          Attentions 注意事項:
          1)The compound should be dried before using if the package is broken. Once package is open, recommend to run out within 12 hours.
          原料破包需烘干后才能使用,材料一經開封,建議12小時之內用完。
          2)Please ensure the screw, barrel, hopper are thoroughly cleaned before operation. Avoid bringing impurities while processing.
          加工前確保螺桿、機筒、加料斗徹底清理干凈,加工過程中嚴禁帶入雜質。
          3)If you need a faster extrusion. Please accelerate screw speed gradually to avoid inadequate plasticizing which may cause rough surface of the cables.
          如果要快速擠出時,請慢慢逐漸加快螺桿轉速,以免塑化不良,電纜表面毛糙。
