![]() ![]() If you are working with precious metals in a jewelry studio, you may work with silver, copper, gold, and platinum. Non-ferrous alloys most commonly used in casting are aluminum, bronze, and copper. Ferrous alloys include steel, malleable iron, and gray iron. Alloys are a mixture of elements that provide the best mechanical properties for the final cast’s use. Choose the metallic alloyĪll metal castings are produced from either ferrous or non-ferrous alloys. Heat in short bursts in the microwave until all of the wax has dripped into the small container. First, remove any metal clamps you might have added to your mold, then prop it up on clay supports over a small container underneath to collect the wax. The easiest way to melt the wax out of a small mold is in a microwave. ❗ When working with dry materials, make sure that your work area is well ventilated, and wear a respirator when working with dry investment. Plaster gives the mold support and silica has a high refractory, so it can withstand a lot of heat. Use a gram scale to measure each ingredient and mix equal parts by weight of plaster, silica, and water until the investment has the consistency of heavy cream. You can make a mold using a combination of plaster and silica. This is especially important if your design contains small intricate elements that may not fill with metal during the casting process. ![]() Patterns may also be gated with sprues to allow the molten metal to flow into the mold. When shaping your pattern, make sure you account for any anticipated shrinkage when the metal cools. Many experienced wax sculptors swear by repurposing dental tools to sculpt and carve unique designs in wax effectively. After that, shape it with texturing tools, a soldering iron, and a heat gun. To learn more, head to our glass casting guide.Ĭreate your desired design in wax before building a mold around it. You can also use lost wax casting techniques to create cast glass objects. This guide focuses on the lost wax casting process with metallic alloys. The wax model makes an expendable mold that can only be used once in casting. It can be used to create objects from simple to complex in various metals by casting an original wax model or pattern. The process is used to create parts for transportation, agricultural, and medical industries, to name just a few. The precision and accuracy of the process have made it an ideal method for producing objects with thin walls, intricate details, and close tolerances. Lost wax casting is a 6,000-year-old process still used in both manufacturing and fine art. to visually capture the stories of ancient cultures and religions throughout history. This ancient method has been used since 3000 B.C. Using this method of casting captures fine details in both metal and glass. After the mold investment is set, the wax is melted out and forms a cavity where the metal or glass flows in. Lost wax casting builds a mold around a sacrificial wax model. This guide will cover how to start lost wax casting and what you can create with the process. It is a highly versatile process that achieves exceptionally detailed results. Lost wax casting, also known as “investment casting,” is the process by which a single metal object is cast from a wax model.
