The repeat­ably high dimen­sion­al accu­ra­cy and sur­face qual­i­ty made pos­si­ble by the Roed­ers tech­nol­o­gy com­plete­ly elim­i­nat­ed the need for the EDM process. The machines and an automa­tion con­cept from Roed­ers dras­ti­cal­ly reduced the num­ber of nec­es­sary pro­duc­tion steps: from 16 to just 4, with sig­nif­i­cant advan­tages in terms of effi­cien­cy, costs, and process reli­a­bil­i­ty.

Die casting mould

Die cast­ing moulds are com­plete­ly (rough­ing and fin­ish­ing) machined direct­ly in hard­ened steel. The Roed­ers tech­nol­o­gy reli­ably achieves a sur­face qual­i­ty and accu­ra­cy which makes rework unnec­es­sary, even at mould part­ing surfaces.
