Embossing is a handcraft technique that has been used since antiquity. In the production of sculptures, sheets of metal are embossed freely, fitted onto a model or worked into a negative form. The advantages of embossing in comparison to other techniques lie in the saving of material and the reduction in weight. It is therefore especially suitable for large sculptures or in the case of valuable materials such as gold, silver, and bronze. For around 40 years, chromium steel has also been embossed.

The sheet metal to be embossed is worked on with a chasing hammer, and becomes larger at this point. If the material is plastically deformed in this way, the crystal structures of the metallic material harden and it becomes brittle. Through intermediate annealing and quenching in water in individual phases of the work process, the metal material is returned to its original, relaxed crystalline structure (recrystallization). As a result, the original elasticity of the material is restored and it can be embossed anew until the final form desired is achieved. Many small partial pieces are worked on, reassembled once again, and finally welded or riveted together to create the whole sculpture.

We offer embossing at the production site in Shanghai. The 1:1 models necessary for it are often produced in St.Gallen.
