Lost wax casting is a type of process where in the sculpture of a duplicate metal is being casted from the original sculpture. Examples of these materials would include gold, bronze, silver, or brass. Depending on the skills of a sculptor, the intricate works may be achieved through this method. Today, the process has been varied from different foundries and the steps being utilized are standardized fairly, specifically for the bronze sculptures.
Jewelry casting is the process in making pieces of jewelry involving a liquid metal alloy being poured out into molding. This technique was being used even in history, but still is used widely used until now by most home crafters and craftsmen in making original pieces of jewelry. So if ever you are interested on making your own product, follow these simple methods for lost wax casting jewelry.
Crafting the molding. Start on carving hard modeling wax pieces which are based on your desired shape. One suggestion in this method is creating only a very simple piece. Do not start on the complex if you are still a beginner. When making your model, commonly used tools would include Dremel and precision knife. Attach 3 to 4 sprues because these will provide the waxes channel for it to melt out.
Attach the molding to the base of sprue. This can be done by using an amount of melted rubber. The process will be allowing the top of wax to be melted at the bottom of base. And after, leave it for some amount of time. A flask will then be placed on the top of a sprue base. When doing this, make sure to leave a distance of about a quarter inch between the model and flask wall.
Invest your molding. Secure the stand of wax model into the casting flasks bottom using a melted wax. Make sure that the model will be popped up into the flask. In this method, the product is now ready for casting. Mix all dry ingredients with water. Based on the instructions provided in your chosen mold investment, follow them carefully.
Place the mold investment in the vacuum chamber for the removal of air bubbles. If the vacuum sealer is not acquired, you may just set it aside for about 10 to 20 minutes. Air bubbles often result to having some holes in the final product. After the mold has been dried, place the flask inside a kiln for about 600 degrees Celsius. After a certain amount of time, remove it and check if there are any obstructions at the bottom of mold.
Casting the jewelry. The metal of your choice will then be placed to a pouring crucible then it will be melted in foundry. The time and as well as the temperature depend on what kind of metals being used. After the metal is poured into the molding, use the centrifugal machine to cast it. These machines are commonly used by professional makers.
Allow first the metal for cooling for about 5 to 10 minutes and dunk it into a cold water slowly. The time will also depend upon the metal being melted. Gently tap your mold using a hammer so that the excess plaster will be broken.
Finish your jewelry. Get an angle grinder in cutting lines from the sprues. Hand held grinders are recommended for use than angle grinders since these are more strong. In the firing process, the metal may surely be dingy and dirty. So use some specific washers of metals.
