Extruder Line for Polyamide Thermal Break Strips | POLYWELL

An extruder line, also known as an extrusion line, refers to the complete, integrated set of equipment required to continuously manufacture a plastic product from raw material to a finished, packaged state. It is a synchronized system where each component plays a specific and critical role. The line begins with upstream equipment: material storage, drying systems, and conveying units that feed the plastic resin into the extruder. The extruder itself, the heart of the line, plasticizes and pumps the material. The molten polymer then passes through a die, which gives it its shape. Immediately downstream, the shaped extrudate enters the calibration and cooling stages, where its dimensions are fixed and it is solidified. A haul-off unit then provides the pulling force to draw the product through the line. The process concludes with a finishing station, which could be a flying saw for cutting profiles to length, a winder for coiling flexible products, or a stacker for sheets. All these components are controlled by a central system that ensures synchronization, particularly between the extruder's output rate and the haul-off's pull speed. The overall performance, efficiency, and product quality are dependent on the seamless integration and stable operation of the entire extruder line as a single, cohesive unit.
