Candy Making Molds

Looking to make candy molds and I wonder how. Is there some plastics that I should use? It is readily available at the customers? What materials should I use to make the original sculpture that will be based on the mold? When making candy, how do I prepare for molds?

All links would be appreciated.

Some candy manufacturers use large quantities of sugar, placed in shallow containers, then press the stamp or forms in sugar. Pour the mixture into molds and let cool. The sugar can be reused several times. insofar as the forms are concerned, your imagination is the limit.
