Abstract:
A method for setting a program profile in the control of an injection speed of injecting molding machines, in which a moving speed of an injection plunger in a forward direction such that the mold cavity will be filled is controlled by the program profile in accordance with a position of a plunger, comprising:inputting into a profile setting means values for the following items:a switching position of the injection plunger when an injecting phase is changed from a melt material filling phase to a dwelling phase;one of a desired filling stroke for the injection phase and a starting position of the plunger for the injection phase;a maximum speed of the profile;an initial speed of the profile; anda period during which said initial speed remains constant; andautomatically using the profile setting means to set up the program profile, wherein the program profile results in a prosecuting profile which satisfies the values input into the profile setting means.
