At Wisconsin Metal Parts, we provide Wire EDM (Electrical Discharge Machining) services for high-precision components with intricate geometries requiring tight tolerances. We utilize this process on tool and die components, production parts and detail-oriented projects that require minimal finishing. Our in-house wire EDM machining capabilities support everything from prototype development to production runs, ensuring accuracy, repeatability, and consistent part quality. Our technology is set up to run 24/7, getting parts and components into your hands faster.
Our wire EDM services are designed to handle a wide range of part requirements, from intricate prototypes to production-ready components. We are specialists in building both fine blank tooling and difficult-to-make parts and components. Our team excels at accuracy and repeatability amongst both high and low volumes. Some of our more technical capabilities are:
Wire EDM is best suited for electrically conductive materials. Material selection and cutting strategy are carefully managed to ensure optimal performance and finish. We commonly work with:
We offer specialized carbide cutting services using wire EDM, allowing for precise shaping of extremely hard materials used in tooling and wear-resistant components. Wire EDM is especially effective for carbide because it maintains dimensional accuracy by preventing cracking or chipping and producing clean, precise edges. We utilize this material to build stronger and longer-lasting die components for our toolroom. Learn more about carbide cutting here.
Quality is embedded in every stage of our wire EDM process. As an ISO 9001:2015 certified and ITAR registered manufacturer, we maintain strict standards while ensuring secure handling of sensitive data in compliance with NIST SP800-171.
Partnering with Wisconsin Metal Parts ensures precision, reliability, and efficiency in every wire EDM project.
What sets us apart:
We are here to serve you and help solve your manufacturing challenges.
WMP is an experienced supplier of custom metal parts for a variety of industries including aerospace, agriculture, medical and food and beverage.
Wire Electrical Discharge Machining is a manufacturing process where a very thin wire (.003-.012”) uses an electrical charge to cut through materials that conduct electricity. In Wire EDM, the wire does not actually touch the material, instead it has an electrical charge that does the cutting by causing erosion of the material through heat and flushing. This allows for an efficient method of creating very detailed and complex parts.
Aluminum, steel, copper, bronze, tool steel (hardened or soft), carbide, or any material that can conduct electricity.
Lead times in our Wire EDM department can be as quick as a few days, depending on the project and material needed.
We can run 1 piece to 1000’s of pieces. Let’s talk about your project and see if it is a good fit.
Yes, we often make prototype parts prior to production being finalized. We also make a lot of tooling components through our toolroom using Wire EDM.
DXF, DWG, STEP, Solidworks
We regularly work to +/-.0001” (0.0025mm) and are capable of holding tolerances as tight as +/-.00005” (0.0013mm).
We have cut features into material as thin as foil and as thick as 16”
Our AGIE machines can handle .003-.012” wire
We can hold finishes as fine as 4 Ra” in carbide and 8 Ra” in tool steel.
Our small hole drilling machine can handle a .010” electrode that normally produces a .013” hole. If we need to do a precision finish on a hole, we would probably be in the .015-.017” range after Wire EDM.
Using .004” diameter wire we can cut a .0025” internal radius.
