This Cooling pump electric motor housing is an Aunov Tech production part in stainless steel, quoted and built to customer print. Once installed, the drawn housing encloses the sensitive internals and carries the mounting interface. One production floor covers forming, finishing and inspection, so the approved sample defines every later batch without re-quoting the job elsewhere.
Product overview
This metal housing is defined by, wall thickness control, flange geometry and the sealing surface, controlled from the approved first article onward.
Tooling and finishing for this metal housing run under one roof, so a drawing change is absorbed in one step, and nothing about the route depends on a third party.
How it is manufactured
This is how the metal housing is built: 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.
The tooling record is stored against the part number, and a reorder is a repeat, not a new start.
Materials and surface finish
Our stock list runs to cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and this metal housing runs in carbon steel or stainless.
Coating selection follows the duty – indoor, outdoor or under-hood: polishing, zinc / nickel / chrome plating, anodising or powder coating. It is fixed on the drawing for this metal housing, so repeat orders never reopen the question.
Every batch is checked against the approved sample, and material certificates are kept per batch.
Quality control and inspection
Production runs under an ISO 9001 certified quality system: certificates verify each incoming batch of material, a full CMM report approves the first article, and every production run is inspected against the first-article report. At drawn housing level, cavity depth and seal-face finish are measured at first article, and leak testing is available for sealed duty. Where the application asks for it, torque, leak or pressure testing is added to the plan, and the inspection report ships with each batch.
Where the part is used
The metal housing sits in fluid power and pump assemblies in volume programmes as well as aftermarket supply.
One drawing for this metal housing is commonly applied to several programmes, so one tooling set serves every position, and cost per piece stays at the volume tier.
Specifications
| Item | Cooling pump electric motor housing |
|---|---|
| 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 | Progressive and drawing dies are designed and built in house, so tooling lead time stays under our control, and ownership is confirmed on the quotation. |
| Samples | Samples are issued for approval before the run, so the sample is retained as the master, and the signed sample is kept for future reorders. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass and copper – the grade is matched to the duty of this housing. |
| Surface finish | Phosphating for coating adhesion, then powder coating, e-coating or zinc plating; chrome and nickel for visible faces. |
| Processing | Coil blanking, progressive drawing through 3-5 stages with anneals between, trim and pierce, then deburr and finish. |
| Equipment | Mechanical presses from 5 to 250 T, hydraulic presses 250-500 T, annealing ovens, plus CNC turning and machining centres. |
| Tolerance | +/-0.1 mm to +/-0.2 mm general; critical features held to the drawing and verified on the first article. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, T/T or L/C, with D/P accepted on repeat business; price breaks tie to annual volume. |
