What is Silica Sol Investment Casting?

Silica sol investment casting (also known as lost wax casting or precision casting) is a manufacturing process where a wax pattern is coated with a ceramic shell made of silica sol. The wax is then melted out, and molten metal is poured into the cavity. This process produces complex parts with excellent dimensional accuracy and surface finish.

Advantages of Silica Sol Casting

  • Excellent surface finish (Ra 3.2-6.3 μm)
  • High dimensional accuracy (CT4-CT6)
  • Ability to cast complex geometries
  • Minimal post-processing required
  • Suitable for small to medium batch sizes

Materials We Cast

  • Stainless steel: 304, 316, 316L, CF8, CF8M
  • Duplex stainless: 2205, 2507
  • Carbon steel and alloy steel
  • Heat-resistant steel

Industries Served

  • Pump & Valve manufacturers
  • Marine & Yacht hardware
  • Food & Beverage equipment
  • Automotive components
  • General industrial machinery
