Principle and Advantage of Hot Melt Adhesive Extruder

　　Hot Melt Adhesive Workflow

　　Granular or powdered polyphthalamine/polyvinegar material is filled in the extruder, and the air mixed in the material is extruded backward while the extruder screw extrudes the rubber. The real energy of the extruder comes from the heat generated when the screw of the extruder rotates, not from the heater, which is only used for preheating when the extruder is turned on or off. Therefore, the residence time of the compound at working temperature is extremely short, because only the hot melt glue needed for the next few minutes is melted.
