Aunov Tech manufactures the S304 316 316L Temperature Sensor Thermocouple 304 Stainless Steel in stainless steel on a single production floor. Once installed, the sensor housing protects the electronics from vibration, fluid and electromagnetic noise. Die work, machining and CMM inspection are all in-house, keeping first-article quality through scheduled runs without a second supplier involved.
Product overview
This stainless steel sensor is defined by, the draw ratio, corner radii and the faces that must stay flat, re-checked whenever the drawing is revised.
Tooling and finishing for this stainless steel sensor run under one roof, so feasibility questions are answered on the shop floor, and the same die can be re-cut from the original data.
How it is manufactured
Manufacturing runs on a controlled process path: Coil is blanked and then drawn down in successive stages; after drawing, critical faces are machined and the part is degreased and gauged.
The thick-wall open cylinder manufacturing record is archived together with the drawing revision that produced it. The approved thick-wall open cylinder sample governs later runs, and any grade change is agreed in writing first.
Materials and finishing
Our stock list runs to 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.
Because the part works in contact with media, the coating is chosen for cleanliness: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. It is fixed on the drawing for this stainless steel sensor, so repeat orders never reopen the question.

Quality control
The factory operates with ISO 9001 certification: stock arrivals are checked against mill certificates, first-article geometry is confirmed on the CMM, and run inspections follow an agreed sampling plan. On the thick-wall open cylinder, thread gauging and seal face inspection run on every batch. Torque, leak and pressure tests are available where the assembly needs them, and the report is packed with the shipment.
Applications
The stainless steel sensor is specified into sensor and thermostat assemblies for OEM and Tier-1 customers.
A single design of this stainless steel sensor is often reused across a product family, so one approved version covers the whole range, without a second tooling round.
Customization and options
What customers usually vary
Typical decisions customers make 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 there are no surprise tooling charges after approval. Quantities and price breaks appear together on the thick-wall open cylinder quote.
Specifications
| Item | S304 316 316L Temperature Sensor Thermocouple 304 Stainless Steel |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – a manufacturability review comes back with the quotation; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Dies are made and maintained in house, which keeps tooling lead time and cost under control. |
| Samples | Pre-production samples come with a full inspection report, so the approved first article becomes the gauge reference, and production starts only after your written sign-off. |
| Materials | Carbon steel, 304 / 316 stainless, aluminium and brass are all held in stock; mill certificates and heat numbers accompany the first article. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; finish thickness and adhesion checked on the first article. |
| 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 | Deep drawing presses plus CNC turning centres for machined faces; first articles and batch samples are checked on the CMM. |
| Tolerance | +/-0.01 mm on sealing faces, +/-0.05 mm on drawn profiles; dimensional reports accompany the first article. |
| Delivery terms | FOB Ningbo or Shanghai, payment by T/T, L/C at sight or D/P; call-off schedules are supported. |
Packing and shipment
The packing method protects the surfaces of this stainless steel sensor: interleaving, bagging or tray packing is matched to the surface, then sealed cartons are palletised for export, with documents and marks to your instruction.
