Chemical etching costs would be the sum of a number of elements, metal and photoresist, labour (including engineering), technical costs and machine time; not forgetting expenses which comprise of chemistries, water, strength and waste treatment, as well as the usual service and administration functions. Raw material costs are likely to vary drastically in price. Needless to say, standard levels of stainless-steel, dime silver and brass are going to be significantly less expensive than exotic metals, such as be (symbol), molybdenum, titanium and condition memory metals. Etching consists of a blend of procedures, which mainly are made up of sheet sizing and tooling, cleaning, photoresist lamination, publishing, developing, picture decoration and stripping. Virtually every process has a labour content, creating this a substantial component of the overall cost. The work is virtually the same whatever the sheet size and for this reason, sheet dimensions are an important factor in imag...
