Ransom & Randolph® Plasticast® Investment, 19.96 kg.

Ideal for investing plastics and the resin models created in rapid prototype processes, this Plasticast® investment from Ransom & Randolph® withstands the pressure involved in the burnout of these materials. Plastics and resin expand greatly as they melt in the burnout process; this expansion puts tremendous pressure on the surrounding investment. The strength of this investment ensures that your patterns remain true through the burnout process. Use this investment as you would any traditional gold and silver investments.
