RFQ Checklist
- Electrode drawing, STEP file, or mold cavity reference
- Graphite grade preference or detail size requirement
- Holder interface, datum strategy, and inspection needs
- Electrode quantity per cavity and delivery schedule
Machined graphite EDM electrodes for mold shops that need fast burn performance, stable detail retention, and repeat replacement sourcing.
Complete RFQs are easier to review within 1-2 business days when drawings, graphite grade, quantity, and destination are included.
| Option | Best Fit | Watchouts |
|---|---|---|
| Roughing graphite electrodes | Bulk material removal, larger cavities, and programs where burn speed matters more than fine corner retention. | Confirm burn allowance, holder datum, and whether finishing electrodes will follow. |
| Finishing or rib electrodes | Fine cavity details, thin ribs, texture preparation, and mold areas where wear and detail retention drive acceptance. | Use a fine-grain grade and confirm minimum rib width, sharp corners, mirror direction, and inspection datum. |
| Electrode blanks | Toolrooms that want controlled graphite stock sizes but machine final details internally. | Specify blank size, squareness, surface condition, packing, and material identification requirements. |
Confirm STEP file, holder interface, datum, mirror direction, burn allowance, rough or finish role, and electrode sequence.
Select grade by detail class and surface target, then plan cutter access for ribs, cavities, and small features.
Machine under graphite dust control and label each electrode by cavity, operation, holder, revision, or buyer ID.
Check datum-critical faces and details, then pack thin ribs and sharp electrode features against handling damage.
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Detail retention | Grade and geometry dependent | Thin ribs and fine EDM details require graphite grade and machining strategy alignment. |
| Replacement repeatability | Batch-controlled drawings | Mold shops often need the same electrode geometry multiple times during tool maintenance. |
| EDM role and datum control | Roughing, finishing, rib, cavity, blank, or replacement | The electrode role controls graphite grade, allowance, labeling, inspection, and burn-plan repeatability. |
Yes. STEP files are preferred. Include holder details, datum references, electrode quantity, and whether each electrode is for roughing or finishing.
Both are possible. Finished electrodes need clearer datum and inspection requirements, while blanks can be supplied to your toolroom standard sizes.
Useful labels include cavity number, roughing or finishing role, holder reference, burn sequence, drawing revision, and buyer part ID.
