Posi-Melt “MB-XLA” Barrier/Mixer Screw
Our proprietary “MB” barrier forces the polymer between the barrier flight and the barrel ID for added extensional strain to assure complete melting. We can couple the “XLA” mixer to the Barrier for processing a variety of resin groups including PP, HDPE, LDPE, PS, PET, ABS and other groups delivering the Highest Outputs and Homogenization available. All Posi-Melt screws are designed to have an adequate feed depth to promote solids conveying to build pressure for moving the polymer through the transition and metering zones. Additional care is taken to design-in the proper leading and trailing edge radii to avoid low velocity sections in the channel and to maximize the pressure. The benefits of our design are; Color and Material change times are reduced compared to our competition because these is no need for Two separate channels to achieve thorough melting and good dispersion…our channel is 100%pressurized throughout for Solids Conveying, Melting and Pumping.
