WiPa Plast Compactor is an agglomerator for gentle densification of plastics with low bulk density
WiPa Plast Compactor is mainly used to increase the bulk density of plastic materials in various forms like fibres, films, foamed materials, powders and even fine particles. Nevertheless, there are several other fields of application. For example, efficient drying of plastics being processed in a washing line. During the process the material gets heated, moisture evaporates, so that final humidity content is reduced up to less than 0,5%. In this condition the material is prepared for further processing in an extruder or an injection moulding machine. Additives and fillers like color pigments, plasticizers, etc. can be fed via special dosing units directly into the feeding screw of the Plast Compactor. The material is being warmed in the compacting zone until the fillers have been absorbed. Crystallization of PET flakes after a hot washing process is also a possible task for the WiPa Plast Compactor. The material gets warmed till it reaches a pasty condition what aligns the molecules.
