What is deep-drawing ?

Emprotec produces parts by cold forming  sheet metal.

This type of forming is carried out on a transfer press fitted with a drawing tool which consists of:

 

• A punch which is in the shape of the inside of the part to be produced

• A forming die which supports the material and gives it the outside shape

• A blank holder which presses the blank against the outside of the die to ensure a regular flow of metal

 

 

Emprotec has three transfer presses (60T to 100T). As these presses are fitted with lateral gripper rods, they can carry out all the drawing operations required for the end product. The entire drawing process can be carried out on only one press. The main advantages  are, first of all,  that the part is maintained in the best position between the different operations,     (compared to a line of presses) and secondly, that there is a high speed of output. These relatively high rates of production can lead to friction and heating of both parts and tooling, so a water-based oil spray is used to absorb  excess calories.
