Method of controlling a molding system

摘要

A method of controlling a molding system for fabricating a molded article from a settable mixture includes the steps of priming several discharge containers with different components of the settable mixture and evacuating the discharge containers through a conduit into a mixing head. The mixing head combines the components to form the settable mixture that is then injected into the mold. During the priming step, pressure within each of the discharge containers is monitored to detect air being drawn into the system. Pressure of the settable mixture is monitored at the mixing head and at the mold tool to detect any blockages that can cause damaging pressure fluctuations. To prevent built up of residual settable mixture within the settable mixture, all parts of the system that contact the settable mixture are flushed with a solvent and then air-dried to rid the system of the solvent.
