DAC/PRF Series - Outside Diameter Control System

These units control diameter by outputting feedback signals to extruding machine or winding machine in continuous extruding molding production line

The range consists of DAC-76A(Step delay control type), DAC-86B(PI control type) and DAC+88(Automatic starting-up type).

The LDM-210C builds the control unit into the measuring instrument of the LASER DIAMETER.

Deformed material extruding control systems (DRF-10H, DRF-40H and DRF-93) keep shape of profile constant by extruding plastic or resin

Deformed Material Extruding Control System

This system helps keep the 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.
