One of the methods of making metals in the desired shapes is called cast iron casting. In the past, to make metal pieces, a number of molten metals such as iron, cast iron, aluminum poured into special molds and then performed a series of molten injection operations. Casting pieces are called cast iron parts. Cast iron consists of compounds such as iron, carbon and silicon.
Types of unique methods of cast iron casting
A number of methods are used to cast cast iron. These methods are exactly the same as steel casting methods that we will examine below.
Dactil or tight cast iron
CO2 Sand Method
In this method, silica sand is used for molding and the adhesives used in this method are sodium silicate adhesives. These adhesives produce silica by blowing CO2 gases, which will attach sand particles to each other. By applying this method, you will give you a higher accuracy and less turning to cast cast iron. When the mold exits the form of the molds will be created on the sand.
Protective muscle method
The muscle is an independent component of the mold that plays the role of the main interior in the empty parts. The muscles are also used in external appendages that are not on the same level from the muscles rather than free parts. If the muscle molds are complex and the ability to crush the sand is not available in manual methods, the sand is injected into the molds with wind pressure. Then molten materials are converted into a piece of cast iron or steel in the casting of parts.
The main steps of cast iron casting
cast iron casting is composed of various stages that we will discuss below.
The original design of casting molds
These molds must be converted by the companies in the desired part of the CNC device in the final templates. After the process of making the mold is made, another mold is made, which is called a degree. Grades are a metal mold that is the main mold inside.
The construction of metal casting grade
As we mentioned earlier, steel components are essentially important in the casting. The degrees are a metal coil that encompasses the main molds. Depending on the amount of sand and height they make the degrees. The degrees are manufactured in two models. They are produced in aluminum and steel or welded iron like mold.
Melting of doctr cast iron
Separate casting molds
Once the molten material is hard and stiff, it is time to separate and separate the molds. It is followed by different stages to separate them. This operation is performed manually or by vibrator devices. In manual methods with the strength and ability of the molds, the molds are separated from the degree, but in the mechanical methods, the vibration of the vibrator devices separate the molds from the degree.
The last and final stages
After the components are separated from the sand molds, they are completely clean and uniform using devices called Shot Blast. As a result of casting steel pieces will also be well executed at this stage.
