摘要:
A shaping roll for melt extrusion molding used for melt extrusion molding of thermoplastic resin, the shaping roll for melt extrusion molding comprises a metal roll body, a first cylinder, and a second cylinder. The metal roll body has a heat medium passage internally. The first cylinder covers a surface of a middle portion of the roll body part. The second cylinder covers surfaces of both end portions of the roll body part. The first cylinder comprises a first metal material having a thermal conductivity of 40 W/m·K or more. The second cylinder comprises a second metal material having a thermal conductivity of 20 W/m·K or less. The first cylinder and the second cylinder are at least partially joined to each other.
