Process properties
(1) contour blanking die along the closed or open the material separation. Such as blanking die, punching die, cutting die, cutting die, trimming die, cutting die etc..
(2) bending die to blank or blank sheet along a straight line (curve) bending deformation, die workpiece to obtain a certain angle and shape.

(3) the drawing die is made of the blank sheet opening hollow, or hollow pieces of further changes to the shape and size of the mold.

(4) die rough or semi-finished workpiece is convex according to plan, direct copy the shape of the die forming material itselfgenerate only local plastic deformation of the mold. Such as bulging die, necking die expansion die forming die rolling, flanging die, plastic mold.

Process combination
(1) single process model in a press tour, only completed a die stamping process.
(2) there is only one working station of the compound die, in one stroke of the press, at the same time in the same station, two or more than two stamping processes are completed.

(3) level in the model (also known as the modulus of continuity in the feeding direction of rough, with two or more stations, in a press tour, on a different station successively completed two or two above the stamping process of mold.

Modulus of continuity (PDX), press in a punch stroke by ribbon stamping raw materials, in a pair of mould with several different positions at the same time to complete a plurality of stamping process of cold stamping die, dies every stamping completion time and material with the move away from a, until the product is finished.

Modulus of continuity in the stamping process of the material belt always to a direction of movement; mold material after take off to two or more than two direction of movement of the call level progressive die; material belt feeding material in the mold called automatic continuous mode; in a stamping production chain with different process of stamping die manipulator or other automated facilities, the mold or moving parts complete stamping parts processing rated mold called multi station die.
