Below is the ratio of the wire drawing dies, from 11.0-8.8, we use separate pressure dies(The purpose of using pressure dies for the first three positions is the wire strength is very strong, using pressure die can do a pre-treatment, and to increase the powder effect, to improve the lifespan), from 7.95-5.03 we use Nano dies, the capacity is around 700tons.
