METAL ETCHING

Chemical etching on metal, such as stainless steel, aluminum, or brass, is commonly used to produce high-quality signage, industrial labels, and decorative elements. The process starts with applying a photoresist material to the metal surface, which is then exposed to light through a photographic mask to create the desired pattern. The unexposed areas are then chemically etched away, leaving behind a permanent, high-resolution design. The result is a durable, corrosion-resistant finish that retains its clarity and detail over time.

Typical applications of stainless steel chemical etching processing include: springs, bending, and diaphragms; Screens, filters, and sieves; Automotive interior; Heat exchanger plate; Bipolar fuel cell plates, etc.

Stainless steel etching is the process of processing stainless steel through chemical corrosion. The etched materials include austenitic stainless steel materials such as SUS304, SUS301, SUS316, SUS430, etc. The thickness of the stainless steel etching material is 0.03-2.0mm, and the accuracy can reach ± 0.01mm. Stainless steel etching has the advantages of smooth surface without burrs, flat edges, and vertical hole walls
