Cascade injection control


cascade injection control

The cascade injection control assembly is used to control pneumatic cylinders that allow sequential injection of mass into injection molds. The whole cascade injection control process depends on the path of movement of the injection piston.


The KSV series devices are supplied as standard with the possibility of controlling 1 - 10 solenoid valves with a working pressure up to 16 bar. These valves control the opening and closing of 10 pneumatic cylinders depending on the injection length and the position of the optical ruler according to the path of movement of the piston of the injection molding machine. Possibility of opening and closing up to 3 positions on each pneumatic cylinder during one injection cycle. The optical ruler is located directly on the injection molding machine and records the initial position of the machine, the injection length and the current position. The KSV is equipped with a 7 ”TFT LCD touch control (color) control panel. The whole process is controlled by a microcontroller. It provides control of operating and error states, as well as the subsequent possibility to reprogram individual recipes. KSV software is developed for easy and intuitive operation and allows testing of individual recipes (programs) - a library with memory of up to 10 recipes. Possibility of communication via Ethernet. The device is equipped with an alarm beacon, which announces error states, always in the event of a change in the program and its non-testing, or. subsequent non-storage. The KSV is designed so that at least one pneumatic cylinder is always open along the entire injection length during the injection molding process. Thanks to this solution, there will be no possible overpressure and damage to the mold or. nozzles and hot runners.
