This Sheet metal stamping electric motor cover is an Aunov Tech production part in stainless steel, quoted and built to customer print. On the product, the motor end cover closes the motor stack and carries the bearing seat. One production floor covers forming, finishing and inspection, so the approved sample defines every later batch under one roof.
Product overview
The specification of this metal cover turns on, the forming route, the tolerance band and the sealing faces, checked by CMM at first article and by gauge in production.
Die building, pressing and machining for this metal cover are all in house, so feasibility questions are answered on the shop floor, and the die record stays with your part number.
How it is manufactured
Manufacturing runs on a controlled process path: Coil is fed through progressive dies that blank, form and pierce; in-die tapping keeps hole position tight, then parts are tumbled and finished.
Every sheet metal stamping order keeps its trace back to the approved first article, and a reorder is a repeat rather than a new start. First article, drawing revision and material cert travel with each sheet metal stamping batch.
Materials and finishing
Everything is drawn from a fixed stock list: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze with carbon steel or stainless specified on the drawing for this metal cover.
Finish selection follows the working environment: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. It is fixed on the drawing for this metal cover, so repeat orders never reopen the question.
The sheet metal stamping manufacturing record is archived together with the drawing revision that produced it. The approved sheet metal stamping sample governs later runs, and any grade change is agreed in writing first.
Quality control and inspection
An ISO 9001 certified system governs production: certificates verify each incoming batch of material, the first article is CMM-measured against the print, and later batches follow the sampling plan agreed at approval. At motor end cover level, bearing-bore size and spigot runout are measured at first article and gauged on production runs. Torque, leak and pressure tests are available where the assembly needs them, and the report is packed with the shipment.
Applications
Typical installation of the metal cover is in industrial machinery and equipment assemblies for OEM and Tier-1 customers.
The same metal cover is used across several platforms, so a single grade and coating can cover each application, without a second tooling round.
Specifications
| Item | Sheet metal stamping electric motor cover |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – a manufacturability review comes back with the quotation; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so a die can be re-cut against the approved drawing, and the charge is refundable against agreed volumes. |
| Samples | Sample parts are measured and reported before submission, so the approved first article becomes the gauge reference, and later batches are gauged back to the signed sample. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass and copper – the grade is matched to the duty of this cover. |
| Surface finish | Plating, coating or polishing to suit the drawing; masking and laser marking available where needed. |
| Processing | Blanking and progressive forming on automated lines, then secondary tapping, bending and finishing. |
| Equipment | 5-250 T mechanical presses, 250-500 T hydraulic presses and annealing furnaces in line, with CNC turning centres for secondary operations and CMM inspection. |
| Tolerance | +/-0.05 mm to +/-0.1 mm across the part, wall thickness held to print; capability is checked on the first article before the run continues. |
| Delivery terms | FOB Ningbo or Shanghai, T/T with deposit and L/C for larger runs; call-off schedules are supported. |
Also known as: metal fabrication electric motor end covers — same part, same tooling, only the drawing reference differs.
