For over 20 years SIBILS S.A. has been using the technology required for the foam gasket sealing of parts and/or prototypes provided by subcontracting clients, always adapting ourselves to the particular needs of each and every case.
The FIPFG (Formed In Place Foam Gasket) sealing systems are applied using sophisticated contour robots with geometries that can be custom designed through numeric control computer programmes.
The exothermic process in low pressure equipment includes direct application on the component to be sealed. Using a two-component dosing-mixer machine polyurethane is injected with a dynamic mixing head through a nozzle that has a specific diameter for each application. The material which, on being deposited is in liquid form, cross-links in few minutes leaving a cord of soft foam gasket that responds to the strictest sealing standards or IP degrees, which guarantee protection against external agents like water, dust, humidity, etc.
The equipment allows us to use liquid or thixotropic foams, depending on each specific application and the geometry of the substrate to be foamed. They also allow for variations in the component mixture, which allows us to adjust the gasket hardness as per the particular specifications of each client.
This type of technology offers numerous advantages compared to other procedures or materials in the market:
- they are flexible foams with low density => low weight => much more competitive prices
- very versatile and affordable materials (high content of mineral fillers)
- products that allow for the easy automation of industrial manufacturing processes
- practically no join points
- quick drying, the gasket reacts in a few minutes and allows for quick joining and assemblies
- completely automated processes with the consequent savings in time and labour
A personalised study of the application is carried out for each client, including the programming and trials with the suitable material for each case.
Our chemical know-how and experience gained over these years mean we can give fast and efficient responses to all the received requests.
