Brief Introduction Of Operation Principle Of Blow Molding Machine
Jul 26, 2017

In the production process of blown plastic film, the uniformity of thin film thickness is a key index, in which the longitudinal thickness uniformity can be controlled by extrusion and traction speed stability, while the thickness uniformity of thin film is generally based on the precision manufacture of die-head, and with the change of production process parameters, in order to improve the film transverse thickness uniformity, the introduction of automatic transverse thickness control system, commonly used control methods have automatic die Head (thermal expansion screw control) and automatic wind ring, here mainly introduce the principle and application of automatic wind ring.
