One of the most widely used processes of manufacturing applied in most industries like automobile, construction, agriculture, and equipment, cast iron casting is globally renowned due to its flexibleness, strength, and economy, due to which it’s a material universally accepted on an international scale when it comes to manufacturing hard as well as intricate components. If you are curious about how CI casting is produced or need to locate a quality CI casting company or CI casting factory, going through this step-by-step process will guide you through the entire production process.

We at Sagar Foundry promise to deliver industries the finest CI casting services. Below we detail how CI casting is done from pattern making to finishing and why it’s so critical of a manufacturing process nowadays.

What is CI Casting?                                  

Cast iron casting is the method of making molten iron cast into a mould to produce a given form. A long-lasting and robust component is produced as the molten metal cools by hardening and assuming the form of the mould. Manufacturing components with complicated forms, great strength, and maximum wear resistance will find the technique most appropriate.

Step 1: Pattern Making

The first step in the CI casting is to create a pattern. A pattern is an exact duplicate of the finished product, frequently made of wood, metal, or plastic. It is used to form the mold cavity in which molten iron is poured.

The pattern is built based on the technical drawing and specifications of the end product. It’s bigger than the end product so that when it cools, it shrinks. Patterns are usually built with moldable material that is strong enough to withstand the molding process. At Sagar Foundry, we use advanced design software and accurate machinery to create precise patterns that yield the best castings.

Step 2: Mold Preparation

After the preparation of the pattern, the preparation of the mold is the next step. Enveloping of the pattern is done by using molding sand. Two types of molds are applied in CI casting, i.e., green sand molds and dry sand molds.

Green sand molds consist of clay, sand, and water and hence are very cheap and can be used extensively for small- and medium-sized castings. Dry sand molds are baked out, though, in order to expel the water, thus making them stronger, and for more complicated or larger castings. Molding sand is pressed around a pattern, and the pattern is also covered with a flask. The flask is halved so the pattern may be removed, with a cavity similar to the completed product. For the zones of hollow parts, metal centers or sand is let into the core of the mold.

Step 3: Melting and Pouring

Forming the cast iron melt and pouring the same into the mold forms the CI casting’s core. Cast iron is melted in a furnace in the range of 2,100°F to 2,400°F (1,150°C to 1,300°C). Just the proper combination and heat are in liquid iron.

After being heated to the required temperature, the molten iron is filled into the mold cavity through a gating system. The gating system provides uniform and uniform flow of the metal in a way that no deficiency like air bubbles or under-filled regions is made. We at our company, Sagar Foundry, make high-quality molten iron by employing latest furnaces and rigorous quality checks.

Step 4: Solidification and Cooling

After casting is completed, the iron hardens and cools in the mold. Cooling takes time depending on the size and complexity of the casting. While cooling, iron contracts, hence patterns are designed with shrinkage allowances to allow for contraction.

The iron cools from outside to inside, and hence a very hard and strong solid piece is created. The cooling is properly carried out so that the required mechanical properties as well as proper dimensions are imparted to the casting.

Step 5: Mold Removal and Cleaning

After cooling and hardening of the casting, the mold is opened to find the raw casting. The mold is demolished with a shakeout process using vibrating equipment which would otherwise be utilized to shake out sand from the casting.

The casting is subsequently washed to eliminate any remaining sand, scale, or dirt. Cleaning could be done using shot blasting, grinding, or some other form of cleaning. Cleaning is a critical process in an attempt to release the casting from any defects so that it will be finished.

Step 6: Finishing and Inspection

Finishing and inspection are the ultimate operations of the CI casting process. Machining of the casting can be done to provide the required shape and surface finish. Operations of drilling, milling, and turning are used for improvement in the quality of the casting.

The casting itself can also be surface treated in a way that its properties can be improved, i.e., corrosion resistance or wear resistance. The finished product is inspected for defects, size, and quality. Visual examination, ultrasonic examination, and X-ray examination are routine to verify whether the casting is as per specification.

In Sagar Foundry, we have very high quality control and use the latest inspection methods to ensure every casting is in accordance with our customers’ requirements.

Advantages of CI Casting

Cast iron casting is beneficial in many aspects because of which it finds extensive application in a vast range of industries. The method can be used to manufacture parts that can be long-lasting with the co-existence of the chemical environments along with them. The method is also applied in the manufacture of parts with complex geometry and structure.

Moreover, CI casting is also economical, particularly for mass production. Machinability of high cast iron is most suitable for accurate parts, and wear resistance makes it longer-lasting.
