Installation of Wax Blocks: Install the wax blocks onto the pins of the waxing mechanisms, then install the waxing disc into the guide cylinder, and subsequently install the annular end cover onto the end of the guide cylinder.

Installation of Strand: Install the same number of strands as the number of installation seats, one by one, onto the installation seats.

Manufacturing of Coarse Yarn: Select 3 polyethylene fibers with a certain fineness and twist them into coarse yarn through a twisting machine.

Manufacturing of Rope Yarn: Twist 6 strands of the coarse yarn into rope yarn through a twisting machine.

Manufacturing of Rope Strand: Twist 3 strands of the rope yarn into rope strand through a stranding machine.

Braiding of Rope: Braid 6 strands of the rope strand into a 6-strand cable core through a braiding machine.

Impregnation with Resin: Impregnate the 6-strand cable core.

Pre-tensioning Treatment: Use a specially designed tension machine to pre-tension the cable core. The tension should be 5 times the actual working tension of the cable rope, and the pre-tensioning time should be 30-40 seconds.

Drying: After pre-tensioning treatment, place the cable core on a rope rack to air dry or send it into a drying room for drying. Meanwhile, wind it into shape for later use.

Sheath Braiding:

Twisting: Select 3 polyethylene terephthalate (PET) filaments with a certain fineness and twist them into coarse yarn.

Twisting: Twist the 6 strands of coarse yarn through a twisting machine to make rope yarn.

Stranding: Form 3 strands of the twisted rope yarn into a spool of rope strand on a stranding machine that matches the size of the spindle of a double-layer braiding machine.

Braiding: Braid 30 strands of rope strand around the cable core into a sheath in one operation using a double-layer braiding machine.
