WIRE & SINKER EDM SERVICES
Sinker EDM, Wire EDM, and In-House Electrode Manufacturing.
Mantz Automation offers Sinker EDM as well as Electrical Discharge Drilling and wire EDM machining, which is machining by use of an electrical current running through a precision wire. Unlike CNC machining, which uses a cutting tool to remove metal material, Electrical Discharge Machining (EDM) directs high-frequency electrical sparks from an electrode to vaporize electrically conductive metals. The type of EDM is known as sinker EDM, or die sink EDM.
Electrical Discharge Machining (EDM) is widely used in mold and die making because it works so well on hard materials like titanium and hardened tool steels, enables more complex shapes and designs than mechanical cutting machines can produce, and doesn’t put any mechanical force into the workpiece. The surface quality of finished molds also tends to be of higher quality with EDM than with mechanical cutting technologies.
Electrical Discharge Machining Services
Mantz Automation provides EDM solutions for electrically conductive metals, including sinker EDM, wire EDM, electrical discharge drilling, and in-house electrode manufacturing. EDM uses high-frequency electrical sparks to vaporize material without applying mechanical force, making it well suited for hard materials, molds, dies, and complex designs.
Sinker EDM
Also known as die-sink EDM, this process uses a shaped electrode and electrical discharges to remove material from electrically conductive metals. Sinker EDM is well suited for hard materials such as titanium and hardened tool steels, as well as complex mold and die geometries.
Wire EDM
Wire EDM uses a precision wire carrying an electrical current to machine electrically conductive metals. It is well suited for producing intricate profiles and complex shapes with high precision.
Electrical discharge drilling uses electrical discharges to create holes in electrically conductive metals. It complements Mantz Automation’s sinker EDM and wire EDM capabilities.
Electrode manufacturing produces carbon electrodes for EDM. Mantz Automation uses 5-axis carbon machines and a robotic pallet changer to run production fully automated for days at a time, with little to no human intervention.

Electrode Equipment
Mantz Automation has some of the newest technology on the market for carbon electrode manufacture. During the EDM burning process the electrodes wear down, so multiple are cut for each project. We utilize a robotic pallet changer that can keep our 5-axis carbon machines running fully automated for days at a time. This allows for precision manufacture with little to no human intervention, providing cost savings for our customers.

Frequently Asked Questions
What is electrical discharge machining (EDM)?
Electrical discharge machining, or EDM, uses high-frequency electrical sparks to vaporize electrically conductive metal. Unlike CNC machining, EDM does not rely on a traditional cutting tool and applies no mechanical force to the workpiece.
What is sinker EDM?
Sinker EDM, also called die-sink EDM, uses a shaped electrode to remove material from an electrically conductive workpiece. It is commonly used to create complex shapes, cavities, and features in molds and dies.
What is wire EDM?
Wire EDM uses a precision wire carrying an electrical current to machine electrically conductive metals. The process is well suited for producing detailed profiles and complex shapes.
What materials can EDM machine?
EDM can machine electrically conductive metals, including hard materials such as titanium and hardened tool steels. The material must be electrically conductive for the EDM process to work.
When is EDM a good alternative to CNC machining?
EDM is often a good choice for hard materials, intricate geometries, mold and die components, and applications where mechanical cutting forces could affect the workpiece. It can produce shapes that may be difficult to create with conventional machining methods.
Does EDM apply mechanical force to the workpiece?
No. EDM removes material through electrical discharges rather than physical contact between a cutting tool and the workpiece. This makes it useful for delicate, hard, or complex parts.
What EDM equipment does Mantz Automation have?
Mantz Automation’s current EDM equipment includes the Sodick AG100, Mitsubishi EA30E, Gantry Eagle 1400, Gantry Eagle 1200, and Mitsubishi MV 4800 wire EDM machine.
