Aunov Tech manufactures the Deep Drawn Oilpan in stainless steel on a single production floor. In the assembly, the deep drawn part replaces a machined-from-solid body with a lighter, faster drawn shell. Drawing, cutting and measurement sit on one floor, so the approved sample defines every later batch without re-quoting the job elsewhere.
Product overview
For this metal component, the drawing centres on, wall thickness control, flange geometry and the sealing surface, re-checked whenever the drawing is revised.
The whole route from die to finished metal component stays in house, so a drawing change is absorbed in one step, with process data archived for repeat orders.
How it is manufactured
The route for this metal component is fixed and repeatable: The drawn envelope is produced in stages with anneals between them; piercing and trimming are done in the same die line.
Process settings are archived with the part number, so nothing depends on the operator remembering.
Materials and finishing
Our stock list runs to cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze with carbon steel or stainless specified on the drawing for this metal component.
Finish selection follows the working environment: zinc and nickel plating, chrome, anodising, powder coating and passivation. It is written into the drawing for this metal component, so it cannot drift between batches.
The shallow rectangular pan manufacturing record is archived together with the drawing revision that produced it. Deviations on the shallow rectangular pan are reported before shipment rather than found on your assembly line.
Quality control
An ISO 9001 certified system governs production: certificates verify each incoming batch of material, the CMM measures the first article dimension by dimension, and routine sampling keeps batches aligned with the first article. The shallow rectangular pan first article is measured on the CMM and thread gauges confirm class. Tests for torque, leakage or pressure can be arranged when the service demands them, and the batch file carries the results.
Applications
The metal component is specified into industrial machinery and equipment assemblies for customers who own the drawing and the tooling.
The same metal component is often run in more than one assembly, so wall bands and finishes are selected to cover the widest duty, and no re-tooling is needed.
Options and variations
Frequently varied options
Commonly varied points: material and finish for the environment, wall bands, flange forms, threads and bosses, closed ends and finishes matched to the working environment, and batch size from first prototypes to call-off schedules.
Each variation is priced with its tooling effect made visible, so you can see which options are free and which need new tooling.
Specifications
| Item | Deep Drawn Oilpan |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – samples are reverse-measured into a controlled drawing; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Tooling is built and held under your part number, so a die can be re-cut against the approved drawing, and first-article timing is measured from the tooling start date. |
| Samples | Samples are issued for approval before the run, and production starts only after written sign-off. |
| Materials | Stock runs to carbon steel, 304 / 316 stainless, aluminium and brass; mill certificates and heat numbers accompany the first article. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; the finish is inspected with the dimensional report on the first article. |
| 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 | 5-250 T mechanical presses, 250-500 T hydraulic presses and annealing furnaces in line, backed by CNC turning centres and a climate-controlled inspection room. |
| 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. |
Packaging and delivery
Packaging protects the finished surfaces of this metal component: interleaving, individual bags or trays are chosen by finish type, then cartons are sealed and palletised, with marks and documents as you specify.
