Cartridge DispensingRapid prototyping is neat, fast and cost-effective with cartridge-dispensed polyurethanes. Low viscosity systems formulated with 1:1 and 2:1 mix ratios are particularly well suited for easy cartridge filling as well as mixing, dispensing and application from disposable static mix nozzles. Hand and Mass CastingEasy-to-mix Shore A and Shore D hardness polyurethane resin systems are widely used for hand pouring and mass casting to produce thin-walled prototypes as well as parts up to four inches thick. Machine DispensingRapid casting polyurethanes that gel in less than 60 seconds at room temperature are formulated for automated meter/mix dispensing equipment that quickly injects materials into the mold. Pressure CastingTo ensure complete mold filling for thin-walled and other difficult to inject parts, mixed polyurethane resin and hardener are de-aerated, poured into a mold and then cured in a pressure pot. RotomoldingRotational molding or rotocasting is an economical method for producing hollow parts. Thermosetting polyurethanes are ideal for rotomolding rigid “shells” used for seating, fluid containers and theme park display fascia. Vacuum Assisted CastingPolyurethanes are often injected into a mold under a vacuum to eliminate voids for applications such as medical equipment prototypes, medical training models, clear lenses, furniture and automotive components. |
