The Metal Motor Covers – Custom Stamping is produced by Aunov Tech from stainless steel, formed and finished under one roof. In the assembly, the motor end cover closes the motor stack and carries the bearing seat. Forming and machining share equipment, staff and batch records, and a design change is re-sampled in one place with no third party in the loop.
Product overview
What matters most on this metal cover is, wall thinning, concentricity and the finished mating faces, all held to the drawing and verified at first article.
Die work and machining for this metal cover sit on the same floor, which keeps revision loops short and samples fast, and nothing about the route depends on a third party.
Production route
Manufacturing runs on a controlled process path: Strip is fed through a progressive die that completes the profile; pierced features are checked against the die before the run is released.
Repeat metal motor cover orders are measured against the approved sample, so neither material nor finish drifts between lots. First article, drawing revision and material cert travel with each metal motor cover batch.
Materials and finishing
Materials kept on the floor cover carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper with carbon steel or stainless specified on the drawing for this metal cover.
Finish selection follows the working environment: zinc and nickel plating, chrome, anodising, powder coating and passivation. The finish on this metal cover is locked to the drawing revision, so later orders match.
Each metal motor cover shipment is verified against the master sample before it leaves the shop. Process settings for the metal motor cover are archived, so later runs can be compared with the one you approved.
Quality control and inspection
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. On the motor end cover itself, bearing-bore size and spigot runout are measured at first article and gauged on production runs. Tests for torque, leakage or pressure can be arranged when the service demands them, and results travel with the batch paperwork.
Applications
The metal cover is specified into industrial and appliance assemblies under schedules that run for years at a time.
One part number for this metal cover frequently serves several assemblies, so the specification is set by the toughest of them, and approvals carry across programmes.

| Samples | First-article samples ship with a dimensional report and material certificate, so any deviation is corrected at sample stage, and the signed sample is kept for future reorders. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass and copper – the grade is matched to the duty of this cover. |
| Surface finish | Surface treatment matched to the duty: plating, coating or polishing; the finish is inspected with the dimensional report on the first article. |
| Processing | Coil feeding and progressive die blanking, forming, piercing or in-die tapping, deburring, then plating. |
