Abstract
An injection molded insert having a field of integrally formed hooks on a surface can be used as a component of a molded article, such that the field of hooks will be on a surface of the molded article. The molded article having the mold insert as a component can be formed by various molding processes such as injection molding, compression molding, blow molding or rotational molding, or by forming from a moldable mass such as sprayable resins, epoxy-based resins, or fiberglass-based resins.
