This Sheet Metal Fabrication Sheet Metal Deep Drawing Parts Hydroforming is an Aunov Tech production part in stainless steel, quoted and built to customer print. In operation, the deep drawn part replaces a machined-from-solid body with a lighter, faster drawn shell. One production floor covers forming, finishing and inspection, so first-article dimensions hold through volume batches under one roof.
Product overview
The drawing for this metal component fixes, wall thinning, concentricity and the finished mating faces, audited against the approved sample at each production release.
Die building, pressing and machining for this metal component are all in house, so a change of wall or hole does not restart the programme, and the die record stays with your part number.
How it is manufactured
This is how the metal component is built: A tube preform is expanded against the die by internal pressure; the die contour is maintained against the approved first article.
The chassis pan manufacturing record is archived together with the drawing revision that produced it. Mill certificates are filed per heat, so chassis pan traceability survives a change of material batch.
Materials and finishing
Base materials in stock: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and the grade agreed for this metal component is carbon steel or stainless.
Finish selection follows the working environment: polishing, plating in zinc, nickel or chrome, anodising, powder coating, electrophoresis and passivation. Once approved, the finish for this metal component is fixed and does not get re-decided.
The chassis pan manufacturing record is archived together with the drawing revision that produced it. Mill certificates are filed per heat, so chassis pan traceability survives a change of material batch.
Quality control
Quality management is certified to ISO 9001: incoming material is verified against mill certificates, a full CMM report approves the first article, and later batches follow the sampling plan agreed at approval. First-article inspection of the chassis pan runs on the CMM: thread classes gauged, diameters logged. Functional testing – torque, leak or pressure – can be written into the plan, and the inspection report ships with each batch.
Typical applications
You will find this metal component inside industrial machinery and equipment assemblies for OEM and Tier-1 customers.
Drawings for this metal component are adapted across programmes, so one tooling set serves every position, and the drawing stays common.
Customization and options
Frequently varied options
Options customers tend to adapt on this metal component: material grade, wall band, flange shape, thread size and finish for the working environment, and how the order is released – sample, pilot run or scheduled call-off.
Each quote for this metal component states which variations are already tooled, so you can see which options are free and which need new tooling. Nothing on the chassis pan moves until a revision is issued in writing.
Specifications
| Item | Sheet Metal Fabrication Sheet Metal Deep Drawing Parts Hydroforming |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – DFM notes are returned before any tooling is cut; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so a die can be re-cut against the approved drawing, and ownership is confirmed on the quotation. |
| Samples | First-article samples ship with a dimensional report and material certificate, so any deviation is corrected at sample stage, and the signed sample is kept for future reorders. |
| Materials | Materials held include carbon steel, 304 / 316 stainless, aluminium and brass; mill certificates and heat numbers accompany the first article. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; finish thickness and adhesion checked on the first article. |
| Processing | Coil-fed stamping, deburred and finished to the print; in-process checks sit between stages, not only at the end. |
| Equipment | Mechanical presses 5-250 T, in-press forming and piercing, with CNC turning centres for secondary operations and CMM inspection. |
| Tolerance | +/-0.05 mm to +/-0.1 mm across the part; finer bands confirmed from capability data before quoting. |
| Delivery terms | CIF or DDP, with FOB available, payment by T/T or L/C, quoted in USD or EUR; sea or air freight is quoted to your door. |
Packing and shipment
For this metal component, protection starts at the surface: each coating gets its own packing – interleaves, bags or trays, then sealed cartons are palletised for export, with documents and marks to your instruction.
