Abstract

PURPOSE: To provide a molded article having a uniform wall thickness by a method wherein a disc or umbrella shaped double-layer rotary feed plate formed having a slit is arranged in a rotary metal mold and molded material is fed while the plate is moved up and down inside the mold.
CONSTITUTION: A pulverized resin such as polyethylene is fed into a hopper 7, fed to a feed portion (which is arranged in a rotary metal mold 1 heated from outside) through a feed pipe 6 at a constant flow rate by a blast created by a blower 8 or the like, and allowed to fall to the central portion of a slit 5 of a double disc 3-4. With the disc 3-4 rotated at high speed, the resin is discharged radially from the central portion of the slit 5 toward the inside wall of the mold 1. The resin applied to the inside wall of the mold 1 is melted, and coated onto the wall in a uniform thickness by the vertical movement of the disc 3-4. Then, heating of the mold 1 is stopped to gradually cool the mold, obtaining a molded article with a uniform wall thickness at every part.
