Some key industrial considerations around using the spin forming process to make rapid sheet metal prototype parts:

Tooling and Equipment:
Spin forming is typically done on a specialized CNC spin forming machine or a modified CNC lathe with the appropriate tooling.
The tooling includes a mandrel (spinning form tool) and a pressure roller that shapes the metal sheet as it rotates.
For prototyping, the tooling can be fabricated relatively quickly and cost-effectively, especially compared to the tooling required for stamping or deep drawing.

Material Considerations:
As mentioned earlier, soft, ductile materials like aluminum alloys (1100, 5052, 6061) are well-suited for spin forming prototypes.
Other materials like brass, copper, and some stainless steel alloys can also be spin formed, depending on their formability.
The material thickness is typically in the range of 0.5 mm to 3 mm for sheet metal prototyping.

Part Geometry:
Spin forming excels at producing rotationally symmetric or simple non-circular parts, such as tapered, elliptical, or D-shaped profiles.
More complex geometries with significant variations in cross-section may be challenging and may require additional forming steps.

Production Rates and Turnaround:
Spin forming is generally a faster process compared to other metal forming techniques, allowing for rapid prototyping.
Prototype parts can often be produced in a matter of hours or days, depending on the part complexity and the availability of the spin forming equipment.

Surface Finish and Dimensional Accuracy:
Spin formed prototypes can achieve good surface finish, often requiring minimal post-processing.
Dimensional accuracy is generally within±0.5 mm, depending on the part size and complexity.

Cost and Scalability:
Spin forming is a relatively low-cost prototyping method, especially for small to medium-sized batches.
The process can be easily scaled up for low-volume production, if needed, by using higher-capacity spin forming equipment.
Applications:

Spin formed prototype parts are commonly found in industries like automotive, aerospace, appliances, and consumer electronics, where rotationally symmetric or simple non-circular shapes are required.

Overall, the spin forming process offers a flexible, cost-effective, and rapid solution for producing sheet metal prototype parts, making it a valuable tool in the industrial prototyping toolkit.
