The movement process of slider blade two-color molding:
The first hard rubber molding: blade slider is positioned forward and contacts the fixed mold cavity to seal glue. At this time, hard glue is injected through hot runner for the first time, so that hard glue is formed according to designed shape and size.
Second soft rubber molding: when hard rubber molding stage is completed, slider blade moves backward under control of oil cylinder, as slider blade moves backward, cross section of hard rubber is in contact with cavity of soft glue. At this time, melted glue of soft glue enters cavity through hot runner system to complete forming of soft glue.
