Produced in stainless steel by Aunov Tech, the Metal forming electric motor end shields is formed and machined on the same floor. In service, the drawn housing encloses the sensitive internals and carries the mounting interface. One production floor covers forming, finishing and inspection, which keeps tolerances consistent from sample to volume on one production route.
Product overview
For this metal component, the drawing centres on, draw depth, wall band and the surfaces that forming cannot hold, all held to the drawing and verified at first article.
Die building, pressing and machining for this metal component are all in house, so a drawing change is absorbed in one step, and the approved sample is kept as the master.
How it is manufactured
Production of this metal component is locked to one route: Coil is blanked and drawn through progressive and single-stage dies; threads are single-pointed or rolled and seats bored in one setup where possible.
The metal forming electric tooling and setup record is stored against the part number, so nothing depends on someone remembering. The approved metal forming electric sample governs later runs, and any grade change is agreed in writing first.
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 component.
The finish is chosen for the duty it will see: zinc and nickel plating, chrome, anodising, powder coating and passivation. The finish on this metal component is locked to the drawing revision, so later orders match.
Each shipment is verified against the master sample, with mill certificates filed per heat.
Quality control
The plant is ISO 9001 certified: mill certificates cover every delivery of stock, first-article geometry is confirmed on the CMM, and production batches are inspected on a sampling plan. Seal face finish and cavity depth are measured on the metal forming electric first article. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, and the report is packed with the shipment.
Applications
This metal component is used in industrial machinery and equipment assemblies in both OEM and aftermarket supply.
The same metal component is used across several platforms, so the finish is chosen to cover the harshest of them, and the drawing stays common.
Specifications
| Item | Metal forming electric motor end shields |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – a manufacturability review comes back with the quotation; the approved drawing is kept as the controlled master. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so die cost stays transparent, and ownership is confirmed on the quotation. |
| Samples | Prototype and pre-production samples are provided against the drawing, so any deviation is corrected at sample stage, and later batches are gauged back to the signed sample. |
| Materials | Materials held include carbon steel, 304 / 316 stainless, aluminium and brass; grade and temper are confirmed in writing before tooling. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; the agreed finish travels with the part number. |
| Processing | Deep drawing on maintained presses, blank size and lubrication logged per run; 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 on flange and rim dimensions, wall controlled by the draw; critical dimensions carry CMM data with the shipment. |
| Delivery terms | FOB Ningbo or Shanghai, payment by T/T, L/C at sight or D/P; sea or air freight is quoted to your door. |
