ABS sheet production line

ABS plastic sheetproduction line The FLAT DIE can be supplied either for sheet or for plate production. The available die widths ranges from 700mm to 1700mm. The thickness varies from 0,2mm to 8 mm. All dies are made of two blocks by thermically treated steel. The upper lip is flexible, adjustable with bolts of differential thread, which permit micrometric adjustment. There is an inside flexible bar for flow adjusting. Adjustable deckles determine the sheet width. Before the flat die, a COEXTRUSION BLOCK can be inserted, to connect one or more extruders. The LJC CALENDERS are divided into four basic models, identified by the rolls diameter: 750-500-350-250 mm. The calender and the haul-off can be made in one only structure for 250 and 350 mm versions; or in 2-3 pieces ( calender-extra cooling roll-haul off) for the 500 and the 750 mm versions. The calender is made up of a base in thermowelded laminate and a frame of thickly bolted laminate . The main structure is made up of 3 cylinders on a vertical axis: 1st Upper cylinder, calibrator and cooler, applied on mobile arms moved by pneumatic pistons 2nd Central cylinder, calibrator and cooler, applied on rigid arms 3rd Lower cylinder, calibrator and cooler, applied on mobile arms moved by pneumatic pistons
