Aunov Tech builds this NTC thermistor temperature sensor housing in stainless steel, from coil or bar through to the finished surfaces. In duty, the sensor housing shields the sensing element and positions it in the measured medium. Forming and machining share equipment, staff and batch records, keeping first-article quality through scheduled runs without handing the part to another vendor.
Product overview
The critical features of this metal sensor are, the formed envelope, flatness and hole location, controlled from the approved first article onward.
Toolroom, presses and machining centres used on this metal sensor operate on the same site, so revisions do not wait on outside suppliers, and every step is logged against the part number.
How the part is produced
Production of this metal sensor is locked to one route: The drawn envelope is produced in stages with anneals between them; secondary machining holds the seats, threads and faces that forming cannot produce.
A bullet probe tips, looks like the simplest item in a catalogue and is often the most demanding to make consistently. The bullet probe tips, tolerances that matter are confirmed with capability data before pricing is agreed.
Materials and finishing
Working stock covers carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this metal sensor is costed in carbon steel or stainless.
Cleanliness drives the finish here: polishing, plating in zinc, nickel or chrome, anodising, powder coating, electrophoresis and passivation. The finish on this metal sensor is locked to the drawing revision, so later orders match.
The approved sample governs later runs, so the colour and grain of the finish stay stable.
Quality control and inspection
Quality management is certified to ISO 9001: stock arrivals are checked against mill certificates, a full CMM report approves the first article, and run inspections follow an agreed sampling plan. Threads are gauged and seal faces inspected on each bullet probe tips, batch. Tests for torque, leakage or pressure can be arranged when the service demands them, and the batch file carries the results.
Typical applications
The metal sensor sits in sensor and thermostat assemblies in volume programmes as well as aftermarket supply.
One drawing for this metal sensor is commonly applied to several programmes, so wall bands and finishes are selected to cover the widest duty, and the same first article applies throughout.
Customization and options
Where designs usually differ
The options most often changed on this metal sensor: material grade, coating, wall bands, flange form and end closure, and how the order is released – sample, pilot run or scheduled call-off.
The quote for this metal sensor separates tooled options from new work, so you can see which options are free and which need new tooling. Each bullet probe tips, reorder is priced with the original split.
Specifications
| Item | NTC thermistor temperature sensor housing |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – unusual walls, threads or tolerances are feasibility-checked first; the approved drawing is kept as the controlled master. |
| Tooling | Progressive and drawing dies are designed and built in house, so die cost stays transparent, and maintenance is tracked against the part number. |
| Samples | Sample parts are measured and reported before submission, so the part is proven before it is made in volume, and the signed sample is kept for future reorders. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass are held on site; the final grade is fixed with the drawing review. |
| Surface finish | Plating, coating or polishing to suit the drawing; the finish is inspected with the dimensional report on the first article. |
| 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, with CNC turning centres for secondary operations and CMM inspection. |
| Tolerance | +/-0.01 mm on sealing faces, +/-0.05 mm on drawn profiles; capability is checked on the first article before the run continues. |
| Delivery terms | CIF or DDP, with FOB available, T/T or L/C, with D/P accepted on repeat business; call-off schedules are supported. |
Packaging and delivery
Packaging protects the finished surfaces of this metal sensor: each coating gets its own packing – interleaves, bags or trays, in sealed export cartons, palletised and marked as you direct.
