Bull Block Wire Drawing Machine

The Single/Double Deck Bull Block Non-Slip type wire drawing machines are designed for drawing of metals like Copper/Aluminium/Mild steel. The main body is made out of quality-grade cast iron. The transmission system consists of worm and worm wheel gears that are manufactured on sophisticated gear Hobbing machines. The die box is provided with two chambers for die sitting and for drawing compounds.

The spooler is either with friction clutch drive or with torque motor drive (at additional cost) for winding of drawn Bare Copper/Aluminium wire.

Medium wire Drawing Machine

Wire drawing machine is wet slip, stepped cone type suitable for drawing non-ferrous metals like Aluminium and Copper using a numbers of dies in tandem. The machines have horizontally mounted stepped capstans which is hardened and ground finished. The drive to individual capstan shaft is provided through Helical Gears manufactured on Hobbing machines. The gear train is housed in steel fabricated solid body and is oil immersed for smooth running. The die holders are adjustable and are provided between each capstan unit. Separate pipeline is provided over each die for forced lubrication and cleaning of dies. Various models like AII/MWD/13, AII/MWD/11,AII/MWD/9 to suit individual drawing requirements are available.
