Highly precise application of foam gaskets with dosing technology from DOPAG

The processing of highly reactive materials requires a high level of accuracy, reliability and precision. Material manufacturers are also adapting to the increasing digitisation and automation of production processes. Sealing foams, adhesives and casting compounds need to be processed more and more quickly today. The overall cycle times for handling, metering and application are continuously optimised. This places special demands on the metering and mixing technology. They need to offer solutions that are future-proof, efficient and flexible. New production concepts therefore need to be implemented and appropriate systems technology used.

With dynamicLine, DOPAG is offering a new, intelligent system for sealing foams as well as for adhesive and casting applications. The system is based on the new dynamic mixing head. It can be adapted with various robotic systems. Thanks to its flexibility, dynamicLine can be used in a wide range of applications, particularly for the application of foam seals.

Applications in Gasketing:

  • Seals in the control cabinet industry: doors, ventilation grilles, locks
  • Seals in the automotive industry: door modules, speakers, brake lights
  • Seals in the domestic appliances industry: ceramic hobs, sinks, etc.
  • Seals for the filter, lighting and packaging industry

dynamicLine – specialist for 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 precisely and in most cases automatically. The material, either a polyurethane or a silicone, is first 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 firmly to the component.

Benefit of dynamicLine for FIPFG: the dynamic mixing system is specially designed to process materials that are highly reactive in terms of the mixing ratio and reaction process. 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.

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.
