Aunov Tech supplies the Air conditioner copper sleeve 5K 10K 15K 20K 50K NTC temperature sensor as a copper component manufactured entirely in house. In operation, the HVAC motor housing shields the windings while the flange mounts the motor in the air path. One production floor covers forming, finishing and inspection, so repeat orders stay aligned with the approved sample without handing the part to another vendor.
Product overview
What defines this copper sensor is, material grade, wall uniformity and thread position, recorded on the inspection report for every batch.
The whole route from die to finished copper sensor stays in house, so a change of wall or hole does not restart the programme, and nothing about the route depends on a third party.
How it is manufactured
Manufacturing runs on a controlled process path: Drawing converts a flat blank into the finished envelope in one controlled sequence; after drawing, critical faces are machined and the part is degreased and gauged.
Route cards follow each sleeve batch through the shop, so the next run starts from the data that already worked. The approved sleeve sample governs later runs, and any grade change is agreed in writing first.
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 copper sensor runs in T2 copper.
With the working face exposed, the finish is selected for cleanliness: plating, anodising, powder coating, electrophoresis and passivation. It is fixed on the drawing for this copper sensor, so repeat orders never reopen the question.
Repeat sleeve orders are measured against the approved sample, so neither material nor finish drifts between lots. Any change to the sleeve drawing is re-approved and re-verified before production continues.
Quality control and inspection
Quality management is certified to ISO 9001: 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. At HVAC motor housing level, shaft-bore runout is measured at first article, and salt-spray testing backs the coating choice for wet locations. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, and the batch file carries the results.
Applications
This copper sensor is used in temperature sensing and control assemblies for customers who buy to drawing.
The same copper sensor is often run in more than one assembly, so the finish is chosen to cover the harshest of them, and the drawing stays common.
Options and variations
What customers usually vary
Customer choices typically cover material (carbon steel, stainless, aluminum, brass), surface treatment, vent-hole patterns, closed or open yokes, drain slots, mounting variants and corrosion-resistant coatings, and order shape – prototype lots first, scheduled volumes after approval.
Each variation is priced with its tooling effect made visible, so you can see which options are free and which need new tooling.
Specifications
| Item | Air conditioner copper sleeve 5K 10K 15K 20K 50K NTC temperature sensor |
|---|---|
| Brand | AUNOV |
| Designing | The drawing is reviewed first; the agreed version then governs every batch. |
| Tooling | Because tooling is in house, changes to the part can be trialled without waiting on a third party. |
| Samples | Prototype and pre-production samples are provided against the drawing, so any deviation is corrected at sample stage, and mass production is gated on that approval. |
| Materials | T2 / T3 copper and H62 brass, 0.8-4.0 mm; soft tempers for deep forming, hard tempers where stiffness matters. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; alternatives quoted with the quotation, samples approved in writing. |
| 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, backed by CNC turning centres and a climate-controlled inspection room. |
| Tolerance | +/-0.02 mm on turned diameters, wall held to the agreed band; dimensional reports accompany the first article. |
| Delivery terms | Incoterms FOB as standard with DDP on request; sea and air options priced with the order. |
Packaging and delivery
Packing for this copper sensor is chosen around the coating: each coating gets its own packing – interleaves, bags or trays, in sealed export cartons, palletised and marked as you direct.
