Abstract: Method of cold casting a composite product which includes the steps of making a composite mixture comprising a curable resin and metal particles, pouring the composite mixture into a mold made of a machinable and recyclable substrate; and curing the composite mixture in a pressurized chamber for a time sufficient to eliminate the appearance of bubbles in the cured composite mixture. The curable resin is selected to have a cure time and a viscosity that allows the metal particles to fall to the bottom of the mold to appear on the face of the composite product. The finished product can resemble traditional foundry cast metal products while employing a much lower amount of metal to achieve cost savings.

Abstract: Method of cold casting a composite product, a pressure curing apparatus for use in curing a composite mixture under pressure, and use of the pressure curing apparatus in the present method. The method of cold casting a composite product includes the step of curing a composite resin mixture under pressure to eliminate the appearance of bubbles in the composite product. The pressure curing apparatus comprises, amongst other things, a pressure chamber that is sized and shaped to conform with the size and shape of a mold inserted therein to minimize wasted space and reduce the amount of energy required to pressurize the chamber.
