The Corex Process
Checking for contaminants is the first step of the recycle process. This includes lab testing, visual spot checks and often pre-shredding the material before attaching the material to a forklift and tipping into the main shredder.
Once shredded, the material follows a belt system that passes a metal detector.
Detect And Shred
Heat And Melt
Material continues along the belt towards the furnace if it successfully passes the metal detector. Once in, the material heats up towards it’s melting point before moving to a screw that pushes the material to its final stages.
The Filter is the final measure to make sure the material comes out as expected. Any remaining contaminants such as PET or Paper would be caught due to the different material properties of other plastics.
Once pushed pass the filter at a large pressure, the material will flow towards the end of the machine and extruded like spaghetti at a very high temperature. This is where the cutter cuts the extruded spaghetti at a high RPM for the plastics to be made into small pallets.
Those pallets are then cooled in a water bath to form the bead shape and delivered into a blower that would blow the pallets into a bag for Corex Plastics' Rebound and Encore products.
