Aunov Tech manufactures the Deep Drawn Fuel Pump Cover with Fittings in stainless steel on a single production floor. In duty, the fuel pump component carries the inlet and outlet geometry for the fuel module. Drawing, cutting and measurement sit on one floor, so repeat orders stay aligned with the approved sample with no third party in the loop.
Product overview
What defines this metal fitting is, the formed envelope, flatness and hole location, recorded on the inspection report for every batch.
Die building, pressing and machining for this metal fitting are all in house, which keeps revision loops short and samples fast, and nothing about the route depends on a third party.
How it is manufactured
Production follows a defined route: The drawn envelope is produced in stages with anneals between them; piercing and trimming are done in the same die line.
The fuel pump cover manufacturing record is archived together with the drawing revision that produced it. Deviations on the fuel pump cover are reported before shipment rather than found on your assembly line.
Materials and finishing
Everything is drawn from a fixed stock list: cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and the grade agreed for this metal fitting is carbon steel or stainless.
The coating is matched to the working environment: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. Once approved, the finish for this metal fitting is fixed and does not get re-decided.
The fuel pump cover manufacturing record is archived together with the drawing revision that produced it. Any change to the fuel pump cover drawing is re-approved and re-verified before production continues.
Quality control and inspection
Quality management is certified to ISO 9001: stock arrivals are checked against mill certificates, the CMM measures the first article dimension by dimension, 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 results travel with the batch paperwork.
Applications
The metal fitting sits in automotive assemblies and under-hood equipment for OEM and Tier-1 customers.
The same metal fitting is often run in more than one assembly, so a single grade and coating can cover each application, without a second tooling round.
Specifications
| Item | Deep Drawn Fuel Pump Cover with Fittings |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – unusual walls, threads or tolerances are feasibility-checked first; revisions are re-quoted once rather than silently absorbed. |
| Tooling | The die is dedicated to your part and maintained on a recorded schedule. |
| Samples | Prototype and pre-production samples are provided against the drawing, so the sample is retained as the master, and production starts only after your written sign-off. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass and copper – the grade is matched to the duty of this fitting. |
| Surface finish | Plating, powder coating, anodising or polishing, per the print; alternatives quoted with the quotation, samples approved in writing. |
| Processing | Deep drawing from coil or blank, with in-process annealing so walls thin evenly; in-process checks sit between stages, not only at the end. |
| Equipment | Mechanical presses 5-250 T plus 250-500 T hydraulics, with in-line annealing, with in-house toolmaking to keep dies and fixtures maintained. |
| Tolerance | +/-0.05 mm on formed features, with capability data on critical dimensions; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | FOB Ningbo or Shanghai, payment by T/T or L/C, quoted in USD or EUR; repeat orders reuse the approved first article. |
