Cold forming is specially adapted to the mass production because of the high speed of the process contributing also to a significant reduction of the price compare with other technologies. The high repeatability is another advantage which permits to guarantee very tight tolerances on most of the dimensions of a product.
Required features which cannot be obtained with a standard cold forming process can be achieved by using secondary operation such as thread roll, drilling, heat treatment, plating, metal finishing, deburring, polishing,…
Often, there is no waste with a cold heading process and the wire is less expensive than the bar used for machining.
In addition to material savings, the process allows to offer attractive prices compare with other technologies.
A production of 60 to 300 parts/minute per machine can be reached depending of the component and the material used.
In addition to the material savings, cold forming permits also to avoid lead in the alloys for example.
Parts coming off a forming press are extremely repeatable. Critical and close tolerances can still be achieved in high volumes with consistency and reliability throughout the production making sure that every piece follows the specifications.
Mechanical properties increase throughout the process giving higher tensile strength after the deformation. Besides, the use of raw material adapted for cold heading permit to make further shaping such as crimping for example.
Typically, the process leads to manufacture products with very good surface finish without machining or tool marks.
