  • Where Does the Wax Go When it Gets "Lost?"

    One of the parts of the investment casting process that I initially found hard to understand was the process of removing the wax patterns and runner from the ceramic shell once it hardens. If you scour the Internet's offerings on the lost wax casting process, if you find anything at all, it might not always be clear how the whole investment casting process works, let alone how each stage in the process is executed. This can be the case with a lot of industrial processes, and as someone who regularly...

  • The Brilliance of Lost Wax Casting

    Investment casting really is a brilliant process. The history of the practice dates back many centuries, and it has continued to perform well as a casting method ever since. There are many reasons why investment casting has persevered for such a long time, but the principal reason is this: investment casting works. The process has come to be known by several names besides investment casting, but the most meaningful and widely-used alternative name is probably lost wax casting. Lost wax casting is the most descriptive name in terms of how...

  • Understanding Wax Casting

    The fact that investment casting is also known as wax casting and lost wax casting can make it difficult for outsiders to understand the process. Lost wax casting is a bit of a confusing term, but wax casting just seems like an outright misnomer (at least when the term is used in connection with investment casting). After all, the investment casting process is not about casting a wax product and then being finished. Wax casting is only a small part of the investment casting process. It doesn't help that the...

Industry Information

Wax Casting

Wax casting is a process that uses a wax pattern to create metal parts. This technique is also called the lost wax or investment casting process. Aluminum, copper and stainless steel are among the most commonly used metals; almost any castable metal may be used including gold, titanium and brass. Due to the smooth surface of the wax pattern that is used to create a ceramic mold, the resulting parts have a very fine finish that requires little machining.

Wax casting is effective at producing complex and detailed parts that other manufacturing methods cannot. There are no seams, flashes or parting lines because the part is made as one whole piece. Because a wax model is created in the exact size and shape as the part, wax casting provides a highly accurate part. Castings can be fractions of an inch thick or weigh hundreds of pounds; most parts are around 15 pounds or less. Wax casting is a traditional metal part manufacturing process that has been used for jewelry making for hundreds of years. It is finding modern uses in a wide variety of applications including dental and medical tools, engines, couplings, fittings, pipes, propellers and in aerospace, automotive, dental, medical, electrical, construction, mining, food processing, telecommunication, plumbing, military, sports and other industries.  

Wax casting relies heavily on wax and its properties, though the actual wax is not necessarily pure; it may contain plastic or other substances. The wax can be carved by hand or machine but may also be produced through injection molding where hot wax is poured into a metal mold. Items such as preexisting patterns made from other materials may be covered in wax that is carefully removed when hardened then reattached. When the wax model is ready, it is attached to a wax sprue using a heated metal tool. Depending on the side and shape of the part, several hundred patterns may be attached to the same sprue resulting in an assembly called a tree which is dipped in ceramic slurry called the investment. It is dipped multiple times in mixtures that are increasingly coarse until the investment shell is thick enough. Another method is to place the tree in a flask and pour investment into the container until the tree is completely covered. Once the investment has hardened, the tree is inverted and placed in an oven or furnace. It is exposed to high temperatures during the burnout stage when the wax melts and runs out; all residual moisture is baked off. When removed from the oven, a liquid metal at very high temperatures is poured into the hollow shell. The metal cools within minutes and the shell can be removed, exposing the part within.
