Both spinning forming and deep drawing can shape the sheet metal, with specific differences and advantages as follows: 1. Principle difference: Spinning forming is controlled by the path of the cutting wheel to control the flow and deformation of the sheet metal, while the deep drawing controls the flow of the sheet metal through the combination of convex and concave molds. 2. Mold cost difference: The deep drawing mold cost is usually 3-6 times that of metal spinning, and the manufacturing cycle of spinning molds is also shorter. 3. Material difference: The thinning rate of spinning is usually about 30%, while that of deep drawing is about 10%. Deep drawing requires about 5-10mm of edge pressing material, which requires a higher material cost. 4. Production speed： With deep drawing or stamping mold, the production speed is much faster than metal spinning. Metal spinning’ speed for one part is relatively slow. 5. Product difference: In terms of the surface, the spinning marks are distributed in a circular pattern, while the stretching marks are distributed in a vertical line; In terms of strength, the strength of spun products is much better than that of stamping.
