When Wire EDM Is the Right Process
Wire EDM is most useful when conventional cutting tools are limited by material hardness, cutting force, tool access or internal geometry.
- 01
Hardened Materials
Cut heat-treated steels and other conductive hard metals without conventional tool pressure.
- 02
Narrow Slots & Internal Features
Produce narrow slots, detailed profiles and small internal features that are difficult to mill.
- 03
Thin or Delicate Parts
No direct cutting force helps reduce deformation in fragile or thin-wall components.
- 04
Complex Precision Profiles
Suitable for accurate 2D contours, inserts, dies, gauges and precision production parts.
What We Review Before Cutting
Wire EDM results depend on more than a tolerance value. Our engineers review the complete cutting condition before confirming the process.
- Material and heat-treatment condition
- Part thickness and overall dimensions
- Critical tolerances and datum relationships
- Required surface finish and skim passes
- Start-hole and wire-threading access
- Quantity and inspection requirements
- Material
- Electrically conductive metals
- Tolerance
- Reviewed by geometry and thickness
- Surface finish
- Controlled through rough and skim cuts
- Part size
- Confirmed from drawing
- Inspection
- Dimensional reports available on request
How We Manage Your Wire EDM Parts
- 01
Drawing Review
We review the geometry, material condition, tolerances, datums and inspection requirements.
- 02
Workpiece Preparation
The workpiece, start holes and clamping method are prepared according to the cutting plan.
- 03
Rough & Skim Cutting
Rough cutting removes material, followed by controlled skim passes where tighter accuracy or improved finish is required.
- 04
Inspection & Delivery
Critical dimensions are inspected against the drawing before parts move to finishing, assembly or delivery.
Conductive Materials We Work With
Wire EDM can only process electrically conductive materials. Final feasibility depends on the material grade, heat-treatment condition, thickness and drawing requirements.

- Titanium Alloys
- Nickel-Based Alloys
- Tungsten Carbide
Typical Parts
- Mold inserts and precision dies
- Gauges and inspection fixtures
- Thin precision plates
- Machine components

Wire EDM as Part of a Complete Manufacturing Plan
Wire EDM is often only one step in a multi-process part. OUJI coordinates machining, heat treatment, wire cutting, surface finishing and inspection around the same drawing and datum strategy.
Datum Control
Review how critical features relate across different manufacturing operations.
Final Verification
Inspect drawing-critical dimensions after all relevant processes are completed.
Wire EDM FAQs
Direct answers about materials, geometry, cost and quotation files.
Can Wire EDM cut non-conductive materials?
No. Wire EDM requires an electrically conductive workpiece. Plastics and most non-conductive ceramics cannot be cut using this process.
Can hardened steel be cut after heat treatment?
Yes. Wire EDM is commonly used for hardened conductive materials. The final process sequence should be reviewed according to distortion risk and dimensional requirements.
Can Wire EDM produce perfectly sharp internal corners?
Wire EDM can produce very small internal corner radii, but the final radius is limited by the wire diameter and discharge gap. Mark critical corner requirements clearly on the drawing.
What affects Wire EDM cost?
The main factors include material thickness, total cutting length, tolerance, surface-finish requirements, number of skim passes, start holes, setup complexity and quantity.
What files should I send?
STEP, STP, IGES, X_T, DWG, DXF and PDF files are accepted. Include the material grade, quantity, tolerances, heat-treatment condition and inspection requirements.
Do you accept prototype and repeat orders?
Yes. OUJI supports projects from one piece through repeat production, subject to drawing and process review.
