Abstract : The invention comprises a method for extruding a plastic explosive composition such as PBXN-301 into small channels in plastic or other low yield material. The new method, broadly stated involves applying a low level of pressure (1000 to 2000 psi) combined with an ultrasonic vibration to aide extrusion of plastic bonded explosives into the channels. The invention is usually accomplished with a specially designed nozzle, a curved coupler, that is an acoustically tuned exponential horn and conventional extrusion apparatus in combination with an ultra sonic transducer that applies at least 20,000 Hertze per sec. to the extruder.
