Polycarbonate chocolate molds are considered to be the best molds for making chocolates and other confections. They are known for their superior durability and ability to withstand heat. The finished products demold easily and have a high quality finish. In addition, most polycarbonate molds work well with other confectionery equipment.
Polycarbonate is a type of plastic. Confectionery molds are made from a special type of polycarbonate that is FDA approved for contact with food. It can be made into a mold by thermoforming or plastic injection. Thermoforming involves heating a plastic sheet and forming it around an object using vacuum suction. Plastic injection is a process whereby a plastic resin is formed around a metal master under high pressure. Plastic injection is by far the best method, but is also much more expensive and time consuming. Most polycarbonate chocolate molds are manufactured in Europe; however, some are made in the United States. Companies such as Micelli Chocolate Mold Co. and Tomric Plastics are two companies in the United States that specialize in making polycarbonate chocolate molds.
If you plan on using chocolate molds for a commercial purpose or for a long production run, you should seriously consider buying polycarbonate chocolate molds. They are more expensive than hobby grade molds, but they will last much longer and yield a higher quality finished product.
