Williamston Products, Incorporated (WPI) is a leading supplier of innovative interior trim components in the North American auto industry. Even though WPI has been a name only since April 2007, the business and plants have been manufacturing many of these same products for over 30 years (established in 1977). Our product lines are manufactured with a vast array of processes and technologies ranging from blow molding, injection molding, vacuum and thermo forming, laminating, and cut and sew among many others. The owners of WPI have over 70 years combined experience in the auto industry. This experience, coupled with a work force and plants in existence since 1977, can deliver the quality, technology, timing and affordability that is required ever so strongly by OEM’s and tier one suppliers. We welcome you to our website and hope it will introduce you to WPI.
