Exploring Metal Spinning: Essential Steps and Techniques

Metal spinning is a symmetrical rotational forming process for sheet metal that is widely used in a variety of industries, including furniture, lamps, tableware, aerospace, and more.

Metal spinning

Cost: The cost of molds is low, but the unit cost is medium.

Typical Products: Metal spinning is commonly used to produce products such as furniture, lamps, aerospace components, transportation equipment, tableware, jewelry, and more.

Suitable Batch Size: Metal spinning is best suited for small to medium batches.

Quality: The surface quality of metal spinning products is largely dependent on the skill and production speed of the operator.

Speed: Metal spinning has a moderate production speed, which mainly depends on the size, complexity, and thickness of the sheet metal being processed.

Applicable materials

Suitable for mild metal plates, such as stainless steel, brass, copper, aluminum, titanium, etc.

Applicable materials

Design considerations

Limitations: Metal spinning is only suitable for producing rotationally symmetrical parts, with hemispherical thin shell metal parts being the most ideal shape.

Size Constraints: The internal diameter of parts formed through metal spinning should be kept within 2.5m.

Spinning Process

Step 1: Fix the cut circular metal plate on the machine mandrel

Step 2: The mandrel rotates the circular metal plate at high speed, while the tool with the wheel begins pressing against the metal surface until the metal plate conforms to the inner wall of the mold.

Step 3: Once the molding process is complete, the mandrel is removed and the top and bottom of the part are trimmed for demolding.
