This Oxygen sensor case is an Aunov Tech production part in stainless steel, quoted and built to customer print. On the product, the sensor housing protects the electronics from vibration, fluid and electromagnetic noise. Forming and machining share equipment, staff and batch records, so repeat orders stay aligned with the approved sample on one production route.
Product overview
The specification of this metal sensor turns on, draw depth, wall band and the surfaces that forming cannot hold, all held to the drawing and verified at first article.
Tooling and finishing for this metal sensor run under one roof, so revisions do not wait on outside suppliers, with process data archived for repeat orders.
How the part is produced
The process for this metal sensor runs in a fixed sequence: Blanks are drawn in stages, with interstage annealing where the wall thins; the finishing operations hold the concentricity the drawing calls for.
Each run is logged against the drawing revision, so reorders match the samples you already approved.
Materials and finishing
Our stock list runs to SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this metal sensor is costed in carbon steel or stainless.
The finish is chosen for a clean working surface: polishing, zinc / nickel / chrome plating, anodising or powder coating. Once approved, the finish for this metal sensor is fixed and does not get re-decided.
Production batches of the oxygen sensor case are gauged back to the signed first article, not to a memory of it. First article, drawing revision and material cert travel with each oxygen sensor case batch.
Quality control and inspection
The plant is ISO 9001 certified: stock arrivals are checked against mill certificates, first articles are measured on a CMM, and routine sampling keeps batches aligned with the first article. Thread gauging and seal-face checks are part of every oxygen sensor case batch. Where the application asks for it, torque, leak or pressure testing is added to the plan, with certificates included in the shipment file.
Applications
This metal sensor is used in sensor and thermostat assemblies under schedules that run for years at a time.
One part number for this metal sensor frequently serves several assemblies, so one approved version covers the whole range, and no re-tooling is needed.
Specifications
| Item | Oxygen sensor case |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – DFM notes are returned before any tooling is cut; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so no tooling step is outsourced, and maintenance is tracked against the part number. |
| Samples | Prototype and pre-production samples are provided against the drawing, so the sample is retained as the master, and mass production is gated on that approval. |
| Materials | Standard stock: carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass; special grades are sourced to the drawing when volumes justify. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; masking and laser marking available where needed. |
| Processing | Deep drawing on hydraulic presses, CNC-finished where tolerances tighten; in-process checks sit between stages, not only at the end. |
| Equipment | Press line for drawing, CNC cells for finishing; first articles and batch samples are checked on the CMM. |
| Tolerance | +/-0.01 mm on turned or milled features, +/-0.03 mm on formed details; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | FOB Ningbo or Shanghai, T/T or L/C, with D/P accepted on repeat business; each volume tier carries its own quoted price. |
Also known as: oxygen sensor boxes — same part, same tooling, only the drawing reference differs.
