Applied with hand protection system at the feeding area on the basis of the 6th Generation Rubber Extruder, safety improved. Multistage filtration systemfor the vacuum system, effectively improve the service life of the vacuum pump.38CrMoAL alloy material integration body, no solder points, improving the coaxial degree of the fuselage assembly to prevent barrel scratching phenomenons, enhancing the barrel processing precision as well as adopting the nitriding treatment, the rubber screw is treated by spraying alloyservice, thus the service life is strongly improved.PLC system to storage the technical production data and HMI, more intelligent, more convenient.
