Aunov Tech supplies the Deep Drawn Military Case with Cover as a stainless steel component manufactured entirely in house. In operation, the drawn housing shields the assembly from dust, moisture and handling while locating it in place. Forming and machining share equipment, staff and batch records, so repeat orders stay aligned with the approved sample on one production route.
Product overview
For this metal cover, the drawing centres on, wall thickness control, flange geometry and the sealing surface, audited against the approved sample at each production release.
The press shop and machine shop that make this metal cover share one floor, which keeps the sample loop inside our own schedule, and nothing about the route depends on a third party.
How it is manufactured
Production follows a defined route: The drawn envelope is produced in stages with anneals between them; flanges and rims are formed in the same line, then trimmed to length.
The -plated military case tooling and setup record is stored against the part number, so nothing depends on someone remembering. Mill certificates are filed per heat, so -plated military case 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 this metal cover runs in carbon steel or stainless.
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 cover, so it cannot drift between batches.
Paperwork matches the parts: material certs and dimensional reports on request.
Quality control and inspection
Quality management is certified to ISO 9001: stock arrivals are checked against mill certificates, the CMM measures the first article dimension by dimension, and every production run is inspected against the first-article report. The -plated military case first-article report carries cavity depth and seal face finish. Tests for torque, leakage or pressure can be arranged when the service demands them, and the batch file carries the results.
Applications
You will find this metal cover inside industrial machinery and equipment assemblies in volume programmes as well as aftermarket supply.
One part number for this metal cover frequently serves several assemblies, so the tightest tolerance in the family sets the spec, and approvals carry across programmes.
Customization and options
Where designs usually differ
Typical decisions customers make on this metal cover: grade and finish for the environment, wall thickness bands, flange and rim forms, threads, bosses and closed ends, and how the order is released – sample, pilot run or scheduled call-off.
Each quote for this metal cover states which variations are already tooled, so the cost of a change is visible before you commit. Changes to the -plated military case are made only under a written revision.
Specifications
| Item | Deep Drawn Military Case with Cover |
|---|---|
| Brand | AUNOV |
| Designing | Your drawing sets the part – unusual walls, threads or tolerances are feasibility-checked first; changes are priced before they are made. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so no tooling step is outsourced, and the charge is refundable against agreed volumes. |
| Samples | Pre-production samples come with a full inspection report, so the part is proven before it is made in volume, and later batches are gauged back to the signed sample. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass and copper – the grade is matched to the duty of this cover. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; the finish is inspected with the dimensional report on the first article. |
| Processing | Multi-stage deep drawing with interstage annealing, trimmed and pierced in following dies; batch records are filed so a repeat order starts from approved data. |
| 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 | +/-0.1 mm general on drawn sections, +/-0.03 mm on machined seats; finer bands confirmed from capability data before quoting. |
| Delivery terms | FOB Ningbo or Shanghai, T/T with deposit and L/C for larger runs; price breaks tie to annual volume. |
Packaging and delivery
This metal cover is packed to protect the finish: the coating decides whether parts are interleaved, bagged or tray-packed, in sealed cartons on export pallets, with documents issued to your instructions.
