Aunov Tech supplies the Electromagnetic switch housing – deep drawn as a stainless steel component manufactured entirely in house. In duty, the solenoid component carries the coil pack and guides the moving core. One production floor covers forming, finishing and inspection, so first-article dimensions hold through volume batches without re-quoting the job elsewhere.
Product overview
This metal housing is defined by, wall thickness control, flange geometry and the sealing surface, re-checked whenever the drawing is revised.
The press shop and machine shop that make this metal housing share one floor, which keeps revision loops short and samples fast, with the tooling history retained in house.
How it is manufactured
Production of this metal housing is locked to one route: Drawing runs from flat blank to finished envelope in one controlled sequence; the finishing operations hold the concentricity the drawing calls for.
Each shipment is traceable to the signed first article, and that record is what every reorder is built from.
Materials and finishing
Standard stock includes carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper with carbon steel or stainless specified on the drawing for this metal housing.
The finish is chosen for the duty it will see: zinc and nickel plating, chrome, anodising, powder coating and passivation. It is written into the drawing for this metal housing, so it cannot drift between batches.
The electromagnetic switch housing tooling and setup record is stored against the part number, so nothing depends on someone remembering. That record is what every electromagnetic switch housing reorder is built on, so nothing changes silently between shipments.
Quality control and inspection
The factory operates with ISO 9001 certification: incoming material is verified against mill certificates, first articles are measured on a CMM, and routine sampling keeps batches aligned with the first article. For the solenoid component, pole-face flatness and bore concentricity are CMM-checked at first article, with run gauging on the bore. Tests for torque, leakage or pressure can be arranged when the service demands them, and the batch file carries the results.
Where the part is used
This metal housing normally works inside industrial machinery and equipment assemblies in volume programmes as well as aftermarket supply.
The same metal housing is often run in more than one assembly, so one approved version covers the whole range, and no re-tooling is needed.
Specifications
| Item | Electromagnetic switch housing – deep drawn |
|---|---|
| Brand | AUNOV |
| Designing | Files reviewed in PDF, DWG, STEP or IGS; the signed-off revision is the reference for production. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so die cost stays transparent, and the die remains dedicated to your part. |
| Samples | Prototype and pre-production samples are provided against the drawing, so any deviation is corrected at sample stage, and mass production is gated on that approval. |
| Materials | Stock covers carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass; material substitutes are proposed only with your written approval. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; masking and laser marking available where needed. |
| 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; secondary ops run on CNC turning centres, inspection on the CMM. |
| Tolerance | +/-0.05 mm on drawn diameters, tighter bands confirmed against the drawing; finer bands confirmed from capability data before quoting. |
| Delivery terms | CIF or DDP, with FOB available, payment by T/T or L/C, quoted in USD or EUR; price breaks tie to annual volume. |
Also known as: deep drawn alloy parts — same part, same tooling, only the drawing reference differs.
