Investment casting is an industrial process based on lost wax casting, one of the oldest known metal forming techniques. The term "lost wax casting" can also refer to the modern investment casting process.
Over the past 5,000 years, investment casting has been used in various forms. In its earliest form, beeswax was used to form the patterns required for the casting process. Today, more advanced waxes, refractory materials, and specialty alloys are often used to create patterns. Investment casting is valued for its ability to produce parts with precision, repeatability, versatility and integrity using a variety of metals and high-performance alloys.
Fragile wax patterns must withstand the forces encountered during moldmaking. Most of the wax used in investment casting can be recycled and reused. Lost foam casting is a modern form of investment casting that eliminates certain steps in the process.
