A press connection is a connection between two parts that takes advantage of the friction between these two parts. For example, the thermal expansion of materials can be exploited: Most materials expand when they are heated. For example, two parts that have been cooled and put together in this way can be firmly connected after they have reached room temperature, since they have become firmly wedged by the expansion. This is also called cold stretching . In contrast, if one of the parts is heated before it is assembled with another part, this is called shrinking .
