Hot-pressed refers to a manufacturing process where materials, often metals or ceramics, are shaped and solidified using heat and pressure. In this method, the material is heated to a high temperature and then compressed in a mold. This combination of heat and pressure helps to eliminate air pockets and improve the density and strength of the final product, making it more durable. This technique is commonly used in industries like aerospace and automotive to create components that require high performance and reliability. For example, ceramic parts made through hot-pressing can withstand extreme temperatures, making them ideal for use in jet engines or brake systems.
