LargeFunction: Stretch Film Machine is a new machine designed by our company. Mainly composition by a set of small Cast film machine. Cast film machine was designed for Rubber molding material cast film products.It mainly use for Cast film products molding, cast molding material formulation development, cast molding material properties and other research areas.for example .let the material transported to the casting mechanism to take the cast film products, etc. The best function is light and useful.This lab cast film machine has compact structure and good performance.During use it.Cast roll and the draw roll speed of the motor through the inverter to controlled so that the conveying speed of the material can be adjusted to meet the user requirements and then preparing various sheet product....
Features:
u Extrusion device：Barre and screw is main parts of this machine. Plasticization and Extrusion progress complete in here。Barre and screw both use high quality nitride steel 38CrMoALA，a weeks of surface treatment by use nitrogen treatment，Have high hardness.Abrasion Resistance and corrosion resistance. etc..extend of service life
u This machine Barre heating by use MICA heater, outside cover Stainless steel ，Beautiful and energy-saving, good heat resistance, long life, heat evenly, easy to replace；fan cooling have channel (Automatically open cooling fan when over-temperature ),easy to cool.
u transmission gear：Driving motor directly connect with reduce gear motor.，reducer output shaft connect with screw，drive screw rotation. The transmission compact structure, smooth, strong bearing pressure.
Principle: this machine include :Drive motor. transmission gear. Extrusion device.hopper. Electronic control system.Cast Film die .Two roll calender and so on
Working principle: Raw materials from the hopper into the extruder through plasticizing and extruding cast into the state, and then from the host through the die head two roll calender to calendaring
