Cured-in-place or CIP refers to an alternative type of seal. Instead of installing a solid finished part, liquid sealants are applied to components.
The curing or vulcanization of the sealing material takes place directly afterwards. The resulting CIP seals are firmly connected to a component and therefore cannot be lost. This is a disadvantage when a defective seal needs to be replaced.
#1 Definition CIP
Cured-in-place (CIP) seals are seals that are applied directly to the components to be sealed in a liquid or paste-like state and solidified there. Unlike finished parts such as O-rings, a CIP seal adheres firmly to a sealing surface.
#2 CIP applications
Cured-in-place seals can be applied to components by robots in highly automated processes. The application is correspondingly efficient in the production of large batch sizes. Sealing tasks that require a high degree of geometric freedom benefit in particular from the ease of assembly.
This means that the liquid cured-in-place sealant can also be applied to irregularly shaped components. Examples of applications include housing covers and radiator seals.
