Custom aluminum turned housings are precision cylindrical enclosures machined from solid 6061-T6 or 6063 aluminum bar stock. They protect and locate sensors, motors, electronics and optical modules while keeping wall thickness, bore alignment and mounting features within tight tolerance.
We machine the outer profile, internal bored cavities, threads and mounting holes on CNC lathes with live-tool milling in a single setup. This protects bore-to-body concentricity and lets us add side flats, cross holes, slots and O-ring grooves without refixturing. Bore depth is held to ±0.005 mm, so mating components seat to the designed depth every time.
Finishing is completed in-house: natural or black anodizing, sandblasting, laser marking and optional powder coating. From 10-piece prototypes to 50,000+ units per year, housings ship deburred, cleaned and inspection-reported for sensor housings, motor end caps, electronic enclosures, instrument casings and optical modules.
Rough and finish boring of internal cavities on live-tool lathes. Multiple diameters and counterbores completed in one chucking for perfect alignment and +/-0.005mm bore tolerance.
Live-tool milling creates wrench flats, cross holes and alignment slots without a second setup. Turn-mill centers reduce handling and improve concentricity on complex housing parts.
Type II/III anodizing, bead blasting and laser marking performed in-house. Every housing receives consistent corrosion protection and appearance finish before inspection.
From aerospace-grade aluminum to medical-certified engineering plastics, our in-house CNC machining centers work a broad range of metals and plastics under one roof.
