The term “investment” refers to the process of the ceramic slurry application. There are two main techniques to encase wax patterns in the high temperature ceramics which eventually become the mold to hold molten metal. One method is pouring ceramic slurry around a wax tree assembly that is inside a container, and the second is to dip the wax into the slurry to apply the slurry in layers. When any object is dipped into a liquid, and that liquid stays on the surface, that is called investing, and hence this is where the name comes from. The process is sometimes also called the “Lost Wax” process, reflecting the fact that the patterns are disposable, as well as “Precision Castings”, which reflects on the accuracy and fine detail of the castings themselves.
The investment casting process offers many unique benefits over not only other casting processes, but also over many other common manufacturing processes, such as machining, welding, forging, stamping, and assemblies. Examples of these benefits are :
Design Freedom:
1.The investment casting process allows the designer the flexibility of nearly infinite alloy choices, and great flexibility in external and internal configurations.
2.Unlike other casting methods, there are no draft requirements in the investment casting process, allowing for much more accurate dimensional conformance.
3.Reduced Machining: Investment castings are produced to close tolerances and near-net size. There is little secondary machining required, thus offering savings in machining time and material costs.
4.Mechanical Properties: Investment castings will usually be able to meet the same mechanical properties of components manufactured from wrought metals.
5.Superior Aesthetics: The surface finish of investment castings is consistently better than 125 RMS. Fine details, text, logo’s and design features not attainable with other processes are possible.
6.Reproducibility: The investment casting process produces a reliable and consistent product.
