1. the manufacturing process of a filter element, it is characterised in that comprise the steps ofIn conjunction with wavy separation material and planar separation material:

  • in order to separate the wavy separation material of suspended contaminant, there is multiple ripplePeak, a relative outlet side and an entrance side and one first relative side and one second side, in wavy separation materialFirst side coating one combines glue-line and one first end face seal glue-line, and the first end face seal glue-line is coated with along outlet side, andAnd and outlet side interval setting;

    Then the of wavy separation material will be fitted in order to separating the planar separation material of suspended contaminantOn one side, two separate material binds mutually by combining glue-line and the first end face seal glue-line;

    Extruding two separation material;

    from the second side of wavy separation material, along the outlet side of wavy separation material, and from outlet sideTo the first end face seal glue-line of part, carry out pressing wavy separation material and form one first nip portion, the ripple of the first nip portionPeak is toppled over to the same side;

    Winding two separation material;

    be coated with one second end face seal glue-line in the second side of wavy separation material along entrance side, connectWinding two separation material and make two separation materials bind the shape after being fixed into winding by the second end face seal glue-line;

    Installing filter element frame;

    filter element frame is installed on two separation materials after winding, to form filter element.
