INTERNAL MECHANISM PART OF OFFICE MACHINERY OBTAINED BY MOLDING AMORPHOUS RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for improving the dimensional accuracy and dimensional stability of the internal mechanism part of a copier, a printer, a facsimile or the like requiring the dimensional stability of a product and the dimensional accuracy of a molded article without being restricted by a resin composition and a product design and holding the productivity thereof and to enable the product planning of the internal mechanism part of new office machinery. SOLUTION: Carbon dioxide is dissolved or infiltrated in a resin composition in an amount of 0.2 wt.% or more and this carbon dioxide-containing resin composition is molded in a mold cavity to obtain the internal mechanism part of the office machinery.
