Abstract:
A method for injecting material into an injection molding tool, comprising:providing a plasticizer unit with a longitudinal axis, a metering apparatus with a longitudinal axis and an injection apparatus with a longitudinal axis, each longitudinal axis being disposed at an angle to one another and meeting at a fluidic connection; melting the material in the plasticizer unit; transporting the material from the plasticizer unit into the metering apparatus via the fluidic connection; metering in the metering apparatus a precise quantity to be introduced into the molding tool; transporting the material, in the quantity which is to be introduced into the molding tool, from the metering apparatus into the injection apparatus, via said fluidic connection, while at the same time preventing the material from backflowing from the metering apparatus to the plasticizer unit, the metering apparatus having a uniform width in communication with and substantially all the way to the injection apparatus; and injecting the material, which is situated in the injection apparatus in the quantity to be introduced in the molding tool, into the molding tool, while at the same time preventing the material from flowing from the injection apparatus back into the metering apparatus.
