Reduction of the number of parts and improvement of waterproofing through composite integral molding of glass and metal inserts.
Glass, metal, and resin in one process. We completely reduce assembly and subsequent processes with composite insert molding.
In electronic devices, medical equipment, and automotive components, when integrating glass panels with metal frames, traditional methods required subsequent processes such as adhesion, fitting, and screw fastening, leading to increased component count, reduced waterproof reliability, and rising costs. Yoshida Techno Works' glass-metal composite insert molding technology simultaneously inserts glass and metal terminals or frames into the same mold and encapsulates them with resin. We implement measures against residual stress caused by the difference in linear expansion coefficients of glass, metal, and resin from the mold design stage, providing stable quality integrated molded products. Please also consult us regarding waterproof performance and our comprehensive air leak inspection system.
