What equipment is used to produce throttle lines for automobiles and motorcycles?

My friend used to draw the odometer line of the brake line with the accelerator. This is actually very simple. When the raw steel wire and the outer rubber tube were brought here, they were bundled into a long bundle. Then cut them into different lengths with a straw cutter according to different needs, and then put the steel wire into a rubber tube, which is roughly how it is produced. However, my friend thinks that he can't make money, so he won't do it now!
