Aunov Tech supplies the Custom Heat shields for Automotive Parts Double Layer Deep Drawn Parts as a stainless steel component manufactured entirely in house. In the assembly, the drawn housing shields the assembly from dust, moisture and handling while locating it in place. The same floor forms, machines and inspects the part, which keeps tolerances consistent from sample to volume under one roof.
Product overview
This metal component is defined by, draw depth, wall band and the surfaces that forming cannot hold, controlled from the approved first article onward.
Die building, pressing and machining for this metal component are all in house, so revisions do not wait on outside suppliers, and nothing about the route depends on a third party.
How it is manufactured
This is how the metal component is built: Coil is blanked and drawn through progressive and single-stage dies; wall thickness is checked at the thinnest section after forming.
Repeat terminal clip contact orders are measured against the approved sample, so neither material nor finish drifts between lots. The approved terminal clip contact sample governs later runs, and any grade change is agreed in writing first.
Materials and finishing
Everything is drawn from a fixed stock list: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze with this metal component costed in carbon steel or stainless.
Coating selection follows the duty – indoor, outdoor or under-hood: zinc, nickel or chrome plating, anodising, powder coating, electrophoresis and passivation. Once approved, the finish for this metal component is fixed and does not get re-decided.
Each shipment is verified against the master sample, so the colour and grain of the finish stay stable.
Quality control
The factory operates with ISO 9001 certification: 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. First article of the terminal clip contact includes cavity depth and seal face finish data. Functional testing – torque, leak or pressure – can be written into the plan, and the inspection report ships with each batch.
Applications
The metal component is specified into automotive sub-assemblies and adjacent equipment in volume programmes as well as aftermarket supply.
The same metal component is used across several platforms, so the tightest tolerance in the family sets the spec, and no re-tooling is needed.
Customization and options
The options customers tune most
What customers usually vary on this metal component: coating, wall bands, flange profiles, threads and the degree of closure on the ends, and whether the programme starts as a sample or a full release.
The quotation for this metal component marks what the existing tooling can do, so you can see which options are free and which need new tooling. An approved revision of the terminal clip contact drawing replaces the previous master.
Specifications
| Item | Custom Heat shields for Automotive Parts Double Layer Deep Drawn Parts |
|---|---|
| Brand | AUNOV |
| Designing | The drawing is reviewed first; the agreed version then governs every batch. |
| Tooling | Tooling is designed and built in house and held under your part number, so the die stays dedicated to your part. |
| Samples | Sample parts are measured and reported before submission, so the approved first article becomes the gauge reference, and production starts only after your written sign-off. |
| Materials | Materials held include carbon steel, 304 / 316 stainless, aluminium and brass; material substitutes are proposed only with your written approval. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; masking and laser marking available where needed. |
| Processing | Deep drawing on maintained presses, blank size and lubrication logged per run; first articles verify the whole flow before the run is released. |
| Equipment | Mechanical presses from 5 to 250 T and hydraulic presses 250-500 T, with in-line annealing furnaces; first articles and batch samples are checked on the CMM. |
| Tolerance | +/-0.03 mm on turned secondary features, +/-0.1 mm on as-drawn walls; finer bands confirmed from capability data before quoting. |
| Delivery terms | FOB Ningbo or Shanghai, T/T with deposit and L/C for larger runs; sea or air freight is quoted to your door. |
Packaging and delivery
The finish on this metal component dictates how it is packed: interleaving, individual bags or trays are chosen by finish type, in sealed export cartons, palletised and marked as you direct.
