Aunov Tech manufactures the Stainless Steel 304 Precision Micro Capillary Tube End Forming Deep in stainless steel on a single production floor. In the assembly, the deep drawn tube guides or contains the mating part along its bore. The same floor forms, machines and inspects the part, so the approved sample defines every later batch under one roof.
Product overview
For this stainless steel tube, the drawing centres on, wall thickness control, flange geometry and the sealing surface, each measured at first article and gauged on production batches.
Forming, machining and finishing for this stainless steel tube happen on one site, so feasibility questions are answered on the shop floor, and nothing about the route depends on a third party.
How the part is produced
Every stainless steel tube follows the same routed path: Coil is blanked and then drawn down in successive stages; wall thickness is checked at the thinnest section after forming.
Repeat closed sensor sleeve orders are measured against the approved sample, so neither material nor finish drifts between lots. The signed closed sensor sleeve sample remains the reference and is kept with the job file.
Materials and finishing
The standard stock list carries cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and this stainless steel tube is costed in 304 / 316 stainless steel.
Finish selection follows the working environment: plating, anodising, powder coating, electrophoresis and passivation. The choice is recorded on the drawing for this stainless steel tube, so the decision never has to be made twice.
Repeat closed sensor sleeve orders are measured against the approved sample, so neither material nor finish drifts between lots. The signed closed sensor sleeve sample remains the reference and is kept with the job file.
Quality control and inspection
Quality management is certified to ISO 9001: material traceability starts with mill certificates, the CMM measures the first article dimension by dimension, and production batches are inspected on a sampling plan. Wall thickness is measured on the closed sensor sleeve first article and followed through the run. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, and the batch file carries the results.
Applications
This stainless steel tube is used in industrial equipment and general assembly work for OEM and Tier-1 customers.
The same stainless steel tube is often run in more than one assembly, so one tooling set serves every position, without a second tooling round.
Customization and options
The options customers tune most
The parts of the print for this stainless steel tube that get adjusted: material grade, wall band, flange shape, thread size and finish for the working environment, and whether the programme starts as a sample or a full release.
Tooled and untooled options for this stainless steel tube are listed separately, so the cost of a change is visible before you commit. Tooling ownership for the closed sensor sleeve is part of the written quotation.
Specifications
| Item | Stainless Steel 304 Precision Micro Capillary Tube End Forming Deep |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – DFM notes are returned before any tooling is cut; changes are priced before they are made. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so no tooling step is outsourced, and the charge is refundable against agreed volumes. |
| Samples | Sample lead time is quoted with the order, and the approved sample governs the run. |
| Materials | Stock runs to carbon steel, 304 / 316 stainless, aluminium and brass; the final grade is fixed with the drawing review. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; the finish is inspected with the dimensional report on the first article. |
| Processing | Drawn shell with machined seats and threads where the print calls for them; batch records are filed so a repeat order starts from approved data. |
| Equipment | Hydraulic presses for drawing, with CNC turning for finishing; secondary ops run on CNC turning centres, inspection on the CMM. |
| Tolerance | +/-0.01 mm on sealing faces, +/-0.05 mm on drawn profiles; finer bands confirmed from capability data before quoting. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, payment by T/T or L/C, quoted in USD or EUR; sea or air freight is quoted to your door. |
Packaging and delivery
The packing method protects the surfaces of this stainless steel tube: the coating decides whether parts are interleaved, bagged or tray-packed, in sealed export cartons, palletised and marked as you direct.
