Extruder – TWIN SCREW EXTRUDER | Jatchen
Twin screw extruder consists mainly of drive system, feeding device, barrel, two intermeshing screws, die head and control system. During operation, premixed powder coating raw materials enter the barrel via the feeder. Driven by the rotating screws, materials move along the screw grooves toward the die head. Meanwhile, external heaters melt the materials, and screw rotation generates shear force to knead them, fully dispersing and mixing components like resins, curing agents, pigments, fillers and additives. Finally, the uniformly molten mixture is extruded through the die head, providing qualified semi-finished products for subsequent tableting and crushing.
