What defines forged shears in terms of their manufacturing process?

1. Injection molding

2. Stamping

3. Hammering or compression

4. Machining

The correct answer is: Hammering or compression

Forged shears are defined by a manufacturing process that involves hammering or compression, which shapes the metal into the desired form while also enhancing its structural integrity. During this process, the metal is typically heated to make it more malleable, and then it is subjected to mechanical force, either through hammering or pressing. This not only results in a strong and durable product with improved hardness but also refines the grain structure of the metal. In contrast, other methods, such as injection molding, typically involve melting materials and injecting them into molds, which is not applicable to metal shears. Stamping involves cutting or shaping material using dies, which may not provide the density and durability found in forged products. Machining, while also a common process for producing tools, involves removing material from a solid block, potentially leading to a less efficient structure than the one achieved through forging. Thus, the forging process is pivotal in ensuring the quality and performance of shears in professional settings.
