WPC granulating line is used for compounding wood plastic composite materials with good degassing and color mixing for WPC profiles production » . The granulating extruder works by melting the plastic and mixing it with the wood flour and other additives, then extruding the mixture through a die to create the granules as traditional granulating way. But it is proven that the compounded WPC materials have good performance also from the exttruder head without pellet mold, And it's an efficient way to get higher output from the same WPC granulating line, which are developed by MG technician team in 2011. It's the popular granulating way for all PE WPC or PP WPC in the whole WPC industry after that time.
