Plain Steel Weld 8mm Length Zinc Plating weld Bolt Cold Heading

Steel Weld Bolt

Description

Bolt manufacturing is mainly based on the principle of metal plastic deformation, using the die installed on the cold upsetting machine.

to move at a certain speed under the action of considerable unit extrusion force, so that the metal blank will produce plastic deformation in the die cavity, so as to become the required shape, size and parts with certain mechanical properties.

Cold heading process:
Cold heading belongs to bulk plastic forming at room temperature. The main deformation modes are upsetting, forward extrusion, backward extrusion, upsetting extrusion compound, trimming and so on.
Cold heading technology has the advantages of high efficiency and low cost.
