Investment casting is also called “lost wax” casting, it is one of the oldest metal-forming processes in the world. Today, with more advanced waxes, slurry of fine refractory material, temperature and humidity control system, and modern equipment, investment casting is still one of the most used manufacturing methods to create complex and detailed cast metal components for a variety of different industries.

Investment casting offers high dimension accuracy, smooth surface finish and good mechanical properties of the parts. A wax pattern of the required part is produced by injecting wax into a mold, the desired metal is poured into to mold after “lost wax” process. We get a finished casting part once the liquid metal is solidified. If you want to know more about the investment casting process, please have a look at our detailed step by step guide of investment casting process.
