Precision drawn steel tubes with cross-drilled holes, the holes drilled after drawing through a jig that indexes off the tube OD. Cross holes pass grease, air or a locking pin; entry burrs are removed so nothing sheds downstream.
Function and Design
Most of the difficulty in a tube is invisible: wall consistency, concentricity, burr control. The tube is checked against the drawing at each stage, not only at final inspection.
Key Features
- Your print governs dimensions and features; the page shows the family.
- In-house tooling keeps volume pricing competitive on repeat orders.
- Consistent batch quality – first article verified, production sampled against the same dimensions.
- Material: The tube runs on carbon steel (SPCC / DC01 or to print) as standard; hardness or temper per print on request.
- Process: drawn-tube production for the tube with anneal windows logged per batch, burr-free piercing on the second operation.
- Finish: Natural by default on the tube; plating, powder and e-coat options priced with the quotation.
- Size: The tube is built to your drawing – the family covers the common range, your dimensions are quoted per print.
- Custom: OEM/ODM to drawing; free samples of the tube and a manufacturability review before tooling.
Where It Is Used
It earns its place in temperature probe assemblies, medical and food-grade devices, automotive sensor stems.
Why Source It From Aunov
Tube work is unforgiving: a few hundredths in the wrong place and the assembly will not go together. The tube is checked against the drawing at each stage, not only at final inspection.
