Conical polyurethane plugs are open cast in high volume with rapid tooling startup. Plan Tech’s state of the art machine shop is capable of making what we like to call master patterns for conical polyurethane plugs. After we machine one master pattern we can cast hundreds of urethane molds to produce thousands of conical polyurethane plugs each year of all different sizes and hardnesses.
Plan Tech has been specializing in custom urethane applications for 30+ years with conical polyurethane plugs being one of our biggest demands. Currently, we cast several different sizes including some for bolt-on applications with a molded bolt or mounting plate. Some of the more basic polyurethane plugs are just different colors for an assembly manufacturer as they use the different colored conical polyurethane plugs to mark different size gears. That company relays that each plug will be within tolerance to ensure the correct gear selection during assembly.
Plan Tech also has a variety of additives for our polyurethane to enhance different physical properties. Our most common additive will add lubricity to the urethane material as it wears. This will keep the polyurethane coating clean and will resist sticking to the material. Custom cores can be fabricated at Plan Tech or supplied by the customer for high strength applications or bolt on conical polyurethane plugs.
Waterjet cut urethane parts are just one of the many cast urethane services that Plan Tech provides. We utilize a “state of the art” Flow Water jet 4′ x 8′ Integrated Flying Bridge waterjet cutting machine. The dynamic head virtually eliminates the taper normally associated with WaterJet cut urethane parts while improving cutting speeds, part accuracy and tolerances in cutting flat stock materials. There are so many possibilities; Cast urethanes with fabric reinforcement, bonded metallic layers or UHMW. Waterjet cut urethane parts can make quick work of the dissimilar materials that make conventional machining difficult if not impossible. For example, rigid soft durometers with reduced elongation and greater tensile strengths or metallic parts with integrated vibration damping or high rebound properties. Waterjet cut urethane parts are not the only way to cut urethanes, but it is the best way that we have found!
