Aunov Tech builds this Metal stamping DC motor cover in stainless steel, from coil or bar through to the finished surfaces. In duty, the motor end cover aligns the rotor through the machined bearing bore. Forming, machining and inspection share one floor, and a design change is re-sampled in one place with no third party in the loop.
Product overview
What defines this metal cover is, the formed envelope, flatness and hole location, checked by CMM at first article and by gauge in production.
Forming, machining and finishing for this metal cover happen on one site, so feasibility questions are answered on the shop floor, with the tooling history retained in house.
How it is manufactured
Manufacturing runs on a controlled process path: Progressive dies blank, form and pierce from coil in one pass; in-die tapping keeps hole position tight, then parts are tumbled and finished.
Every metal stamping dc order keeps its trace back to the approved first article, and a reorder is a repeat rather than a new start. Deviations on the metal stamping dc are reported before shipment rather than found on your assembly line.
Materials and finishing
Base materials in stock: carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this metal cover is costed in carbon steel or stainless.
Coating and polishing are matched to the end use: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. The choice is recorded on the drawing for this metal cover, so the decision never has to be made twice.
Repeat metal stamping dc orders are measured against the approved sample, so neither material nor finish drifts between lots. The approved metal stamping dc sample governs later runs, and any grade change is agreed in writing first.
Quality control
The plant is ISO 9001 certified: stock arrivals are checked against mill certificates, first-article geometry is confirmed on the CMM, and production batches are inspected on a sampling plan. Part-specific checks apply as well: on the motor end cover, 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.
Typical applications
The metal cover is specified into industrial and appliance assemblies for customers who own the drawing and the tooling.
Drawings for this metal cover are adapted across programmes, so a single grade and coating can cover each application, and the drawing stays common.
Specifications
| Item | Metal stamping DC motor cover |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – samples are reverse-measured into a controlled drawing; the same drawing is used for every repeat order. |
| Tooling | Die design and toolmaking stay in house, so a die can be re-cut against the approved drawing, 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 | Materials held include carbon steel, 304 / 316 stainless, aluminium and brass; material substitutes are proposed only with your written approval. |
| Surface finish | Natural, plated or coated – the print decides, and the agreed finish is logged; the finish is inspected with the dimensional report on the first article. |
| Processing | Multi-stage deep drawing with interstage annealing, trimmed and pierced in following dies; first articles verify the whole flow before the run is released. |
| Equipment | 5-250 T mechanical presses, 250-500 T hydraulic presses and annealing furnaces in line; first articles and batch samples are checked on the CMM. |
| Tolerance | +/-0.03 mm on turned secondary features, +/-0.1 mm on as-drawn walls; dimensional reports accompany the first article. |
| Delivery terms | FOB, with DDP offered for EU and US addresses, payment by T/T or L/C, quoted in USD or EUR; repeat orders reuse the approved first article. |
