At Jinzhou Eco Precision Castings, we utilize the Water Glass Casting method to deliver high-quality steel castings with excellent surface finishes and precise dimensional tolerances. This technique offers an economical solution for industries requiring reliable and detailed components, especially for medium-to-large series production.
What is Water Glass Casting?
Water glass casting, also known as the sodium silicate investment casting process, involves using a liquid silica-based binder (water glass) to create molds. These molds provide the stability needed for intricate designs while being cost-effective for larger production runs.

The Process
- Mold Creation: Wax patterns are dipped into a water glass binder and coated with refractory materials to form a durable shell.
- Dewaxing: The wax inside the shell is removed by melting, leaving behind a hollow cavity.
- Casting: Molten metal is poured into the cavity, capturing intricate details from the mold.
- Cooling and Finishing: Once the metal solidifies, the shell is broken away, and the casting is cleaned and finished to meet customer specifications.
Advantages of Water Glass Casting
- Cost-Effective: A more affordable alternative to precision casting methods like lost wax, particularly for larger series.
- Strong Mold Integrity: The water glass binder creates a robust mold capable of handling complex designs.
- Versatile Applications: Suitable for medium-to-large components in various industries.
- Fine Surface Finish: Achieves a smooth exterior, reducing post-processing requirements.
- Dimensional Precision: Provides reliable tolerances for functional and aesthetic parts.
