A: The first large die than a cable diameter 1.0 ~ 3.0mm, the second mold into a cable diameter than the small 0 ~ 0.6mm. The third smaller die diameter than a cable 0 ~ 0.2mm, the actual use of the mold also note that the cable in the mold can not swing, the hand switch to the cable core does not feel loose, insulated core die and the friction produces heat should not be hot. Insulated core to smooth out the die surface trace no injury marks.
