Product Description

Laboratory three layer film forming system, can be used for multilayer film casting & chilling or multilayer film & sheet preparation by compression depending on the different construction of the units. The system consists of three extruders, a three layer distributor and a die, film casting or chilling or compression dual driven roller system and film edge cutting, flattening, taking up and winding system.


20T Extruders
•Height of the die out put 1000±130 mm adjustable continuously
•Angle of die out put horizontal ±15° adjustable continuously
•Twin PID temperature control of extruder barrel (electrical heating and compressed air cooling)
•Real time monitoring of extruding material flow rate by automatic weighing system
•Changeable configuration because of modular design



Three layer casting die head
•More than 10 independent temperature control zone
•Static mixer for every layer material feeding
•Pressure monitoring for every layer feeding
•Flow rate adjust function for every layer mixer
•Non dead point design of flow pass into mold
•High mirror polishing of Mold flow surface


Film forming system
•Pneumatic driven up roller 45mm range .
•0~2mm gap between rollers adjustable
•20m/min line speed maximum
•300mm effective width of the roller


Flow pass design inside dual driven rollers for temperature control, Temperature monitoring of the flow outlet .
Independent adjustment of fluid flow rate inside dual driven rollers based on set temperature

Circulating fluid (water or oil) cooling for constant temperature control by means of heat exchange medium connection ..
Dual driven roller system configured horizontally orverticality

Multilayer film casting or compression process achieved by using different driven roller system

Servo-motor application for dual driven rollers and take up device
Working height of extruding film 1000±50 mm adjustable

Wind knife/edge cutting/flattening

•Tension constant taking up and shaftless winding of the film
•Toque constant taking up of edge film
