The process of melting down the metals into a liquid form and pouring them into a casting mold made out of sand or other materials is called metal casting. The metal that needs to be cast in a certain shape is first liquefied and then this liquefied metal is poured into the casts. These casts are designed to give the metal a desired form. The final product then sent off for polishing and distribution processes. The best part of metal casting is that one can reconstruct the same product effortlessly. A prototype is used to create the mold and then exact replicas are made using the metal casting process.
Aluminum sand casting used to be popular but now more and more companies are opting for alloys such as steel, stainless steel, bronze, brass, etc. Here are the main reasons why metal casting is still so popular in the world:
• Wide Suitability: The process of metal casting is almost free from all the size, shape, and thickness restrictions. One can keep the thickness of a metal up to 0.3-1000mm. Similarly, quantity can also go up to 300+t. Metal casting is considered as the perfect option for the parts manufacturing with complex shape and cavity. Complex parts such as valve, engine cylinder, impeller, propeller, boxes, etc. can be produced easily through the metal casting process.
• Availability of Materials: All the materials used in metal casting are available easily. Almost every material such as steel, stainless steel, different aluminum alloy, iron alloy, copper alloy, platinum alloy, etc. can be used for casting. For breakable alloy materials like ordinary cast iron, casting is the best possible forming process.
• Size Accuracy: When circumstances are normal, metal casting has more accurate forming size than the usual welding parts and forgings. This accuracy of size makes this casting process so relevant for various manufacturing industries. Each replica is the exact copy of the prototype in terms of shape, size, etc. even though the weight may differ slightly.
• Lower Cost: When you compare the overall material consumption, economic performance, and energy, you will find a huge difference in the overall cost of metal casting as compared to other processes. For instance, the production method of metal casting is more flexible, hence mass production can be arranged easily. Also, the waste material can be re-used for production. Power consumption is also lesser than any other method. Metal casting is the way to maximize the profit with minimal investment.
