The NTC thermistor temperature sensor surface mounting controller probe is produced by Aunov Tech from stainless steel, formed and finished under one roof. In operation, the sensor housing shields the sensing element and positions it in the measured medium. Drawing, cutting and measurement sit on one floor, which keeps tolerances consistent from sample to volume with no third party in the loop.
Product overview
For this metal sensor, the drawing centres on, wall thickness control, flange geometry and the sealing surface, all held to the drawing and verified at first article.
Tooling and finishing for this metal sensor run under one roof, which keeps the sample loop inside our own schedule, and the approved sample is kept as the master.
How the part is produced
The process for this metal sensor runs in a fixed sequence: Coil is blanked and drawn through progressive and single-stage dies; piercing and trimming are done in the same die line.
Production batches of the tall stepped sleeve are gauged back to the signed first article, not to a memory of it. Deviations on the tall stepped sleeve are reported before shipment rather than found on your assembly line.
Materials and finishing
Base materials in stock: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this metal sensor is costed in carbon steel or stainless.
With the working face exposed, the finish is selected for cleanliness: zinc and nickel plating, chrome, anodising, powder coating and passivation. The choice is recorded on the drawing for this metal sensor, so the decision never has to be made twice.
Paperwork matches the parts: material certs and dimensional reports on request.
Quality control
The factory operates with ISO 9001 certification: material traceability starts with mill certificates, first-article geometry is confirmed on the CMM, and production batches are inspected on a sampling plan. Every tall stepped sleeve batch carries thread gauging and seal face inspection. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, and the inspection report ships with each batch.
Typical applications
Typical installation of the metal sensor is in sensor and thermostat assemblies in both OEM and aftermarket supply.
The same metal sensor is used across several platforms, so the specification is set by the toughest of them, and approvals carry across programmes.
Customization and options
Options changed most often
Variations that come up most often on this metal sensor: grade and finish for the environment, wall thickness bands, flange and rim forms, threads, bosses and closed ends, and how the order is released – sample, pilot run or scheduled call-off.
Quotes for this metal sensor show which options the current die already supports, so you can see which options are free and which need new tooling. The tall stepped sleeve quotation carries a validity period and the price is held to it.
Specifications
| Item | NTC thermistor temperature sensor surface mounting controller probe |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – unusual walls, threads or tolerances are feasibility-checked first; the approved drawing is kept as the controlled master. |
| Tooling | Die design and toolmaking stay in house, so no tooling step is outsourced, and the charge is refundable against agreed volumes. |
| Samples | Sample approval is documented: dimensions, finish and material recorded for later comparison. |
| Materials | Stock runs to carbon steel, 304 / 316 stainless, aluminium and brass; mill certificates and heat numbers accompany the first article. |
| Surface finish | Surface treatment matched to the duty: plating, coating or polishing; masking and laser marking available where needed. |
| Processing | Drawn shell with machined seats and threads where the print calls for them; batch records are filed so a repeat order starts from approved data. |
| Equipment | Hydraulic presses for drawing, with CNC turning for finishing, backed by CNC turning centres and a climate-controlled inspection room. |
| Tolerance | +/-0.02 mm on machined seats, sealing faces flat to drawing; dimensional reports accompany the first article. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, T/T or L/C, with D/P accepted on repeat business; each volume tier carries its own quoted price. |
Packaging and delivery
Finish comes first when packing this metal sensor: interleaves, bags or trays are matched to the surface treatment, in sealed export cartons, palletised and marked as you direct.
