Forming of Steel Plate

Steel plate is cut into a circular ring, heated in a heating furnace, and pressed into wheel rim by oil press through forming mold.

Advantage: No welding points. Production process and equipment are more advanced. Disadvantages: The equipment investment cost is high.
