01 / Input record
Start with the forming operation, not a catalogue number.
The part print defines geometry. The operation defines why that geometry is stressed: impact, strip clearance, wall reduction, powder ejection, edge shear or an orienting magnetic field. Review both together before selecting a material or assembly direction.
Worn part or failure evidence
Send scaled overview and close-up photos, the mating assembly and the failure location. State whether the part cracked, galled, chipped, lost its edge, changed fit or caused magnetic interference.
Shape record
Finished profile, shoulder radii, lead-in, working land and controlled bore or edge.
Service record
Workpiece, reduction or stroke, lubricant, ejection condition and previous failure.
Assembly record
Stress ring, casing, retainer, spacer stack or mating punch and the intended fit.
02 / Die & mold type register
One register for the forming route and the part that carries the load.
This is a review map, not a fixed catalogue. Material direction and manufacturability are evaluated against the drawing and operating record.
| Component / route | Failure to control | What the review checks | Material direction |
|---|---|---|---|
| Cold-heading die insert / punch | Longitudinal split, impact fatigue, bore galling | Wire grade, reduction, entry lead-in, stress ring and EDM finish | Tough WC-Co direction |
| Stamping punch / die insert / bushing | Edge chipping, spalling, fatigue and strip galling | Compound, progressive or transfer architecture; clearance, support and stripping | Toughness / wear balance by station |
| Ironing or redraw die | Aluminum pickup, axial scoring, ringing wear and radial fatigue | Reduction stage, lubricant, polish direction, casing and final sizing sequence | Fine-grain WC-Co direction |
| Drawing die / mandrel | Inlet wear, bell-mouthing, galling and profile loss | Pass schedule, entry angle, bearing length, finish and support | Wear / toughness balance |
| Extrusion die / nib | Nib fracture, bearing galling and recast cracking | Deformation ratio, bearing length, support condition and corner radii | Impact-resistant WC-Co direction |
| Powder-compaction die liner / punch | Axial galling, edge chipping and radial burst | Powder, ejection force, polish orientation, pre-stress rings and EDM removal | Fine-grain WC-Co direction |
| Slitter or rotary cutting knife | Edge chipping, rounding, burr and axial wobble | Foil or sheet, clearance, edge preparation, runout and spacer stack | Micrograin WC-Co direction |
| Non-magnetic die / punch / liner | Magnetic interference, powder pickup, EDM micro-cracking and edge chipping | Target permeability and test method, orienting field, powder, impact and finishing | WC-Ni / WC-Ni-Cr direction |
Capability, tolerance and minimum quantity are assessed part by part. No universal tolerance, tool life or batch level is implied by this register.
03 / Failure & control
Choose the control after naming the failure.
Failure evidence changes the route: a tougher grade alone does not correct a bad shrink fit, an untreated EDM surface or a polish direction that traps material.
Impact chipping & fatigue
Review corner radii, punch support, strip clearance and the balance between wear resistance and toughness.
Galling & metal pickup
Review binder direction, surface finish, polishing direction, lubricant and the sliding or ejection route.
Hoop tension & burst
Review the carbide / steel assembly, stress rings, interference intent and the sequence of shrink fitting.
WEDM recast
Plan removal of the affected wire-EDM layer and finish critical working surfaces after assembly where the sequence requires it.
Abrasion & profile loss
Match grain and binder direction to the workpiece, pressure and wear path; define the working land that must remain.
Magnetic interference
Review the nickel-binder route against the stated permeability target and test method, then control powder pickup and EDM condition.
GENERIC ASSEMBLY CHECK
Carbide working member / steel support / controlled bore
Process illustration, not to scale. Final geometry and fit come from the approved drawing.04 / Non-magnetic die route
Define the magnetic requirement before choosing a grade.
Pure tungsten carbide is non-magnetic; conventional WC-Co can interfere because the cobalt binder is ferromagnetic. For magnetic-material compaction, sensor-adjacent tooling or applications where metal pickup matters, we evaluate a WC-Ni or WC-Ni-Cr direction.
“Non-magnetic” is not a complete specification. The print should state the target relative magnetic permeability and the test method. We compare that target with the proposed nickel-binder grade and the required mechanical duty.
For a non-magnetic die review, send:
- Target permeability and the customer-specified test method
- Workpiece or magnetic powder, compaction pressure and orienting field
- Impact level, edge geometry and the previous failure
- Critical fits, mating inserts, stress rings and finishing sequence
Nickel binders can change the impact and wear balance. A non-magnetic direction is therefore evaluated against the die route; it is not presented here as an automatic substitute for every WC-Co tool.
05 / From drawing to die insert
Turn the forming problem into one reviewable manufacturing route.
- 01 / RECEIVECollect the definition
Drawing or CAD, workpiece, operation, mating assembly and failure evidence arrive together.
- 02 / DIAGNOSEName the governing failure
Separate impact, galling, hoop tension, recast damage, abrasion and magnetic interference.
- 03 / SELECTSet material and assembly direction
Balance WC-Co or nickel-binder direction with the support, edge, bore and fit requirements.
- 04 / DEFINEPlan machining and finish sequence
Account for EDM removal, lapping direction, shrink assembly and final working surfaces.
- 05 / CONFIRMClose assumptions before quotation
Open geometry, capability or test-method questions are returned with the technical route.
06 / What to send
Send the strongest definition you have.
A complete package shortens technical review. If a controlled drawing is not yet available, send the worn part, scaled photos and dimensions so the missing definition can be identified.

FAQ
Questions that change the review route.
Can you quote without a finished drawing?
A drawing is the strongest input. If it is unavailable, send a worn part, scaled photos, key dimensions, the mating assembly and the failure history. The reply will identify what still needs definition before a route can be confirmed.
What must be specified for a non-magnetic die?
State the target relative magnetic permeability and the test method. Also provide the magnetic powder or workpiece, orienting field, compaction pressure, impact condition, critical fits and finishing sequence. The WC-Ni or WC-Ni-Cr direction is then evaluated against those requirements.
Can a prototype or short run be reviewed?
Prototype and short-run work are part of the custom route. Minimum quantity and total scope are confirmed per drawing and manufacturing step; this page does not publish a universal minimum.
How are EDM and shrink fitting handled in the review?
The route identifies whether the wire-EDM recast layer must be removed, when a casing or stress ring is used, and which working surface should be finished after assembly. These decisions stay tied to the approved drawing and fit intent.
