  • Patent number: 6821110
    Abstract: This invention consists of a new cost effective injection molding apparatus for molding with hot melt adhesives and other Polyamide materials. Manufactured from standard tubing components in a double “L” or “C” design, it has fewer moving parts than other molding machines therefore requiring less maintenance. It is specifically designed to not require the use of temperature limiting and maintenance prone heated hoses for transport of melted material or sliding injection nozzles for engagement into mold-set by utilizing a substantially fixed injection nozzle. It incorporates a sell-draining melt reservoir with single-side mounting to allow for heat expansion and has very short material transfer distance from reservoir to mold-set. It can utilize permanent nozzle engagement into the mold-set to simplify molding operation and reduce cost. It incorporates several safety features to protect operators against injuries.
