‍Cold forming and machining of Gardette bars

Cold drawing is a manufacturing process used in the metallurgical industry to produce metal bars and profiles. The main aim of cold drawing is to reduce the dimensions of a material to give it a precise, well-defined shape.

To get from raw material to a drawn steel bar, our process follows several steps:

  • First, we reduce the cross-section of the raw material by making a silk (i.e. reducing the end of the raw material).
  • Then we pass it through a die.
  • Finally, the stretching machine, known as a cold-drawing bench, pulls the material with the help of carts, thus achieving reduced dimensions with enhanced dimensional accuracy and mechanical characteristics.

How cold-drawing works

Cold drawing is in fact only the last stage in the production of drawn steel and bars.

Cold drawing, a fascinating process :

  • Carts pull the raw material through a narrow die,
  • It is then straightened using a succession of pebbles.
  • It is then sheared to the desired length.

This stretching process reduces the size of the material while giving it a precise shape. But that's not all! It also improves the material's strength and quality, offering optimum mechanical properties and increased resistance.

Our bars and profiles range from 3 to 4 meters, and we also offer cold-drawn coils.

By combining these different drawing processes, we are able to obtain solid products in the following forms:

  • In square, round or flat bars, with exemplary mechanical precision.
  • Made of metal profiles without removing any material.
  • In drawn coils that offer excellent performance on small dimensions.

Our cold-rolling, drawing and heat-treatment equipment enables us to manufacture a wide variety of standard (flat, square, hexagonal) and special profiles to drawing in a wide range of steel grades:

  • Carbon steels (C22, C45...)
  • Low-alloy steels (42CrMo4, 16NiCr6...)
  • Tool steels (90MnV8, 100Cr6...)
  • Stainless steel (304, 304L, 316Ti...)

What is cold rolling?

Cold rolling is a manufacturing process involving the deformation of raw materials, often combined with cold drawing. This deformation is made possible by continuous compression between two counter-rotating rolls (rotating in opposite directions) known as "rolling mills".

The metal is compressed and crushed, increasing its elasticity and hardness.

It is during the cold rolling process that the metal's mechanical properties change.

The cold rolling process enlarges the zone of elastic deformation, thereby increasing the material's yield strength without altering its breaking strength.

Cold rolling is mainly used for square sections such as keyed steels. It transforms a bar into a particularly thin metal coil.
