Support Across the Die Lifecycle
From made-to-drawing tooling to inspection, repolishing, recutting and repair, support is organized around wire material, size, surface and die-wear issues.
01Recutting, Repolishing and Repair
Used dies are inspected so repolishing, recutting or profile correction can be evaluated against wear and the next target size.
02Made-to-Drawing Tooling
Tooling is manufactured to the drawing, target hole size, casing dimensions, wire material and line conditions.
03Application and Die Selection Review
Before production, Yongyi can review the application to confirm suitable die material, geometry, surface finish and inspection requirements.
Quality Control
Inspection Built into Production
Yongyi combines die manufacturing, polishing and repair experience with inspection equipment to support stable geometry, dimensions and wire surfaces.
- Die material and geometry are reviewed against the wire material, drawing process and target size.
- Critical bore geometry and working surfaces are checked at multiple production stages.
- Inspection reports are available on request.
