This 304 316 Stainless Steel NTC Sensor Housing with CNC Machining Precision is an Aunov Tech production part in stainless steel, quoted and built to customer print. Once installed, the sensor housing shields the sensing element and positions it in the measured medium. Forming, machining and inspection share one floor, so repeat orders stay aligned with the approved sample under one roof.
Product overview
The specification of this stainless steel sensor turns on, the draw ratio, corner radii and the faces that must stay flat, re-checked whenever the drawing is revised.
Forming, machining and finishing for this stainless steel sensor happen on one site, so the route from print to sample stays short, with process data archived for repeat orders.
How it is manufactured
Every stainless steel sensor follows the same routed path: The part is machined from bar or plate on CNC lathes and mills; tight features are held in one setup so concentricity does not depend on re-chucking.
Each stepped thermowell housing, shipment is verified against the master sample before it leaves the shop. Mill certificates are filed per heat, so stepped thermowell housing, traceability survives a change of material batch.
Materials and finishing
Everything is drawn from a fixed stock list: cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze with 304 / 316 stainless steel specified on the drawing for this stainless steel sensor.
The finish is chosen for a clean working surface: electrophoresis, powder coating, anodising and zinc / nickel plating. It is fixed on the drawing for this stainless steel sensor, so repeat orders never reopen the question.
Full stepped thermowell housing, documentation set available: material certs, dimensional reports, first article files.
Quality control
Quality management is certified to ISO 9001: stock arrivals are checked against mill certificates, a full CMM report approves the first article, and routine sampling keeps batches aligned with the first article. Each stepped thermowell housing, batch is checked for thread class and seal face condition. Where the application asks for it, torque, leak or pressure testing is added to the plan, and the inspection report ships with each batch.
Applications
The stainless steel sensor sits in thermal sensing and appliance control assemblies in volume programmes as well as aftermarket supply.
One part number for this stainless steel sensor frequently serves several assemblies, so one approved version covers the whole range, and the die does not have to change.
Customization and options
The options customers tune most
Variations that come up most often on this stainless steel sensor: material grade, wall band, flange shape, thread size and finish for the working environment, and how the order is released – sample, pilot run or scheduled call-off.
Each quote for this stainless steel sensor states which variations are already tooled, so the boundary between free and chargeable changes is explicit. Nothing is implied – on tooling, the quotation is the contract for the stepped thermowell housing,.
Specifications
| Item | 304 316 Stainless Steel NTC Sensor Housing with CNC Machining Precision |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings – non-standard features are feasibility-checked at quotation stage. |
| Tooling | Tooling is built to the drawing and held against your part number for the life of the part. |
| Samples | First-article samples ship with a dimensional report and material certificate, so the sample is retained as the master, and the signed sample is kept for future reorders. |
| Materials | Stock runs to carbon steel, 304 / 316 stainless, aluminium and brass; special grades are sourced to the drawing when volumes justify. |
| Surface finish | Plating, powder coating, anodising or polishing, per the print; the agreed finish travels with the part number. |
| 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 | +/-0.01 mm on sealing faces, +/-0.05 mm on drawn profiles; finer bands confirmed from capability data before quoting. |
| Delivery terms | CIF or DDP, with FOB available, T/T with deposit and L/C for larger runs; call-off schedules are supported. |
Packaging and delivery
Packing for this stainless steel sensor is chosen around the coating: the coating decides whether parts are interleaved, bagged or tray-packed, then cartons are sealed and palletised, with marks and documents as you specify.
