Sealing with insert molding! Improving adhesion between metal and resin.

A must-see for development personnel aiming for efficiency! Achieving high adhesion and airtightness by using special elastomers.

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.
