Aunov Tech builds this Stamped End Cap with Side Hole in stainless steel, from coil or bar through to the finished surfaces. On the product, the motor end cover aligns the rotor through the machined bearing bore. Forming, machining and inspection share one floor, which keeps tolerances consistent from sample to volume without re-quoting the job elsewhere.
Product overview
The drawing for this metal cap fixes, the draw ratio, corner radii and the faces that must stay flat, each measured at first article and gauged on production batches.
Die work and machining for this metal cap sit on the same floor, so feasibility questions are answered on the shop floor, and the same die can be re-cut from the original data.
Production route
The route for this metal cap is fixed and repeatable: The strip is blanked, formed and pierced in a progressive die; pierced features are checked against the die before the run is released.
The tooling record is stored against the part number, so a repeat order starts from the same approved data.
Materials and finishing
Our stock list runs to cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze with this metal cap costed in carbon steel or stainless.
The finish is chosen for the duty it will see: polishing, zinc / nickel / chrome plating, anodising or powder coating. It is written into the drawing for this metal cap, so it cannot drift between batches.
The end cap manufacturing record is archived together with the drawing revision that produced it. Deviations on the end cap are reported before shipment rather than found on your assembly line.
Quality control and inspection
The factory operates with ISO 9001 certification: certificates verify each incoming batch of material, a full CMM report approves the first article, and routine sampling keeps batches aligned with the first article. 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. Where the application asks for it, torque, leak or pressure testing is added to the plan, and the report is packed with the shipment.
Applications
The metal cap is specified into industrial and appliance assemblies in volume programmes as well as aftermarket supply.
Drawings for this metal cap are adapted across programmes, so the specification is set by the toughest of them, and the same first article applies throughout.
Specifications
| Item | Stamped End Cap with Side Hole |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – DFM notes are returned before any tooling is cut; changes are priced before they are made. |
| Tooling | The tooling record travels with the part number, so maintenance history is never lost. |
| Samples | Sample parts are measured and reported before submission, so the sample is retained as the master, and production starts only after your written sign-off. |
| Materials | Standard stock: carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass; mill certificates and heat numbers accompany the first article. |
| Surface finish | Plating, powder coating, anodising or polishing, per the print; the finish is inspected with the dimensional report on the first article. |
| Processing | Blanking and progressive forming on automated lines, then secondary tapping, bending and finishing. |
| Equipment | Mechanical presses from 5 to 250 T and hydraulic presses 250-500 T, with in-line annealing furnaces; secondary ops run on CNC turning centres, inspection on the CMM. |
| Tolerance | +/-0.1 mm general on drawn sections, +/-0.03 mm on machined seats; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | FOB Ningbo or Shanghai, payment by T/T, L/C at sight or D/P; each volume tier carries its own quoted price. |
