Dispensing technology for all e-mobility applications from a single source

DOPAG offers efficient solutions for bonding, gasketing and potting and will be presenting them at the Battery Show 2022 in the US

PCBs and plug-in connections are potted, control unit housings are bonded and sealed - metering and mixing technology plays a central role in the field of electromobility. It is used in many production steps. DOPAG offers solutions for all applications from a single source. Adhesives and sealants, sealing foams, potting compounds or thermally conductive materials can be processed reliably with systems from DOPAG.

At the Battery Show in Novi, Michigan, USA, customers can obtain information directly from DOPAG experts about solutions for electromobility. The trade fair begins on 13 and ends on 15 September. The DOPAG team has the stand number 1347.

Optimum protection for components with PU gaskets
PU gaskets protect electronic parts, for example, the housings of control and distribution units from dust and moisture. The PU gaskets are applied automatically with the dynamicLine from DOPAG. Its dynamic mixing head dispenses and mixes polymeric reactive materials reliably and reproducibly. Thanks to the automated material application, the PU gasket adapt to the component, have no disadvantageous and possibly leaky coupling points and adhere firmly to the component. With its high quality, the soft foam seal provides long-lasting protection.

Processing thermally conductive materials
In the field of electromobility, thermal energy must be evenly distributed and dissipated on numerous components in order to protect neighbouring components or the functional assembly itself from it. In addition, sensitive components are sealed and thus protected from environmental influences. Among other things, thermally conductive materials are processed during production. These materials usually contain a high proportion of fillers in order to fulfil their task - the dissipation of heat. DOPAG has developed and designed the vectomix TC metering and mixing system especially for processing such filled and abrasive materials. It has components made of wear-resistant materials that are specially designed for the abrasive behaviour of heat-conducting materials. This protects them from excessive wear and ensures consistently reliable processing and later also high quality and durability of the components.

DOPAG accompanies customers from the very beginning throughout the entire course of the project, carries out trials in its own technical centre and works together with the customer to develop the solution that is precisely tailored to their requirements.
