Stainless steel nameplate etching equipment

Stainless steel nameplate etching equipment

Stainless steel etching is a process that selectively dissolves metal surfaces through a chemical solution. The process utilises a mixture of ferric chloride or nitric acid in a redox reaction with the metal. Exposed areas of the material are gradually eroded to form a predetermined pattern. The depth of processing is determined by the concentration of the solution and the immersion time.
