4 Classification of bonding strength between metal and plastic

Characterizing the bonding strength of metal and plastic can be divided into.

a) Butt strength of metal and plastic after bonding;

b) Tensile shear strength after bonding between metal and plastic;

c) Peel strength after bonding between metal and plastic;

d) Impact peel strength after metal and plastic bonding;

e) Sealing performance after metal and plastic bonding.
