The invention provides a pre-impregnation side feeding device and method. The device includes an extruder main body with a main barrel for material mixing, melting, conveying and extrusion, a material guiding unit and a side feeding unit. The material guiding unit draws molten materials from the main barrel and transports them to the side feeding unit. Powders, glass fibers and other high-fraction additives are pre-impregnated and mixed with molten materials in the side feeding chamber before being fed into the main barrel. The structure reduces compression and shear damage to side-fed materials, accelerates moisture discharge through exhaust ports, improves mixing uniformity, and effectively solves common side feeding defects to enhance product quality.
