Acrylic & Plastic Spheres

A globe or sphere is a complete ball. We make most of our plastic spheres by bonding two plastic hemispheres together, then sanding and polishing the seams. This allows us to build large Plastic Spheres that maintain good strength and structural integrity.

To learn more about our hemispheres, please visit our Plastic Domes & Hemispheres page.

CDS can also manufacture seamless, injection-blow-molded plastic spheres. Blow molded sphere wall thickness becomes an issue on larger spheres, so blow molding makes the most sense for smaller plastic spheres.

Our plastic spheres are most commonly constructed of either polycarbonate or acrylic.
