Produced in stainless steel by Aunov Tech, the Air conditioner DC motor housing – deep drawn is formed and machined on the same floor. In service, the HVAC motor housing shields the windings while the flange mounts the motor in the air path. Forming, machining and inspection share one floor, keeping first-article quality through scheduled runs under one roof.
Product overview
What defines this metal housing is, the forming route, the tolerance band and the sealing faces, all held to the drawing and verified at first article.
The whole route from die to finished metal housing stays in house, so a drawing change is absorbed in one step, with process data archived for repeat orders.
From coil to finished part
This is how the metal housing is built: The shell starts as coil or blank and is drawn through single and progressive dies; flanges and rims are formed in the same line, then trimmed to length.
Process settings are archived with the part number, so reorders match the samples you already approved.
Materials and finishing
Our stock list runs to SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this metal housing is costed in carbon steel or stainless.
The finish is chosen for the duty it will see: polishing, zinc / nickel / chrome plating, anodising or powder coating. It is written into the drawing for this metal housing, so it cannot drift between batches.
The approved sample governs later runs, with mill certificates filed per heat.
Quality control
Quality management is certified to ISO 9001: stock arrivals are checked against mill certificates, first-article geometry is confirmed on the CMM, and production batches are inspected on a sampling plan. 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 results travel with the batch paperwork.
Applications
This metal housing normally works inside industrial and appliance assemblies for customers who own the drawing and the tooling.
Drawings for this metal housing are adapted across programmes, so wall bands and finishes are selected to cover the widest duty, and the drawing stays common.
Specifications
| Item | Air conditioner DC motor housing – deep drawn |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – unusual walls, threads or tolerances are feasibility-checked first; the approved drawing is kept as the controlled master. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so the die charge appears as its own quotation line, and maintenance is tracked against the part number. |
| Samples | Prototype and pre-production samples are provided against the drawing, so the approved first article becomes the gauge reference, and later batches are gauged back to the signed sample. |
| 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 | Blanking, multi-stage deep drawing with interstage annealing, trimming and piercing, coining, then finishing. |
| Equipment | Mechanical presses from 5 to 250 T, hydraulic presses 250-500 T, annealing ovens, plus CNC turning and machining centres. |
| Tolerance | +/-0.1 mm to +/-0.2 mm general; critical features held to the drawing and verified on the first article. |
| Delivery terms | CIF or DDP, with FOB available, T/T or L/C, with D/P accepted on repeat business; call-off schedules are supported. |
