Hot runner injection molding machine can be viewed as an extension of the injection mold part

Hot runner injection molding machine can be viewed as an extension of a portion of the injection mold . It connects the nozzle and the mold cavity injection molding machines , injection molding machine to transport molten plastic into the cavity inside . Different from the traditional cold runner , it has its own heating system or  Instrument valve manifolds  , thus maintaining the flow passage times during the molding of the plastic in a molten state . In the mold opening the mold, the plastic melt flow is not solidified waste removed and remain in the flow path of the melt can be injected into the next injection mold cavity , to improve the material utilization . Hot runner injection molding technology is a revolution in technology , injection molding technology is an important development direction. Molding hot runner injection mold industrial development as a cutting-edge technology , is currently dominated by a small number of famous  Valve manifolds  and American runner company has developed and commercialized . This technology in the country is still in the gradual promotion phase, good prospects , the potential market is large, hot runner technology development and application is imperative. Carried out on the theory and design of hot runner technology point of exploration, undoubtedly contributed to the popularity of hot runner technology in China and faster application development in order to shorten the runner with foreign advanced level of technology gap. Hot runner system to ensure thermal equilibrium state is one of the key technologies of hot runner .
