Aunov Tech supplies the Deep drawn brass tube as a stainless steel component manufactured entirely in house. In operation, the deep drawn tube guides or contains the mating part along its bore. One production floor covers forming, finishing and inspection, so repeat orders stay aligned with the approved sample without a second supplier involved.
Product overview
The specification of this brass tube turns on, material grade, wall uniformity and thread position, each measured at first article and gauged on production batches.
Die building, pressing and machining for this brass tube are all in house, so revisions do not wait on outside suppliers, and the approved sample is kept as the master.
Production route
The process for this brass tube runs in a fixed sequence: The shell is drawn from a blank in successive stages, annealed where the wall thins; piercing and trimming are done in the same die line.
Every tube order keeps its trace back to the approved first article, and a reorder is a repeat rather than a new start. Mill certificates are filed per heat, so tube traceability survives a change of material batch.
Materials and finishing
Standard stock includes SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze with H62 brass specified on the drawing for this brass tube.
Finish selection follows the working environment: plating, anodising, powder coating, electrophoresis and passivation. The agreed finish for this brass tube travels with the part number on every reorder.
Every tube order keeps its trace back to the approved first article, and a reorder is a repeat rather than a new start. Deviations on the tube are reported before shipment rather than found on your assembly line.
Quality control and inspection
Quality management is certified to ISO 9001: certificates verify each incoming batch of material, the CMM measures the first article dimension by dimension, and every production run is inspected against the first-article report. Wall section of the tube is verified at first article. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, with certificates included in the shipment file.
Applications
The brass tube is specified into industrial machinery and equipment assemblies for customers who own the drawing and the tooling.
One part number for this brass tube frequently serves several assemblies, so one tooling set serves every position, and the drawing stays common.
Specifications
| Item | Deep drawn brass tube |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – unusual walls, threads or tolerances are feasibility-checked first; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Die design and toolmaking stay in house, so no tooling step is outsourced, and the die remains dedicated to your part. |
| Samples | First-article samples ship with a dimensional report and material certificate, so the approved first article becomes the gauge reference, and later batches are gauged back to the signed sample. |
| Materials | H62 / H65 brass, 0.8-4.0 mm, selected for conductivity, fine surface detail and corrosion resistance on this tube. |
| Surface finish | Plating, powder coating, anodising or polishing, per the print; masking and laser marking available where needed. |
| Processing | Progressive drawing through several stages, annealed between draws, then trim and pierce; every stage is logged against your part number. |
| Equipment | Mechanical presses 5-250 T plus 250-500 T hydraulics, with in-line annealing; secondary ops run on CNC turning centres, inspection on the CMM. |
| Tolerance | +/-0.03 mm on turned secondary features, +/-0.1 mm on as-drawn walls; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | FOB with DDP offered for EU and US addresses; payment T/T or L/C, freight quoted to destination. |
