Small metal particles in the melting process of plastics often lead to costly breakdowns of injection molding machines, extruders and blow molders. The amount of such metal contaminants increases during the processing of regranulate and shredded raw materials. As a result, clogging of nozzles, filters and hot runner systems can lead to production downtime and delivery delays. The PROTECTOR metal separator is installed directly above the feeder of an injection molding machine, extruder or blow molding machine. It detects all magnetic and non-magnetic metal contaminants (steel, stainless steel, aluminum, etc.) – even if they are contained in the product. The metal contaminants are ejected through the Quick-Flap separation unit.
