The Electric Warm Wind Motor Casing is produced by Aunov Tech from stainless steel, formed and finished under one roof. 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 first-article dimensions hold through volume batches without a second supplier involved.
Product overview
What matters most on this metal casing is, the formed envelope, flatness and hole location, controlled from the approved first article onward.
Toolroom, presses and machining centres used on this metal casing operate on the same site, so revisions do not wait on outside suppliers, and every step is logged against the part number.
How it is manufactured
This is how the metal casing is built: Blanks are drawn in stages, with interstage annealing where the wall thins; the finishing operations hold the concentricity the drawing calls for.
Every electric warm wind order keeps its trace back to the approved first article, and a reorder is a repeat rather than a new start. Mill certificates are filed per heat, so electric warm wind traceability survives a change of material batch.
Materials and finishing
Our stock list runs to cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and the grade agreed for this metal casing is carbon steel or stainless.
The finish is chosen for the duty it will see: plating, anodising, powder coating, electrophoresis and passivation. It is written into the drawing for this metal casing, so it cannot drift between batches.
Repeat electric warm wind orders are measured against the approved sample, so neither material nor finish drifts between lots. The approved electric warm wind sample governs later runs, and any grade change is agreed in writing first.
Quality control
The plant is ISO 9001 certified: certificates verify each incoming batch of material, first articles are measured on a CMM, and later batches follow the sampling plan agreed at approval. On the HVAC motor housing itself, 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 report is packed with the shipment.
Applications
This metal casing is used in industrial and appliance assemblies under schedules that run for years at a time.
Drawings for this metal casing are adapted across programmes, so the tightest tolerance in the family sets the spec, and approvals carry across programmes.
Specifications
| Item | Electric Warm Wind Motor Casing |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – a manufacturability review comes back with the quotation; changes are priced before they are made. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so die cost stays transparent, and ownership is confirmed on the quotation. |
| Samples | Samples are produced on the production tooling, so what you approve is what you get. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass and copper – the grade is matched to the duty of this casing. |
| Surface finish | Surface treatment matched to the duty: plating, coating or polishing; finish thickness and adhesion checked on the first article. |
| Processing | Coil blanking and progressive drawing, coining on the final station where the print calls for it; in-process checks sit between stages, not only at the end. |
| Equipment | Mechanical presses 5-250 T plus 250-500 T hydraulics, with in-line annealing; secondary ops run on CNC turning centres, inspection on the CMM. |
| Tolerance | +/-0.05 mm on formed features, with capability data on critical dimensions; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | FOB, with DDP offered for EU and US addresses, T/T or L/C, with D/P accepted on repeat business; repeat orders reuse the approved first article. |
