This Deep drawn can is an Aunov Tech production part in stainless steel, quoted and built to customer print. Once installed, the deep drawn part replaces a machined-from-solid body with a lighter, faster drawn shell. Drawing, cutting and measurement sit on one floor, keeping first-article quality through scheduled runs without handing the part to another vendor.
Product overview
What defines this metal can is, the draw ratio, corner radii and the faces that must stay flat, re-checked whenever the drawing is revised.
The press shop and machine shop that make this metal can share one floor, so feasibility questions are answered on the shop floor, and the same die can be re-cut from the original data.
How it is manufactured
Production follows a defined route: Blanks are drawn in stages, with interstage annealing where the wall thins; the finishing operations hold the concentricity the drawing calls for.
Each can shipment is verified against the master sample before it leaves the shop. The signed can sample remains the reference and is kept with the job file.
Materials and finishing
Materials kept on the floor cover cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and the grade agreed for this metal can is 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.
Repeat can orders are measured against the approved sample, so neither material nor finish drifts between lots. Mill certificates are filed per heat, so can traceability survives a change of material batch.
Quality control
An ISO 9001 certified system governs production: incoming material is verified against mill certificates, first-article geometry is confirmed on the CMM, and production batches are inspected on a sampling plan. First-article inspection of the can runs on the CMM: thread classes gauged, diameters logged. Where the application asks for it, torque, leak or pressure testing is added to the plan, with certificates included in the shipment file.
Typical applications
You will find this metal can inside industrial equipment and general assembly work under schedules that run for years at a time.
The same metal can is used across several platforms, so wall bands and finishes are selected to cover the widest duty, and the die does not have to change.
Specifications
| Item | Deep drawn can |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – unusual walls, threads or tolerances are feasibility-checked first; changes are priced before they are made. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so die cost stays transparent, and the charge is refundable against agreed volumes. |
| Samples | Samples are produced on the production tooling, so what you approve is what you get. |
| Materials | Stock covers carbon steel (SPCC / DC01), 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 agreed finish travels with the part number. |
| Processing | Deep drawing on maintained presses, blank size and lubrication logged per run; batch records are filed so a repeat order starts from approved data. |
| Equipment | Mechanical presses from 5 to 250 T and hydraulic presses 250-500 T, with in-line annealing furnaces; secondary ops run on CNC turning centres, inspection on the CMM. |
| Tolerance | +/-0.05 mm on formed features, with capability data on critical dimensions; dimensional reports accompany the first article. |
| Delivery terms | Standard terms FOB; DDP available for EU and US, with T/T and L/C accepted. |
