screen pack/mesh pack/mesh screen/exruder screen is a very important part of the extruder. Only qualified products can be produced through filtering. Extruder filter is used for filtering and blending processing in the production of various viscous materials and products such as plastic, chemical fiber, rubber, hot melt adhesives, adhesives, coating materials, mixtures, etc. The extruder filter has mesh type With mesh belt type, the extruder can change the filter without interrupting production through automatic screen changer, saving labor and time, stable product performance, realizing automatic screen change without operation, increasing effective filtering time, and reducing production costs.
