    摘要： An injection molding machine includes a cylinder (41) that heats a molding material which is filled with the inside of a mold unit (30); a feeding member (43) that feeds the molding material within the cylinder (41); a drive device (46) that moves the feeding member (43) forward and backward; and a controller (70) that carries out a filling process of driving the drive device (46) to control the speed of the feeding member (43), and a hold pressure process of driving the drive device to control pressure acting on the molding material from the feeding member (43). The controller (70) performs switchover from the filling process to the hold pressure process on the basis of a detection result of a detector (37) that detects the arrival of the molding material within the mold unit (30) to a predetermined position.

    摘要： The invention relates to a method for qualitatively and/or quantitatively classifying injection-molding tools in tool categories and determining preferred intervention ranges and/or manipulated variables for adapting injection-molding machine parameters in the case of changing ambient conditions and/or determining the influence of disturbing effects on the injection-molding process, comprising the following steps: a) providing an injection-molding machine having the injection-molding tool which is to be classified and which is intended for the determination, b) performing at least one injection-molding cycle with injection-molding machine settings in order to obtain a qualitatively adequate injection-molding part, c) determining a quotient Q=Δp/Δs or Q=Δs
    n /Δs
    e characterizing the tool from c.1) a pressure rise Δp during the compression phase of the injection-molding cycle and the melt volume ΔV displaced during the compression phase or c.2) a melt volume ΔV
    n displaced during the holding-pressure phase and the melt volume ΔV
    e displaced during the injection phase, wherein c.3) the corresponding screw travel Δs, Δs
    n , and Δs
    e is measured in order to determine the displaced volumes ΔV, ΔV
    n , and ΔV
    e , d) providing at least one limit value (G
    1 ......G
    x ......G
    n ), wherein one or more recommendations for preferred intervention ranges or manipulated variables for adapting adjustment parameters of the injection-molding machine are associated with ranges (Q 1 ; G
    1 2 ;... G
    n-1 n ; Q > G
    n ) for the values of the quotient Q, e) determining in which of the ranges (Q 1 ; G
    1 2 ;... G
    n-1 n ; Q > G
    n ) the value of the quotient Q lies, and f) outputting the preferred intervention ranges and/or manipulated variables for adapting the machine parameters of the injection-molding machine which are associated with the determined range.
