CeraCon: The joy of foaming
Fun with foaming
Pre-treatment on nonpolar plastics: “Openair” plasma provides reliable adhesion even on polypropylene.
The engineering and machine construction company CeraCon is
considered today the leading manufacturer of single-component foaming
installations on the European market.
The application of our foam sealing technology comprises, amongst
others, the sealing of door locks and modules, floodlights and plug
cases, up to free-standing amplifier cases for base stations.
Before CeraCon brought the “foamply” technology as a new
single-component foaming technique onto the European market in 2001, we
had been looking for globally available and accepted automation
technology. Part of this was the search for a reliable and stable
pre-treatment method for the component parts preceding the application
of the foam seal. The task was obvious: the reliable adhesion of 1K-PUR
foam on nonpolar plastics in fully automatic installations with very
short cycle times was to be assured.
In order to reach this goal, different pre-treatment methods –
corona, flaming by gas, use of primer, and Plasmatreat’s atmospheric
plasma – were tested. Only the latter method met all requirements, and
moreover, no additional external media were necessary. The high
pre-treatment intensity of the “Openair” plasma facilitates very short
cycle times for the components, yielding a significant rationalisation
of the entire process.
The good cooperation with Plasmatreat has been lasting for several
years now, and we are glad that we can still state that the two
process-sure technologies “Openair” plasma and “Foamply” form an ideal
