cold forging

If in order to save manufacturing costs, no or minimal trimming is required on the forged parts, but a good overall surface finish must be ensured, cold forging can be selected.

Imprint

During the imprinting process, the relatively soft material to be processed needs to withstand extremely high pressure in a closed mold, so that a specific mark on the surface of the mold is reproduced on the flat surface of the material to be made into coins, medals and similar objects.

Impression processing usually uses a single-station die or a progressive die and can be regarded as a special type of die forging process in which the side surface is restricted.

Choosing the correct mold material mainly depends on the type, strength, thickness and shape of the material being processed. The main failure mechanisms include chipping, cracking, abrasive wear, adhesive wear and plastic deformation.

Cold heading

In the cold heading process, a cold heading die is used to hit a portion of the wire or bar blank one or more times to create a different profile or a larger cross-section than the original.

Choosing the right mold steel mainly depends on the type, strength, thickness and shape of the workpiece of the material being processed. The main failure mechanisms include cracking, abrasive wear, adhesive roughening and plastic deformation.

Tools

A cutlery is a special form of imprinting (see above), except that it is used to make tableware or the like and reproduce a specific clear mark on the surface of the product. To produce cutlery - cutlery - single-station molds are often used.

Choosing the correct mold steel mainly depends on the type, strength, thickness and shape of the workpiece material to be processed. The main failure mechanisms include cracking, abrasive wear, adhesive roughening and plastic deformation.

SDWST powder steel (such as PMX4 PMX5 and PMX8 PMX50) is particularly suitable for cold heading processes.
