Refining of metals: an overview of the industry
Refining of metals: precision and the correct management of different materials are essential. This industry uses different types of metal, from steel and aluminum to chrome. Used methods in the refining of metals include chrome plating, zinc plating, various coating techniques, electroplating, and powder coating. Within these techniques, in turn, there are different variants. The combination of the numerous finishing methods and the many materials creates a very complex industry, where precision and exact process-control are essential.
Precise controls and measurements are essential as soon as goods are received in the refining of metals. For example, the different metals and auxiliary materials are checked for their purity or technical properties. The need for continuous monitoring increases during the various phases of production. The electroplating process, for example, must be permanently monitored. This involves parameters such as acid and metal content. Likewise, a large proportion of the controls for quality assurance in the finishing of metals are carried out. For example, optical inspections are carried out, such as the inspection of appearance or color. Electronic systems are increasingly being used for this, which measure very precisely and detect even the smallest deviations. In further checks, the surface quality, layer thickness, or corrosion resistance are checked.
