Providing Outstanding Wire EDM Discharge Machining & Services for Over 10 Years
At Elimold we started using wire EDM technology in the early 2010 to make the tooling and dies for our other manufacturing processes. Several years later, we expanded our EDM department to include full production capabilities for customer projects.
Today, we utilize a fleet of state-of-the-art Mitsubishi wire EDM machines to produce tooling and dies and custom two-dimensional metal parts and components for our customers. We continuously upgrade our wire EDM technology to ensure that we have the most advanced capabilities available.
Most of our EDM systems are used for customer part production, with a small number dedicated to tool and die making. However, we can scale our production capabilities as needed, and transition some or all our tool and die EDM processes to part production to deliver high-volume part orders as quickly and efficiently as possible. This flexibility is advantageous for us and for our customers.
We specialize in cutting microkeratome Lasik blades for medical use in very high quantities. Each of the Lasik blades goes through an on-site, 100% optical inspection using our OGP Smartscope, as well as an ultrasonic cleaning process. Elimold’s EDM services have been applied in medical, aerospace, defense, laser technology, electronics, jewelry, athletic industry applications, and many more. Whether your project utilizes wire EDM or sinker EDM machines, we can guarantee tight tolerances for the smallest to the largest of parts, in any quantity from one to the millions. No industry or application is out of our range, and no project is too big or too small. As a full-service EDM job shop, Elimold can do it all!
Types of EDM
There are three types of EDM cutting processes. These include:
- Die sinking EDM – The die sinking EDM process is the conventional electric discharge machining process. Die sinking EDM uses a die to create complex features. Die sinking EDM involves the use of a die, which is an electrode made out of copper or graphite and is used to shape the metal. An electric current is passed through the die to erode the metal away in a controlled manner. The die is then gradually moved in order to create the desired shape while the material excess is flushed away in the dielectric fluid. This process is particularly useful for machining complex shapes that are difficult to create using conventional machining techniques and other EDM methods.
- Wire cut EDM – Something like a wire cutting through cheese, the wire EDM machining process relies on a thin wire that cuts through metal via spark erosion. Wire EDM works by using a thin wire to create sparks between the wire and the material being cut. The sparks erode the material and create a precise cut. This process can be used to cut complex shapes and intricate patterns. In many cases wire EDM is faster and more accurate than traditional machining methods, making it cost-effective for certain shapes. When two axis of motion are involved it results in parts with vertical edges and two-dimensional shapes. EDM wire cutting machines are capable of creating complex shapes with incredibly tight tolerances. Materials that can be cut by wire EDM include all conductive metals such as titanium, steel, aluminum, and brass.
- Hole drilling EDM – Hole drilling EDM is a machining process that uses electrical discharges to create holes in metals. The process is similar to conventional drilling, but instead of using a drill bit, an electrode is used to create sparks between the workpiece and electrode. The spark discharges melt or vaporize tiny amounts of the workpiece, which can then be further machined to the required size and shape. Hole drilling EDM is an extremely accurate and precise method of machining and can be used to create holes in very hard materials. Hole drilling EDM can create small and deep cavities in materials.
Advantages of Wire EDM
Compared to other precision metal cutting processes, wire EDM has many advantages:
- No custom tooling required – delivery times are short
- No cutting forces present – virtually no burrs generated
- Workpiece material hardness does not affect cutting speed
- Improved surface finishes – no additional finishing or polishing needed
- Tools & metal parts are machined after heat treatment – dimensional accuracy is maintained
- Highly repeatable with no deformation
- Ability to stack, string & nest multiple parts
- Ideal for delicate & complex parts
- Tight tolerances & precise fits
- Small corners & radii
- Narrow slots & thin walls
Wire EDM cutting is ideal when the workpiece material doesn’t lend itself to conventional machining, for example hardened tool steels and exotic materials.
