Aunov Tech supplies the Oil pump electric motor housing as a stainless steel component manufactured entirely in house. In duty, the drawn housing encloses the sensitive internals and carries the mounting interface. Forming and machining share equipment, staff and batch records, which keeps tolerances consistent from sample to volume on one production route.
Product overview
For this metal housing, the drawing centres on, the draw ratio, corner radii and the faces that must stay flat, controlled from the approved first article onward.
The press shop and machine shop that make this metal housing share one floor, so revisions do not wait on outside suppliers, and nothing about the route depends on a third party.
How it is manufactured
Every metal housing follows the same routed path: Coil is blanked and drawn through progressive and single-stage dies; flanges and rims are formed in the same line, then trimmed to length.
Each shipment is traceable to the signed first article, and that record is what every reorder is built from.
Materials and finishing
Everything is drawn from a fixed stock list: cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze with carbon steel or stainless specified on the drawing for this metal housing.
Coating selection follows the duty – indoor, outdoor or under-hood: polishing, plating in zinc, nickel or chrome, anodising, powder coating, electrophoresis and passivation. The finish on this metal housing is locked to the drawing revision, so later orders match.
Each shipment is verified against the master sample, so the colour and grain of the finish stay stable.
Quality control
Quality management is certified to ISO 9001: material traceability starts with mill certificates, a full CMM report approves the first article, and run inspections follow an agreed sampling plan. On the drawn housing itself, cavity depth and seal-face finish are measured at first article, and leak testing is available for sealed duty. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, with certificates included in the shipment file.
Where the part is used
You will find this metal housing inside pumps, valves and hydraulic equipment for OEM and Tier-1 customers.
The same metal housing is used across several platforms, so a single grade and coating can cover each application, and no re-tooling is needed.
Specifications
| Item | Oil pump electric motor housing |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – DFM notes are returned before any tooling is cut; changes are priced before they are made. |
| Tooling | Tooling is built and held under your part number, so no tooling step is outsourced, and first-article timing is measured from the tooling start date. |
| Samples | Prototype and pre-production samples are provided against the drawing, so any deviation is corrected at sample stage, 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 | 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, payment by T/T or L/C, quoted in USD or EUR; price breaks tie to annual volume. |
