The extrusion process lends itself to many, diverse applications utilizing a broad range of materials. Useful for bulk or continuous production, extruders create objects of fixed cross-sectional profile, either simple or complex, that can be rolled, cut or pelletized to meet customer requirements. Since input materials or ingredients are mixed and formed using only compression and shear forces, brittle or difficult materials are easily handled and processed into finished products. Die and cutter design are critical for quality final results, shaping the material into required profiles, allowing for its behavior and flow under specific conditions, whilst imparting surface characteristics and finishes.
