The excellent technology of Fujiseiko, which continuously creates products that symbolize the next generation, not only satisfies customer needs but also aims for an even higher level.

This document contains information on "Technologies for Improving Adhesion between Metal and Resin." In insert molded products, the interface between metal and resin is not well adhered, leading to issues such as water ingress due to high-pressure washing and condensation in the vehicle's engine compartment. Therefore, our company is conducting evaluation tests with the goal of preventing air leakage by improving the adhesion between metal and resin. [Contents] ■ Concept of a double insert molding line ■ Evaluation tests of "Adhesion Improvement" technology ■ Pursuit of "Adhesion Improvement" technology ■ Towards the establishment of "Adhesion Improvement" technology ■ Investigating causes and extracting issues towards "Establishment" *For more details, please refer to the PDF document or feel free to contact us.

This document contains information on "Technology for Improving Adhesion Between Metal and Resin." In insert molded products, the interface between metal and resin is not well adhered, leading to issues such as water ingress due to high pressure during car washes and condensation in the vehicle's engine compartment. To address this, our company improves the adhesion between metal and resin through the following dual molding process: - Using elastomer (a special material rich in adhesion) in the primary molding - Joining metal and resin through heat and thermal treatment in the secondary molding We conduct air leak evaluation tests.
