Produced in stainless steel by Aunov Tech, the 300Series Protection Thermowell Multiple Shape Tapered Tube Closed End is formed and machined on the same floor. In operation, the deep drawn tube provides a sealed cylindrical body the assembly builds into. Die work, machining and CMM inspection are all in-house, keeping first-article quality through scheduled runs with no third party in the loop.
Product overview
This metal tube is defined by, wall thickness control, flange geometry and the sealing surface, each measured at first article and gauged on production batches.
Forming, machining and finishing for this metal tube happen on one site, which keeps revision loops short and samples fast, and the approved sample is kept as the master.
How it is manufactured
Manufacturing runs on a controlled process path: Drawing converts a flat blank into the finished envelope in one controlled sequence; piercing and trimming are done in the same die line.
Process settings are archived with the part number, and the same setup is reused on the next call-off.
Materials and surface finish
Everything is drawn from a fixed stock list: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this metal tube is costed in carbon steel or stainless.
The finish is chosen for the duty it will see: plating, anodising, powder coating, electrophoresis and passivation. The choice is recorded on the drawing for this metal tube, so the decision never has to be made twice.
The approved sample governs later runs, with mill certificates filed per heat.
Quality control
Production runs under an ISO 9001 certified quality system: stock arrivals are checked against mill certificates, the CMM measures the first article dimension by dimension, and every production run is inspected against the first-article report. Wall thickness on the perforated stepped thermowell is checked at first article, not assumed. Tests for torque, leakage or pressure can be arranged when the service demands them, and the inspection report ships with each batch.
Applications
This metal tube normally works inside industrial equipment and general assembly work for OEM and Tier-1 customers.
A single design of this metal tube is often reused across a product family, so the finish is chosen to cover the harshest of them, without a second tooling round.
Customization and options
Where designs usually differ
The parts of the print for this metal tube that get adjusted: material and coating for the duty, wall bands, flange forms, threads and bosses, closed ends and finishes matched to the working environment, with orders run as prototypes, pilot lots or scheduled call-offs.
Quotes for this metal tube show which options the current die already supports, so you can see which options are free and which need new tooling. Each perforated stepped thermowell reorder is priced with the original split.
Specifications
| Item | 300Series Protection Thermowell Multiple Shape Tapered Tube Closed End |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – samples are reverse-measured into a controlled drawing; changes are priced before they are made. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so no tooling step is outsourced, and maintenance is tracked against the part number. |
| 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 (SPCC / DC01), 304 / 316 stainless, aluminium, brass and copper – the grade is matched to the duty of this tube. |
| Surface finish | Plating, powder coating, anodising or polishing, per the print; masking and laser marking available where needed. |
| Processing | Tube drawing, straightening and turning in one flow; every stage is logged against your part number. |
| Equipment | Drawn-tube benches, in-line annealing and CNC turning; secondary ops run on CNC turning centres, inspection on the CMM. |
| Tolerance | +/-0.02 mm on fitted diameters, +/-0.1 mm on formed ends; capability is checked on the first article before the run continues. |
| Delivery terms | FOB, with DDP offered for EU and US addresses, payment by T/T or L/C, quoted in USD or EUR; call-off schedules are supported. |
Packaging and delivery
Packing for this metal tube is chosen around the coating: interleaves, polybags or formed trays are selected according to the coating, then sealed cartons are palletised for export, with documents and marks to your instruction.
