Over the years, WP has evolved and strengthened its customer-oriented focus to include a precision machine shop staffed with skilled tool makers and an engineering staff capable of evolving a sketch into a finished part.

We employ state-of-the-art technologies like 3D printing that permit designs to be quickly evaluated in production-like materials before cutting a mold. In addition, we are capable of performing Finite Element Analysis & Mold Flow Analysis which can be a critical step in the manufacturing process to mitigate risk both technologically and financially.
