FIP(F)G – the automated production technology for foam sealing, potting and gluing

With Formed In-Place (Foam) Gasket Technology – FIP(F)G for short – a process is available, which in many cases further optimises the production processes of foam seals, gluing and potting – technologically and economically speaking. Designed according to your requirements, Sonderhoff solutions ensure high process reliability and quality. In this way we create the conditions for perfect seal, glue and potting quality for your parts. Damp, Dust & Co. keep out!

The industry is forever on the search for the most efficient production methods. That is why automation is a central topic, as much for plastic and metal processing as for upstream and downstream processes. For it is the global pressure of costs and competition that demands slick and swift production processes in the main.

Here, the Sonderhoff enterprise group is at your service as a technological leader and process specialist for the foam sealing, gluing and potting of your components.

As experts in FIP(F)G, a technology that has become successfully established within the industry, we are the go-to specialists for the most diverse range of implementations and requirements, and to find the right level of automation for your process.

For FIP(F)G processes, we offer you not only the right material systems – by Sonderhoff Chemicals – but also the two- and multiple-component mixing and dispensing systems by Sonderhoff Engineering. We distinguish here between two different FIP(F)G technologies: the classic low-pressure technology for mixed-cell polyurethane foam and the newly introduced medium-pressure technology for its closed-cell cousin.

The FIP(F)G process is at the same time the technological starting point for a rich diversity of specialist processes, such as foam moulding, dam & fill, doming, rotational moulding, spraying or roller application.

The three fundamental processes:

Foam sealing

Foam sealing

Conventional seals like the O-ring are ready-made parts which are applied or glued to the sealing lip. With foam sealing, however, the seal only comes into being in location; it is “formed in place”.

To this end, a fluid-to-thixotropic sealant is applied to the sealing lip, which only then reacts to form a finished, resilient seal firmly attached to the substrate. In this way, new possibilities open up as regards, for example, seal geometry or automation, and also the properties imbued in the material through the specific formulation of its recipe...

Potting

Potting

While seals, as a rule, serve to enclose a housing containing the material in need of protection, potting is applied directly to the surface of such materials.

This has advantages, for example, with very small components, which would require an accordingly miniaturised housing, with chips and circuit boards, where copy protection can be added, or with cable harnesses, where flexibility must be maintained.

All these applications set their own requirements of the potting material and the method of application.

Gluing

Gluing

Glues are the rivets of the 21st century.

If rivets revolutionised the art of construction with the Eiffel Tower, today it is modern adhesives that are offering all-new possibilities. Previously irreconcilable materials can now be fused, product designs simplified and a good deal of weight saved at the same time. The opportunities are practically limitless.

With the right expertise, product ideas can now be brought to fruition that would have been technically impossible before.
