Metal spinning is a symmetric rotational forming process for sheet metal that is widely used in a variety of industries, including furniture, lighting, tableware, aerospace and more.
Cost: The cost of molds is low, but the unit cost is average.
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 and medium batches.
Quality: The surface quality of metal spinning products largely depends on the operator's skill and production speed.
Speed: Metal spinning has a moderate production speed, which mainly depends on the size, complexity and thickness of the sheet being processed.
Applicable materials
Suitable for soft metal plates such as stainless steel, brass, copper, aluminum, titanium, etc.
Design considerations
Limitations: Metal spinning is only suitable for producing rotationally symmetrical parts, with thin-shell hemispherical metal parts being the most ideal shape.
Size restrictions: The inner diameter of parts formed by metal wiring must be kept within 2.5 m.
Spinning process
Step 1: Fix the cut circular metal plate into the machine chuck
Step 2: The mandrel rotates the circular metal plate at high speed, while the tool with the wheel begins to press against the metal surface until the metal plate adapts 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.
