Aunov Tech manufactures the Precision sheet metal deep draw stainless steel battery can in stainless steel on a single production floor. In operation, the deep drawn part combines forming and machining to reach the print on every controlled face. Drawing, cutting and measurement sit on one floor, so repeat orders stay aligned with the approved sample without handing the part to another vendor.
Product overview
The specification of this stainless steel can turns on, draw depth, wall band and the surfaces that forming cannot hold, recorded on the inspection report for every batch.
Toolroom, presses and machining centres used on this stainless steel can operate on the same site, which keeps revision loops short and samples fast, and every step is logged against the part number.
Production route
Manufacturing runs on a controlled process path: Drawing converts a flat blank into the finished envelope in one controlled sequence; the finishing operations hold the concentricity the drawing calls for.
The tooling record is stored against the part number, so a repeat order starts from the same approved data.
Materials and surface finish
Everything is drawn from a fixed stock list: carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and the grade agreed for this stainless steel can is 304 / 316 stainless steel.
With the working face exposed, the finish is selected for cleanliness: zinc and nickel plating, chrome, anodising, powder coating and passivation. It is fixed on the drawing for this stainless steel can, so repeat orders never reopen the question.
Production is compared with the approved sample every run, and material certificates are kept per batch.
Quality control
Production runs under an ISO 9001 certified quality system: mill certificates cover every delivery of stock, the CMM measures the first article dimension by dimension, and later batches follow the sampling plan agreed at approval. CMM first-article measurement of the sheet metal deep covers diameters and gauges thread class. Where the application asks for it, torque, leak or pressure testing is added to the plan, with certificates included in the shipment file.
Applications
This stainless steel can normally works inside electronic and power conversion equipment for customers who buy to drawing.
This stainless steel can is supplied to several positions in the same machine, so the finish is chosen to cover the harshest of them, and cost per piece stays at the volume tier.
Specifications
| Item | Precision sheet metal deep draw stainless steel battery can |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – samples are reverse-measured into a controlled drawing; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Progressive and forming dies are designed, built and maintained on site. |
| Samples | First-article samples ship with a dimensional report and material certificate, so the part is proven before it is made in volume, and the signed sample is kept for future reorders. |
| Materials | Standard stock: carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass; material substitutes are proposed only with your written approval. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; 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; 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, with in-house toolmaking to keep dies and fixtures maintained. |
| Tolerance | +/-0.05 mm on formed features, with capability data on critical dimensions; capability is checked on the first article before the run continues. |
| Delivery terms | CIF or DDP, with FOB available, T/T with deposit and L/C for larger runs; each volume tier carries its own quoted price. |
