Tiivistysmerkin

Tiivistysmerkin is a Finnish term that translates to "compression mark" or "seal mark" in English. It refers to a mark or indentation left on a surface as a result of pressure applied during a sealing or compression process. This type of mark is often indicative of a successful seal or a point of significant stress.

In manufacturing and engineering, tiivistysmerkin can be a deliberate indicator that a component has been properly assembled or tightened. For example, when a bolt is torqued to a specific value, it may leave a slight impression on the surface of the material it is pressing against. This impression serves as visual confirmation that the required torque has been applied, ensuring the integrity of the connection.

Conversely, a tiivistysmerkin can also be an unintended consequence of a process. In some cases, excessive pressure during assembly or handling can cause unwanted deformations or marks on delicate surfaces. Identifying the presence and characteristics of such marks is crucial for quality control, as they can signal potential weaknesses or defects in a product. The size, depth, and pattern of a tiivistysmerkin can provide valuable information about the forces involved and the nature of the material. Engineers and technicians often examine these marks to diagnose issues or to verify that manufacturing specifications have been met.
