Aunov Tech supplies the NTC sensor housing (16) as a stainless steel component manufactured entirely in house. Once installed, the sensor housing protects the electronics from vibration, fluid and electromagnetic noise. One production floor covers forming, finishing and inspection, and a design change is re-sampled in one place under one roof.
Product overview
What defines this metal sensor is, the forming route, the tolerance band and the sealing faces, audited against the approved sample at each production release.
Die building, pressing and machining for this metal sensor are all in house, so the route from print to sample stays short, and every step is logged against the part number.
How it is manufactured
Every metal sensor follows the same routed path: The shell starts as coil or blank and is drawn through single and progressive dies; wall thickness is checked at the thinnest section after forming.
Each run is logged against the drawing revision, so reorders match the samples you already approved.
Materials and finishing
Everything is drawn from a fixed stock list: cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and this metal sensor is costed in carbon steel or stainless.
Cleanliness drives the finish here: polishing, zinc / nickel / chrome plating, anodising or powder coating. It is fixed on the drawing for this metal sensor, so repeat orders never reopen the question.
Later runs are measured back to the first article, and material certificates are kept per batch.
Quality control
An ISO 9001 certified system governs production: incoming material is verified against mill certificates, the CMM measures the first article dimension by dimension, and routine sampling keeps batches aligned with the first article. Thread class and sealing faces of the closed-end tube caps, are verified on every run. Where the application asks for it, torque, leak or pressure testing is added to the plan, and the report is packed with the shipment.
Where the part is used
This metal sensor normally works inside thermal sensing and appliance control assemblies for customers who buy to drawing.
The same metal sensor is used across several platforms, so one tooling set serves every position, and the drawing stays common.
Customization and options
The options customers tune most
Typical decisions customers make on this metal sensor: material grade, wall band, flange shape, thread size and finish for the working environment, and whether orders run as prototypes, pilot lots or scheduled batches.
Tooled and untooled options for this metal sensor are listed separately, so new tooling is only quoted where it is genuinely required. Nothing is implied – on tooling, the quotation is the contract for the closed-end tube caps,.
Specifications
| Item | NTC sensor housing (16) |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – samples are reverse-measured into a controlled drawing; changes are priced before they are made. |
| Tooling | Die design and toolmaking stay in house, so a die can be re-cut against the approved drawing, and the charge is refundable against agreed volumes. |
| Samples | Approval is in writing, and the signed sample is kept as the reference for repeats. |
| Materials | Stock covers carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass; special grades are sourced to the drawing when volumes justify. |
| Surface finish | Surface treatment matched to the duty: plating, coating or polishing; alternatives quoted with the quotation, samples approved in writing. |
| Processing | Deep drawing followed by CNC finishing on critical faces; first articles verify the whole flow before the run is released. |
| Equipment | Hydraulic presses for drawing, with CNC turning for finishing, with in-house toolmaking to keep dies and fixtures maintained. |
| Tolerance | +/-0.02 mm on machined seats, sealing faces flat to drawing; capability is checked on the first article before the run continues. |
| Delivery terms | FOB, with DDP offered for EU and US addresses, payment by T/T or L/C, quoted in USD or EUR; price breaks tie to annual volume. |
Packaging and delivery
The packing method protects the surfaces of this metal sensor: interleaves, bags or trays are matched to the surface treatment, in sealed export cartons, palletised and marked as you direct.
