The Deep Drawn Aluminum Cap – Custom Sizes is produced by Aunov Tech from stainless steel, formed and finished under one roof. Once installed, the drawn housing encloses the sensitive internals and carries the mounting interface. 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 aluminium cap is, the forming route, the tolerance band and the sealing faces, each measured at first article and gauged on production batches.
Toolroom, presses and machining centres used on this aluminium cap operate on the same site, so the route from print to sample stays short, and nothing about the route depends on a third party.
How the part is produced
Production of this aluminium cap is locked to one route: Drawing runs from flat blank to finished envelope in one controlled sequence; the finishing operations hold the concentricity the drawing calls for.
Each shipment is traceable to the signed first article, and that record is what every reorder is built from.
Materials and finishing
Standard stock includes carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and the grade agreed for this aluminium cap is aluminium.
The surface treatment is picked to match the service conditions: zinc and nickel plating, chrome, anodising, powder coating and passivation. The choice is recorded on the drawing for this aluminium cap, so the decision never has to be made twice.
Production batches of the cap – size are gauged back to the signed first article, not to a memory of it. Any change to the cap – size drawing is re-approved and re-verified before production continues.
Quality control
The factory operates with ISO 9001 certification: stock arrivals are checked against mill certificates, first-article geometry is confirmed on the CMM, and run inspections follow an agreed sampling plan. First article of the cap – size includes cavity depth and seal face finish data. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, and the inspection report ships with each batch.
Typical applications
The aluminium cap is fitted into industrial machinery and equipment assemblies in volume programmes as well as aftermarket supply.
Drawings for this aluminium cap are adapted across programmes, so the finish is chosen to cover the harshest of them, and the die does not have to change.
Specifications
| Item | Deep Drawn Aluminum Cap – Custom Sizes |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – unusual walls, threads or tolerances are feasibility-checked first; the approved drawing is kept as the controlled master. |
| Tooling | Tooling is built and held under your part number, so the die charge appears as its own quotation line, and maintenance is tracked against the part number. |
| Samples | Samples are issued for approval before the run, and production starts only after written sign-off. |
| Materials | Stock runs to carbon steel, 304 / 316 stainless, aluminium and brass; grade and temper are confirmed in writing before tooling. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; finish thickness and adhesion checked on the first article. |
| 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 | Mechanical presses 5-250 T plus 250-500 T hydraulics, with in-line annealing, backed by CNC turning centres and a climate-controlled inspection room. |
| Tolerance | +/-0.05 mm on flange and rim dimensions, wall controlled by the draw; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | FOB, with DDP offered for EU and US addresses, T/T with deposit and L/C for larger runs; call-off schedules are supported. |
