What Is Casting? Define Water Glass Casting?

Casting is a manufacturing method that is used to obtain complex shapes with minimum effort. After the introduction of casting, it was used for manufacturing various tools, weapons, and some type of religious object. But, as the industry of foundry is developing very fast, various new casting techniques are introduced for obtaining precise products with less cost and effort. 

Different custom parts that are used in different types of machinery are often obtained by various casting procedures. Some famous and most used types of casting are written below:

  • Silica sol casting
  • Water glass casting
  • Alloy steel casting
  • Carbon steel casting
  • Stainless steel casting
  • Sand casting, and more. 

Among various types of casting, the most used casting is silica sol casting and water glass casting. In this article, we will go through the benefits one can enjoy by using silica sol casting and water glass casting. 

Benefits of silica sol casting:

  1. Silica sol casting belongs to the category of lost wax casting. It has the ability to produce objects with high surface quality, high molding accuracy, as well as also possesses fine mechanical properties. 
  1. A low shrinkage rate is observed in products while using silica sol casting. The transverse shrinkage rate of silica sol casting is only 0.3% to 0.5%, which can be controlled within 0.2% by scientific formula design and strict process control.
  1. Silica sol casting is a little bit costly as compared to other casting techniques, but excellent results can easily compensate for the price. 

Benefits of water glass casting:

  1. Water glass casting is preferred over sand casting because it provides an excellent surface finish.
  1. Complex structures can easily be obtained through water glass casting.
  1. It is affordable as compared to investment casting.
