The Oxygen sensor frame is produced by Aunov Tech from stainless steel, formed and finished under one roof. Once installed, the sensor housing shields the sensing element and positions it in the measured medium. Forming, machining and inspection share one floor, keeping first-article quality through scheduled runs on one production route.
Product overview
The drawing for this metal sensor fixes, material grade, wall uniformity and thread position, each measured at first article and gauged on production batches.
Forming, machining and finishing for this metal sensor happen on one site, which keeps the sample loop inside our own schedule, and the approved sample is kept as the master.
How it is manufactured
Production follows a defined route: Coil is blanked and drawn through progressive and single-stage dies; flanges and rims are formed in the same line, then trimmed to length.
What makes a oxygen sensor frame hard is repeatability – the hundredth piece has to match the first one. Tolerances that matter are confirmed with capability data before the oxygen sensor frame is quoted.
Materials and surface finish
Everything is drawn from a fixed stock list: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and the grade agreed for this metal sensor is carbon steel or stainless.
Cleanliness drives the finish here: zinc and nickel plating, chrome, anodising, powder coating and passivation. The agreed finish for this metal sensor travels with the part number on every reorder.
Route cards follow each oxygen sensor frame batch through the shop, so the next run starts from the data that already worked. Process settings for the oxygen sensor frame are archived, so later runs can be compared with the one you approved.
Quality control
The plant is ISO 9001 certified: incoming material is verified against mill certificates, first-article geometry is confirmed on the CMM, and later batches follow the sampling plan agreed at approval. Each oxygen sensor frame batch is checked for thread class and seal face condition. Tests for torque, leakage or pressure can be arranged when the service demands them, and the inspection report ships with each batch.
Typical applications
The metal sensor is specified into thermal sensing and appliance control assemblies under schedules that run for years at a time.
Drawings for this metal sensor are adapted across programmes, so the tightest tolerance in the family sets the spec, and the drawing stays common.
Specifications
| Item | Oxygen sensor frame |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – a manufacturability review comes back with the quotation; the agreed version governs every later batch. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so the die charge appears as its own quotation line, and first-article timing is measured from the tooling start date. |
| Samples | Samples are issued for approval before the run, so the approved first article becomes the gauge reference, and mass production is gated on that approval. |
| Materials | Stock covers carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass; grade and temper are confirmed in writing before tooling. |
| Surface finish | Surface treatment matched to the duty: plating, coating or polishing; the finish is inspected with the dimensional report on the first article. |
| Processing | Blanking, drawing and piercing in sequence, then machining of sealing faces; every stage is logged against your part number. |
| Equipment | Hydraulic drawing presses and CNC lathes for sealing faces, backed by CNC turning centres and a climate-controlled inspection room. |
| Tolerance | +/-0.03 mm on stepped bores, concentricity per print; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | Freight, Incoterm and payment term are confirmed on the order: FOB, CIF or DDP, T/T or L/C. |
