System and method for injection moulding of thermoplastics and thermoplastic elastomers in an injection moulding machine for injection moulding details of different weight, size and shape simultaneously in only one process cycle, and incorporating a feeder block (1), a number of hot moulding modules (4, 5), each connected to its own one of a number of flow channels (2) provided in the feeder block, a torpedo (9) provided in the flow channel for each hot moulding module and intended for stepless adjustment of the melt flow through the module, and means for causing final filling, compression and change-over to and maintaining of post pressure, and a control unit for individual control and supervision of the processes in the different hot moulding modules, whereby the flow channel of the hot moulding module is provided with a movable bar (14) extending axially therethrough, and which at its forward end is designed as a ram (15, 16), which is adapted to operate in a melt channel space (17) downstream of the torpedo (9) for causing final filling, compression, change-over to post pressure and maintaining this, and which bar is connected to an individual driving device arranged to give the bar axial motion and pressure force under control from the control unit. |
