Use with hot runner molds

  1. 1

    End of leading product processing

    Remove the leading resin from the hopper and drain it into the cylinder.

  2. 2

    Preparations

    [ Detach the nozzle from the mold ]

    It is not necessary to change the processing temperature of the leading resin if it is within the operating temperature range of the Z CLEAN™ being used.

    If a dry color is used, the hopper should be carefully cleaned.

  3. 3

    Cleaning the inside of the barrel

    [ Loading Z CLEAN™ ]

    The normal amount of Z Clean™ to use is 3-5 shots at a full load (increase or decrease) based on the color concentration level.

    [ Injection purge with Z CLEAN™ ]

    Decreasing the screw speed will further improve the cleaning effectiveness.
    In the case of an open nozzle, the back pressure purge (*) further enhances the cleaning effect.

    Back pressure purging is a method of continuously discharging Z CLEAN™ by measuring while applying back pressure.

  4. 4

    Cleaning the inside of the hot runner mold

    [ Attach the nozzle of the mold ]

    It is not necessary to change the processing temperature of the leading resin if it is within the operating temperature range of the Z CLEAN™ being used.

    [ Purge the inside of the hot runner with Z CLEAN™ ]

    Return the settings of the molding machine to the conditions in which it injects into the mold.
    Also, the cleaning time can be shortened by performing a short cycle (cutting cooling time).

  5. 5

    Replacing the inside of the barrel with the succeeding resin

    [ Remove the nozzle from the mold ]

    [ Insert the subsequent resin ]

    Set the processing temperature for running the succeeding resin.

    Replace until Z Clean™ is no longer visible in the succeeding resin.

    Implement this process with the same volume used when cleaning the inside of the cylinder with Z CLEAN™.

  6. 6

    Replace the resin inside the hot runner mold with the succeeding resin

    [ Attach the nozzle to the mold ]

    Return the settings to the conditions in which it injects into the mold.

    Increasing the nozzle temperature 20 to 30c will make it easier to replace the succeeding resin.

    [ Purging injection with the subsequent resin ]

    Replace until Z CLEAN™ is switched to subsequent resin.

  7. 7

    Purging completed.
