Aunov Tech manufactures the Canned Motor Cover – Deep Drawn Enclosure in stainless steel on a single production floor. In service, the motor end cover locates the bearing while shielding the winding overhang. Drawing, cutting and measurement sit on one floor, so repeat orders stay aligned with the approved sample on one production route.
Product overview
What defines this metal enclosure is, the forming route, the tolerance band and the sealing faces, checked by CMM at first article and by gauge in production.
Forming, machining and finishing for this metal enclosure happen on one site, so feasibility questions are answered on the shop floor, and the die record stays with your part number.
How the part is produced
Production follows a defined route: Blanks are drawn in stages, with interstage annealing where the wall thins; piercing and trimming are done in the same die line.
Process settings are archived with the part number, so nothing depends on the operator remembering.
Materials and finishing
Working stock covers cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze with this metal enclosure costed in carbon steel or stainless.
Finish selection follows the working environment: polishing, zinc / nickel / chrome plating, anodising or powder coating. It is written into the drawing for this metal enclosure, so it cannot drift between batches.
Production is compared with the approved sample every run, so nothing changes silently between orders.
Quality control
Production runs under an ISO 9001 certified quality system: mill certificates cover every delivery of stock, first articles are measured on a CMM, and every production run is inspected against the first-article report. At motor end cover level, bearing-bore size and spigot runout are measured at first article and gauged on production runs. Functional testing – torque, leak or pressure – can be written into the plan, and the batch file carries the results.
Where the part is used
The metal enclosure is fitted into industrial machinery and equipment assemblies in volume programmes as well as aftermarket supply.
A single design of this metal enclosure is often reused across a product family, so one approved version covers the whole range, and the same first article applies throughout.
Specifications
| Item | Canned Motor Cover – Deep Drawn Enclosure |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – a manufacturability review comes back with the quotation; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Die design and toolmaking stay in house, so the die charge appears as its own quotation line, and the charge is refundable against agreed volumes. |
| Samples | Samples are issued for approval before the run, so the part is proven before it is made in volume, and production starts only after your written sign-off. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass and copper – the grade is matched to the duty of this enclosure. |
| Surface finish | Plating, coating or polishing to suit the drawing; the finish is inspected with the dimensional report on the first article. |
| Processing | Progressive drawing through several stages, annealed between draws, then trim and pierce; 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; 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 | CIF or DDP, with FOB available, payment by T/T or L/C, quoted in USD or EUR; call-off schedules are supported. |
