METAL SPINNING
Metal Spinning
Metal Spinning
Metal spinning is a precise forming process used to create hollow, symmetrical parts — most often circular in cross-section — by rotating a flat metal disc, known as a blank, at high speed on a lathe. As the blank spins, it is carefully pressed against a shaped tool or chuck mandrel that defines the interior contour of the finished part.
This controlled pressure gradually transforms the flat blank into a smooth, seamless three-dimensional shape without removing any material, ensuring strength, durability, and an excellent surface finish.
The most common shapes produced through metal spinning include hemispheres, cones, cylinders, bells, domes, and venturis. However, the process allows for endless customization — from simple geometric forms to complex, contoured profiles.
Metal spinning is valued for its cost efficiency, short lead times, and high material utilization, making it ideal for both prototype development and production runs. It is frequently used in architectural, lighting, decorative, and industrial applications where strength, precision, and aesthetic appeal are essential.
Typical metals used in the spinning process include copper, brass, aluminum, stainless steel, and zinc-coated steel, allowing for both structural and ornamental uses.
Copper Metal Spinning
The Copper Parts
Metal spinning allows us to create perfectly balanced, symmetrical finials with smooth curves and refined architectural profiles. This specialized forming technique is ideal for custom finials that require precision, strength, and elegant geometry.
Each spun finial component is then hand-finished, detailed, and assembled to meet exact architectural requirements. Whether for historic replication or contemporary design, metal spinning enables us to achieve refined shapes that elevate the finished structure.
Brass Metal Spinning
Decorative Metal Applications
Using traditional spinning methods combined with modern tooling, flat metal discs are shaped over custom molds to form seamless, rotationally symmetrical components. The result is a clean, continuous surface with exceptional structural integrity—perfect for ornamental roof details exposed to the elements.
Aluminum Metal Spinning
Specialized In Spinning
The result is a custom finial that combines timeless craftsmanship, precision forming, and long-term durability—designed to be seen, admired, and built to last.
Why metal spinning is ideal for finials:
-
Creates smooth, seamless forms with no visible joints
-
Ensures perfect symmetry and balance
-
Allows for custom profiles and proportions
-
Produces strong, lightweight components
-
Ideal for copper, zinc, and lead-coated copper
