Delaware Metals machines exotic plastics and metals to our customer’s specifications. We can handle a variety of materials that other machine shops do not work with due to their properties, machinability and/or cost. One such exotic plastic we frequently machine is Rulon J. Rulon plastics are known for their low coefficient of friction, excellent abrasion resistance, wide range of operating temperatures, and chemical inertness. Common applications for Rulon include seals, piston rings, bearings, and electrical insulation. We machine a lot of bushings out of Rulon J due to its properties, these being for a high-speed gearbox application. If you are having troubles finding the best materials for your project, give us a call. We have the knowledge to help you pick the right material, and the technology/skill to machine it.
