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.
The touch screen control system is ergonomically designed and files all process as well as quality parameters.
