This Deep drawn sensor housing is an Aunov Tech production part in stainless steel, quoted and built to customer print. In service, the sensor housing carries the active element while passing the signal through a sealed exit. Die work, machining and CMM inspection are all in-house, so first-article dimensions hold through volume batches on one production route.
Product overview
This metal sensor is defined by, material grade, wall uniformity and thread position, recorded on the inspection report for every batch.
Die work and machining for this metal sensor sit on the same floor, so a drawing change is absorbed in one step, with the tooling history retained in house.
How it is manufactured
Manufacturing runs on a controlled process path: The drawn envelope is produced in stages with anneals between them; wall thickness is checked at the thinnest section after forming.
Each sensor housing shipment is verified against the master sample before it leaves the shop. Any change to the sensor housing drawing is re-approved and re-verified before production continues.
Materials and surface finish
Materials kept on the floor cover carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this metal sensor runs in carbon steel or stainless.
Because the part works in contact with media, the coating is chosen for cleanliness: zinc and nickel plating, chrome, anodising, powder coating and passivation. The finish on this metal sensor is locked to the drawing revision, so later orders match.
Repeat sensor housing orders are measured against the approved sample, so neither material nor finish drifts between lots. The approved sensor housing sample governs later runs, and any grade change is agreed in writing first.
Quality control and inspection
Production runs under an ISO 9001 certified quality system: incoming material is verified against mill certificates, first articles are measured on a CMM, and every production run is inspected against the first-article report. The sensor housing batch record includes thread gauging and seal face inspection. Where the application asks for it, torque, leak or pressure testing is added to the plan, and the batch file carries the results.
Typical applications
Typical installation of the metal sensor is in thermal sensing and appliance control assemblies in volume programmes as well as aftermarket supply.
A single design of this metal sensor is often reused across a product family, so the tightest tolerance in the family sets the spec, and no re-tooling is needed.
Specifications
| Item | Deep drawn sensor housing |
|---|---|
| Brand | AUNOV |
| Designing | Design intent is read from the print, and any conflict in the drawing is raised before quoting. |
| Tooling | Progressive and drawing dies are designed and built in house, so die cost stays transparent, and maintenance is tracked against the part number. |
| Samples | Sample and first article are the same discipline here: measured, reported, then approved. |
| Materials | Standard stock: carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass; grade and temper are confirmed in writing before tooling. |
| Surface finish | Plating, coating or polishing to suit the drawing; alternatives quoted with the quotation, samples approved in writing. |
| Processing | Deep drawing followed by CNC finishing on critical faces; first articles verify the whole flow before the run is released. |
| Equipment | Deep 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; critical dimensions carry CMM data with the shipment. |
| Delivery terms | FOB Ningbo or Shanghai, T/T with deposit and L/C for larger runs; call-off schedules are supported. |
