Cooling in plastics processing

In many extrusion processes, the effectively achievable output is below the maximum extruder output. The extrusion line could therefore produce more, but the product quality deteriorates at higher throughputs. In many cases, this has to do with the fact that the plastic melt becomes too hot due to friction and limited cooling devices. Promix cooling mixers and melt coolers are a simple and cost-effective retrofit solution. The melt temperature can be homogenized and lowered as required, regardless of the throughput.
