Beginning in April 2008, the technical center at Austria-based SML Maschinengesellschaft mbH will
make a new sleeve touch co-extrusion line available to customers for conducting trials for a wide
range of products and applications using their own raw materials.
The pilot plant will feature a five-layer feedblock attached to three extruders, resulting in
an output of 425 kilograms per hour (kg/hr) for polypropylene, 380 kg/hr for polycarbonate and 600
kg/hr for amorphous polyethylene/polyethylene terephthalate glycol; and 1,050-millimeter-wide
rollers on downstream equipment. It also can be fitted with a sleeve touch system, coating module,
calender roller or airknife. The addition of a haul off unit will enable in-line lamination.
The line can achieve speeds of up to 100 meters per minute for production of thin sheet or
coating applications by utilizing the fully automatic winder series 1100, including robot bobbin
handling. It also can produce part bobbins using friction winding shafts.
Additional features include: a degassing extruder, which eliminates the need for preliminary
granulate drying; and high-temperature calendering rollers to enable the manufacture of
polycarbonate and cyclic olefin copolymer sheet for optical applications.
