What exactly is rivet/blind rivet technology?

GESIPA® makes it clear

Blind rivets

GESIPA® blind rivet technology has come to be an essential part of many modern industrial production processes requiring joining technology owing to its high levels of cost-effectiveness and versatility. It combines a number of advantages in one solution, providing access to the blind side in an application, reliably joining a wide range of materials with lasting effect, including more sensitive ones, and documenting the setting process where required.

Blind rivets come in a wide range of forms, materials, shapes, lengths and even colours. Depending on the application you have in mind for the blind rivet, you can choose to order a standard model for delivery straight from the GESIPA® warehouse or choose to have a blind rivet designed especially for its intended use.

GESIPA® blind rivets – terminology

A blind rivet consists of two parts: the hollow rivet and the mandrel body. The hollow rivet has a setting head and a rivet body. The setting head is located on the processing side and is available with a range of diameters and in different forms. The head variants are as follows: dome head, countersunk and large flange. The rivet body comes in different lengths that will depend on the thickness of the material to be riveted. The job of the mandrel body is to deform the rivet body. It has a predetermined breaking point, at which the mandrel body breaks off once the rivet has been deformed sufficiently. The filling section is the portion of the mandrel body that is left behind in the hollow rivet. The spent mandrel is the portion of the mandrel body that is removed from the set rivet using the blind riveting tool and disposed of.

During the setting process, the mandrel body is moved using the setting tool jaws, deforming the hollow rivet until it is firmly positioned in the component as predefined. In the end, the mandrel body breaks off at the specified point (the predetermined breaking point) and can be disposed of via the recycling system. The rest mandrel is the spent mandrel left behind in the hollow rivet and can provide an additional locking function depending on the application in question.
