Aunov Tech supplies the Warm wind motor shell as a stainless steel component manufactured entirely in house. On the product, the HVAC motor housing shields the windings while the flange mounts the motor in the air path. Die work, machining and CMM inspection are all in-house, which keeps tolerances consistent from sample to volume with no third party in the loop.
Product overview
What matters most on this metal shell is, wall thinning, concentricity and the finished mating faces, checked by CMM at first article and by gauge in production.
Die building, pressing and machining for this metal shell are all in house, which keeps the sample loop inside our own schedule, and the die record stays with your part number.
How the part is produced
This is how the metal shell is built: Coil is blanked and drawn through progressive and single-stage dies; threads are single-pointed or rolled and seats bored in one setup where possible.
Production batches of the warm wind motor are gauged back to the signed first article, not to a memory of it. The signed warm wind motor sample remains the reference and is kept with the job file.
Materials and finishing
The standard stock list carries SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze with carbon steel or stainless specified on the drawing for this metal shell.
Finish selection follows the working environment: plating, anodising, powder coating, electrophoresis and passivation. It is fixed on the drawing for this metal shell, so repeat orders never reopen the question.
Batch records for the warm wind motor are filed against the part number, so process settings are reused instead of re-invented. Any change to the warm wind motor drawing is re-approved and re-verified before production continues.
Quality control
Production runs under an ISO 9001 certified quality system: mill certificates cover every delivery of stock, the CMM measures the first article dimension by dimension, and run inspections follow an agreed sampling plan. 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, and the inspection report ships with each batch.
Typical applications
This metal shell is used in industrial and appliance assemblies across automotive, appliance and industrial programmes.
One part number for this metal shell frequently serves several assemblies, so the specification is set by the toughest of them, and the drawing stays common.
Specifications
| Item | Warm wind motor shell |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – a manufacturability review comes back with the quotation; the approved drawing is kept as the controlled master. |
| Tooling | Progressive 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. |
| Samples | Sample lead time is quoted with the order, and the approved sample governs the run. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass and copper – the grade is matched to the duty of this shell. |
| Surface finish | Natural, plated or coated – the print decides, and the agreed finish is logged; finish thickness and adhesion checked on the first article. |
| Processing | Deep drawing from coil or blank, with in-process annealing so walls thin evenly; batch records are filed so a repeat order starts from approved data. |
| Equipment | 5-250 T mechanical presses, 250-500 T hydraulic presses and annealing furnaces in line; secondary ops run on CNC turning centres, inspection on the CMM. |
| Tolerance | +/-0.05 mm on formed features, with capability data on critical dimensions; critical dimensions carry CMM data with the shipment. |
| Delivery terms | FOB, CIF or DDP per Incoterms – payment by T/T or L/C, with shipping quoted door-to-door. |
