Aunov Tech builds this Deep Drawn Square Cover – Custom Tooling in stainless steel, from coil or bar through to the finished surfaces. In duty, the drawn housing provides a closed, seam-free body the customer builds into. Die work, machining and CMM inspection are all in-house, and a design change is re-sampled in one place without re-quoting the job elsewhere.
Product overview
For this metal cover, the drawing centres on, the formed envelope, flatness and hole location, re-checked whenever the drawing is revised.
Die building, pressing and machining for this metal cover are all in house, so feasibility questions are answered on the shop floor, and every step is logged against the part number.
How it is manufactured
Manufacturing runs on a controlled process path: 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.
Each shipment is traceable to the signed first article, so a repeat order starts from the same approved data.
Materials and finishing
Working stock covers carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this metal cover runs in carbon steel or stainless.
Coating and polishing are matched to the end use: polishing, zinc / nickel / chrome plating, anodising or powder coating. The agreed finish for this metal cover travels with the part number on every reorder.
Repeat square cover – orders are measured against the approved sample, so neither material nor finish drifts between lots. The signed square cover – sample remains the reference and is kept with the job file.
Quality control
Production runs under an ISO 9001 certified quality system: incoming material is verified against mill certificates, the CMM measures the first article dimension by dimension, and every production run is inspected against the first-article report. The square cover – first-article report carries cavity depth and seal face finish. Functional testing – torque, leak or pressure – can be written into the plan, and results travel with the batch paperwork.
Applications
The metal cover is fitted into industrial machinery and equipment assemblies under schedules that run for years at a time.
A single design of this metal cover is often reused across a product family, so one tooling set serves every position, and no re-tooling is needed.
Specifications
| Item | Deep Drawn Square Cover – Custom Tooling |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings – non-standard features are feasibility-checked at quotation stage. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so die cost stays transparent, and first-article timing is measured from the tooling start date. |
| 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 | Stock covers carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass; material substitutes are proposed only with your written approval. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; finish thickness and adhesion checked on the first article. |
| Processing | Coil blanking and progressive drawing, coining on the final station where the print calls for it; first articles verify the whole flow before the run is released. |
| Equipment | Mechanical presses from 5 to 250 T and hydraulic presses 250-500 T, with in-line annealing furnaces, with in-house toolmaking to keep dies and fixtures maintained. |
| Tolerance | +/-0.05 mm to +/-0.1 mm across the part, wall thickness held to print; finer bands confirmed from capability data before quoting. |
| Delivery terms | CIF or DDP, with FOB available, T/T with deposit and L/C for larger runs; sea or air freight is quoted to your door. |
Also known as: deep drawn stamping parts for square covers — same part, same tooling, only the drawing reference differs.
