Unlike other casting techniques, investment casting makes parts from molten metal. This process is also known as lost-wax casting, and has been done for thousands of years. Understanding the basics of investment castings is essential to know when and how to use this method. Let’s start with the basics of this method.
In this method, parts are made from molten metal. These metals are typically stainless-steel alloys, carbon steel, brass, and aluminum. What makes this process unique is how the parts are formed. First, a wax version of the final product is made. This can be done with a 3D printer, a metal mold filled with hot wax, or a wax replica of the final product. If multiple parts need to be casted at once, the parts can be connected using wax runners and sprues to create a “tree”. Next, the molten metal is poured into the molds. Once the mold is solidified, the ceramic mold is broken or destroyed to remove the parts.
Compared to other methods, investment casting uses ceramic molds that are hard. This results in smooth surfaces. Additionally, investment casting gives engineers more freedom to create intricate features and complex shapes. This is because the process uses liquid slurry to form the molds.
