Technical Parameters

Water Glass Casting Parts:

Custom Water Glass Casting Parts offer a cost-effective solution for producing complex ferrous metal components with excellent dimensional accuracy. As a leading precision casting manufacturer in Ningbo, China, we specialize in delivering high-quality custom water glass casting parts for food machinery, agricultural equipment, and industrial applications worldwide.

What is Water Glass Investment Casting?

Water glass casting, also known as sodium silicate investment casting, utilizes water glass (Na₂SiO₃) as the ceramic binder to create durable molds around wax patterns. This process delivers superior surface finish and tighter tolerances compared to traditional sand casting, while remaining more economical than silica sol casting. The technique is particularly effective for medium to large-sized steel and iron components weighing 0.2kg to 150kg.
