    The first diaphragms are successfully produced in the forming mold. With a laser machine, the 0.15 mm stainless steel plate has been cut. The two diaphragms will be hold into the mold, with a water pressure of 85 Bar in a stainless steel envelope. With a air (nitrogen) pressure of 10 bar the diaphragm deforms into the right shape.
