Iron drawing

The iron drawing process has distinctive features related to the specific properties of this material. 

The key points are as follows:

1. Strength and toughness of the material 
Ferrous materials can be subjected to drawing. However, alloys suitable for drawing must have a very low percentage of carbon to improve plastic reserve and percentage elongation. They are therefore malleable ferrous materials.

2. Types of ferrous material for drawing 
There are different grades of ferrous materials that are suitable for deep drawing, from moderately suitable to fully suitable for deep drawing. Deep drawing ability is inversely related to the mechanical strength of the material and directly related to percentage elongation. Forces and pressures must be adjusted for each material, as well as the correct choice of lubricant.

3. Finishing the active parts of the dies 
To allow the material to be deep-drawn to slide well and prevent breakage, wear or seizure, the active parts of the dies must be polished as much as possible and coated with PVD treatments to reduce the coefficient of friction.

4. Post-drawing treatments 
Iron often requires subsequent treatments, such as coating or galvanizing, to protect it from corrosion. The quality of the drawing directly affects the effectiveness of these treatments, so process precision is critical.

5. Versatility for industrial applications 
Iron drawing is widely used to produce structural and mechanical components due to the strength of the material.

6. Die design 
Dies for drawing ferrous materials must be designed to prevent defects such as wrinkling, breaking, excessive thinning and necking on drawn parts. For this reason, the right choice of die steels, polishing, heat treatments and PVD coatings are important, as is considering the blank holder forces and lubrication during the process.

In summary, the iron drawing process requires advanced equipment, precise fabrication techniques, and in-depth knowledge of the material to ensure high-quality, durable components that are ready for a range of industrial applications.
