2024 07 21 Casting and forging are two important and complementary processes in the metalworking industry. They have significant differences in raw material handling, process methods, product characteristics, and application ranges. Casting involves melting metal and pouring it into a mold to cool and solidify into shape, making it suitable for producing complex shapes, large quantities, and low-cost parts. Forging, on the other hand, uses pressure to deform solid metal plastically, ideal for manufacturing high-strength, high-precision, and relatively simple-shaped components. This article will delve into the differences between these two processes, their respective advantages, and factors to consider when choosing between them.
