This Cooling pump electric motor casing is an Aunov Tech production part in brass or stainless steel, quoted and built to customer print. On the product, the CNC machined part provides the finished surfaces, threads and seats the mating parts locate on. Die work, machining and CMM inspection are all in-house, so first-article dimensions hold through volume batches without a second supplier involved.
Product overview
What matters most on this metal casing is, wall thinning, concentricity and the finished mating faces, checked by CMM at first article and by gauge in production.
Tooling and finishing for this metal casing run under one roof, which keeps the sample loop inside our own schedule, and the die record stays with your part number.
How it is manufactured
This is how the metal casing is built: Coil is blanked and drawn through progressive and single-stage dies; secondary machining holds the seats, threads and faces that forming cannot produce.
Production batches of the cooling pump electric are gauged back to the signed first article, not to a memory of it. Mill certificates are filed per heat, so cooling pump electric traceability survives a change of material batch.
Materials and finishing
The standard stock list carries carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper and the grade agreed for this metal casing is carbon steel or stainless.
Because the part faces weather and wash cycles, the coating is chosen for durability: zinc and nickel plating, chrome, anodising, powder coating and passivation. The agreed finish for this metal casing travels with the part number on every reorder.
The cooling pump electric manufacturing record is archived together with the drawing revision that produced it. Any change to the cooling pump electric drawing is re-approved and re-verified before production continues.
Quality control
Quality management is certified to ISO 9001: incoming material is verified against mill certificates, first-article geometry is confirmed on the CMM, and production batches are inspected on a sampling plan. CMM first-article measurement of the cooling pump electric covers diameters and gauges thread class. Tests for torque, leakage or pressure can be arranged when the service demands them, with certificates included in the shipment file.
Typical applications
The metal casing is specified into pumps, valves and hydraulic equipment across automotive, appliance and industrial programmes.
A single design of this metal casing is often reused across a product family, so the specification is set by the toughest of them, and the drawing stays common.
Specifications
| Item | Cooling pump electric motor casing |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – DFM notes are returned before any tooling is cut; changes are priced before they are made. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so tooling lead time stays under our control, and first-article timing is measured from the tooling start date. |
| Samples | Pre-production samples come with a full inspection report, so any deviation is corrected at sample stage, and later batches are gauged back to the signed sample. |
| Materials | Materials held include carbon steel, 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; the agreed finish travels with the part number. |
| Processing | Multi-stage deep drawing with interstage annealing, trimmed and pierced in following dies; in-process checks sit between stages, not only at the end. |
| Equipment | Press shop running 5-250 T mechanical and 250-500 T hydraulic presses, annealing ovens on site, with CNC turning centres for secondary operations and CMM inspection. |
| Tolerance | +/-0.05 mm on formed features, with capability data on critical dimensions; critical dimensions carry CMM data with the shipment. |
| Delivery terms | CIF or DDP, with FOB available, payment by T/T or L/C, quoted in USD or EUR; repeat orders reuse the approved first article. |
