Pressing

When volumes become too large to produce efficiently on a press brake, forming with a press is the best option. With the right tools, we can even combine cutting and bending operations in a single production process.

Designing the appropriate tools for press operations is a complex task and is carried out by our own engineers. Based on their drawings and files, the components of the tools (also called tooling) are manufactured and assembled in our tool workshop. Once the first test products have been measured and approved, the tool is ready for full production.

Depending on the shape of the final product, the material, and the batch size, the most effective and efficient press is selected.

Deep drawing is a technique in which a metal sheet is transformed under mechanical pressure through plastic deformation into a seamless three-dimensional shape.

Of course, it is not intended that the material tears or wrinkles during the forming process. Therefore, the material must have sufficient “elastic properties.” Common metals used include aluminum, stainless steel (SS), steel, copper, brass, and others. When extreme deformations are required to produce the product, special metal types are needed.

It is also important that the surface is well-lubricated during the drawing process. The material is pulled over the edges of the die with great force. Lubrication prevents the die and punch from wearing out unnecessarily fast or the material from tearing or sticking to the die. For large deformations, it may also be necessary to perform multiple “draws” and apply heat treatments to “reset” the material.

The necessary tools for deep drawing are designed by our engineers and manufactured and maintained in our tool workshop. In deep drawing, a die is used that has the shape of the product to be manufactured, and a punch that has a complementary shape that fits into the die.
