This Hydroformed Stainless Steel Cover is an Aunov Tech production part in stainless steel, quoted and built to customer print. Once installed, the drawn housing provides a closed, seam-free body the customer builds into. Forming and machining share equipment, staff and batch records, so first-article dimensions hold through volume batches without handing the part to another vendor.
Product overview
The drawing for this stainless steel cover fixes, the formed envelope, flatness and hole location, checked by CMM at first article and by gauge in production.
Die work and machining for this stainless steel cover sit on the same floor, so feasibility questions are answered on the shop floor, and the die record stays with your part number.
How it is manufactured
Manufacturing runs on a controlled process path: A tube preform is expanded against the die by internal pressure; wall thickness is checked around the expanded contour after forming.
Each shipment is traceable to the signed first article, and that record is what every reorder is built from.
Materials and finishing
Standard stock includes carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this stainless steel cover is costed in 304 / 316 stainless steel.
The surface treatment is picked to match the service conditions: plating, anodising, powder coating, electrophoresis and passivation. It is fixed on the drawing for this stainless steel cover, so repeat orders never reopen the question.
The rectangular cover tooling and setup record is stored against the part number, so nothing depends on someone remembering. First article, drawing revision and material cert travel with each rectangular cover batch.
Quality control
Production runs under an ISO 9001 certified quality system: certificates verify each incoming batch of material, the CMM measures the first article dimension by dimension, and later batches follow the sampling plan agreed at approval. Cavity depth and seal face finish on the rectangular cover are verified at first article. Where the application asks for it, torque, leak or pressure testing is added to the plan, and the batch file carries the results.
Applications
You will find this stainless steel cover inside industrial equipment and general assembly work across automotive, appliance and industrial programmes.
The same stainless steel cover is used across several platforms, so the finish is chosen to cover the harshest of them, and the die does not have to change.
Customization and options
The options customers tune most
The parts of the print for this stainless steel cover that get adjusted: material grade, wall band, flange shape, thread size and finish for the working environment, and the batch pattern – prototype, pilot lot or scheduled production.
Tooled and untooled options for this stainless steel cover are listed separately, so new tooling is only quoted where it is genuinely required. The quotation for the rectangular cover states both quantities and price breaks.
Specifications
| Item | Hydroformed Stainless Steel Cover |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – unusual walls, threads or tolerances are feasibility-checked first; the agreed version governs every later batch. |
| Tooling | Tooling is quoted once and held – reorders are priced on the part, not on the die. |
| Samples | The sample you approve becomes the gauge reference for production. |
| Materials | Stock covers carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass; mill certificates and heat numbers accompany the first article. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; masking and laser marking available where needed. |
| Processing | Tube or sheet preform, hydroforming into the finished contour, trimming, then annealing and finishing. |
| Equipment | Press shop running 5-250 T mechanical and 250-500 T hydraulic presses, annealing ovens on site; first articles and batch samples are checked on the CMM. |
| Tolerance | +/-0.05 mm on flange and rim dimensions, wall controlled by the draw; capability is checked on the first article before the run continues. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, T/T or L/C, with D/P accepted on repeat business; sea or air freight is quoted to your door. |
Packaging and delivery
For this stainless steel cover, protection starts at the surface: interleaving, bagging or tray packing is matched to the surface, in sealed cartons on export pallets; shipping documents and carton marks follow your instructions.
