What is Cold Forming?

Cold Forming is a high speed manufacturing process that relies on metal flow due to applied pressure as opposed to traditional metal cutting. During the process wire is fed into the forming machine, cropped to length and then formed either in a single heading station or progressively in each subsequent heading station. During Cold Forming the load must be below the tensile strength, but above the yield strength of the material.

In Cold Forming the mechanical properties of the final component are directly influenced by the metallurgical properties of the raw material. So a lot goes into the selection of the raw material for cold formed components. In a nutshell the name says Cold Heading Quality (CHQ) raw material, but a lot of metallurgical aspects are to be considered while manufacturing and choosing the CHQ wires and slugs.

Another important key to precision Cold Forming is the design and manufacture of the cold forming tools.

Why Cold Forming ?

	Reduced material wastage
	Better strength of the part being cold formed due to better, undisrupted grain flow
	Better surface finish
	High rate of production
	Better economy of parts
	Wide range of material options:
			Low and medium carbon Steel
			Alloy Steels
			Stainless Steel
			Non ferrous material like copper, brass, etc.

All the above reasons transforms into generating a very cost effective solutions, especially for long production run.
