Graphite Mold Machining for Injection Molds: Application of Graphite Machining System in Precision Mold Manufacturing

Leave a Comment / Cutting Tools / By

We once solved a classic challenge for a client in the precision injection mold sector. They needed complex graphite electrodes for automotive electronic components. The project demanded high cavity consistency after EDM and a much faster production cycle. However, shop-floor graphite machining is never as simple as entering theoretical CAM parameters. Tool wear, graphite dust
