RESIN MOLDING MACHINE AND MEMBER HAVING PASSIVE STATE FILM

摘要

PROBLEM TO BE SOLVED: To drastically-improve a yield by eliminating foreign substances caused by the degradation of a molten resin to be mixed into a molding. SOLUTION: A resin molding machine is composed of a member for the resin molding machine which has a surface contacted with the molten resin and in which at least part of the contact surface is covered with a matrix material or the oxidized film of a component of a part contained in the matrix material. By doing molding with the use of the member, the mixing of the foreign substances associated with the degradation of the molten resin into the molding can be prevented. COPYRIGHT: (C)2004,JPO&NCIPI
