A pelletizing extrusion die comprising a die body contains a plurality of extrusion holes. Each of the extrusion holes is defined by a defining surface of the die body wherein at least a portion of the defining surface has a low-friction coating deposited thereon. A method for applying the low-friction coating to the defining surface wherein the applying step occurs at a temperature equal to less than about 520° C.
