POLYACETAL RESIN MOLDING AND PRECISION MECHANISM COMPONENT

摘要

PROBLEM TO BE SOLVED: To obtain a polyacetal resin molding that is superior in slidability, dimensional accuracy and durability, facilitates the dimensional control of a molded article, and has excellent dimensional stability.SOLUTION: A polyacetal resin molding contains a polyacetal resin composition including: a polyacetal resin (A); a compound (B) in which a difference &Dgr;V((V)-(V)) between a specific volume (V) at 50°C and a specific volume (V) at 90°C is 0.05 cm/g or more; and a crystal nucleating agent (C) with a particle diameter of 0.5-100 μm.
