There are some processes using photo-setting resin to pull and squeeze, which are mainly applied to the reinforced core product of optical cable in the existing market, but the process is not used at present, and the reason is that the design of the pulling and squeezing process and the mould is similar to the thermal setting pulling and squeezing process, and the light energy and the light intensity of the selected ultraviolet curing mechanism can not meet the requirement of high-speed production.
