Photo Chemical Milling

Photo chemical milling is also referred to as photo chemical machining or photo etching. In this process two-dimensional parts are produced from thin metal sheets or foils with very precise and filigree perforations or one and two-sided indentations by masking and etching.

Thanks to the chemical metalworking the tooling costs otherwise required can be omitted. In addition, the material is neither thermally nor mechanically stressed.

Since the late 90s, SCHMID is well-established in the field of photochemical milling and since then has worked together with renowned customers like Braun, the manufacturer of electric shavers who uses SCHMID systems for the production of shear blades for electric shavers. There is a wide range of applications: A Swiss luxury watch manufacturer utilizes SCHMID system for inscriptions and deep etching of his high-quality watch cases. A German automotive supplier produces loudspeaker grilles made of stainless steel for luxury passenger cars. More examples can be found in medical technology or mechanical engineering.
