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. You can view the test details by downloading the PDF, so please feel free to take a look. [Contents Included] - Concept of dual insert molding line - Evaluation tests for "Adhesion Improvement" technology - Pursuit of "Adhesion Improvement" technology - Towards the establishment of "Adhesion Improvement" technology - Investigating causes and extracting issues for "Establishment" *For more details, please refer to the PDF document or feel free to contact us.

Fuji Seiko Co., Ltd. stands on the customer's side, understanding product functions and conducting proposal-based sales from the development stage. We provide a consistent process from design to prototyping to mass production, offering rationalization proposals with an eye on final mass production. If we receive drawings at the conceptual stage, we can consider the feasibility of the product and provide technical proposals, which is one of our strengths. Our company manufactures press molds, performs press processing, and conducts molding processing in-house. Utilizing our press technology, we offer proposals that find benefits in quality, cost, and delivery through a continuous insert hoop molding line. 【Development Proposal Examples】 ■ Want to integrate multiple components ■ Want to convert machined parts to pressed parts ■ Want to apply spring processing on both sides of molded parts ■ Want to embed terminal cut surfaces within molded parts ⇒ Solving designers' concerns ⇒ Bold design changes incorporating VE/VA are possible! For more details, please refer to our catalog or feel free to contact us.

"Continuous Hoop Insert Molding" is a high-precision advanced technology developed by Fuji Seiko Co., Ltd., which completes the entire process inline from metal material → primary molding → cutting/bending → secondary molding → product cutting, and even inspection. By utilizing double hoop molding, it is possible to arbitrarily combine different colors/types of resins, enabling unmanned production of multi-color and multi-resin molding that has never been possible before. [Comparison with Conventional Production Methods] ■ Conventional Method: "Manual labor" carries the risk of terminal arrangement errors. ⇒ Our Method: Arrangement errors "0" → Quality improvement ■ Conventional Method: "Robots" require specialized equipment, leading to high initial investment. ⇒ Our Method: Can be handled with general-purpose equipment → Reduced initial investment For more details, please refer to the catalog or feel free to contact us.
