Hot forging is a metalworking process that involves heating metal to a high temperature and then shaping it using compressive forces. This process improves the material's mechanical properties, making it stronger and more durable. Hot forging is commonly used to produce complex-shaped components for industries such as automotive, aerospace, and machinery. It offers advantages like better material properties, reduced porosity, and enhanced grain structure. Overall, hot forging is a crucial manufacturing technique for creating high-quality and reliable metal parts.
