Hardware stamping parts - what are the processes involved in the stamping process

Metal stamping parts are used in a wide range of applications. Due to their high processing accuracy, fast efficiency and controllable cost, the stamping process is chosen by most industries and products.

1. Curling

Crimping is a stamping process that rolls the edge of the workpiece into a nearly closed circle. The axis of the curled circle is straight.

2. Curling edge

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

3. Stretching

Drawing is a stamping process that turns straight wool or process parts into a curved surface. The curved surface is mainly formed by the extension of the material at the bottom of the punch.

4.Bending

Stretch bending is a stamping process in which bending deformation is achieved under the combined action of tension and bending moment, so that the entire bending cross section is subjected to tensile stress.

5. Bulging

Bulging is a stamping process that expands hollow or tubular parts radially outward. Sectioning Sectioning is a stamping process that divides the forming process part into several pieces.

6. Leveling

Leveling is a stamping process that improves the straightness of partial or overall flat parts. undulating shape

7. Relief forming is a stamping process that relies on the extension of materials to form local depressions or bulges in the workpiece. The change in material thickness during relief forming is unintentional, that is, a small change in thickness is naturally formed during the deformation process and is not a specified design requirement.

8.Bend

Bending is a stamping process that uses pressure to plastically deform the material and bend it into a shape with a certain curvature and angle.

9. Chiseling

Chiseling is a blanking or punching process using a sharp-edged chisel die. There is no lower die for chisel cutting, only a flat plate is placed under the material, and 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 smaller than the thickness of the material being punched.

11.Blanking

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

12. Shrink your mouth

Shrinking is a stamping process that pressurizes the open part of a hollow or tubular part to shrink it.

13.Plastic surgery

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

14.Renovation

Trimming is a stamping process that removes small amounts of material along the outer or inner contours to improve edge finish and verticality. The refurbishing process generally also improves dimensional accuracy.

15 holes

Turning is a stamping process that turns the material into a side flange around the inner hole.

16.Flange

Flanging is a stamping process that turns the material into short sides along the contour curve.

17.Deep drawing

Deep drawing is a stamping process that turns straight wool or process parts into hollow parts, or further changes the shape and size of hollow parts. During deep drawing, the hollow part is mainly formed by the material located outside the bottom of the punch mold flowing into the concave mold.

18. Continuous deep drawing

Continuous drawing is a stamping method that uses the same mold (continuous drawing die) to gradually form the required shape and size on the strip (coil material) through multiple drawings. 19. Thinning and deep drawing

Thinning and drawing is a drawing process that further changes the shape and size of the hollow process piece and intentionally thins the side wall.

20.Reverse drawing

Reverse drawing is a drawing process that turns the inner wall of a hollow process piece 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, thereby increasing the degree of deformation.

22.Hydraulic deep drawing

Hydraulic drawing is a drawing process that uses liquid contained in a rigid or flexible container instead of a punch or die to form a hollow part.

23. Pressure ribs

The beading of metal stamping parts is a kind of undulation forming. When local undulations appear in the form of ribs, the corresponding undulation forming process is called rib pressing.
