Aunov Tech supplies the Custom Deep Drawn Part Stainless Steel 316 Grade OD 4mm One End Closed as a stainless steel component manufactured entirely in house. In operation, the deep drawn part replaces a machined-from-solid body with a lighter, faster drawn shell. Forming, machining and inspection share one floor, so the approved sample defines every later batch without re-quoting the job elsewhere.
Product overview
The specification of this stainless steel component turns on, draw depth, wall band and the surfaces that forming cannot hold, recorded on the inspection report for every batch.
Tooling and finishing for this stainless steel component run under one roof, so the route from print to sample stays short, and the same die can be re-cut from the original data.
How it is manufactured
Production follows a defined route: Drawing runs from flat blank to finished envelope in one controlled sequence; piercing and trimming are done in the same die line.
The stepped closed-end tubes, tooling and setup record is stored against the part number, so nothing depends on someone remembering. The approved stepped closed-end tubes, sample governs later runs, and any grade change is agreed in writing first.
Materials and finishing
The standard stock list carries cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and the grade agreed for this stainless steel component is 304 / 316 stainless steel.
Coating and polishing are matched to the end use: polishing, plating in zinc, nickel or chrome, anodising, powder coating, electrophoresis and passivation. The finish on this stainless steel component is locked to the drawing revision, so later orders match.
Production batches are gauged to the signed first article, and material certificates are kept per batch.
Quality control
Quality management is certified to ISO 9001: incoming material is verified against mill certificates, the CMM measures the first article dimension by dimension, and later batches follow the sampling plan agreed at approval. The stepped closed-end tubes, first article is measured on the CMM and thread gauges confirm class. 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
Typical installation of the stainless steel component is in industrial equipment and general assembly work for customers who own the drawing and the tooling.
A single design of this stainless steel component is often reused across a product family, so the tightest tolerance in the family sets the spec, and no re-tooling is needed.
Options and variations
Where designs usually differ
Design freedom covers material (carbon steel, stainless, aluminum, brass), the finish for the environment, wall bands, flange forms, threads and bosses, closed ends and finishes matched to the working environment, and lot sizing from prototypes to call-off.
Changes are quoted with their tooling impact stated explicitly: free variations stay free, and anything needing a die or fixture is priced separately.
Specifications
| Item | Custom Deep Drawn Part Stainless Steel 316 Grade OD 4mm One End Closed |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – unusual walls, threads or tolerances are feasibility-checked first; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Progressive and drawing dies are designed and built in house, so no tooling step is outsourced, and maintenance is tracked against the part number. |
| Samples | First-article samples ship with a dimensional report and material certificate, so the part is proven before it is made in volume, and mass production is gated on that approval. |
| Materials | Materials held include carbon steel, 304 / 316 stainless, aluminium and brass; the final grade is fixed with the drawing review. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; finish thickness and adhesion checked on the first article. |
| Processing | Tube drawing with precision turning on critical diameters; first articles verify the whole flow before the run is released. |
| Equipment | Drawn-tube benches, in-line annealing and CNC turning, with in-house toolmaking to keep dies and fixtures maintained. |
| Tolerance | +/-0.03 mm on machined features, +/-0.1 mm on formed ones; critical dimensions carry CMM data with the shipment. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, T/T with deposit and L/C for larger runs; call-off schedules are supported. |
Packaging and delivery
Packing for this stainless steel component is chosen around the coating: interleaving, bagging or tray packing is matched to the surface, in sealed cartons on export pallets; shipping documents and carton marks follow your instructions.
