The Fuel pump electric motor components is produced by Aunov Tech from stainless steel, formed and finished under one roof. In duty, the fuel pump component seals the fuel-wetted chamber and locates the pump internals. The same floor forms, machines and inspects the part, and a design change is re-sampled in one place with no third party in the loop.
Product overview
For this metal pump, the drawing centres on, the formed envelope, flatness and hole location, each measured at first article and gauged on production batches.
Tooling and finishing for this metal pump run under one roof, so a drawing change is absorbed in one step, and nothing about the route depends on a third party.
From coil to finished part
Every metal pump follows the same routed path: Drawing runs from flat blank to finished envelope in one controlled sequence; piercing and trimming are done in the same die line.
The tooling record is stored against the part number, and a reorder is a repeat, not a new start.
Materials and surface finish
Our stock list runs to carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and the grade agreed for this metal pump is carbon steel or stainless.
The coating is matched to the working environment: plating, anodising, powder coating, electrophoresis and passivation. The agreed finish for this metal pump travels with the part number on every reorder.
Production batches are gauged to the signed first article, so material and finish stay consistent between shipments.
Quality control
The factory operates with ISO 9001 certification: material traceability starts with mill certificates, first articles are measured on a CMM, and later batches follow the sampling plan agreed at approval. For the fuel pump component, leak testing is available on request, and every first article is measured for bore finish and groove geometry. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, and the report is packed with the shipment.
Applications
You will find this metal pump inside automotive assemblies and under-hood equipment for customers who buy to drawing.
The same metal pump is used across several platforms, so the specification is set by the toughest of them, and the same first article applies throughout.
Specifications
| Item | Fuel pump electric motor components |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – a manufacturability review comes back with the quotation; the agreed version governs every later batch. |
| Tooling | Dies, fixtures and gauges are made in our own toolroom, so a die can be re-cut against the approved drawing, 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 pump. |
| 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 to +/-0.1 mm across the part; tighter bands confirmed against the die before the quotation is fixed. |
| Delivery terms | FOB Ningbo or Shanghai, T/T with deposit and L/C for larger runs; price breaks tie to annual volume. |
