This Deep drawing electric motor end cover is an Aunov Tech production part in stainless steel, quoted and built to customer print. On the product, the drawn housing shields the assembly from dust, moisture and handling while locating it in place. Drawing, cutting and measurement sit on one floor, keeping first-article quality through scheduled runs under one roof.
Product overview
What matters most on this metal cover is, wall thickness control, flange geometry and the sealing surface, each measured at first article and gauged on production batches.
Die building, pressing and machining for this metal cover are all in house, which keeps the sample loop inside our own schedule, and the approved sample is kept as the master.
From coil to finished part
Manufacturing runs on a controlled process path: Drawing converts a flat blank into the finished envelope in one controlled sequence; flanges and rims are formed in the same line, then trimmed to length.
Every deep drawing electric order keeps its trace back to the approved first article, and a reorder is a repeat rather than a new start. The approved deep drawing electric sample governs later runs, and any grade change is agreed in writing first.
Materials and finishing
The standard stock list carries carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and this metal cover runs in carbon steel or stainless.
The surface treatment is picked to match the service conditions: zinc and nickel plating, chrome, anodising, powder coating and passivation. Once approved, the finish for this metal cover is fixed and does not get re-decided.
Paperwork matches the parts: material certs and dimensional reports on request.
Quality control
An ISO 9001 certified system governs production: certificates verify each incoming batch of material, a full CMM report approves the first article, and later batches follow the sampling plan agreed at approval. Cavity depth and seal face finish on the deep drawing electric are verified at first article. Torque, leak and pressure tests are available where the assembly needs them, and the inspection report ships with each batch.
Applications
You will find this metal cover inside industrial equipment and general assembly work for customers who own the drawing and the tooling.
A single design of this metal cover is often reused across a product family, so one tooling set serves every position, and the drawing stays common.
Specifications
| Item | Deep drawing electric motor end cover |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – unusual walls, threads or tolerances are feasibility-checked first; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Progressive and forming dies are designed, built and maintained on site. |
| Samples | Samples are issued for approval before the run, so any deviation is corrected at sample stage, and later batches are gauged back to the signed sample. |
| Materials | Carbon steel, 304 / 316 stainless, aluminium and brass are all held in stock; the final grade is fixed with the drawing review. |
| Surface finish | Surface treatment matched to the duty: plating, coating or polishing; masking and laser marking available where needed. |
| 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, with in-house toolmaking to keep dies and fixtures maintained. |
| Tolerance | +/-0.03 mm on turned secondary features, +/-0.1 mm on as-drawn walls; capability is checked on the first article before the run continues. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, payment by T/T or L/C, quoted in USD or EUR; call-off schedules are supported. |
