Abstract
A closed loop feedback control for a high pressure impingement mixing system. The high pressure impingement mixing device is equipped with a circulation loop containing both a pressure sensor and a flow volume meter. Constant pressure and flow volume is achieved by continuous closed feedback loop monitoring of the pressure and flow volume to effect a change in an adjustable pump setting and servo displaceable nozzle needle. The nozzle needle adjustment allows maintaining the appropriate pressure and volume on a continuous spaces. It also allows altering component ratios and/or flow volumes during a shot in order to affect a change in material or flow characteristics of a produced part.
