Investment casting (water glass process)

Water glass investment casting is a casting process where a water glass (sodium silicate) and refractory material mixture is used to create moulds. A wax pattern is coated with the water glass mixture, forming a ceramic shell. Upon heating, the wax melts, creating a mould cavity. Molten metal is then poured into the mould, and once solidified, the ceramic shell is removed, resulting in finely detailed castings suitable for various applications.

• Intricate Designs: This method excels in producing intricate and detailed designs with precision, ensuring complex components are accurately cast.
• High Dimensional Accuracy: Water glass investment casting offers tight tolerances, minimizing the need for extensive post-casting machining.
• Surface Finish: The process results in smooth and refined surfaces, reducing the need for additional finishing steps and enhancing the final product’s aesthetics.
• Consistency: Water glass investment casting ensures consistent and repeatable outcomes, crucial for maintaining product quality and specifications.
• Cost Efficiency: Despite initial tooling costs, the reduced post-casting processing and higher precision often lead to long-term cost savings.
