Specifications of EPE Foam Sheet Extrusion Line

Components of  EPE Foam Extruding Plant     

  Screw:       It is made of the top quality *8CrMoALA azotized steel. Thermal and azotized treatment and      special surface plating made the screw with the characteristics of high intensity and long life.

   Cylinder:       It is made with top quality  *8CrMoALA azotized steel. Thermal treatment prevents wearing from long time service.

    Material-Feeding Sector:     Two ends are connected to the cylinder and the gear box. The raw material is sent to the extruder via it. The user should keep some cooling water in circulation in order to prevent the temperature arising, which will result in pastiness and agglomeration of the raw-material, even block the material-feeding hole.

   Main-Motor of Extruder:     The main motor is an adjustable AC motor,  cooled by air. Main motor is connected to the screw in the main machine via the gear box.

       Foaming agent (Butane) Pump: is a high pressure measuring pump. This pump jets the deliquesced butane into cylinder by a high-pressure of ****5Mpa (*******0Kg/cm).The butane mixes with the melted LDPE in the entrance of the machine cylinder. A non-return valve is equipped in the entrance of butane into the cylinder to insure the melted LDPE will never shoot back in case that the pressure in the cylinder is higher than the butane pressure. This is also to insure production safety.

      Anti-Shrinkage (GMS)  Agent Pump:  sends the heated shrink- resistant agent into cylinder with a pressure of ****5Mpa (******0mm/cm).The melted shrinkage resistant agent is mixed with LDPE in the shrinkage resistant agent's entering sector. A non-return valve is equipped in the entering sector to prevent the melted LDPE from shooting back in case that the pressure in the cylinder is higher tha   n the shrinkage resistant agent's. This is to insure the production safety.

     Die-Head: Melted raw material is extruded from this sector. The raw material started to froth at entering the die-lip. The thickness of the expanded PE sheet depends on the die lip and drawing speed. .

     Molding Drum: The width of the expanded PE sheet relies on this sector

     Haul-off:   The sheets extended by the molding drum should be draught after entering this sector. At this time the drawing speed should keep balanced in order to insure the quality of the sheet material. equipped with a speed-changeable motor so as to timing the drawing speed. 

     Winder: This part is equipped with length counter to set the sheet's length. It rotates **0 degrees when the winding length of the first roller reaches the set requirements. Then the second roller starts winding.
