Sheet / Film Extrusion is the process which is used for the products like plastic sheets or films. During the extrusion of these plastic materials, the required cooling is achieved by the action of pulling which is done through a specific set of cooling rolls that are generally three or four in number. These cooling rolls are also called calender or "chill" rolls. Extremely fast running speed develops "nerve", which is an undesirable condition. This condition occurs when insufficient contact time is permitted to dissipate the heat, which is available in the extruded plastic. Machinery Center carriers a wide variety of Extrusion Sheet Lines from some of the top manufacturers like Cincinnati-Milacron, Davis Standard, Welex and Mitsubishi.
