Casting – Advantages, Disadvantages and Product Classification

Advantages: 1.It can produce parts with complex shapes, especially blanks with complex internal cavities. 2.It has wide adaptability – all metal materials commonly used in industry can be cast, with weights ranging from a few grams to several hundred tons. 3.Raw materials are widely available and low-cost, such as scrap steel, waste parts, and metal shavings. 4.The shape and size of castings are very close to those of finished parts, which reduces the amount of cutting and belongs to non-cutting processing. 5.It is widely used – castings account for 40%~70% of the weight in agricultural machinery and 70%~80% of the weight in machine tools.

Technical Requirements for Precision Casting

For example, in the case of sand mold precision casting, factories engaged in mass production should create conditions to adopt technologically advanced molding and core-making methods. The production lines equipped with old-fashioned jolting or jolt-squeezing molding machines have low productivity, high labor intensity for workers, and excessive noise, which fail to meet the requirements of mass production and should be gradually renovated.

The Five Major Elements of Gray Iron Castings

Whether the material of gray iron castings, large-scale iron castings, and machine tool castings is qualified mainly depends on whether the five major elements in the casting material meet the indicators. The conventional elements include five types: carbon (C), sulfur (S), phosphorus (P), manganese (Mn), and silicon (Si).
