what is the difference between steel casting vs sand casting


Valve casting

The current market is booming with a lot of casting services. It is due to the rapid growth seen in the industries. With every progressing day, the equipment and methodologies associated with industrial practices are becoming more modernized.

Speaking of castings, there are, however, two prevalent types of casting procedures which are still very useful today. The first one is called Steel casting and the other one is called Sand casting.

Here is a detailed analysis of both of these castings along with their pros and cons. This would be quite helpful for an individual to determine the kind of service they truly require for a forthcoming project.

Information about Steel Casting and What is It about?


In a steel casting process , the immensely hot liquid metal is allowed to flow under extremely high pressure. In such practices, the steel mold is allowed to be poured upon a hollow cast, from where it eventually takes up the form of the product that is to be manufactured.

After the steel is poured and left to cool down, you are left with solid steel casting which has taken the shape of the hollow region. As the metal cools down, it gathers its integrity and solidifies to being cold steel, as it originally was.

After the process is done with, the container containing the red hot liquid metal is closed immediately, and the next batch is prepared. The whole process is meant to be completed at a very high speed while the liquid metal is still boiling. Roughly, each batch takes somewhere around half a minute to complete.

What about the Sand Casting Process?


Sand castings work on the basic principle of pouring the hot red metal and letting it solidify. For these cases, a ladle is used to drain the molten metal into a sand mold. Sand Castings, however, do not require a high pressure to carry out this job and thus could be preferred by the masses.

This process requires a pattern block that resembles the exact shape, size, and dimensions to that of the final product that is to be manufactured. The material used for making the dummy pattern block could be wood or even plastic.

After the block is ready, an airtight system is prepared where the pattern block is covered with sand all around it. Sand is used due to its cohesive and adhesive properties. These attributes let sand particles to stick with others even when there is a disrupt change in their surroundings.

The molten metal is then poured into the system, and the liquid metal replaces the hollow part, which was made out of the pattern block.

This process could take more time than a Steel casting. There must be at least five minutes for the molten metal to solidify and prepare for the next batch.

As we can see a lot of the sand casting Companies are trusted due to their straightforward approach. Though a sand casting requires more time to settle down, the tools and conditions which are necessary to carry out this job are easily met.
