Kuumamuotoilulla

Kuumamuotoilulla, known in English as hot forming or hot working, refers to a metalworking process where a metal workpiece is shaped at a temperature above its recrystallization point. This means the metal is heated to a high enough temperature that it becomes more ductile and easier to deform. The process typically involves using dies or molds to press, bend, forge, or extrude the heated metal into a desired shape.

The primary advantage of hot forming is that it requires significantly less force to deform the metal compared to cold forming. This is because the elevated temperature reduces the metal's yield strength and increases its ductility, allowing for larger deformations without fracturing. Furthermore, hot forming can refine the grain structure of the metal, leading to improved mechanical properties such as toughness and strength in the final product. It is also effective in eliminating internal defects and creating complex shapes that might be difficult or impossible to achieve through other methods. Common applications include the manufacturing of automotive parts, aerospace components, tools, and various industrial equipment. The specific temperature used depends on the type of metal being worked.
