Abstract: A method of forming a stamped metal laminate part from a strip stock with a layer of viscoelastic material laminated between two metal layers, and a laminated abutment clip made by the method. Part carriers are disposed on the sides of the stock. A longitudinal axis extends between the part carriers through the stock. The stock is advanced through a progressive die to a first position where a first form is created, a second position, where a second form is created by modifying the first form, and to a third position where a third form is created. Relative sliding of the metal layers in the stock is prevented between the axis and the form being created, and relative sliding of the metal layers is permitted at a section beyond the particular form being created, preventing delamination of the stock while the first, second and third forms are formed.
