- Guidewires
- Endoscope components
Engineering Focus
- Dimensional tolerance
- Surface finish
- Material certification
Key Evaluation Matrix
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Dimensional tolerance | +/- 0.01 mm drawing-driven review | Ensures nested assembly fit. |
| Material grades | 304 / 304L / 316 / 316L stainless steel | Locks corrosion, strength, and documentation assumptions early. |
| Surface options | Cut-to-length, deburr, electropolish, passivate | Prevents friction and corrosion issues during catheter assembly. |
Buyer Decision Points Before RFQ
| Decision Factor | Confirm Before Quote | Buyer Impact |
|---|---|---|
| Material and corrosion route | 304, 304L, 316, or 316L stainless steel with passivation and certificate scope. | Prevents late material substitutions and corrosion-risk surprises during supplier qualification. |
| Drawing tolerance stack | OD, ID, wall, length, straightness, ovality, and CTQ dimensions by revision. | Keeps catheter shaft fit, guidewire passage, and bonded assembly clearance under control. |
| Prototype-to-pilot quantity plan | Sample quantity, pilot lot size, annual forecast, destination, and target ship date. | Lets engineering quote the right process lane instead of pricing a prototype like production. |
Risk Controls
- Friction in assembly: Electropolishing and passivation.
- Gauge or wall-callout ambiguity: Quote by explicit OD, ID, wall, tolerance, and drawing revision instead of relying only on gauge labels.
Manufacturing and Release Flow
- Drawing intake: Review end-use application, drawing revision, CTQ dimensions, material grade, and required documents.
- Tube preparation: Cut, grind, skive, or form tube features according to tolerance and assembly requirements.
- Surface finishing: Apply deburring, electropolishing, passivation, ultrasonic cleaning, or packaging controls as specified.
- Inspection release: Provide dimensional report, material certificate, surface notes, and lot traceability records.
Quality Evidence Buyers Can Request
- Material certificate and heat/lot traceability
- Dimensional inspection report for drawing-critical OD/ID/wall features
- Microscopic visual check for cut edge and burr condition
- Passivation or electropolishing confirmation when specified

Buyer FAQ
What grades are available?
304, 304L, 316, 316L.
Can you quote from a gauge size only?
A preliminary review is possible, but production quotes should include OD, ID, wall thickness, length, tolerance, finish, and material certificate needs.
