caustic etch milling

  • Acid Etching Companies Services | IQS Directory

    Acid Etching. Acid etching, otherwise known as chemical milling or chemical etching, is a chemical process used by many industrial metal parts manufacturers to etch, cut or engrave very delicate or precise lines into metal. This process involves very little mechanical work, for it is an almost entirely chemical procedure.

    “Chemical etching (photo etching) is a photo-lithographic process whereby a phototool is used to block UV light from exposing the area of a sheet of metal which has first been cleaned and laminated with photoresist. The sheet is developed which washes away the unexposed photoresist leaving a very precise mask of hardened photoresist behind.
