Aunov Tech supplies the Oxygen sensor shell as a stainless steel component manufactured entirely in house. In duty, the sensor housing protects the electronics from vibration, fluid and electromagnetic noise. Forming, machining and inspection share one floor, so first-article dimensions hold through volume batches without a second supplier involved.
Product overview
The critical features of this metal sensor are, material grade, wall uniformity and thread position, controlled from the approved first article onward.
Die building, pressing and machining for this metal sensor are all in house, so a change of wall or hole does not restart the programme, and the same die can be re-cut from the original data.
How the part is produced
The route for this metal sensor is fixed and repeatable: Coil is blanked and then drawn down in successive stages; piercing and trimming are done in the same die line.
The oxygen sensor shell tooling and setup record is stored against the part number, so nothing depends on someone remembering. The signed oxygen sensor shell sample remains the reference and is kept with the job file.
Materials and finishing
Standard stock includes carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper with this metal sensor costed in carbon steel or stainless.
With the working face exposed, the finish is selected for cleanliness: plating, anodising, powder coating, electrophoresis and passivation. The agreed finish for this metal sensor travels with the part number on every reorder.
Each oxygen sensor shell shipment is verified against the master sample before it leaves the shop. That record is what every oxygen sensor shell reorder is built on, so nothing changes silently between shipments.
Quality control
Quality management is certified to ISO 9001: material traceability starts with mill certificates, the CMM measures the first article dimension by dimension, and production batches are inspected on a sampling plan. Threads are gauged and seal faces inspected on each oxygen sensor shell batch. Functional testing – torque, leak or pressure – can be written into the plan, and the report is packed with the shipment.
Applications
This metal sensor normally works inside thermal sensing and appliance control assemblies in both OEM and aftermarket supply.
This metal sensor is supplied to several positions in the same machine, so the specification is set by the toughest of them, and no re-tooling is needed.
Specifications
| Item | Oxygen sensor shell |
|---|---|
| Brand | AUNOV |
| Designing | Quotation is built from the drawing: DFM notes come back with the price rather than after tooling. |
| Tooling | Tooling is built and held under your part number, so the die charge appears as its own quotation line, and the die remains dedicated to your part. |
| Samples | Sample parts are measured and reported before submission, so any deviation is corrected at sample stage, and the signed sample is kept for future reorders. |
| Materials | Carbon steel, 304 / 316 stainless, aluminium and brass are all held in stock; 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 | Deep drawing followed by CNC finishing on critical faces; first articles verify the whole flow before the run is released. |
| Equipment | Hydraulic drawing presses and CNC lathes for sealing faces; first articles and batch samples are checked on the CMM. |
| Tolerance | +/-0.01 mm on sealing faces, +/-0.05 mm on drawn profiles; dimensional reports accompany the first article. |
| Delivery terms | FOB, with DDP offered for EU and US addresses, T/T with deposit and L/C for larger runs; each volume tier carries its own quoted price. |
Also known as: custom sensor housings and shells — same part, same tooling, only the drawing reference differs.
