Die Sinking

Die Sinking EDM Solutions from Erodex

Erodex is a leading UK supplier of die sinking EDM products and solutions, supporting manufacturers in the tool and die, aerospace, automotive, and medical sectors. Whether you’re machining complex cavities, sharp corners, or high-tolerance moulds, our die sinking (or sinker EDM) solutions offer the precision, efficiency, and reliability you need.

With over five decades of experience in Electrical Discharge Machining (EDM), Erodex provides electrodes, consumables, and technical support to keep your sinker EDM operations performing at their best.

What is Die Sinking?

Die sinking, also known as sinker EDM or cavity-type EDM, is a process that uses a shaped electrode and controlled electric discharges to remove material from a workpiece. The electrode—typically made of graphite or copper—does not contact the workpiece directly but instead sparks across a gap, gradually eroding material to form intricate shapes or internal cavities.

This method is perfect for machining hard materials, producing complex geometries, and working within tight tolerances—especially in mould-making, stamping dies, and aerospace tooling.

Key Benefits of Die Sinking EDM

✔ No mechanical force – Ideal for fragile or hard-to-machine parts

✔ Precision cavity creation – Sharp internal corners and fine details

✔ Excellent surface finishes – Reduces the need for secondary processes

✔ Works on hardened materials – Including tool steel, titanium, and carbide

✔ Reproducible results – Great for batch work and mould replication
