Drawing process

The drawing process is a cold working process that transforms flat sheet metal into a three-dimensional component of varying constant thicknesses through the use of a die and primarily hydraulic presses.

Of the various cold sheet metal deformation technologies, the drawing process is the one that most requires long experience in the field, knowledge of metallurgy, and knowledge of dies and the stamping process. Therefore, a good and close-knit team of engineers and technicians is needed to make increasingly sophisticated products for increasingly demanding customers.

At Minifaber, the drawing process begins with a study and analysis using finite element software specifically for drawing. 

From this initial analysis, it becomes clear whether the part will be feasible and how many steps will be required. The study and simulation must take into account of all aspects involved in this process: the design of the object, the material and thickness, how the material is transformed at the metallurgical level during the various steps, the type of die and the lubrication.

Making the die requires great specialization in the selection of materials, fabrication, heat treatments, and coatings on its active parts.
Last, final testing is done with the necessary fine-tuning to make the process perform and obtains the desired finished parts.
