The Ransom & Randolph Plasticast PT investment & binder system was developed and is ideally suited for, the investing and burnout of commonly used plastic or wax/plastic pattern materials. The high expansion of these pattern materials requires an equally high expanding, extra high strength investment. The Plasticast PT investment & binder system provides jewelry casters with a mold material that meets those demands while maintaining mold surface and dimensional integrity for high-temperature metal casting. The Plasticast PT investment & binder system can also be used with standard wax patterns for high-temperature metal casting.
