A Family Owned Machining Facility

Rock Valley Tool, LLC is a family owned machining facility located in Easthampton, Massachusetts. The company was founded in the late 1950’s by William Ploran Sr. Bill and his son ran the company primarily servicing the plastic extrusion blow-molding industry. Since his departure, Rock Valley Tool has expanded into several other industries including, but not limited to commercial/industrial, medical, firearms, aerospace; all while continuing to serve several customers in the plastics industry. The company is now owned by Elizabeth and Jason Paquette. Jason has been a proud employee of Rock valley Tool since 2000, and when the chance arose for him and his partner to purchase the company, they jumped at the opportunity. In December 2013, they made it official, and acquired Rock Valley Tool, LLC.
