Gasketing
Dispensing system for PU and silicone foam seals
Foam sealing is a process in which a PU or silicone foam seal is automatically applied to components. It protects electronics from dirt, moisture and dust, for example inside control cabinets or in automotive components.
Process-stable metering, mixing and dispensing of PU or silicone foam gaskets
Users face several challenges: On the one hand, machines offer an excellent solution for switching from manual work to machine operation. On the other hand, materials are becoming increasingly complex and it requires dispensing technology that processes these materials reliably and to a high standard of quality.
Gasketing at a new level
The processing of highly reactive materials requires a high level of accuracy, reliability and precision. Sealing foams, adhesives and casting compounds need to be processed more and more quickly today.
Technology for automated application of foam seals
The dynamicLine from DOPAG offers a solution that meets all the requirements relating to foam sealing. With its dynamic mixing system, it processes highly reactive, two-component materials based on PU and silicone with high precision. The foam seal is then applied to the component by a linear robot.
The advantages of automated application of foam gaskets
- Foam sealings in reproducible quality
- Programmed overlap, no coupling or joints
- Width, height and hardness of the gasket are individually adjustable
- High process stability
- Short cycle times
- Less material waste
- Saves up to 90% of production costs compared to manual application of foam gaskets
- Completely automated system
- Indvidualised system configuration

For perfectionists
Formed-in-place foam gasket (FIPFG)
In the case of a formed-in-place foam gasket (FIPFG), a highly reactive material is applied to a component automatically. The material, a polyurethane or a silicone, is metered and mixed using a dynamic mixing system and then applied along a contour. Following a reaction time defined by the material formulation, the material foams up and adheres to the component. Benefit of dynamicLine: the dynamic mixing system specially processes materials that are highly reactive in terms of the reaction process and mixing ratio. The material can be processed properly over a long period of time, thus keeping the service life as long as possible. The longer the service life of the material in the mixing head, the more components that can be produced in succession.
Formed-in-place gasket (FIPG)
Thanks to its flexibility, dynamicLine is also suitable for the formed-in-place gasket (FIPG). Non-foaming, highly reactive adhesive systems that cannot be processed using a static mixing system are metered, mixed and applied here. All applications can be carried out quickly and efficiently with dynamicLine. The compact system design also saves space – a highly efficient solution which offers flexibility and ensures optimal results.
