Aunov Tech builds this Sheet Metal Automotive Parts Deep Drawing Stamping Various Deep Drawn in stainless steel, from coil or bar through to the finished surfaces. In operation, the deep drawn part combines forming and machining to reach the print on every controlled face. The same floor forms, machines and inspects the part, so the approved sample defines every later batch without handing the part to another vendor.
Product overview
The critical features of this metal component are, the formed envelope, flatness and hole location, recorded on the inspection report for every batch.
Forming, machining and finishing for this metal component happen on one site, which keeps revision loops short and samples fast, and the die record stays with your part number.
Production route
This is how the metal component is built: Drawing runs from flat blank to finished envelope in one controlled sequence; threads are single-pointed or rolled and seats bored in one setup where possible.
Route cards follow each automotive seals, grommet batch through the shop, so the next run starts from the data that already worked. Mill certificates are filed per heat, so automotive seals, grommet traceability survives a change of material batch.
Materials and finishing
Standard stock includes cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze with this metal component costed in carbon steel or stainless.
Because the part faces weather and wash cycles, the coating is chosen for durability: zinc and nickel plating, chrome, anodising, powder coating and passivation. It is fixed on the drawing for this metal component, so repeat orders never reopen the question.
Production batches of the automotive seals, grommet are gauged back to the signed first article, not to a memory of it. Any change to the automotive seals, grommet drawing is re-approved and re-verified before production continues.
Quality control
An ISO 9001 certified system governs production: incoming material is verified against mill certificates, the first article is CMM-measured against the print, and production batches are inspected on a sampling plan. First articles of the automotive seals, grommet are CMM measured, with threads gauged to class and diameters recorded. 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.
Where the part is used
This metal component is used in automotive sub-assemblies and adjacent equipment in volume programmes as well as aftermarket supply.
One drawing for this metal component is commonly applied to several programmes, so wall bands and finishes are selected to cover the widest duty, and the drawing stays common.
Customization and options
What customers usually vary
Options customers tend to adapt on this metal component: coating, wall bands, flange profiles, threads and the degree of closure on the ends, with orders run as prototypes, pilot lots or scheduled call-offs.
The quote for this metal component separates tooled options from new work, so the cost of a change is visible before you commit. The automotive seals, grommet only changes against a written revision.
Specifications
| Item | Sheet Metal Automotive Parts Deep Drawing Stamping Various Deep Drawn |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – unusual walls, threads or tolerances are feasibility-checked first; changes are priced before they are made. |
| Tooling | Die design and toolmaking stay in house, so no tooling step is outsourced, and first-article timing is measured from the tooling start date. |
| Samples | Samples are issued for approval before the run, so any deviation is corrected at sample stage, and later batches are gauged back to the signed sample. |
| Materials | Stock runs to carbon steel, 304 / 316 stainless, aluminium and brass; material substitutes are proposed only with your written approval. |
| Surface finish | Natural, plated or coated – the print decides, and the agreed finish is logged; the finish is inspected with the dimensional report on the first article. |
| Processing | Coil blanking and progressive drawing, coining on the final station where the print calls for it; every stage is logged against your part number. |
| Equipment | 5-250 T mechanical presses, 250-500 T hydraulic presses and annealing furnaces in line, with CNC turning centres for secondary operations and CMM inspection. |
| Tolerance | +/-0.05 mm on flange and rim dimensions, wall controlled by the draw; capability is checked on the first article before the run continues. |
| Delivery terms | FOB Ningbo or Shanghai, payment by T/T or L/C, quoted in USD or EUR; sea or air freight is quoted to your door. |
Packing and shipment
Finish comes first when packing this metal component: each coating gets its own packing – interleaves, bags or trays, in sealed cartons on export pallets; shipping documents and carton marks follow your instructions.
