The Deep drawing tube ntc stainless steel end closed tube sensor probe is produced by Aunov Tech from stainless steel, formed and finished under one roof. In service, the sensor housing protects the electronics from vibration, fluid and electromagnetic noise. Forming and machining share equipment, staff and batch records, which keeps tolerances consistent from sample to volume with no third party in the loop.
Product overview
What matters most on this stainless steel sensor is, draw depth, wall band and the surfaces that forming cannot hold, controlled from the approved first article onward.
Toolroom, presses and machining centres used on this stainless steel sensor operate on the same site, so a change of wall or hole does not restart the programme, with process data archived for repeat orders.
How the part is produced
Production of this stainless steel sensor is locked to one route: The shell starts as coil or blank and is drawn through single and progressive dies; threads are single-pointed or rolled and seats bored in one setup where possible.
Every thin-wall open tubes, order keeps its trace back to the approved first article, and a reorder is a repeat rather than a new start. Mill certificates are filed per heat, so thin-wall open tubes, 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 and this stainless steel sensor runs in 304 / 316 stainless steel.
Because the part works in contact with media, the coating is chosen for cleanliness: polishing, zinc / nickel / chrome plating, anodising or powder coating. Once approved, the finish for this stainless steel sensor is fixed and does not get re-decided.
Production is compared with the approved sample every run, so neither material nor finish drifts between lots.
Quality control
Quality management is certified to ISO 9001: certificates verify each incoming batch of material, a full CMM report approves the first article, and run inspections follow an agreed sampling plan. Each thin-wall open tubes, batch is checked for thread class and seal face condition. Functional testing – torque, leak or pressure – can be written into the plan, and the batch file carries the results.
Applications
This stainless steel sensor is used in temperature sensing and control assemblies in both OEM and aftermarket supply.
One part number for this stainless steel sensor frequently serves several assemblies, so one approved version covers the whole range, and approvals carry across programmes.
Customization and options
Options changed most often
The options most often changed on this stainless steel sensor: grade and finish for the environment, wall thickness bands, flange and rim forms, threads, bosses and closed ends, and how the order is released – sample, pilot run or scheduled call-off.
The quotation for this stainless steel sensor is explicit about what the die already covers, so you are not charged twice for a feature the die already makes. The thin-wall open tubes, is frozen against the current revision until a written change is raised.
Specifications
| Item | Deep drawing tube ntc stainless steel end closed tube sensor probe |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – DFM notes are returned before any tooling is cut; the approved drawing is kept as the controlled master. |
| Tooling | Progressive and drawing dies are designed and built in house, so tooling lead time stays under our control, and first-article timing is measured from the tooling start date. |
| Samples | First-article samples ship with a dimensional report and material certificate, so any deviation is corrected at sample stage, and mass production is gated on that approval. |
| 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 | Finish selected from the drawing: plating, coating, anodising or passivation; masking and laser marking available where needed. |
| Processing | Tube drawing with precision turning on critical diameters; first articles verify the whole flow before the run is released. |
| Equipment | Tube drawing lines with annealing and finish-turning cells, backed by CNC turning centres and a climate-controlled inspection room. |
| Tolerance | +/-0.02 mm on fitted diameters, +/-0.1 mm on formed ends; dimensional reports accompany the first article. |
| Delivery terms | FOB Ningbo or Shanghai, T/T with deposit and L/C for larger runs; price breaks tie to annual volume. |
Packing and shipment
The finish on this stainless steel sensor dictates how it is packed: each coating gets its own packing – interleaves, bags or trays, then sealed cartons are palletised for export, with documents and marks to your instruction.
