| Post-Process Recommendation | Polishing, lapping, chemical cleaning, passivation, stress relief or recast-layer removal for critical surfaces |
EDM Feasibility Notes
We review EDM feasibility for P20 Mold Steel using the drawing geometry, conductive material condition, tolerance, surface finish, quantity and inspection requirements.
Material Behavior in EDM
We review P20 Mold Steel according to material grade, conductivity, heat treatment condition, feature geometry, tolerance, surface finish and inspection requirements before confirming the EDM route.
Process Capability Facts
The selected EDM process suitability depends on drawing access, feature geometry, material conductivity, electrode or wire path, flushing conditions and the required inspection method.
Tolerance and Surface Finish Expectations
Typical tolerance and surface finish depend on material, thickness, feature geometry, flushing, finishing passes, machine setup and inspection method. Final values must be confirmed from the drawing.
Thickness and Geometry Review Notes
Review part thickness, feature depth, inside radii, cutting access and geometry stability before confirming the EDM route for P20 Mold Steel.
Surface Integrity and Recast Layer Review
EDM can create a recast or white layer and other thermal surface effects. Critical surfaces should identify post-processing and inspection requirements on the drawing.
Inspection and Drawing Requirements
Please include material grade, drawing revision, critical dimensions, datums, tolerance, surface finish, quantity and any inspection report requirements. We confirm the inspection method according to the drawing before quotation.
Sample Before Batch Production
Sample approval is recommended before batch production when tolerance, surface integrity, material response, geometry or documentation requirements must be confirmed. After sample approval, batch production requirements should retain the approved drawing revision and inspection plan.
Drawing Requirement Checklist
Send us the drawing and manufacturing requirements so we can review material, tolerance, inspection and batch-production feasibility.
- Please provide drawings, material grade, quantity, critical dimensions, tolerance, surface finish and inspection requirements.
- Drawing is strongly recommended for any quotation; required for tight tolerance, micro feature, cavity, export/compliance or batch production review.

Frequently Asked Questions
Can P20 Mold Steel be machined with EDM?
EDM may be reviewed when the material is electrically conductive and the drawing defines the required geometry, tolerance, finish and inspection method.
Which EDM processes are commonly reviewed for P20 Mold Steel?
We review wire EDM, sinker EDM, small hole EDM drilling or micro EDM based on feature access, thickness, cavity shape, hole size and surface requirements.
What material details should be included in the review?
Please provide material grade, heat treatment condition, stock size, required certificates if applicable and any critical surface or edge requirements.
Does heat treatment affect EDM review for P20 Mold Steel?
Yes. Heat treatment and final hardness can affect cutting strategy, distortion risk, finishing passes and inspection planning.
What inspection information should be provided?
Include critical dimensions, tolerance callouts, surface roughness targets and any report or material document requirements shown on the drawing.
