Introduction to Plastic Molding Processing Technology

Small, thin, and lightweight! Challenging the production of a mobile antenna using a plastic molded composite integrated design!

This is an introduction to a case where "hot melt molding technology" was adopted to achieve the miniaturization of portable antennas for PCs equipped with digital TV tuners. To miniaturize the antenna, it was essential to fold the antenna in half. To achieve this, it was necessary to mold it as a single unit, including the hinge. What made this possible was a method using hot melt resin that can be molded at ultra-low pressure, which is still not widely used in Japan. By combining three types of molding technologies—gas assist, carbon dioxide, and hot melt—we successfully shaped a folded antenna through integrated molding without using a single screw. 【Benefits of Implementation】 ■ Reduction of subsequent processes through integrated molding ■ Good results in environmental testing (thermal shock testing machine) *For more details, please refer to the catalog or feel free to contact us.
