engineered hollow shells

Deep Springs Technology (DST) is the world leader in small hollow shell manufacturing. We manufacture high quality shells for industrial, commercial, and military applications. Our shells can be fabricated from various materials such as metal, glass, or ceramics, including silicon carbide. Shells can be fabricated in custom shapes, including spherical , right cylindrical, flat oval, or hexagonal. Additionally, our shells can hermetically encapsulate virtually any gas or gas mixture. Size of shells can range from 0.5mm to 3.0mm diameter (larger or smaller are possible). DST shells are currently being used in armor plating, buoyancy, thermal, and other applications. Contact us to discuss how to incorporate our shells into your application.

Hollow shells are highly adaptive materials possessing many superb characteristics such as high energy absorption and vibration and acoustic dampening. They also have very high specific strength and are far better thermal insulators then solids materials. These attributes are what make hollow shells perfect for multifunctional applications where all of the previously mentioned conditions are present.
