R&R Plasticast® was developed for the investing and burnout of commonly used plastic or wax/plastic pattern materials. Ideal for resin models created in rapid prototype processes and printers. The high expansion of all these pattern materials requires an equally high expanding, extra high strength investment. Plasticast® provides a smoother, cleaner casting surface not obtainable with standard brands of investment and was also designed for easy removal in water. Plasticast® also provides a superior casting surface when standard injection waxes are used. Supplied in convenient easy to carry 44lb bliss box. Made in USA
