Muototeräistyksissä

Muototeräistyksissä is a Finnish term that translates to "mold tempering" or "mold annealing" in English. It refers to a heat treatment process applied to metal molds, primarily used in plastic injection molding and other forming processes. The purpose of muototeräistyksissä is to relieve internal stresses that have accumulated in the mold material during its manufacturing, such as machining and welding, or during its operational use.

The process typically involves heating the mold to a specific temperature, holding it at that temperature for a defined period, and then cooling it slowly. The exact temperature and holding time depend on the type of steel used for the mold and the extent of the stresses to be relieved. Slow cooling is crucial to prevent the reintroduction of new stresses.

By reducing internal stresses, muototeräistyksissä enhances the dimensional stability of the mold. This leads to improved accuracy and consistency in the manufactured parts. It also helps to prevent premature failure of the mold, such as cracking or warping, thereby extending its service life and reducing maintenance costs. This heat treatment is a critical step in ensuring the reliability and efficiency of mold operations in various industrial manufacturing settings.
