Metal Hemispheres

These featured metal hemispheres are manufactured by us for aerospace and geological applications and other uses. Working with aluminum, copper, brass, steel, and other materials, we apply a combination of CNC metal spinning, hot spinning, machining, welding, and polishing to fabricate our spheres.

We can achieve up to a #4 brush finish, and hold tight tolerances down to 0.005 of an inch. Final material thicknesses range from 0.018 of an inch to ¾ of an inch, with a maximum 60″ outside diameter width and a maximum 30″ product height.

We’re happy to accommodate orders between 1 and 50,000 pieces. To learn more about our metal hemispheres, please contact Helander Metal Spinning Company.

Metal Cone and “Bullet” Shapes

Appropriate for a range of industries, such as concrete testing, alternative energy, and soil testing, these featured metal cone and bullet shapes are manufactured using a combination of CNC metal spinning, hydroforming, and double roller shear forming.

We can fabricate these metal shapes from aluminum, copper, brass, stainless steel, or carbon steel, and we offer either zinc plating or #4 polish material finish.

We feature a material thickness between 0.030″ and 0.250″, and can achieve a maximum product outside diameter of 48″ and a product height up to 36″. Our superior methods enable us to hold tolerances down to +/- 0.010″, and we can handle orders of up to 50,000 pieces. To learn more about out metal cone and bullet shapes, please contact us today.
