Aunov Tech manufactures the Electric Warm Wind Motor Housing in stainless steel on a single production floor. In service, the HVAC motor housing locates the fan or wheel on the motor shaft through the machined bore. The same floor forms, machines and inspects the part, so repeat orders stay aligned with the approved sample without re-quoting the job elsewhere.
Product overview
What matters most on this metal housing is, the forming route, the tolerance band and the sealing faces, checked by CMM at first article and by gauge in production.
Die building, pressing and machining for this metal housing are all in house, so the route from print to sample stays short, and nothing about the route depends on a third party.
From coil to finished part
This is how the metal housing is built: Blanks are drawn in stages, with interstage annealing where the wall thins; wall thickness is checked at the thinnest section after forming.
Route cards follow every order through the shop, and the same setup is reused on the next call-off.
Materials and finishing
Everything is drawn from a fixed stock list: carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this metal housing is costed in carbon steel or stainless.
Finish selection follows the working environment: polishing, zinc / nickel / chrome plating, anodising or powder coating. The agreed finish for this metal housing travels with the part number on every reorder.
Each shipment is verified against the master sample, and material certificates are kept per batch.
Quality control
The factory operates with ISO 9001 certification: 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. For the HVAC motor housing, shaft-bore runout is measured at first article, and salt-spray testing backs the coating choice for wet locations. Functional testing – torque, leak or pressure – can be written into the plan, with certificates included in the shipment file.
Applications
This metal housing is used in industrial and appliance assemblies for customers who own the drawing and the tooling.
Drawings for this metal housing are adapted across programmes, so one approved version covers the whole range, and no re-tooling is needed.
Specifications
| Item | Electric Warm Wind Motor Housing |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – samples are reverse-measured into a controlled drawing; the agreed version governs every later batch. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so a die can be re-cut against the approved drawing, and ownership is confirmed on the quotation. |
| Samples | Pre-production samples come with a full inspection report, so the part is proven before it is made in volume, 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 housing. |
| Surface finish | Zinc / nickel / chrome plating or e-coat, chosen for the environment this housing sees; salt-spray tested to drawing. |
| Processing | Deep drawing from coil or blank, with in-process annealing so walls thin evenly; trim, pierce, form and finish. |
| Equipment | 5-250 T mechanical presses and 250-500 T hydraulic presses, in-line annealing furnace, CNC turning for secondary work. |
| Tolerance | +/-0.1 mm to +/-0.2 mm general; critical features held to the drawing and verified on the first article. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, T/T or L/C, with D/P accepted on repeat business; repeat orders reuse the approved first article. |
