Direct Mounting

The idea of using the speed and power of ammunition technologies for fast and repetitive mounting processes was first implemented during the Second World War. With the help of powder actuated tools a lot of damaged ships could be repaired much more efficiently than by welding or drilling after a small damage. A market success of modern pyrotechnical mounting was achieved by the brothers Martin and Eugen Hilti from the Principality of Liechtenstein. In 1953 they launched the first powder actuated tool shortly after the invention of a pneumatic nail gun in the USA.

RUAG Ammotec produces propellants for modern powder actuated tools. Blank cartridges provide for thrusting the butt, which drives the respective fastener, normally a nail, into the specified position with a precisely defined amount of energy. The cartridges of RUAG Ammotec allow performing the operations of direct mounting in just one step. Previously this process required three individual operations of boring a hole, inserting the dowel pin and tapping the screw.
