Aunov Tech supplies the Deep drawn punching parts as a stainless steel component manufactured entirely in house. In service, the deep drawn part carries the formed geometry the assembly needs at volume. One production floor covers forming, finishing and inspection, so repeat orders stay aligned with the approved sample under one roof.
Product overview
What defines this metal component is, draw depth, wall band and the surfaces that forming cannot hold, audited against the approved sample at each production release.
Toolroom, presses and machining centres used on this metal component operate on the same site, so the route from print to sample stays short, with the tooling history retained in house.
How it is manufactured
Production of this metal component is locked to one route: Coil is blanked and drawn through progressive and single-stage dies; threads are single-pointed or rolled and seats bored in one setup where possible.
Repeat punching part orders are measured against the approved sample, so neither material nor finish drifts between lots. The approved punching part sample governs later runs, and any grade change is agreed in writing first.
Materials and finishing
Standard stock includes cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and the grade agreed for this metal component is carbon steel or stainless.
The finish is chosen for the duty it will see: plating, anodising, powder coating, electrophoresis and passivation. The finish on this metal component is locked to the drawing revision, so later orders match.
Every punching part order keeps its trace back to the approved first article, and a reorder is a repeat rather than a new start. The approved punching part sample governs later runs, and any grade change is agreed in writing first.
Quality control
Quality management is certified to ISO 9001: material traceability starts with mill certificates, the first article is CMM-measured against the print, and every production run is inspected against the first-article report. First-article inspection of the punching part runs on the CMM: thread classes gauged, diameters logged. Torque, leak and pressure tests are available where the assembly needs them, and results travel with the batch paperwork.
Applications
Typical installation of the metal component is in industrial equipment and general assembly work for OEM and Tier-1 customers.
One drawing for this metal component is commonly applied to several programmes, so one approved version covers the whole range, and approvals carry across programmes.
Specifications
| Item | Deep drawn punching parts |
|---|---|
| Brand | AUNOV |
| Designing | The quotation follows your print, not a catalogue – unusual walls, threads or tolerances are checked for feasibility first. |
| Tooling | Progressive and drawing dies are designed and built in house, so no tooling step is outsourced, and first-article timing is measured from the tooling start date. |
| Samples | Sample lead time is quoted with the order, and the approved sample governs the run. |
| Materials | Standard stock: carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass; grade and temper are confirmed in writing before tooling. |
| Surface finish | Natural, plated or coated – the print decides, and the agreed finish is logged; masking and laser marking available where needed. |
| 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 | Mechanical presses 5-250 T plus 250-500 T hydraulics, with in-line annealing; secondary ops run on CNC turning centres, inspection on the CMM. |
| Tolerance | +/-0.1 mm general on drawn sections, +/-0.03 mm on machined seats; finer bands confirmed from capability data before quoting. |
| Delivery terms | FOB, CIF or DDP per Incoterms – payment by T/T or L/C, with shipping quoted door-to-door. |
