ROOF RAIL, ITS PRODUCTION METHOD AND MOLD

摘要

PROBLEM TO BE SOLVED: To obtain excellent appearance and high grade as a whole by improving an outside surface state and to produce an uncoated product. SOLUTION: In a roof rail of the integrated molding of a polyamide resin composition containing a polyamide 210 deg.C or below in crystallization temperature and 70 deg.C or below in glass transition temperature and glass fibers, the difference between the maximum and minimum of surface gloss at 60 deg.C is 5% or below, and the difference between the maximum and minimum of surface roughness is 0.5μm or less.
