Outside Dia. Control System

  • These units are to control diameter by outputting feed-back signals to extruding machine or winding machine in continuous extruding molding production line.
  • Among the range, there are DAC-76A(Step delay control type), DAC-86B(PI control type) and DAC+88(Automatic starting-up type).
  • There is LDM-210C that builds the control unit into the measuring instrument of the LASER DIAMETER.  
  • Among the range, there is deformed material extruding control system for keeping shape of profile constant of extruding plastic or resin

Defromed material extruding control system Specificaion
Summary This system is for keeping shape of profile constant through direct compensation/control of extruding machine or drawing machine by measuring in Non-contact method a discrepancy from standard value of profile to be extruded with a detecting head to be set just behind extruding machine at the time when extruding plastic or resin.
Edge sensor Sensing method Non-contact/Infrared optical fiber sensing
