Abstract
Injection-compression molding of large size molded products requires the elaborate consideration for multi gates designing and adjustment to control resin filling balance, although stable molding is still difficult if waste or composite plastics are used as materials, which have unstable fluidity. Our research aims at the flexible resin filling flow control by die tilting in injection-compression molding. In this paper, the effectiveness of die tilting is verified in an actual molding machine, and the effects of tilting angle and resin fluidity on the filling balance are examined in a testing machine. It is found that the flow balance varies linearly with the tilting angle and is independent of the fluidity.
