What is carbon steel casting?
When carbon steel is put for casting, the finished product of that process is called as carbon steel casting. Technically speaking, carbon steels are those steels that contain only residual amounts of substances other than carbon, silicon, aluminum along with manganese and cerium.
There are two types of carbon steels namely low carbon steels and medium carbon steels. While low carbon steels contain only 0.15% carbon, medium carbon steels contain about 0.25-0.55% carbon content. Therefore, low carbon steels are mainly used for applications that require metals with high ductility. On the other hand, medium carbon steels are often heat-treated to gain yet higher strengths.
The following are the components of carbon steel casting. Carbon maximum 0.04, manganese maximum 1.0, silicon maximum 1.0, phosphorus maximum 0.04, sulphur maximum 0.04, chromium maximum 24.5-26.5, Nickel maximum 4.75-6.0, Molybdenum maximum 1.17-2.25, copper maximum 2.75-3.25. These are the main components of carbon steel casting.
Carbon steel casting can be manufactured by Sand casting, Investment casting, Permanent mold casting, Lost foam casting, etc. Here, I will attempt to explain a couple of these methods in brief.
Sand casting is one of the most popular, simplest and cheapest type of casting. This method has been used for centuries together with good results. This method allows manufacturers to cast the material in smaller batches and that too at a very reasonable cost.
Therefore, merchants with very small size of operations can use this method successfully. Not only is it cost effective, but it is also suitable for people who have small operations. Also, sand casting is a method that allows most of the metals to be cast depending upon the type of sand used for the molds.
Investment casting derives its name from the fact that the casting pattern is invested or surrounded by refractory materials. This method has been practiced since thousands of years. This process is also called as the lost wax process and it is one of the most ancient metal forming techniques.
This method ensures that high quality components are produced accurately, repeatedly and with integrity. Although, this process is mainly suitable for small castings, this method has produced aircraft door frames with steel castings up to 300 kilograms and aluminum castings up to 30 kilograms. Thus, this method is also for small scale operations.
Advance Technologies of Casting Companies
The other popular name for investment casting is lost wax casting, is a traditional casting process suitable for précised castings worldwide. Today, plenty of casting companies love to use investment casting process for manufacturing their products. You can also check list of casting companies on-line available near you. Investment casting is usually preferred for thin wall and complex metal castings. The process assures accuracy, precision, required shape and designs.
Process followed by casting companies
The process starts by mold creation that has similar shape as finished product. The mold is usually created using different types of wax that will get melted during casting process. First of all, you have to pour metal into wax mold and allow it getting solid. After solidification, casted metal should be removed away carefully to avoid damage. Take help from casting companies in India to achieve desired shape and thickness. Also discuss about specifications with expert and which raw material is suitable for desired investment casting.
Place the mold inside oven that will melt the wax and one piece mold is obtained finally where you can fill desired metal to obtain final product. Today, experts at certified casting companies in India use computer aided technology for designing accurate and précised molds. The most common examples are aircraft parts, hand tools, ornaments, turbine blades and jewelry.
Here you can use variety of wax to design final casting product. Your specific usage and industrial application will decide type of wax that should be used for your product. The most popular types are:
- paraffin wax
- petroleum wax
- emulsified wax
- low expansion wax
- straight pattern wax
- industrial casting wax
- wax for making repairs
- filled pattern wax
Different types of wax has different melting point and suitable for different industrial applications. To know more on our products, contact expert team of engineers and specialists conducted with casting companies for valuable solutions and information.
Casting is a process that involves pouring of the liquid metal into a mold, which has a hollow cavity of the desired shape. After this liquid metal solidifies or cools, the solidified part is called as a casting.
This casting is forcibly removed from the mold in order to complete the whole casting process. Casting is an economical method to produce shapes which cannot be produced by other methods. Modern casting methods are divided into expendable casting and non-expendable casting process.
These methods are further classified based on the mold material used and the pouring method. The casting process used in the above method can give you good quality carbon steel casting.
