There are two main investment casting processes used in the industry: the Silica Sol process and the Water Glass process. Each has its own advantages depending on the complexity and size of the part.
The Silica Sol process is ideal for producing intricate, high-quality components with excellent surface finish and tight dimensional tolerances. It can be used for parts ranging from just a few ounces up to around 80 pounds. This method is particularly effective for small, detailed parts such as teeth, gears, and serrations where precision is essential.
On the other hand, the Water Glass process is more commonly used in earlier stages of investment casting. While it can handle larger castings—up to about 200 pounds—it typically offers slightly lower surface finish and dimensional accuracy compared to the Silica Sol process. However, it still provides better results than traditional sand casting methods.
All first article samples come with detailed layouts and spectrometer material certifications to ensure quality and compliance with specifications.
Custom services are available for both types of castings, including heat treatment, machining, plating, painting, polishing, assembly, and custom packaging. These additional operations help meet specific customer requirements and enhance the final product's performance and appearance.
