High precision FIFO injection system
The plasticising cylinder is fixed directly to the side of the injection piston and connected via a filler channel in the injection piston. At the end of the injection piston is a ball check valve with a small diameter for maximum precision. This arrangement enables a small injection piston diameter, which results in the high repeatability of the system. Due to the small piston diameter and the resultant small diameter of the injection cylinder, it is also possible for the opening in the machine plate to be very small. This results in optimum conditions in terms of the deflection of the injection-side fixing plate.
