Technology Overview

As bonding methods for integrating metal and resin, a bonding with adhesive and mechanical bonding with screwing are widely used. However, in recent years, new bonding methods have been required due to problems with VOC regulations, restrictions on design freedom, and person-hours. For example, there are insert molding and outsert molding as methods for integrating metal and resin using resin injection molding. In these methods, a metal is generally molded so as to be wrapped in a resin, and the shrinking property of the resin is used for bonding. In these cases, since there is some space at the interface between the metal and resin, it cannot be applied to products that require airtightness. In addition, surface bonding of metal and resin is not possible. By providing a shape that makes it easy to bond with resin on the metal surface, PAL-fit® realizes solid and uniform surface bonding and exhibits excellent bonding strength and airtightness.
