Doc Robinson's Super Fast Platinum Casting Investment is a professional-grade, two-part powder and binder system developed by Mark Robinson from a dental investment formula. Designed for speed and versatility, it supports casting in platinum, palladium, gold, silver, brass, copper, and other similar metals. The entire turnaround from wax to finished casting is less than four hours, with a burn-out time as short as 2½ hours — making it an ideal solution for jewelers who need to quickly cast one or two rings in any precious metal.
This investment sets hard quickly, requires a mixer for preparation, and delivers a satisfactory surface finish. Complete instructions are included with each box of investment. Additional binder solution is available separately for ongoing use.
Shipping Restriction: This product ships via UPS Ground or FedEx Ground only.
