Title:
ポリエーテルイミド樹脂製の眼鏡フレームの製造方法
Document Type and Number:
Japanese Patent JP2011501247
Kind Code:
A
Abstract:
Disclosed is a method of manufacturing a glasses frame using a polyetherimide resin, through injection molding and cutting, in order to realize excellent properties of the polyetherimide resin. The method of manufacturing a glasses frame made of a polyetherimide resin includes subjecting a polyetherimide resin to injection molding, thus producing a preformed sheet, inputting designs for various glasses models to the preformed sheet, cutting the preformed sheet into the glasses frame according to the input design through laser cutting or CNC cutting, forming lens grooves and hinge grooves in the cut glasses frame, subjecting the rough surface of the glasses frame, having the grooves, to surface treatment through tumbling or polishing, and subjecting the glasses frame, having been subjected to surface treatment, to thermal molding and then to pressing using a mold, thus forming the shape of glasses, and attaching hinges to the formed glasses frame.
