Deep drawing

Frequently asked questions about deep drawing

How do we know the maximum deep drawing limit?

To know the maximum depth that a material can be deep-drawn, is usually performed a deep drawability test. The purpose of the test is to determine the degree of drawability of the metal sheet. For this, a XNUMX cm x XNUMX cm square sample and a rounded-tip piston are usually used.

The starting point is the point at which the tip of the piston makes contact with the plate. Then constant pressure is applied until the plate begins to crack. At this point, the distance the piston has advanced is then measured. This distance gives us the measurement of the embutibility of the material. 

This test is common when working with new materials of different alloys. 

 

What type of pieces are made in deep drawing?

To get an idea, you could make a bathtub. Or a large dimensions pot. 

Deep drawing parts have more difficulty than stamping parts.

The materials that allow this type of deep drawing must be carefully selected.

How are deep drawing presses?
 

They are bigger than those of stamping because they need a longer path.

What is the presser used for?

The pressers prevent or control the movement of the piece while deep drawing.

They are essential when working with thin pieces. Or also when deep drawing or large diameter.

Thanks to the pressers, wrinkles or folds in the deep-drawn material can be avoided.

They are of a fixed, flat or slightly inclined type. 

There are also pressure or brake pressers that are used when it is intended to stretch the sheet to reduce its thickness. 

Can deep drawing be made with aluminum sheet?

It is possible, and in fact it is done. Although it has different degrees of difficulty. Aluminum is easier to crack than other materials.  

How is the excess material from the deep drawing cut out?

It will depend on the part and the process, but one option is to use a 3d laser. Thus the cut is clean and the end result is optimal.

The use of these 3d lasers in the metal 4.0 industry is more and more frequent.

The use of robotic arms is also imposing in this industry 4.0, either for welding or for cutting.
