• Smart injection machines and their adjustment principles under Industry 4.0

  Monday, April 15, 2019

  To attain accurate mold filling analyses, we must consider a machine’s movements, including screw acceleration and deceleration in the injection process; the machine reaction at the moment when filling turns into packing; and the machine’s protection behaviors for preventing injection pressure from being too high. Currently, the core of molding equipment is injection machines. Therefore, under Industry 4.0, smart machine applications will rely on injection machine design. In this article, we will discuss how injection machine manufacturers apply injection information collected from the injection process to enhance product quality.
