Extrusion casting film lamination machine

 Main functions and characteristics

1.This machine use the advanced electrical and mechanical device from the whole technical flow of basic material unwinding,winding,imported PLC control,HIM,achieve the separate control and central control linkage,has high automation;

2.Duplex basic material unwinding adopt automatic gas sensitive correction device,can substrate orientation and automatic correction control the basic material,unwinding,changing rollers use high speed without reduce speed automatically changing roller and cutting,unwinding tension force use vector inverter PLC control to ensure the basic material smooth substrate, and high-speed run effect;

3.Extrusion, forming speed is controlled by PLC, forming roller, silicone roller, auxiliary cooling rolls are made of recycled water cooling structure guarantee excellent results of composite lamination, forming roller clutch are used pneumatic control;

4. Duplex winding adopts vector inverter control, PLC control,changing rollers use high speed without reduce speed automatically changing roller and cutting


Suitable for PP,PE,BOPP,woven fabric,non-woven fabric,paper,aluminum foil,etc surface casting film laminate.Use special technology to produce strong adhesive fastness, thickness uniformity, good sealing performance products,its the most advance hot melt type lamination equipment.
