Cast iron

one of the methods of making and forming metals in desired shapes is called cast iron casting. From the past until now, to make metal parts, a series of molten metals such as iron, cast iron, and aluminum were poured into special molds and then a series of molten material injection operations were performed on them. The shaping and hardening of cast iron parts is called casting of cast iron parts. Cast irons are composed of compounds such as iron, carbon and silicon.

A series of methods are used for casting cast iron. These methods are exactly the same as the methods of casting steel parts.

Muscle is a component independent of the mold, which plays the role of creating the main internal compartments in hollow parts. They also use muscles in external appendages that are not on the same level as muscles instead of free parts. If the muscle molds are complicated and there is no ability to beat the sand by manual methods, the sand is injected into the molds by wind pressure and in blowing mode. The molten material is then transformed into a solid piece of cast iron or steel in casting parts.

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 into them, which will cause the sand particles to stick to each other. By using this method, you will give higher precision and less turning to the casting of cast iron parts. When the mold comes out, the shape of the molds will be created on the sands.

Basically, these molds should be converted into final molds by the companies producing the desired part, with appropriate designs for the CNC machine. After going through the steps of making a mold, another mold is made, which is called grade. Grades are metal molds in which the main mold is placed.

As we have already mentioned, in principle, in the casting of steel parts, the construction of grades should be given importance. Grades are a metal coil that includes the main molds. They make grades depending on the amount of sand and the height. Grades are produced in two models. They are produced in the form of aluminum and steel or welded iron as a mold.

The next step is to collect block and iron scraps and transfer them to the furnace. At this stage, iron and cast iron scraps are put in the furnace at a high temperature and wait for it to melt. Cast irons will melt at a temperature of 1200 degrees. When melting the materials, operators add silica to cast iron parts efficiently.

After the molten material hardens and hardens inside the mold, it is time to separate and separate the molds. Different steps are followed to separate them. This operation is done manually or by means of vibrator devices. In manual methods, the molds are separated from the grade with the strength and ability of the hand, but in mechanical methods, the molds are separated from the grade using the vibration of vibrator devices.

After the parts are separated from the sand molds, they are completely clean and uniform using devices called shot blast. As a result, the casting of steel parts will be performed well at this stage.

One ​​of the methods of making and creating the form of metals in different dimensions, shapes and sizes is cast iron. From ancient times until now, in order to make metal pieces, materials and molten metals such as aluminum, iron, and cast iron are poured into special molds and thus give shape to the metals. In general, the process of injecting molten material into a mold and forming and hardening it is called casting. The metal parts produced by Isfahan Casting Company by casting method have fruitful use in many industries, hence it can be said that the casting industry is very important today. Cast iron has different methods, each of which is used depending on the type of need and intended purpose.
