Flaming

Flame treatment is a surface treatment technique that is mainly used for processing metals, plastics and natural stone. The surface is treated with an open flame to remove unwanted residues such as grease, oil or dirt. This technique is also used to improve the adhesion of coatings, paints or adhesives.

The process works by briefly and intensively heating the surface, which burns off or chemically changes organic residues. Flame treatment can also change the surface structure by opening pores or creating rough structures that are advantageous for certain applications. Typical applications include the pre-treatment of plastics before painting, the cleaning of metals or the finishing of stone surfaces to create an anti-slip texture.

The process requires precision and control, as too high a temperature or too long an exposure time can damage the material surface. For this reason, special burners and control systems are used to ensure even and controlled flame exposure.
