An introduction to improving the dyeing and whitening process around the joints of aluminum-plastic

The design of this scheme solves the problem of dyeing and whitening after the anode of the aluminum-plastic assembly from two aspects.

Measure the holes that the resin can penetrate during injection molding with a size of about 20~100nm, which produces an anchor bolt effect, improves the degree of bonding between metal and plastic, and reduces the migration of plastic components caused by poor injection molding. The second is to dye after anode Before treatment with RTsAN8010, the plastic components migrated to the surface of the aluminum material around the joint seam during the injection molding process were removed.
