Abstract
A composite article such as an automotive trim strip comprising a thermoplastic shell secured to the front of a supporting member. An icon is embedded in a recess in the front of the shell so that the front of the icon is substantially flush with the front of the shell. The icon is secured in the recess of the shell by an adhesive. The supporting member is made of a hot melt material and is bonded to the shell in an injection mold. The heat of the molding operation softens the thermoplastic shell sufficiently to cause the icon to form a recess in the shell and become embedded therein. The heat of the molding operation also cures the adhesive bonding the icon to the shell.
Claims2
A method of making a composite automotive trim strip composed of a supporting member, a thermoplastic shell for covering at least a portion of the supporting member and having a front and a back, and a metallic icon having a front and a back, comprising:
- providing the icon and the shell,
- applying spaced-apart globs of a heat-curable adhesive to the back of the icon and adhering the back of the icon to the front of the shell,
- providing a mold having a mold cavity formed with a mold surface shaped to receive the shell,
- placing the shell and adhered icon in the mold cavity in position with the front of the shell and the front of the icon opposed to the mold surface, and
- introducing into the mold cavity a flowable hot melt material which is compatible with the material of the shell to form the supporting member and, at the same time, by the heat of the hot melt material
- (a) bonding the shell to the supporting member,
- (b) softening the shell enough to cause the icon to form a recess in the shell and the icon to become fully embedded in the recess with the front of the icon flush with the front of the shell, and
- (c) curing the adhesive to form a strong bond between the back of the icon and the recess in the shell.
