Center hole
The punching center hole is a stamping process that forms a shallow concave center hole on the surface of the working piece, and the back material does not have a corresponding protrusion.

Jingchong
Fine punching is a kind of smooth punching. It uses the fine punching die with a toothed press board to make the entire cross section of the punching part completely or substantially clean.

Continuous mode
A continuous die is a die with two or more stations. The material is fed into the station one by one as the press travels, thereby gradually forming the die.

Single process mold
A single-step die is a die that only completes one step in one stroke of the press.

Combination die
Combining die is a general-purpose,adjustable complete set of punches that gradually form various punching parts according to geometrical elements (straight lines, angles, arcs, holes). The contour profile of a planar punching part generally requires several pairs of combination punches to be punched in stages.

Convex
The embossing is a stamping process in which the punch is pushed into one side of the process piece to force the material to flow into the opposite pit to form a protrusion.

Embossing
Embossing is a kind of stamping process that forces the local extrusion material to form a dimple pattern, a pattern, a text, or a symbol on the surface of the work piece. The back of the embossed surface does not correspond to dimples.

Forming
Forming is a general term for the stamping process that relies on material flow and does not rely on material separation to change the form and size of the process piece.

Clean cutting
Bright and clean stamping is a stamping process in which all or substantially all of the entire section is directly and smoothly cleaned without refurbishment. Twisting and twisting is a stamping process in which part of a flat or partially flat process piece is twisted at an angle with respect to another part.

crimping
Crimping is a stamping process in which the edge of a process piece is rolled into a nearly closed circle. The curled circular axis is linear.

Roll edge
The roll edge is a stamping process in which the upper edge of the hollow member is rolled into a nearly closed circle.

Draw
Drawing is a stamping process in which a straight wool or a process piece is changed into a curved shape, and the curved surface is mainly formed by the extension of the material located at the bottom of the punch.

Pull bend
Tensile bending is a stamping process in which the bending deformation is achieved under the combined action of the pulling force and the bending moment so that the entire bending cross section is subjected to tensile stress.

Bulging
Swelling is a stamping process that expands a hollow member or tube radially outward.

Cutting
Sectioning is a stamping process that divides the forming process into parts.

Leveling
Leveling is a stamping process that increases the flatness of a partially or entirely planar part.

Rising formation
The undulation forming is a stamping process that relies on the extension of the material to form a partial depression or projection in the process piece. The change of the material thickness in the undulation forming is not intended, that is, a small change in thickness is naturally formed during the deformation process, and is not a requirement of the design specification.

bending
Bending is a stamping process in which a material is plastically deformed by pressure so as to be bent into a shape having a certain curvature and a certain angle.

Chiseling
Chiseling is a blanking or punching process using a pointed cutting chisel. The chisel does not have a lower die. The pad under the material is just a flat plate. Most of the punched material is non-metal.

Deep hole punching
Deep hole punching is a punching process in which the hole diameter is equal to or smaller than the thickness of the material being punched.

Blanking
Blanking is a stamping process that separates material along a closed contour. The material being separated becomes a workpiece or a process piece, most of which is flat.

Shrink
Shrinkage is a stamping process that pressurizes the hollow member or tubular member to reduce its size.

Shaping
Reshaping is a stamping process that relies on the flow of materials, small changes in the shape and size of the process components, to ensure the accuracy of the workpiece.

Renovation
Renovation is a stamping process in which a small amount of material is cut along the profile or contour to improve the edge finish and verticality. The refurbishment process generally also improves the dimensional accuracy.

Turn hole
The hole is a stamping process that turns the material around the inner hole into side flanges.

Flange
Flanging is a stamping process in which the material is turned into a short lateral edge along the contour curve.

Deep drawing
Deep drawing is a stamping process in which straight fleece or process parts are changed into hollow parts, or hollow parts are further changed in shape and size. When deepened, the hollow member is mainly formed by flowing into the female mold by a material located outside the bottom of the punch.

Continuous deep drawing
Continuous deep drawing is a stamping method in which the desired shape and size are gradually formed by multiple drawing using the same auxiliary die (continuous drawing die) on the strip (roll stock).

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

Anti-deep
Reverse drawing is a deep drawing process in which the inner wall of a hollow process piece is everted.

Differential temperature
Differential temperature drawing is the use of heating, cooling means, so that the temperature of the material to be deformed is much higher than the temperature of the deformed part of the material, thereby increasing the degree of deformation of a deep drawing process.

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

Buckling
Buckling is a form of undulations. When the partial undulations appear as ribs, the corresponding undulating forming process is called pressing.
