Aunov Tech manufactures the Deep Drawn Cylinder Can in stainless steel on a single production floor. In the assembly, the deep drawn tube provides a sealed cylindrical body the assembly builds into. One production floor covers forming, finishing and inspection, and a design change is re-sampled in one place without re-quoting the job elsewhere.
Product overview
The critical features of this metal can are, material grade, wall uniformity and thread position, audited against the approved sample at each production release.
Toolroom, presses and machining centres used on this metal can operate on the same site, so feasibility questions are answered on the shop floor, and every step is logged against the part number.
Production route
This is how the metal can is built: Drawing runs from flat blank to finished envelope in one controlled sequence; the part is annealed between stages so the wall thins evenly.
Production batches of the cylinder can are gauged back to the signed first article, not to a memory of it. Process settings for the cylinder can are archived, so later runs can be compared with the one you approved.
Materials and finishing
Everything is drawn from a fixed stock list: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this metal can is costed in carbon steel or stainless.
Finish selection follows the working environment: polishing, zinc / nickel / chrome plating, anodising or powder coating. It is fixed on the drawing for this metal can, so repeat orders never reopen the question.
The cylinder can manufacturing record is archived together with the drawing revision that produced it. Deviations on the cylinder can are reported before shipment rather than found on your assembly line.
Quality control
The plant is ISO 9001 certified: stock arrivals are checked against mill certificates, the first article is CMM-measured against the print, and routine sampling keeps batches aligned with the first article. First article of the cylinder can carries wall thickness data. Functional testing – torque, leak or pressure – can be written into the plan, and results travel with the batch paperwork.
Applications
The metal can sits in industrial machinery and equipment assemblies for OEM and Tier-1 customers.
The same metal can is often run in more than one assembly, so the tightest tolerance in the family sets the spec, and the drawing stays common.
Specifications
| Item | Deep Drawn Cylinder Can |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – unusual walls, threads or tolerances are feasibility-checked first; the same drawing is used for every repeat order. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so a die can be re-cut against the approved drawing, and the die remains dedicated to your part. |
| Samples | Production does not start until the sample report has been signed off. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass and copper – the grade is matched to the duty of this can. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; masking and laser marking available where needed. |
| Processing | Coil blanking and progressive drawing, coining on the final station where the print calls for it; first articles verify the whole flow before the run is released. |
| Equipment | Press shop running 5-250 T mechanical and 250-500 T hydraulic presses, annealing ovens on site, with CNC turning centres for secondary operations and CMM inspection. |
| Tolerance | +/-0.05 mm on drawn diameters, tighter bands confirmed against the drawing; capability is checked on the first article before the run continues. |
| Delivery terms | CIF or DDP, with FOB available, payment by T/T, L/C at sight or D/P; repeat orders reuse the approved first article. |
