- Assembly method
Key Evaluation Matrix
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Dimensional fit | +/- 0.01 mm drawing-driven review | Prevents slippage or cracking. |
| Material choices | Pt-Ir, tantalum, gold, custom radiopaque alloy | Balances fluoroscopic visibility, wall thickness, and cost. |
| Wall thickness | Thin-wall micro ring feasibility review | Controls catheter profile while preserving marker visibility. |
Buyer Decision Points Before RFQ
| Decision Factor | Confirm Before Quote | Buyer Impact |
|---|---|---|
| Radiopacity target | Pt-Ir, tantalum, gold, or custom alloy with expected fluoroscopic visibility. | Balances imaging contrast, wall thickness, cost, and crimping behavior before ordering. |
| Fit and retention | ID/OD/wall/length tolerance, shaft OD, crimp method, and pull-off expectation. | Reduces slippage, cracking, and profile growth in balloon or stent delivery assemblies. |
| Cut edge finish | Chamfer, burr limit, edge radius, and visual inspection requirement. | Protects the catheter surface and downstream yield during marker-band assembly. |
Risk Controls
- Edge damage during assembly: Define chamfer and deburr requirements.
- Band slippage or profile growth: Match band ID, wall, length, shaft OD, crimp method, and pull-off expectation before ordering.
Manufacturing and Release Flow
- Material selection: Compare radiopacity, strength, malleability, and cost for Pt-Ir, tantalum, gold, or alternatives.
- Micro ring cutting: Cut marker bands to controlled length, wall, and diameter for catheter fit.
- Edge conditioning: Deburr, chamfer, clean, and inspect edges to protect assembly surfaces.
- Lot release: Ship with material record, dimensional report, and packaging suited for micro components.
Quality Evidence Buyers Can Request
- Material and alloy confirmation for radiopaque bands
- ID/OD/wall/length dimensional inspection
- Burr-free edge and chamfer visual check
- Packaging and lot traceability for small precision rings
