Abstract
A method of and an apparatus for measuring and evaluating characteristics of material resin using an injection molding machine. Injections of resin are performed with different resin temperatures TCi and different injection velocities Vj to detect injection pressures Pr at set screw positions. Data of combinations (Pr, V, TC) of an N number of injection pressures, injection velocities and resin temperatures are obtained. An interdependency relation function P(t, v(x),x) expressing correlation among the injection pressure, the injection velocity and the resin temperature is obtained as P(t, v(x), x)=A(x)ev(x)according to a least square method using the obtained data, where β(x) represents a degree of dependency on injection velocity influencing the injection pressure and 'log A(x)−α(x)T' represents a degree of dependency on resin temperature influencing the injection pressure.
