Plastic extrusion dies - The die material influences the melt flow behaviour
Surface roughness of extrudates is an economic problem in the extrusion of various polymers. It limits the output rate of the extrusion line. The flow properties and melt fracture properties of a polymer can be selectively influenced by suitable choice of die materials.
