Produced in aluminum by Aunov Tech, the Deep Drawn Aluminum Battery Housing is formed and machined on the same floor. On the product, the drawn housing encloses the sensitive internals and carries the mounting interface. Forming, machining and inspection share one floor, which keeps tolerances consistent from sample to volume without re-quoting the job elsewhere.
Product overview
The drawing for this aluminium housing fixes, material grade, wall uniformity and thread position, controlled from the approved first article onward.
The whole route from die to finished aluminium housing stays in house, so the route from print to sample stays short, with process data archived for repeat orders.
From coil to finished part
The process for this aluminium housing runs in a fixed sequence: The shell starts as coil or blank and is drawn through single and progressive dies; the finishing operations hold the concentricity the drawing calls for.
The -plated case tooling and setup record is stored against the part number, so nothing depends on someone remembering. Process settings for the -plated case are archived, so later runs can be compared with the one you approved.
Materials and finishing
Materials kept on the floor cover cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and this aluminium housing runs in aluminium.
Because the part works in contact with media, the coating is chosen for cleanliness: plating, anodising, powder coating, electrophoresis and passivation. Once approved, the finish for this aluminium housing is fixed and does not get re-decided.
The -plated case manufacturing record is archived together with the drawing revision that produced it. Process settings for the -plated case are archived, so later runs can be compared with the one you approved.
Quality control
The factory operates with ISO 9001 certification: mill certificates cover every delivery of stock, first articles are measured on a CMM, and later batches follow the sampling plan agreed at approval. Cavity depth and seal face finish of the -plated case are measured 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 aluminium housing inside electronic enclosures and power equipment across automotive, appliance and industrial programmes.
This aluminium housing is supplied to several positions in the same machine, so wall bands and finishes are selected to cover the widest duty, and approvals carry across programmes.
Options and variations
Where designs usually differ
Customer choices typically cover material (carbon steel, stainless, aluminum, brass), surface treatment, draw depths, flange and thread features, vent holes, sealed exits and finishes matched to the environment, and order shape – prototype lots first, scheduled volumes after approval.
Quotes show which options the current die already supports, making the cost of each choice clear before you commit.
Specifications
| Item | Deep Drawn Aluminum Battery Housing |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – unusual walls, threads or tolerances are feasibility-checked first; changes are priced before they are made. |
| Tooling | Tooling is built and held under your part number, so a die can be re-cut against the approved drawing, and maintenance is tracked against the part number. |
| Samples | Approval is in writing, and the signed sample is kept as the reference for repeats. |
| Materials | Stock runs to carbon steel, 304 / 316 stainless, aluminium and brass; mill certificates and heat numbers accompany the first article. |
| Surface finish | Surface treatment matched to the duty: plating, coating or polishing; 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; every stage is logged against your part number. |
| 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 | +/-0.05 mm to +/-0.1 mm across the part, wall thickness held to print; dimensional reports accompany the first article. |
| Delivery terms | CIF or DDP, with FOB available, T/T with deposit and L/C for larger runs; price breaks tie to annual volume. |
Packing and shipment
Finish comes first when packing this aluminium housing: interleaves, bags or trays are matched to the surface treatment, in sealed cartons on export pallets, documented and marked to your instruction.
