Abstract

An efficient process for producing resin composition pellets such as fiber-reinforced LCP or PPS pellets, wherein break of a resin flow is prevented and dispersion of discharge amount is suppressed. The process includes extrusion of a resin composition through nozzles of an extruder via a die holder of the extruder after the composition has been melted and kneaded, wherein the extruder has the die holder disposed at the head of a extruder barrel and a die plate having a plurality of nozzles disposed at the exit of the die holder; the resin composition comprises a thermoplastic resin (A) having a melt viscosity of 50-5,000 poise and a reinforcing fibber (B) having a length of 0.05-5mm; the extruder is a twin screw extruder; and the outer diameter (K) of the screw, the distance (L) between the exit of the nozzles and the end on the extruder barrel side of the die holder which is connected to the extruder barrel, and the extension angle (θ) of a passage inside the die holder satisfy the following relations L ≤ 2K and 0 DEG ≤ θ ≤ 15 DEG.
