Product Description
Silica sol Investment Casting, often referred to as the lost-wax casting process, is a manufacturing technique used to produce intricate and complex metal components with high precision and surface finish. In this process, a wax pattern of the desired part is created and coated with a ceramic slurry containing silica sol (a suspension of silicon dioxide nanoparticles in water). Once the ceramic coating dries, it forms a hard shell around the wax pattern.

The wax pattern is then melted or "lost" from the ceramic shell by heating, leaving behind a cavity in the shape of the desired part. Molten metal is then poured into the cavity, filling the space left by the wax pattern. After the metal solidifies, the ceramic shell is broken away, revealing the finished metal component.

Silica sol investment casting offers several advantages, including:

  • High Precision: The process allows for the production of intricate and complex shapes with tight tolerances, ensuring precise final dimensions.
  • Smooth Surface Finish: Components produced through silica sol investment casting typically have a smooth surface finish, reducing the need for additional machining or finishing processes.
  • Versatility: It can be used to cast a wide range of metals and alloys, including stainless steel, carbon steel, aluminium, and more, making it suitable for various applications across industries.
  • Fine Detailing: Silica sol investment casting can capture fine details and intricate features of the original pattern, resulting in highly detailed final products.

Overall, silica sol investment casting is a versatile and efficient manufacturing process ideal for producing high-quality metal components used in industries such as aerospace, automotive, marine, and more.


A & M Manufacturing Company Ltd's Silica Sol Investment Casting Technique:

Over the years, our silica sol investment casting technique has undergone significant advancements, thanks to the continuous innovation and dedication of our research and development department. 

We have replaced water glass binders with silica sol binders, which has not only improved the working environment but also enhanced the quality of investment castings by eliminating the need for environmentally harmful curing agents like ammonium chloride and aluminum chloride liquids. 

Moreover, we have drastically reduced the drying time in the silica sol shell-making process from 8 hours per layer to just one hour, significantly boosting production efficiency and shell strength. Our expansion of silica sol technology now encompasses a wider range of materials, including carbon steel and various alloy steels, allowing us to offer investment casting parts weighing up to 50kg. 

This expansion has not only diversified our product offerings but also reduced production costs, particularly for historically expensive carbon and alloy steels. Additionally, we have successfully implemented a fully automated shell-making process, incorporating mechanical handling and automatic drying, which can create up to 8 layers of shells with precise control and without human-operated variability. Furthermore, our development of shells with increased strength and reduced thickness has enhanced shell permeability and contributed to the exceptional surface finish of our castings. Throughout these advancements, we have remained committed to environmental responsibility and sustainability in the investment casting process.
