What are the wire drawing process

The process characteristics of wire/rod drawing consists of 

(1) Pulling of the wire rod/round through the die to reduce its diameter, 

(2) Drawing increases the length of the wire/rod as its diameter decreases,

 (3) Several dies are used in succession (tandem) for small diameter wire,

(4)At last ,the wire rod/round will be smaller ,but the length will longer .and more suitable in somewhere  and more valuable
