Aunov Tech supplies the Sheet metal forming electric motor end shields as a stainless steel component manufactured entirely in house. Once installed, the drawn housing provides a closed, seam-free body the customer builds into. Forming and machining share equipment, staff and batch records, so the approved sample defines every later batch without handing the part to another vendor.
Product overview
The critical features of this metal component are, the formed envelope, flatness and hole location, checked by CMM at first article and by gauge in production.
Die building, pressing and machining for this metal component are all in house, so feasibility questions are answered on the shop floor, and nothing about the route depends on a third party.
How the part is produced
The route for this metal component is fixed and repeatable: The shell is drawn from a blank in successive stages, annealed where the wall thins; secondary machining holds the seats, threads and faces that forming cannot produce.
Batch records for the sheet metal forming are filed against the part number, so process settings are reused instead of re-invented. Deviations on the sheet metal forming are reported before shipment rather than found on your assembly line.
Materials and finishing
Materials kept on the floor cover carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper with this metal component costed in carbon steel or stainless.
The finish is chosen for the duty it will see: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. It is written into the drawing for this metal component, so it cannot drift between batches.
Batch records for the sheet metal forming are filed against the part number, so process settings are reused instead of re-invented. Process settings for the sheet metal forming are archived, so later runs can be compared with the one you approved.
Quality control
Quality management is certified to ISO 9001: stock arrivals are checked against mill certificates, the first article is CMM-measured against the print, and routine sampling keeps batches aligned with the first article. First-article measurement of the sheet metal forming covers cavity depth and seal face finish. Tests for torque, leakage or pressure can be arranged when the service demands them, and the batch file carries the results.
Typical applications
The metal component sits in industrial machinery and equipment assemblies across automotive, appliance and industrial programmes.
The same metal component is often run in more than one assembly, so a single grade and coating can cover each application, and no re-tooling is needed.
Specifications
| Item | Sheet metal forming electric motor end shields |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – DFM notes are returned before any tooling is cut; the same drawing is used for every repeat order. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so no tooling step is outsourced, and maintenance is tracked against the part number. |
| Samples | First-article samples ship with a dimensional report and material certificate, so the part is proven before it is made in volume, and production starts only after your written sign-off. |
| Materials | Carbon steel, 304 / 316 stainless, aluminium and brass are all held in stock; mill certificates and heat numbers accompany the first article. |
| Surface finish | Plating, powder coating, anodising or polishing, per the print; the agreed finish travels with the part number. |
| Processing | Progressive drawing through several stages, annealed between draws, then trim and pierce; in-process checks sit between stages, not only at the end. |
| 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; finer bands confirmed from capability data before quoting. |
| Delivery terms | FOB, CIF or DDP per Incoterms – payment by T/T or L/C, with shipping quoted door-to-door. |
