Finned Aluminium Rotor Housing — 38 Fins, 0.9 mm Walls
A finned rotor housing with 38 turned fins and six internal ribs, machined from 6061-T6 billet with 0.9 mm fin walls held to ±0.05 mm across the full 160 mm diameter.
From one-off prototypes to 100,000-piece production runs. Upload a STEP or DWG file and our engineering team returns a manufacturability review and quotation within 24 hours.


















3-, 4- and 5-axis milling for prismatic and free-form parts

20 ± 1 °C — Inspection & metrology
Calibrated machines, temperature-controlled inspection and documented processes — so the ten-thousandth part measures like the first.
Send 3D geometry (STEP, IGES, X_T, STL) and, where applicable, a 2D drawing with GD&T. Quantity, material and finish help us quote accurately.
A process engineer reviews manufacturability and returns a firm price with lead time — typically within 24 hours on working days.
After PO confirmation we release the job, run first-article inspection and monitor critical dimensions throughout the run.
Parts ship with a dimensional report and material certificate, by air or sea, with tracking from our floor to your dock.
