Reel is made from ZG270-500 and coated with carbon tungsten powder. Surface hardness: >HRC60; finish: 1.6Ra; service life: > 2 years
Cooling: narrow-slit type water cooling inside the reel; forced slot type annular air cooling outside the reel
Mold box is a welded part and comes with 2 cavities separately for lubrication powder and cooling water (direct water-cooled). Mixing device is available in the lubrication cavity.
Transmission is done by V-belt and gearbox
Tension is adjusted by rollers pneumatically. The sensor adopts non-contact angular displacement. Mold is compensated automatically after it is worn.
AC variable frequency control is employed for the electrical control system, which adopts inverter from Siemens or Inovance
The system adopts PLC control from Siemens or Mitsubishi
The touch screen is from Taiwan, and low-pressure electrical elements are from well-known brands in China
Each machine is designed with the operations of start, stop, emergency stop, etc. Users can set the speed, wire diameter, and check the working speed and error through the touch screen. The console is set with the buttons of start, stop, emergency stop, accelerate, decelerate, and error indication
