The image of the part to be manufactured is photographically transferred on to a metal plate and the unwanted Metal is removed by using a chemical etchant.

The finished product is thus produced chemically so that its mechanical characteristics remain unchanged and the part is ready for use without any additional treatment.

The parts produced by photo chemical machining are similar to thin gauge stampings and can be made from sheet or strip of almost any metal or its alloys, of any temper right from pre-hardened to dead soft and in thickness from 0.05mm min to 0.7 mm max.
