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.
A process which involves the creation of jewelry pieces is referred as jewelry casting. The process includes pouring the liquid metal alloys into the molding. Ever since, the technique is being used already and also until now, craftsmen and home crafters have been utilizing this for originally made jewelry pieces. When deciding to create one, follow these easy steps for a 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.
Investing the molding. Be sure to have a secured wax model stand from the bottom of casting flask. Secure this by the use of a small amount of a melted wax. See to it that your model is popped up top the flask. After this method, prepare the product for the process of casting. With the use of water, mix all the dry ingredients by following the specific instructions being provided in the mold investment you have chosen.
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 your jewelry. The metal you have chosen is then placed into pouring crucible then is melted in a foundry. Both time and temperature are dependent on the metals being used. After pouring the metal into molding, cast it by the use of centrifugal machine. Centrifugal machines are used very commonly by those 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.
