Controller and control method for aluminum shape extruder

摘要

A controller for an aluminum shape extruder includes a laser speed sensor for detecting operating speed of a hydraulic unit of the aluminum shape extruder and a computer control unit for controlling the operating speed of the hydraulic unit and control method for an aluminum shape extruder comprises the steps of using a laser speed sensor to detect the operating speed of a hydraulic unit of the aluminum shape extruder, storing the operating speed detected by the laser speed sensor in a computer memory, comparing the detected operating speed with a set value to obtain a comparison value, and computer controlling the operating speed of the hydraulic unit of the aluminum shape extruder using the comparison signal.
