The Sheet metal deep drawing stepping motor housing is produced by Aunov Tech from stainless steel, formed and finished under one roof. Once installed, the drawn housing shields the assembly from dust, moisture and handling while locating it in place. Forming and machining share equipment, staff and batch records, and a design change is re-sampled in one place with no third party in the loop.
Product overview
What defines this metal housing is, draw depth, wall band and the surfaces that forming cannot hold, each measured at first article and gauged on production batches.
Die building, pressing and machining for this metal housing are all in house, so a change of wall or hole does not restart the programme, and every step is logged against the part number.
How it is manufactured
Every metal housing follows the same routed path: The shell starts as coil or blank and is drawn through single and progressive dies; wall thickness is checked at the thinnest section after forming.
Batch records are filed against the part number, and a reorder is a repeat, not a new start.
Materials and surface finish
Working stock covers carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this metal housing runs in carbon steel or stainless.
Coating and polishing are matched to the end use: electrophoresis, powder coating, anodising and zinc / nickel plating. The finish on this metal housing is locked to the drawing revision, so later orders match.
Production batches are gauged to the signed first article, so the colour and grain of the finish stay stable.
Quality control
The plant is ISO 9001 certified: certificates verify each incoming batch of material, first articles are measured on a CMM, and production batches are inspected on a sampling plan. Part-specific checks apply as well: on the drawn housing, cavity depth and seal-face finish are measured at first article, and leak testing is available for sealed duty. Where the application asks for it, torque, leak or pressure testing is added to the plan, with certificates included in the shipment file.
Applications
You will find this metal housing inside industrial and appliance assemblies in both OEM and aftermarket supply.
One drawing for this metal housing is commonly applied to several programmes, so a single grade and coating can cover each application, and no re-tooling is needed.
Specifications
| Item | Sheet metal deep drawing stepping motor housing |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – samples are reverse-measured into a controlled drawing; the approved drawing is kept as the controlled master. |
| Tooling | Progressive and drawing dies are designed and built in house, so die cost stays transparent, and the charge is refundable against agreed volumes. |
| Samples | Prototype and pre-production samples are provided against the drawing, so the part is proven before it is made in volume, and later batches are gauged back to the signed sample. |
| Materials | Stock covers carbon steel, 304 / 316 stainless, aluminium and brass; the final grade is fixed with the drawing review. |
| Surface finish | Zinc or nickel plating for corrosion, plus powder coating or electrophoresis on housings; laser etching on request. |
| 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 on formed features and +/-0.2 mm on overall lengths; tighter bands confirmed against the die before quoting. |
| Delivery terms | FOB, with DDP offered for EU and US addresses, payment by T/T or L/C, quoted in USD or EUR; call-off schedules are supported. |
