Spun Products

Keystone has developed proprietary technology for the near-net spin-forming of precision components for various launch vehicle and satellite applications.  Keystone makes the best use of stock metal sheet and plate materials to reduce cost and lead times.  The ability to spin to near-net conditions creates a minimum of finish machining, further enhancing Keystone’s cost and lead time advantage.  Keystone uses both conventional and CNC processes to produce high quality dome products ranging in diameter from 5 to 190 inches.  Available dome materials include aluminum, titanium, stainless steel and high nickel alloys.  Keystone’s Ontario, CA facility is dedicated to large spun-formed products.
