Features: 1) Principal electric motor driving on the wire drawing principal axis and winding axis through a flat belt or a gear chain, through wimble drive to winding system and achieve the drawing & winding finally 2) Tin wire put into the draw-extend room through wire setting rack, go through tower wheel, then draw by the wire drawing model, cooling mode is spray or water logging 3) The wire will traverse pulling wheel, wire passing idler pulley, wire setting wheel and then enter into wire receiving tray and finished the process at last 4) Adopts top quality timing electric motor, principal axis processed by digital boring lathe in order to keep the homocentricity of the axis & the machine 5) Model seat adopt Germany's enchase technique to protect the model from being damaged 6) Wire stretching axes is the middle carbon steel S45C treated by high frequency 7) Tower wheel was forging the ball carbon S45C steel and heat-treated b
