Product Overview
Wire EDM, or electrical discharge machining, removes material with controlled electrical discharges between a travelling wire and the workpiece rather than with a cutting tool. Because there is no mechanical cutting force, thin walls and delicate profiles are cut without distortion, and hardened material is no harder to cut than soft material.
This makes wire EDM the right process for die and mould components, intricate profiles and features that a milling cutter cannot physically reach.
Key Benefits
No Cutting Force
Thin walled configurations and intricate shapes are cut without distortion.
Hardened Material Capability
Hardness does not limit the process, so parts can be cut after heat treatment.
Sharp Internal Corners
Internal corner radii are limited by wire diameter rather than by cutter diameter.
Excellent Repeatability
The same profile is reproduced across a batch without tool wear changing the geometry.
Application Scenarios and Who It Is For
- Die and mould components
- Punch and die inserts
- Intricate profiled components
- Thin walled precision parts
- Hardened steel components requiring accurate profiles
If your application is not listed, send the drawing anyway. Most of our work arrives as a part nobody else wanted to quote.

Manufacturing Process and Quality Control
Drawing Review
Our engineers review manufacturability, confirm tolerances and raise anything in the drawing that would cause a problem before production starts.
Sample Approval
Free samples are offered prior to mass production, with first piece inspection recorded against your drawing.
Production Control
In-process inspection at a set frequency during the run, using the coordinate measuring machine and gauges in our inspection room.
Surface Treatment
Anodizing, sand blasting, polishing, electroplating and powder coating applied in house after deburring and cleaning.
Final Inspection
The finished lot is checked against the drawing before packing, with certification issued for the stages you require.
Packing and Delivery
Protective packing appropriate to the part, dispatched within the agreed delivery date.
Customization Options
- Material — specify a grade from our catalog, or describe the function and our engineers will recommend one.
- Tolerance — standard machining tolerance is 0.005 to 0.01 mm; tighter callouts are discussed at quotation.
- Surface finish — anodized, sand blasted, polished, electroplated, powder coated or as machined.
- Marking — laser engraving and CNC engraving for part numbers and logos.
- Quantity — from a single prototype through to long production contracts.
- Certification — certification provided at each stage on request.

Product FAQ
Can wire EDM cut any material?
It cuts electrically conductive materials. Hardness is not a limitation, which is its main advantage over milling.
Why choose wire EDM over milling?
For sharp internal corners, very thin sections and hardened material, where a cutter would deflect, wear or simply not fit.
Is wire EDM slow?
It is slower per cubic millimetre than milling, so it is used where it is genuinely needed rather than as a general purpose process. We will tell you when milling would serve you better.
How do I order this part?
Do you offer free samples?
Yes, free samples are offered prior to mass production so you can confirm the part before committing to a run.
