Hot spraying

Hot spraying is an important process in the metalworking industry, which is used in particular for the production of precise and high-quality metal parts. This process, also known as metal injection molding, enables the production of complex shapes and components by melting and injecting molten metal into molds or dies.

The first step in hot spraying consists of melting the metal to be processed. This takes place in a melting furnace in which the metal is heated to the required temperature in order to convert it into a liquid state. Different metals and alloys can be used, depending on the specific requirements of the end product. Once the metal has melted, it is injected into the prepared mold under high pressure. This mold, also known as an injection mold or die, is precisely manufactured and reflects the desired end product. The pressure under which the metal is injected helps to ensure that the mold is filled completely and in detail.

A key advantage of hot spraying is its ability to reproduce complex geometries and fine details with high precision. This makes the process particularly attractive for the production of parts with tight tolerances and sophisticated designs. The resulting components have a good surface quality and often require minimal post-processing. After injection, the metal is cooled and solidified in the mold, resulting in the desired end product. The removed parts can then undergo further processes such as surface treatment, heat treatment or assembly to meet the final technical and aesthetic requirements.

Overall, hot spraying is a highly sophisticated process that is widely used in various industries, including automotive and aerospace, as well as in the manufacture of precision components. It offers an efficient and precise method of producing metallic components with a wide range of applications.
