Latest Patents

Hirai's latest patents include an innovative automobile windshield molding and a method of producing the same. This windshield molding is designed to be installed in the space between a windshield and the periphery of a window opening of a vehicle body panel. The molding consists of a pair of extruded side molding parts, corner molding parts, and an upper molding part that is integral with and extends between the side and corner molding parts. Notably, the side molding parts are thicker than the upper and corner molding parts, which allows for the formation of a water drain channel.

Another significant patent is for an extrusion molding apparatus and a method for controlling it. This invention aims to shorten cycle time by enabling a robot to operate at high speeds, regardless of the shape of the moldings. The apparatus includes an extrusion molding machine that delivers material to create frame-shaped moldings through a nozzle. A robot holds the workpiece, adjusting its working speed to ensure that the travel speed of the workpiece's rectilinear portions is higher than that of the corner portions, thus allowing for flexibility in the molding process.
