In case of COLLIN strand lines, it is unique that all production steps are provided by a single source – compounding, coextrusion, take-off and cut.
The vertical water bath is the highlight – a COLLIN innovation, which guarantees reliable roundness.
For an exact throughput of the line, the extruders are equipped with melt pumps and pressure/speed controls. By using a multi-layer die, the strand is directly and vertically extruded into a water bath. This process eliminates any influence of a calibration system. The gravitation guarantees high accuracy of diameter and roundness.
Moreover, a continuous water flow guarantees an absolutely calm water surface when the product enters the cooling tank.
