Ejector pins and molds
Round ejector pins and mold cores require precise manufacturing. At these tiny diameters, lateral machining pressure is not obtainable in the typical machining processes like grinding or turning, plus the wear of machining tools cannot be calculated exactly.
These problems are avoided by manufacturing on wire EDM equipped with rotating spindles. Precision is increased significantly by using our eroding equipment.
This process is applicable for nearly all holes in electrically conductive materials. This technology can also be used for the highly precise machining of outer outlines.
