  • PROCESS FOR PRODUCTION OF LONG MOLDINGS AND GLASS WITH MOLDING
    Publication number: 20100247951
    Abstract: An injection molding process for producing long moldings which is freed from short molding without enhancing the injection pressure. According to the molding process, a molten resin injected into a cavity (33) flows at a lowered flow rate in the interstice (34) between a protuberance (31) and a metal mold (22C) because the interstice (34) is narrower than the other part, while it flows sufficiently into the cavity (33) except the interstice (34) to adhere to a glass substrate (21) tightly. Further, the molten resin flows also into a lip-forming concavity (35) to form a lip having a high filling density.
