What are the benefits of casting?
Beyond the emerging technologies that make metal casting at the forefront of the metal industry, the casting process has many inherent advantages that It has long been accepted by design engineers and users of the metal sector. In terms of component design, die casting offers the most flexibility for any metal forming process. The casting process is ideal because it allows the formation of simple, complex, strong parts that are not possible in any other way.
1. 1. Widespread sustained casting
The process of metal casting is almost free of limitations on the size, thickness and shape of the casting, the thickness of the casting wall can be from 0.3 to 1000 mm meters and its length varies from a few millimeters to ten meters. Also, in several types and quality, it can be from a few grams to more than 300 tons. The metal casting process is suitable for the production of parts with complex shapes, especially with complex and difficult cavities such as complex boxes and consisting of many components, valves, aircraft and ship propellers, engine cylinders, etc.
2.2.2 used in casting
The materials used in metal castings are widely available. Almost any material can be melted into liquid alloy, such as steel, all kinds of aluminum alloy, copper alloy, iron alloy, platinum alloy cast iron, etc. For those brittle alloy materials with low ductility (such as ordinary cast iron), casting is the only possible forming process. In industrial production, cast iron is the most widely used material and constitutes more than 70% of the total production.
3. 3. Metal mixtures are of particular accuracy
Under normal conditions, metal castings have a more accurate size than conventional forgings and welded parts.
✔️ 4. Its low cost
The overall economic performance, energy, consumption of casting materials is less than other methods of metal formation. Metal castings are at most 40-80% of the quality in general machinery, while the manufacturing cost is only 25-30% of the total cost of the machine.
✔️ The reasons for the low cost of casting
Production methods are flexible, mass production can be organized as mechanized production.
Waste and old metal materials and renewable resources are used.
Compared to forging, metal casting consumes less electricity.
Casting has a certain dimensional accuracy, low cost, and saves processing time and metal materials.
The above analyzes are the most important advantages of metal castings, and they are also the main reasons for the popularity of metal castings.
