People in the building materials business know that wire drawing is a complicated project! I used to be a worker, specializing in plastic-steel doors and windows, and every time I used gloves and brute force to make an aluminum window into a regular shape! At the same time, use some grinding wheels to polish it, and it often takes an hour to make a good one! Laborious and time-consuming! Really a bit thankless feeling! At that time, there was no idea of the existence of wire drawing dies! Later, when I was visiting the building materials market again, I found such a machine that can compress and polish metals such as aluminum and steel into the shape I need. At that time, I was a little skeptical. So let the boss give me a demonstration on the spot! Facts have proved that this is feasible! when Wire drawing die I was overjoyed and bought one on the spot! Because our processing plant is paid by piece. At that time, the work efficiency increased by more than 50%! Moreover, the specifications are very in line with the needs, and there is never any need for rework or anything! The drawing die is really good and easy to use!
