Advantages of Silica Sol Casting Process
- Exceptional Surface Finish: Achieves surface roughness as low as Ra 1.6μm.
- Dimensional Accuracy: Maintains tolerances within ±0.1mm for most applications.
- Material Versatility: Suitable for a wide range of alloys, including stainless steels,carbon steel and super alloys.
- Complex Geometry: Enables production of intricate metal parts with thin walls and fine details.
- Cost Efficiency: Reduces machining requirements and material waste.
Silica Sol Investment Casting Process:
- Make the pattern: Use an injection molding machine to create precise wax patterns.
- Assemble the tree: Once the wax patterns are made and repaired, put them together to form a tree shape.
- Apply slurry: Dip the patterns into silica sol-based ceramic slurry. Add multiple layers this way.
- Add stucco: Put refractory materials between the layers. This makes the shell stronger.
- Remove the wax: Heat the assembly to melt away the wax pattern. This leaves a hollow ceramic mold.
- Roast the shell: Fire the ceramic shell at high temperatures. This gives it its final strength.
- Pour the metal: Pour molten metal into the prepared mold.
- Take off the shell: Let the metal cool, then break away the ceramic shell. The cast part is now visible.
