Metal strips of brass or silver are clamped on various stamping machines – parts are pressed. Various shapes, like springs / brackets, are punched out of the strip material, then shaped into forms. Furthermore crystal stones are also set in the machines in some cases.
When assembling the studs, the silver pins are connected to the silver shell. This is done with a specially developed tool. Various parts are cut to length (wires, brass chains, rubber bands).
New patterns are created: sample plate (silicone). Parts are placed on silicone plates and pressed, then removed again.
The cavities of the recesses on the underside of the plate are filled with silicone. White plates are harder and are used for larger parts, otherwise the material would flow out when spinning due to the flying force. Pink plates are used for parts with rhinestones. When all recesses have been 'excavated', large adjustment knobs are pressed into the top of the plate. Small adjustment knobs are pressed between the parts to keep the rubber plate more stable
pieces from casting are cleaned and prepared for soldering or plating.
Wax casting
In the wax casting department the silver articles are casted in the wax to start the lost wax process. The single casted wax pieces are set on a wax tree for final casting
different metal baths are used for galvanic plating
