dispensing technology – sealing

A barrier and connection in one

Sealed joints offer protection against external influences such as penetrating moisture, gases, dust, aggressive agents or temperature fluctuations. By applying, or dispensing, a fluid seal in the form of a strip of material, sensitive parts such as control devices or housings can be protected. Application, usually carried out automatically along a previously defined contour, also serves to join components if, for example, an adhesive is also applied.

In sealing, various different dispensing and potting processes are used:

Dam and fill

A thick, highly viscous material strip is placed like a dam around the component. Once it dries, potting resin or thick film paint can be poured into the dammed area.

Formed-in-place gasket (FIPG)av

This is the creation of a connection that cannot be undone. A paste-like strip of sealant is applied to the parts to be sealed which are then linked together and can no longer be separated.

Cured-in-place gasket (CIPG)

Sometimes it is also necessary to create a separable connection. Once the fluid sealant is applied, the cover is joined but can be released again for later repair purposes.
