pieces of substrate to be coated by electrolytic deposition

mechanical holding contacts (10) are applied to a workpiece (4) placed on a substrate (1) by a double actuation mechanism (11, 42) which closes the circle of contacts (10) before the down on the surface of the workpiece (4). A good uniform contact is guaranteed. The contacts (10) can exert up to the electric potential. Applying coatings by electrolysis.
