Aunov Tech manufactures the Temperature Sensor Housing with Double-tube Welded Flange Base in stainless steel on a single production floor. In operation, the sensor housing carries the active element while passing the signal through a sealed exit. 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 draw ratio, corner radii and the faces that must stay flat, all held to the drawing and verified at first article.
The press shop and machine shop that make this metal sensor share one floor, so revisions do not wait on outside suppliers, with process data archived for repeat orders.
Production route
Manufacturing runs on a controlled process path: Parts are assembled in welding fixtures and the welds are dressed; welds are dressed flush where the drawing requires, then leak-tested.
The brushed cylinder shell tooling and setup record is stored against the part number, so nothing depends on someone remembering. The signed brushed cylinder shell sample remains the reference and is kept with the job file.
Materials and finishing
Base materials in stock: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this metal sensor runs in carbon steel or stainless.
With the working face exposed, the finish is selected for cleanliness: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. The choice is recorded on the drawing for this metal sensor, so the decision never has to be made twice.
Repeat orders are gauged back to the approved first article, so nothing changes silently between orders.
Quality control
The plant is ISO 9001 certified: certificates verify each incoming batch of material, the CMM measures the first article dimension by dimension, and every production run is inspected against the first-article report. Seal faces and threads on the brushed cylinder shell are inspected batch by batch. Tests for torque, leakage or pressure can be arranged when the service demands them, and the batch file carries the results.
Applications
The metal sensor sits in sensor and thermostat assemblies across automotive, appliance and industrial programmes.
This metal sensor is supplied to several positions in the same machine, so the specification is set by the toughest of them, and approvals carry across programmes.
Customization and options
What customers usually vary
The options most often changed on this metal sensor: wall thickness bands, flange geometry, thread call-outs and the surface finish, with orders run as prototypes, pilot lots or scheduled call-offs.
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 brushed cylinder shell quotation carries a validity period and the price is held to it.
Specifications
| Item | Temperature Sensor Housing with Double-tube Welded Flange Base |
|---|---|
| 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 | Tooling is built and held under your part number, so tooling lead time stays under our control, 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; special grades are sourced to the drawing when volumes justify. |
| Surface finish | Natural, plated or coated – the print decides, and the agreed finish is logged; the agreed finish travels with the part number. |
| Processing | Forming, fixture welding, weld dressing and inspection, then surface treatment. |
| Equipment | Deep drawing presses plus CNC turning centres for machined faces; first articles and batch samples are checked on the CMM. |
| Tolerance | +/-0.03 mm on stepped bores, concentricity per print; capability is checked on the first article before the run continues. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, payment by T/T, L/C at sight or D/P; each volume tier carries its own quoted price. |
Packaging and delivery
The finish on this metal sensor dictates how it is packed: interleaves, bags or trays are matched to the surface treatment, in sealed export cartons, palletised and marked as you direct.
