Abstract
A method for injecting plastic material or another injectable material into an injection molding tool comprises the following steps: plasticizing the plastic or other injectable material in a plasticizing apparatus ( ); transporting the plasticized plastic or the plasticized other injectable material into a dosing apparatus ( ), which has a fluidic connection ( ) to the plasticizer apparatus ( ), and specifically in essentially precisely the quantity that is to be introduced into the injection molding tool ( ); transporting the plasticized plastic or the plasticized other injectable material, essentially in that quantity which is to be introduced into the injection molding tool ( ), from the metering apparatus ( ) into an injection apparatus ( ), via a fluidic connection ( ), while at the same time preventing the plastic or other injectable material from backflowing from the metering apparatus ( ) into the plasticizing apparatus ( ); injecting the entire quantity of plastic or the entire quantity of another injectable material, which is situated in the injection apparatus ( ), into the injection molding tool ( ), while at the same time preventing the plastic or the other injectable material from flowing from the injection apparatus ( ) back into the metering apparatus ( ). In this way the production of small and ultra-small injection molded parts is facilitated, and the injection of a reproducibly precise quantity of melt is accomplished.
