The advantages of this type is that high speed high capacity,for example,it can draw the steel wire from diameter 6.5 mm to 4 mm by one time,ie from first unit 6.5-5.6 mm,second unit from 5.6-4.8 mm,from 4.8 -4.0 mm,after this,then discharge the wire to make nails directly.

While if use the single type horizontal wire drawing machine,it needs 3 times drawing,ie from 6.5-5.6 mm by one time,then discharge the wire to wire reel,then start drawing like first time again,this will waste a lot time and efforts.

Usually 1 set 3-1 type combined type wire drawing machine can meet the capacity of 3 automatic nail making machines,while 1 set single wire drawing machine can only meet the capacity of 1 nail making machines.At the same time,it will need 2 more workers if using 3 sets horizontal single type wire drawing machine.

All these 2 kinds can draw steel wire from diameter from 6.5 mm to diameter 2.2mm,if you want smaller diameter,then you need the cistern type wire drawing machine.
