Aluminum spinning services provide a lightweight, highly efficient, and cost-effective cold-forming solution for producing seamless, rotationally symmetrical components. Aluminum's exceptional ductility, high strength-to-weight ratio, and corrosion resistance make spun aluminum parts essential across aerospace, HVAC, automotive, commercial lighting, medical equipment, and architectural sectors. By combining manual craftsmanship for rapid prototyping with multi-axis automated CNC metal spinning lathes for high-volume production, our OEM aluminum spinning services deliver tight dimensional tolerances, smooth surface finishes, and structural repeatability across custom engineering projects.
Selecting the appropriate aluminum alloy and temper is critical to maximizing formability, controlling work-hardening rates, and ensuring final structural performance.
Composed of 99%+ pure aluminum, offering maximum ductility and minimal springback. Ideal for complex deep-drawn lighting reflectors, parabolic reflectors, and intricate decorative housings requiring mirror polishing or bright-dipping.
The industry standard for general industrial metal spinning. Manganese additions increase mechanical strength over 1100 aluminum while maintaining superior cold-forming characteristics for HVAC cowls, cookware, and fan housings.
Magnesium-alloyed aluminum providing high fatigue strength and exceptional marine-grade corrosion resistance. Commonly specified for automotive air tanks, marine fittings, and fuel storage vessels. Work-hardens faster than 3003, requiring controlled roller pass force.
Provides high structural yield strength and excellent machineability post-forming. Spun in the soft, ductile 'O' temper (T0) state to achieve severe plastic deformation, then solution heat-treated and artificially aged to T4 or T6 temper to regain full mechanical hardness. Widely used in aerospace nose cones, automotive wheel barrels, and structural drone housings.

We tailor our aluminum metal spinning workflows to match client volume demands, geometry complexity, and budgetary constraints.
Skilled artisans leverage hand tools and wooden or soft aluminum mandrels to form sheet blanks.
Low-volume production (1 to 200 units), artistic installations, and early-stage engineering prototypes.
Achieves standard tolerances of ±0.5 mm to ±1.0 mm.
Fully programmable multi-axis CNC spinning centers utilize hardened steel mandrels and hydraulic force rollers.
Medium- to high-volume production runs (500 to 100,000+ units) requiring high repeatability.
Delivers critical feature tolerances within ±0.10 mm to ±0.25 mm with integrated in-lathe edge trimming, bead rolling, and center-hole piercing.
Adhering to proven DFM guidelines during the initial product design stage prevents material tearing, excessive thinning, and tool chatter.
Aluminum typically experiences a 15% to 25% reduction in nominal wall thickness along steep conical or deep cylindrical sidewalls.
Engineering specifications should define minimum required wall thickness rather than rigid nominal values, allowing raw sheet stock thickness to be selected accordingly.
Internal Corner Radii: Maintain an internal corner radius of at least 2 to 3 times the starting sheet thickness (R ≥ 2t).
Transition Contours: Incorporate continuous, sweeping curves to allow even roller contact pressure and uniform metal flow over the arbor.
Sidewall Taper: Provide a minimum draft angle of 1.5° to 3° on deep cylindrical profiles to facilitate clean part ejection from the spinning arbor without surface scuffing.
Aluminum's chemical versatility allows for a wide array of protective and decorative post-processing options directly from our facility.
Converts the outer aluminum surface into a durable, corrosion-resistant aluminum oxide layer available in clear, black, or custom color dyes.
Creates high-specularity reflective surfaces on high-purity (1050/1070) aluminum optical reflectors.
High-durability polyester or epoxy powder coatings in matte, gloss, or textured finishes for outdoor light fixtures and HVAC cowls.
Secondary 3D multi-axis laser cutting for precise side-wall ports, mounting brackets, and TIG welding of mounting flanges or handles.
Comprehensive quality management systems ensure every spun aluminum part satisfies customer engineering drawings before shipment.
Maps complete part surface contours against native CAD models to verify profile tolerance compliance.
Non-destructively measures sidewall thinning across high-stretch zones.
Spectrophotometers and gloss meters inspect anodized or painted components under standardized lighting conditions.
