Aunov Tech manufactures the 304 316 Stainless steel ntc sensor housing for temperature sensor in stainless steel on a single production floor. On the product, the sensor housing shields the sensing element and positions it in the measured medium. Forming and machining share equipment, staff and batch records, so the approved sample defines every later batch on one production route.
Product overview
This stainless steel sensor is defined by, draw depth, wall band and the surfaces that forming cannot hold, all held to the drawing and verified at first article.
Forming, machining and finishing for this stainless steel sensor happen on one site, so revisions do not wait on outside suppliers, and the approved sample is kept as the master.
From coil to finished part
Production follows a defined route: The shell starts as coil or blank and is drawn through single and progressive dies; the part is annealed between stages so the wall thins evenly.
Batch records for the stepped sensor sleeve are filed against the part number, so process settings are reused instead of re-invented. The approved stepped sensor sleeve sample governs later runs, and any grade change is agreed in writing first.
Materials and finishing
The standard stock list carries cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and this stainless steel sensor runs in 304 / 316 stainless steel.
With the working face exposed, the finish is selected for cleanliness: electrophoresis, powder coating, anodising and zinc / nickel plating. It is written into the drawing for this stainless steel sensor, so it cannot drift between batches.
The stepped sensor sleeve manufacturing record is archived together with the drawing revision that produced it. Deviations on the stepped sensor sleeve are reported before shipment rather than found on your assembly line.
Quality control
The factory operates with ISO 9001 certification: 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. Each stepped sensor sleeve batch is checked for thread class and seal face condition. Functional testing – torque, leak or pressure – can be written into the plan, with certificates included in the shipment file.
Typical applications
The stainless steel sensor sits in sensor and thermostat assemblies under schedules that run for years at a time.
The same stainless steel sensor is often run in more than one assembly, so the tightest tolerance in the family sets the spec, and the die does not have to change.
Options and variations
What customers usually vary
Design freedom covers material (carbon steel, stainless, aluminum, brass), the finish for the environment, thread classes, hex or flange mounting, sealed cable exits, vent holes and finishes matched to the measured medium, and lot sizing from prototypes to call-off.
Changes are quoted with their tooling impact stated explicitly, keeping the trade-offs visible from the start.
Specifications
| Item | 304 316 Stainless steel ntc sensor housing for temperature sensor |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – unusual walls, threads or tolerances are feasibility-checked first; the agreed version governs every later batch. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so a die can be re-cut against the approved drawing, and maintenance is tracked against the part number. |
| Samples | Sample parts are measured and reported before submission, so any deviation is corrected at sample stage. |
| Materials | Carbon steel, 304 / 316 stainless, aluminium and brass are all held in stock; material substitutes are proposed only with your written approval. |
| Surface finish | Plating, coating or polishing to suit the drawing; 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 sealing faces, +/-0.05 mm on drawn profiles; finer bands confirmed from capability data before quoting. |
| Delivery terms | FOB Ningbo or Shanghai, payment by T/T, L/C at sight or D/P; repeat orders reuse the approved first article. |
Packing and shipment
This stainless steel sensor is packed to protect the finish: interleaving, individual bags or trays are chosen by finish type, in sealed cartons on export pallets, with documents issued to your instructions.
