Bonding Method
Injection molding
A method of bonding resin and surface-treated aluminum for bonding is employed at the same time as injection molding of the resin.
Thermocompression bonding
Only the resin at the aluminum-resin interface is melted by heat conduction from the aluminum, and a load is applied to bond the aluminum and resin.
