Electrical Discharge Machining

Precision, from every single accurate spark

EDM is widely used in industries like aerospace, medical, automotive, and mold making.

Manufacturing of dies and molds for plastic injection molding and metal casting.

Producing precision parts for aerospace engines and medical implants.

Drilling fine holes in turbine blades.

Creating small, intricate parts for microelectronics.

What is EDM Machining ?

Wire EDM (Precision for Difficult Materials and Intricate Shapes): When dealing with challenging materials like hardened steel or intricate shapes not achievable with traditional tools, wire EDM comes into play. It utilizes a thin wire electrode to precisely cut conductive materials with minimal heat distortion.
