Ejector pins and moldsRound ejector pins and mold cores often have to be manufactured very precisely.
Typical machining process is grinding or turning. But for very small diameters lateral machining pressure is not possible. Besides wear of machining tools cannot be calculated exactly.
These problems are avoided by manufacturing on wire EDM equipped with rotating spindles. Besides, using our eroding equipment precision is increased significantly.
This process is applicable for nearly all holes in electrically conductive materials. The technology can also be used for high precise machining of outer outlines.
