Abstract

PURPOSE:To equalize the dispersion of a crosslinking agent into a resin by forming the flight pitch of a supplying zone in an extruding machine smaller than that of a compressing zone or a weighing zone. CONSTITUTION:The pitch of a flight 8 in a supplying zone 10 is formed smaller than that of the flight 8 in a compressing zone 11 or a weighing zone 12, such as less than 1/2, thereby increasing the staying time of a resin material 5 and a crosslinking agent 14 in the zone 10. Accordingly, the dispersion of the agent 14 into the material 5 becomes uniform, and even if the rotation of a screw 4 is raised to increase the extruding amount, a crosslinking molding material having preferable dispersion of the agent can be obtained.
