Today is the first time I have come to face the word "crimp" The dictionary says (among other things) * to pinch or press together (something, such as the margins of a pie crust) in order to seal* Dictionary definition Alright, I get it, a pie crust. How about if I seal a plastic package with a hot press? Is "crimp" there correct? How about a device that does this? A "crimp seal component"? (or maybe "crimping seal component?)
A crimp is usually a joint where the mechanical strength of the material holds the joint together.
The metal has been deformed so that it holds on to the wire end.
Heat-sealed plastic would not be considered a crimp, because it's not just a mechanical pressure that made the joint. Instead, heating the plastic has melted the two parts together and allowed chemical bonds to form between them.
