This is an added Patent concerning Mold Manufacturing

        
           
This Patent was based on the fact that the Plastic Mold manufacturing was very
difficult and time consuming. Instead of using an EDM Sinker to pre-burn the
contour and then grinding the contour with a pneumatic pencil grinder (equipped  
with a cylindrical diamond pin) step by step larger, shooting samples on a plastic
molding machine after every change, running  Lab tests and then making other
changes until the regulation curve was acceptable >  I came up with the following

      idea: Wire EDM was very new -

                                              - however, changing the mold design in a manner that the
 profiled core or outer wall consisted of a replaceable disk insert and then burning
  the core profile with Wire EDM appears at first more complicated. For practical
reasons once a Wire EDM burned profile produces a fully functional regulation
curve the electronically saved machine data would allow building a multi insert
plastic injection mold very fast which translates into highly efficient production.
All mold inserts would be identical.
The Patent below claims this method and was accepted as an Invention.
