1. Curling edge

Rolling edge is a stamping process that rolls the edges of process parts into a nearly closed circle. The axis of the curled circle is straight.

2. Rolling edge

Rolling edge is a stamping process that rolls the upper edge of a hollow part into a nearly closed circle.

3. Drawing and stretching

Drawing is a stamping process that transforms flat wool or process parts into curved shapes, which are mainly formed by the extension of materials located at the bottom of the convex mold.

4. Pull bend

Bending is a stamping process that achieves bending deformation under the combined action of tension and bending moment, causing the entire bending cross-section to be subjected to tensile stress.

5. Bulging shape

Bulging is a stamping process that expands hollow or tubular parts radially outward. Cutting is a stamping process that divides a formed part into several parts.

6. School leveling

Leveling is a stamping process that improves the flatness of local or overall planar parts. Undulating forming

7. Fluctuating forming

Fluctuating forming is a stamping process that relies on the extension of materials to form local depressions or protrusions in the process parts. The change in material thickness during undulating forming is unintentional, meaning that a small change in thickness is naturally formed during the deformation process and is not a requirement specified by the design.

8. Bending

Bending is a stamping process that uses pressure to cause plastic deformation of materials, resulting in a shape with a certain curvature and angle.

9. Chiseling and cutting

Chiseling is a cutting or punching process using a sharp edged chisel die. There is no bottom mold for chiseling and cutting, only a flat plate is placed under the material, and the majority of the material being punched is non-metallic.

10. Deep hole punching

Deep hole punching is the punching process when the aperture is equal to or less than the thickness of the material being punched.

11. Material dropping

Dropping is a stamping process that separates materials along a closed contour, and the separated materials become workpieces or process parts, most of which are flat.

12. Shrinking mouth

Shrinkage is a stamping process that applies pressure to the open area of a hollow or tubular component to reduce its size.

13. Plastic surgery

Plastic surgery is a stamping process that relies on material flow to change the shape and size of the workpiece in a small amount, in order to ensure the accuracy of the workpiece.

14. Renovation

Repair is a stamping process that involves cutting a small amount of material along the outer or inner contour to improve edge smoothness and perpendicularity. The repair process generally also improves dimensional accuracy.

15. Flip hole

Flipping is a stamping process that turns the material into a side standing flange around the inner hole

16. Flip up

Flanging is a stamping process that flips materials into side standing short edges along the contour curve.

17. Deep drawing

Deep drawing is a stamping process that transforms flat raw materials or process parts into hollow parts, or further changes the shape and size of hollow parts. The hollow part during deep drawing mainly relies on the material located outside the bottom of the convex mold flowing into the concave mold.

18. Continuous deep drawing

Continuous deep drawing is a stamping method that gradually forms the desired shape and size on a strip (roll) material through multiple deep draws using the same mold (continuous deep drawing die).

19. Thinning and deep drawing

Thinning and deep drawing is a deep drawing process that further changes the shape and size of hollow process parts, intentionally thinning the side walls.

20. Reverse deep drawing

Reverse drawing is a deep drawing process that turns the inner wall of a hollow workpiece outward.

21. Differential temperature deep drawing

Differential temperature deep drawing is a deep drawing process that uses heating and cooling methods to make the temperature of the material to be deformed much higher than that of the already deformed part, thereby increasing the degree of deformation.

22. Hydraulic deep drawing

Hydraulic deep drawing is a deep drawing process that uses liquid contained in rigid or flexible containers to replace convex or concave molds to form hollow parts.

23. Reinforcing bars

Compression reinforcement is a type of undulating forming. When local undulations appear in the form of ribs, the corresponding undulating forming process is called reinforcement pressing.
