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.
Claims10
A method of cold casting a composite product, comprising the steps of:
- i. mixing a curable resin with metal particles to form a composite mixture, wherein the curable resin is selected to have a cure time and viscosity that allows the metal particles to fall to the bottom of the mold to appear on the face of the composite product;
- ii. pouring the composite mixture into a mold made of a machinable and recyclable substrate;
- iii. causing the metal particles to fall to the bottom of the mold to appear on the face of the composite product through the selection of curable resin and metal particles;
- and
- iv. curing the composite mixture in a pressurized chamber for a time sufficient to eliminate the appearance of bubbles in the cured composite mixture;
- wherein the chamber is pressurized to between about 40 and about 70 psi.
