Production of heads and bottoms through cold forming process.
100% made in Germany.

Slawinski heads and bottoms are produced in a cold forming process. At our production site in Siegen-Weidenau, we produce heads and bottoms with diameters of up to 5,400 mm and wall thicknesses of 30 mm, through dishing and flanging forming processes.

At our Bad Laasphe factory, heads and bottoms with diameters of up to 3,100 mm and wall thicknesses of 12 mm are shaped using the spinning forming process. All heads and bottoms can be subjected to heat treatment after cold forming in accordance with the production code.
