chemical etching and tolerance If tight tolerances are a strict requirement for your product, Chemical Etching can be a good option, compared to traditional manufacturing processes. Tolerance typically seen on chemically etched features is only around +/- 10% of the parts' thickness. We deal with thicknesses of 25 µm to 2mm For metals 0.01 mm to 0.25 mm in thickness, the minimum standard etching tolerance is ±0.025 mm. For thicknesses above this (to a maximum of 1.5mm) the minimum standard etching tolerance is typically ±10% metal thickness. While traditional metal machining can achieve tighter tolerances, there are limitations Additional ½-etch applications are used to assist in precise repetitive non-marring distortion free product being bent or formed. Tolerances - Establishing exact tolerances in photochemical machining are hard to ascertain due to the fact the type of material used, size of the product, and yield requirements will affect the tolerance passable Standard etching tolerances. Tolerances are a key consideration in any design and with photo etching varies dependent on the material thickness. For materials between 0.025 mm and 0.250 mm the minimum standard tolerance achievable is ±0.025 mm and between 0.250 mm and 1.5 mm ±10 percent of the metal thickness
Chemical etching is a method of engraving that uses a high-pressure high-temperature chemical spray to remove material to create a permanent etched image in metal. A mask or resist is applied to the surface of the material and is selectively removed, exposing the metal, to create the desired image Generally speaking, photo chemical etched dimensional tolerances are ±10% of the metal thickness. If a part is made of 0.010″ thick stainless steel, then the general rule is that the dimensional tolerance of the parts' features is ± 0.001″ (or 10% of the material thickness.
