Aunov Tech builds this Fuel pump electric motor casing in stainless steel, from coil or bar through to the finished surfaces. In service, the fuel pump component seals the fuel-wetted chamber and locates the pump internals. The same floor forms, machines and inspects the part, keeping first-article quality through scheduled runs without handing the part to another vendor.
Product overview
What defines this metal casing is, wall thickness control, flange geometry and the sealing surface, re-checked whenever the drawing is revised.
The press shop and machine shop that make this metal casing share one floor, which keeps revision loops short and samples fast, and the approved sample is kept as the master.
How it is manufactured
Manufacturing runs on a controlled process path: Coil is blanked and then drawn down in successive stages; the finishing operations hold the concentricity the drawing calls for.
Process settings are archived with the part number, so nothing depends on the operator remembering.
Materials and finishing
Base materials in stock: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this metal casing runs in carbon steel or stainless.
The finish is chosen for the environment the part sees: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. It is fixed on the drawing for this metal casing, so repeat orders never reopen the question.
Repeat orders are gauged back to the approved first article, so nothing changes silently between orders.
Quality control
The factory operates with ISO 9001 certification: mill certificates cover every delivery of stock, first-article geometry is confirmed on the CMM, and routine sampling keeps batches aligned with the first article. For the fuel pump component, leak testing is available on request, and every first article is measured for bore finish and groove geometry. Functional testing – torque, leak or pressure – can be written into the plan, and the inspection report ships with each batch.
Applications
Typical installation of the metal casing is in vehicle and under-bonnet assemblies in volume programmes as well as aftermarket supply.
Drawings for this metal casing are adapted across programmes, so the tightest tolerance in the family sets the spec, and the same first article applies throughout.
Specifications
| Item | Fuel pump electric motor casing |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – samples are reverse-measured into a controlled drawing; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so the die charge appears as its own quotation line, and the charge is refundable against agreed volumes. |
| Samples | Samples are issued for approval before the run, so the part is proven before it is made in volume, and the signed sample is kept for future reorders. |
| Materials | Stock covers carbon steel, 304 / 316 stainless, aluminium and brass; the final grade is fixed with the drawing review. |
| Surface finish | Zinc / nickel / chrome plating or e-coat, chosen for the environment this housing sees; salt-spray tested to drawing. |
| Processing | Deep drawing from coil or blank, with in-process annealing so walls thin evenly; trim, pierce, form and finish. |
| Equipment | Mechanical presses from 5 to 250 T, hydraulic presses 250-500 T, annealing ovens, plus CNC turning and machining centres. |
| Tolerance | +/-0.05 mm on controlled dimensions and +/-0.1 mm on general features; capability studies supplied on request. |
| Delivery terms | CIF or DDP, with FOB available, payment by T/T or L/C, quoted in USD or EUR; repeat orders reuse the approved first article. |
