Stainless Multi-Step Drawn Sensor Sleeve

This Thermostat Temperature Controller Switch Module NTC Sensor Probes is an Aunov Tech production part in stainless steel, quoted and built to customer print. In service, the sensor housing shields the sensing element and positions it in the measured medium. Drawing, cutting and measurement sit on one floor, and a design change is re-sampled in one place under one roof.

Product overview

For this metal sensor, the drawing centres on, wall thinning, concentricity and the finished mating faces, re-checked whenever the drawing is revised.

Die building, pressing and machining for this metal sensor are all in house, which keeps the sample loop inside our own schedule, and the same die can be re-cut from the original data.

Production route

The process for this metal sensor runs in a fixed sequence: Coil is blanked and drawn through progressive and single-stage dies; piercing and trimming are done in the same die line.

Each multi-step sensor sleeve shipment is verified against the master sample before it leaves the shop. Mill certificates are filed per heat, so multi-step sensor sleeve traceability survives a change of material batch.

Materials and finishing

Materials kept on the floor cover carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper with this metal sensor costed in carbon steel or stainless.

Because the part works in contact with media, the coating is chosen for cleanliness: plating, anodising, powder coating, electrophoresis and passivation. The choice is recorded on the drawing for this metal sensor, so the decision never has to be made twice.

Each multi-step sensor sleeve shipment is verified against the master sample before it leaves the shop. The approved multi-step sensor sleeve sample governs later runs, and any grade change is agreed in writing first.

Quality control and inspection

An ISO 9001 certified system governs production: incoming material is verified against mill certificates, a full CMM report approves the first article, and run inspections follow an agreed sampling plan. Thread gauging and seal-face checks are part of every multi-step sensor sleeve batch. Where the application asks for it, torque, leak or pressure testing is added to the plan, and the report is packed with the shipment.

Applications

Typical installation of the metal sensor is in thermal sensing and appliance control assemblies across automotive, appliance and industrial programmes.

The same metal sensor is often run in more than one assembly, so the specification is set by the toughest of them, and the same first article applies throughout.

Customization and options

Options that vary most in this multi-step sensor sleeve family

The options most often changed on this metal sensor: material grade, coating, wall bands, flange form and end closure, and the batch pattern – prototype, pilot lot or scheduled production.

Options for this metal sensor already covered by the die are shown on the quote, so there are no surprise tooling charges after approval. The multi-step sensor sleeve quotation records who owns the tooling.

DesigningDFM feedback accompanies the quotation, so surprises are caught before the die is cut.
ToolingProgressive and drawing dies are designed and built in house, so the die charge appears as its own quotation line, and the charge is refundable against agreed volumes.
SamplesSample lead time is quoted with the order, and the approved sample governs the run.
MaterialsCarbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass are held on site; mill certificates and heat numbers accompany the first article.
Surface finishZinc, nickel or chrome plating, anodising, passivation or e-coat; alternatives quoted with the quotation, samples approved in writing.
ProcessingDrawn shell with machined seats and threads where the print calls for them; batch records are filed so a repeat order starts from approved data.
EquipmentDeep drawing presses plus CNC turning centres for machined faces, with in-house toolmaking to keep dies and fixtures maintained.
Tolerance+/-0.03 mm on stepped bores, concentricity per print; dimensional reports accompany the first article.
Delivery termsFOB, CIF or DDP per Incoterms 2020, payment by T/T or L/C, quoted in USD or EUR; each volume tier carries its own quoted price.

Packaging and delivery

Packaging protects the finished surfaces of this metal sensor: interleaves, polybags or formed trays are selected according to the coating, in sealed cartons on export pallets; shipping documents and carton marks follow your instructions.
