Mold Structure & Design Description

Gate electrodes are used during EDM machining to shape gate entrances, runner connections, and flow-sensitive areas within injection mold cavities. The electrode geometry directly affects melt flow balance, gate appearance, and mold consistency. Precision-designed gate electrodes help minimize EDM defects, ensure uniform cavity formation, and support stable mold performance during long production cycles.
