Aunov Tech supplies the Cold Drawn Motor Cover – Precision Housing as a stainless steel component manufactured entirely in house. Once installed, the motor end cover closes the motor stack and carries the bearing seat. Forming, machining and inspection share one floor, keeping first-article quality through scheduled runs without handing the part to another vendor.
Product overview
For this metal housing, the drawing centres on, the forming route, the tolerance band and the sealing faces, audited against the approved sample at each production release.
Forming, machining and finishing for this metal housing happen on one site, so the route from print to sample stays short, and every step is logged against the part number.
How it is manufactured
Manufacturing runs on a controlled process path: Drawing converts a flat blank into the finished envelope in one controlled sequence; threads are single-pointed or rolled and seats bored in one setup where possible.
The cold motor cover manufacturing record is archived together with the drawing revision that produced it. That record is what every cold motor cover reorder is built on, so nothing changes silently between shipments.
Materials and finishing
Base materials in stock: carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this metal housing runs in carbon steel or stainless.
Coating and polishing are matched to the end use: electrophoresis, powder coating, anodising and zinc / nickel plating. It is written into the drawing for this metal housing, so it cannot drift between batches.
The cold motor cover tooling and setup record is stored against the part number, so nothing depends on someone remembering. That record is what every cold motor cover reorder is built on, so nothing changes silently between shipments.
Quality control
The plant is ISO 9001 certified: stock arrivals are checked against mill certificates, first-article geometry is confirmed on the CMM, and later batches follow the sampling plan agreed at approval. For the motor end cover, 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 the report is packed with the shipment.
Applications
The metal housing sits in industrial machinery and equipment assemblies for OEM and Tier-1 customers.
A single design of this metal housing is often reused across a product family, so the specification is set by the toughest of them, without a second tooling round.
Specifications
| Item | Cold Drawn Motor Cover – Precision Housing |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – a manufacturability review comes back with the quotation; the agreed version governs every later batch. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so tooling lead time stays under our control, and ownership is confirmed on the quotation. |
| Samples | First-article samples ship with a dimensional report and material certificate, so the approved first article becomes the gauge reference, and production starts only after your written sign-off. |
| Materials | Materials held include carbon steel, 304 / 316 stainless, aluminium and brass; special grades are sourced to the drawing when volumes justify. |
| Surface finish | Plating, coating or polishing to suit the drawing; the agreed finish travels with the part number. |
| Processing | Coil blanking and progressive drawing, coining on the final station where the print calls for it; every stage is logged against your part number. |
| 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; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | CIF or DDP, with FOB available, T/T or L/C, with D/P accepted on repeat business; sea or air freight is quoted to your door. |
