Forgings involve various metalworking processes that manufacture parts with a strength more significant than other metalworking techniques. Once the metal piece is shaped during the forging process, the internal grain structure of such metal becomes uninterrupted throughout the part, producing results with exceptional reliability at high-stress points and inconceivable strength. But is this method really better than castings? Read on to find out!
Advantages of Forgings Over Castings
The flexibility of forged materials allows cost-effective production that accommodates every demand. Moreso, forging processes like open-die, closed-die, and ring rolling adapt to different production run lengths and allow for shorter lead times. While special performance castings only necessitate more expensive materials and process controls, as well as longer lead times.
Better Heat Treatment Response
According to metal manufacturers, forging provides a better response to heat treatment. Because alloy segregation can happen in castings, the melting and cooling operations must be closely monitored. This causes uneven heat treatment responses, which might impair finished product straightness. Heat treatment is more predictable with forgings, and they have superior dimensional stability.
Less Costly, More Reliable
It cannot be overemphasized that forging metals is cost-effective. Errors and imperfections in castings come in a range of shapes and sizes. Forged materials are more dependable because the proper heat treatment refines grain pattern and gives resistance, elasticity, and high strength qualities. They’re also made without the extra expenditures associated with casting’s stricter inspections and control process.
Casting metals neither produce directional strength nor grain flow. Additionally, the process cannot reduce nor eliminate the formation of some metallurgical defects. On the other hand, pre-working forge stock results in grain flow that is orientated in the directions that require the most strength. Alloy segregations, dendritic formations, and other flaws are rectified in forging.
Is Metal Forgings Right for You?
While forging outperforms casting in terms of predictable strength qualities, resulting in superior strength that can be counted on from part to part, there are instances when castings may be the better process. Contact us to find out which one is better for you!
