Casting is a method in metalworking and jewelry manufacturing in which a liquid metal is poured into a mold (typically a crucible) that has a negative imprint (i.e., a three-dimensional negative image) of the desired shape. The metal is put into the mold through a sprue, which is a hollow tube.

Difference Between Carbon steel And Silica Sol Casting

Carbon steel is a steel alloy whose major alloying ingredient is carbon. Usually, the carbon content in carbon steel casting is 1%.  Cast alloy steels have been designed to withstand higher pressures, wear resistance, and higher strength while maintaining enhanced stiffness and surface hardness.

Carbon steel is classified into three categories based on its carbon content. Low carbon steel, medium carbon steel, and high carbon steel are the three types. For industrial tasks, many grades and methods are employed. Machine construction, industrial manufacturing, automotive components, and aviation and transportation projects are just a few examples.

Mild carbon steel is a versatile material with excellent ductility, strength, and wear resistance. Heat treatment can also be used to harden and temper it. Low carbon steel can be bent easily, but it cannot be reinforced by heat treatment. 

Silica sol investment castings offer superior dimensions and surface quality than water glass castings, but they are more costly. Silica sol casting is about twice as expensive as water glass casting. Investment casting, often known as a lost wax casting, includes both silica sol and water glass casting.

As a molding glue for stainless steel investment casting, silica sol serves this purpose. Because silica sol steel castings can have significantly superior surface quality and less geometrical variation of dimensions, they are primarily utilized for items with strong corrosion resistance and precision dimensions.
