The water glass investment casting process (sodium silicate process) is a cost-efficient method widely used for producing intricate metal components in industries like automotive, energy, and general engineering. KEWEI, a global ISO 9001-certified leader in foundry solutions, optimizes this traditional technique with modern automation and material innovations. This article explores how KEWEI’s casting process delivers precision, scalability, and 30% lower production costs compared to ceramic shell methods.
1. What is the Water Glass Investment Casting Process?
The water glass process uses sodium silicate binder to create refractory shell molds around wax patterns. KEWEI enhances this method with:
- Fast Cycle Times: Shell hardening in 15–30 minutes via CO2 gas curing.
- Material Savings: 40% lower binder costs vs. ceramic slurries.
- ECO Compliance: Water-based, low-VOC materials meet REACH standards.
