Rubber melt pump is mainly used for high temperature and high viscosity polymer melt delivery, pressurization, metering. Its main function is to pressurize and stabilize the hot melt from the extruder, keeping the melt flow accurately and steadily into the extruder head. Today, the melt gear pump has been widely used in chemical fiber, granulation, plastic film, sheet, sheet, profiles, pipe, wire and cable, drawing, composite extrusion and other production lines, Machinable materials cover most
