Equipment Control Lab Blowing Film Machine

Equipment control lab film blowing machine The blowing film machine consisted of single screw extruder and film blowing tower, it is mainly used for testing the film blowing feasibility of polymer materials and the colloid status contained in the materials. Equipment control blowing film machine is equipped with PID/LED/RKC intelligent digital temperature control, high-precision digital instrument display. Can be used for testing the dispersive property of color masterbatch and material processing properties. Parameters: 1.
