Hot-melt extruder principle
l Hot-melt extruder technology ： Two or more of the samples were placed in a temperature controlled barrel，together heated to a molten state.Under the action of the screw, the samples were cut, mix, and finally through a die under a certain pressure，become dispersed uniformly shaped product
l Hot-melt extruder basic idea：Place multiple segments threaded element within different functions in the axial space.So that multiple samples size decreases, and mutual penetration and exchange，eventually achieve molecular level mixing。
