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.
The process of casting jewelry involves making some jewelry pieces and this would include pouring liquid metal alloys into a molding. Since before, the technique has been utilized already and even until now, this is still being utilized widely, usually by the home crafters and the craftsmen when making original jewelry pieces. So whenever you have decided on starting to create your own piece, follow these methods in 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 your molding. Make sure that the wax model stand is secured to the bottom of a casting flask using an amount of melted wax. Be sure to pop up the model to the flask. With this method, your product will now be ready for the casting process. Mix the dry ingredients in water. Follow carefully the instructions being provided in your purchased mold investment.
Place your mold investment inside a vacuum chamber in order for the air bubbles to be removed. If there is no vacuum sealer, you can just leave it for awhile like for ten to twenty minutes. Having air bubbles may result to having holes. When the mold is dry already, place the flask in kiln having 600 degrees Celsius. Then after, remove it then check for some obstructions in the bottom of your mold.
Cast the jewelry. Place the chosen metal into the pouring crucible and melt it in the foundry. The temperature and the time of melting will depend upon the type of metals. When the metal is poured to the molding, you may use a centrifugal machine for casting. This machine is often being used by the professional makers.
The metal should be cooled first, usually for five to ten minutes then dunk it slowly to cold water. The time also depends on the melted metal. Tap gently the mold by a hammer to break any excess plaster.
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.
