ABSOLUTE teaches you the basics of stamping die terminology

1. Curling Curling is a stamping process that rolls the edge of the process part into a nearly closed circle. The axis of the curling circle is straight. 2. Flanging Flanging is a stamping process that rolls the upper edge of the hollow part into a nearly closed circle. 3. Drawing Drawing is a stamping process that changes the straight raw material or process part into a curved surface. The curved surface is mainly formed by the extension of the material at the bottom of the punch. 4. Stretch-bending Stretch-bending is a stamping process that realizes bending deformation under the combined action of tension and bending moment, so that the entire curved cross-section is subjected to tensile stress. 5. Bulging Bulging is a stamping process that expands hollow parts or tubular parts radially outward. Sectioning Sectioning is a stamping process that divides the forming process part into several parts. 6. Leveling Leveling is a stamping process that improves the flatness of local or overall flat parts. 7. Undulating forming It is a stamping process that relies on the extension of the material to form a local depression or convexity in the process part. The change in material thickness during undulation forming is unintentional, that is, a small change in thickness is naturally formed during the deformation process, not a design requirement. 8. Bending Bending is a stamping process that uses pressure to cause plastic deformation of the material, so that it is bent into a shape with a certain curvature and a certain angle. 9. Chiseling Chiseling is a blanking or punching process using a sharp-edged chiseling die. There is no lower die in chiseling, and the material under the material is just a flat plate. Most of the punched materials are non-metallic. 10. Deep hole punching Deep hole punching is a punching process when the hole diameter is equal to or less than the thickness of the punched material. 11. Blanking Blanking is a stamping process that separates the material along a closed contour. The separated material becomes a workpiece or process part, most of which are flat. 12. Shrinking Shrinking is a stamping process that pressurizes the open part of a hollow part or a tubular part to shrink it. 13. Shaping Shaping is a stamping process that relies on material flow to slightly change the shape and size of the process part to ensure the accuracy of the workpiece. 14. Trimming Trimming is a stamping process that cuts off a small amount of material along the outer or inner contour to improve the edge finish and verticality. The trimming process generally also improves dimensional accuracy. 15. Hole turning Hole turning is a stamping process that turns the material into a side flange around the inner hole. 16. Flanging Flanging is a stamping process that turns the material into a side short edge around the outer curve. 17. Drawing Drawing is a stamping process that turns a straight raw material or process part into a hollow part, or further changes the shape and size of a hollow part. During drawing, the hollow part is mainly formed by the material outside the bottom of the punch flowing into the die. 18. Continuous drawing Continuous drawing is a stamping method that uses the same die (continuous drawing die) to gradually form the required shape and size on a strip (coil) through multiple drawing. 19. Thinning and drawing Thinning and drawing is a drawing process that further changes the shape and size of the hollow process parts and intentionally thins the side walls. 20. Reverse drawing Reverse drawing is a drawing process that turns the inner wall of the hollow process parts outward. 21. Differential temperature drawing Differential temperature drawing is a drawing process that uses heating and cooling methods to make the temperature of the part to be deformed much higher than the temperature of the deformed part of the material, thereby increasing the degree of deformation. 22. Hydraulic drawing Hydraulic drawing is a drawing process that uses liquid in a rigid or flexible container to replace the punch or die to form a hollow part. 23. Beading Beading is a type of undulation forming. When the local undulation appears in the form of ribs, the corresponding undulation forming process is called beading.
