ABSTRACT:
A locating and fastening protrusion extending from a back surface of a vehicle trim strip or molding strip being integrally formed with thermoplastic material of the molding strip. The protrusion is formed by applying a hollow heated die cavity against the thermoplastic back surface of the molding strip. The heated die cavity causes the thermoplastic material to melt and as the die cavity is applied against the molding member, the melted thermoplastic material is forced into the die cavity. The die cavity is then cooled such that the material within the die cavity solidifies. The die cavity is removed such that an integral protrusion is left extending from the molding member.
