Laboratory cast film auxiliary machine supports full-process film casting with matching extruders. It integrates multiple functions including casting, traction, trimming, edge recycling and winding. Adopting independent servo drive and intelligent measurement & control system, it delivers high-precision and stable film sample production. Ideal for polymer formula development, process optimization and material performance testing with customizable structure and parameters.
Product Introduction
Laboratory cast film auxiliary machine is composed of one set of melt pump, one set of extrusion die head and one set of casting unit. Integrating the casting system, traction system, winding system, edge trimming & recovery system as well as measurement & control system, this equipment works with matched extruders to complete the whole process of polymer extrusion, casting, traction, edge trimming and winding.It is widely adopted for the manufacture of packaging films, optical films, medical sheets and electronic sheets. Meanwhile, it serves for polymer property research, extrusion formula development, process optimization, cost control and small-batch trial production of polymer materials.
