Inventor: HOSHI CHUICHI
IPC: B29C48/53
Filed: 2000-05-26
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption due to transfer power and a heater by shortening the effective length of a screw while ensuring the conventional production quantity of a resin and to correspond to the production of a resin of every kind even by a single screw by enhancing the transfer efficiency, heat efficiency and kneading efficiency of a resin while shortening the time required in the color change of a resin or the like.
