Material Selection and Properties
Precision casting provides a wide range of material options for mechanical parts. Casting allows for the use of various alloys such as stainless steels, nickel - based alloys, and aluminum alloys. For instance, in the production of parts for high - temperature applications, nickel - based alloys can be precision - cast. These alloys have excellent heat resistance and mechanical strength, making them suitable for components in gas turbines and industrial furnaces.
The casting process also enables the control of material microstructure. By carefully controlling the cooling rate and alloy composition during casting, the mechanical properties of the part such as hardness, toughness, and ductility can be optimized. For example, in the casting of crankshafts, the microstructure can be adjusted to achieve the desired combination of strength and fatigue resistance.
Dimensional Accuracy
Precision casting is renowned for its ability to achieve high dimensional accuracy. Tight tolerances are crucial for mechanical parts, especially when they need to fit together precisely in an assembly. For example, in the automotive industry, engine components such as pistons and cylinder heads need to have precise dimensions to ensure proper engine performance.
The casting molds used in precision casting are designed with high precision. Advanced techniques such as investment casting can produce parts with tolerances as low as ±0.1 mm. This level of accuracy reduces the need for extensive post - machining operations, saving time and cost while maintaining the integrity of the part's design.
