Theoretical Analysis and Verification of Plasticating Screw Characteristics for Injection Molding Machine

Abstract:

We have developed a plasticating simulation program for injection molding machines based on Chungs melting model. We compared the simulation results with the results of experiments which employed a visualization cylinder. The visualization cylinder has sight glass windows through which we can observe the melting phenomena in the cylinder. We established the temperature of resin in the cylinder by using infrared thermograph. The temperature of resin obtained by the simulation was close to experimental one. On the other hand, the solid-bed ratio deviated from the experiment results especially in the compression zone when the screw rotation speed was low. This suggests that the calculation of heat in the melting process should be improved.
