Acrylic & Plastic Spheres

Forgot your geometry lessons? That’s ok, most people have.

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.

Hemispheres can be made in a mold or free-blown.

To learn more about our hemispheres, please visit our Plastic Domes & Hemispheres page. We can also supply you with seamless, injection-blow-molded plastic spheres.

The pros and cons of each method are listed in the chart below:
