We have two types of investment cast processes:Silica Sol process and the water glass process.

The Silica Sol process is used to cast complex high quality parts with requirements of a very good surface finish and close dimensional tolerances.

The water glass process is typical of the process in the early stages of investment castings. It generally is capable of much larger castings than the Silica Sol process, but does not have as good of surface finish or tolerances. The water glass process provides parts that have better surface finish and dimensional tolerances than sand castings.

Lost wax investment casting is a complex process that involves multiple steps, and various issues can arise during each stage of the process. Here are some common problems and solutions in lost wax investment casting:

Wax pattern defects: Wax patterns can be prone to defects such as air bubbles, cracks, and warping. To address this issue, it's important to use high-quality wax and ensure that the wax injection equipment is functioning properly. Additionally, inspecting the patterns before investing can help catch any defects early on.

Ceramic shell cracking: Ceramic shells can crack during the investment process or when the molten metal is poured into the mold. To prevent this issue, it's important to use the right type of ceramic shell and to ensure that the shell is properly dried and fired before pouring the metal. Proper handling and placement of the shell is also important to prevent cracking.

Surface defects on castings: Surface defects such as porosity, shrinkage, and cracks can occur in the final castings. These defects can be caused by various factors, such as poor wax patterns, improper gating and venting, or poor quality control during the investment process. It's important to closely monitor and control all aspects of the process to ensure that the castings are free of defects.

Dimensional inconsistencies: Dimensional inconsistencies can occur if the wax pattern shrinks too much or if the ceramic shell is not uniform in thickness. This issue can be addressed by properly controlling the wax pattern injection and the investment process to ensure consistent and accurate dimensions.

Metal defects: Various defects can occur in the metal casting, such as cracking, cold shuts, and inclusions. To prevent these issues, it's important to use high-quality molten metal and to ensure that the metal is properly poured into the mold. Proper gating and venting of the mold can also help prevent metal defects.
