Once the aluminium is melted, it is pressed into moulds, or more precisely ingot moulds, to create the basic structure of the rim. During the casting process, the mould is kept at a specific temperature to ensure a homogeneous structure.This is carried out by the production assistants at the smelting station and the foundry. They ensure the melting process, the transport of the liquid aluminium to the casting machines, and the constant filling of the same.
Manual work is essential
After casting, the first detailed processing of the so-called preform is done to remove excess material. Here, advanced machinery and technologies, as well as good old manual work, are used to ensure absolute precision. The surface is smoothed and checked for irregularities. Subsequently, three more steps are necessary. This is carried out by the production assistants of the X-ray, mechanical processing, and burnishing departments. Constant quality control is one of the greatest denominators of the respective departments.
