Film Extrusion Line

Film extrusion production line is a kind of screw plastic extruder. The working mechanism of plastic film extrusion machine is to fully plasticize the materials by relying on the pressure and shear force generated by screw rotation and evenly mix and shape through the die; Therefore, sometimes one plastic film extrusion machine can complete a series of processes such as mixing, plasticization, and molding at the same time, so as to realize continuous production.

FAQ about Film Extrusion Line

In Film cast extrusion, is there any relationship between die width and thickness of the film?

In the process of film extrusion molding, the width of the film has the most direct relationship with the width of the die. In the process of back molding, the shrinkage of different materials may also have a certain impact on the width of the film, but the most direct factor of the film width depends on the width of the die.
What are the applications of Film Extrusion Line?

Plastic film has a wide range of applications in life. Jwell company routinely has TPU film extrusion line, EVA, Poe, PE, PVB, SGP, and other plastic film extrusion production lines. Its products are used in various fields such as automobile, shoe material, ready-made clothing, inflatable toys, water, and underwater sports equipment, medical equipment, fitness equipment, automobile seat materials, umbrellas, bags, packaging materials, optics, military industry, and so on.

Main Process of Film Extrusion Line

The production process of the film extrusion production line is as follows:
Prepare raw materials - raw materials enter the feeding machine, enter the main machine hopper through the feeding machine - feed by the film extruder, mix through the screw, shear and plasticize - extrude the plasticized materials through the screw, filter impurities through the flow channel, or conduct secondary plasticization through the metering pump - after passing through the flow channel, the plasticized and filtered materials enter the mold for forming - after the mold is formed, the raw materials enter the three roller press, Adjust the thickness and control the width after stretching - press and enter the cooling support for cooling and forming - then pull back by the tractor - the finished product winder rolls up the final finished product after complete cooling.
