Lost-Wax Casting Overview

Lost-Wax Casting is the method by which an identical duplicate metal piece is cast from the original. The technique is commonly used in casting bronze, gold, and silver pieces. It is a simple and economical way to create items of any shape. By using a mold to construct identical items from different metals, Lost-Wax Casting offers several advantages over other methods of metal casting. This method can achieve complex intricate works effortlessly.

 

a thin layer of wax is applied to the molds to make them solid

The technique is simple enough and can be accomplished by hand with the help of a few instruments. To begin the casting process, a thin layer of wax is applied to the molds to make them solid. It is important to use a small amount of wax for this process to obtain the best results. Small amounts of wax are also required to clean and harden the final copy.

 

the mold is prepared and the metal pieces are melted

The cast bronze item is moved into place and once cooled, it is trimmed from its shape to obtain a smooth surface. Once the item is smooth and free of bumps, it is polished and prepared for polishing. After polishing, the piece is ready to be further molded by hand or machine.

If you want to cast bronze items or other objects in Lost-Wax Casting, you must purchase a crier. These criers have to be specifically made for Lost-Wax Casting to avoid damage to the casting or your finished product.

follow the instructions that come with your crier

If you want to have Lost-Wax Casting performed on your bronze sculptures or other metal items, you need to follow the instructions that come with your crier. The crier will instruct you on how to load the molten bronze into the mold and also on the cooling down period after the casting process. If the metal has been prepared before the casting process, the crier can instruct you on how to remove the excess wax from the metal. Some Lost-Wax Casting kits contain special cleaners that can be used to clean the metal if you do not have the time to make use of the special cleaners available with the kit.

 

pre-drilled for mounting in the mold and the molder is free to pour molten wax into the mold

The Lost-Wax Casting kit comes with a precast shell that can be reused multiple times, assuming that the original model does not show any cracks. Each shell is pre-drilled for mounting in the mold and the molder is free to pour molten wax into the mold. The molten wax has to be allowed to cool before it is poured into the molds. The molds are carefully designed to prevent air bubbles from formulating inside the mold during the casting process, as this can cause the mold to collapse.
