Dispensing technology for automotive industry and e-mobility

Dispensing lubricants, sealing foams, adhesives and thermally conductive materials

More than 150 greasing and oiling applications and up to 300 sealing, bonding and gasketing applications are required in the production of a vehicle and making it operational. As a full-service provider, DOPAG offers solutions for all technical metering applications in the automotive industry. This also includes dispensing systems for applications in relation to bonding and sealing as well as composites. Metering and mixing technology from DOPAG can be easily integrated into highly automated production lines.

As part of e-mobility, new materials and new technologies are also being used: for instance, modern lightweight materials (composite components) or assistance systems with sophisticated sensors. All production processes for the mobility of the future make use of highly automated metering and mixing technology, with which a wide range of materials are processed and applied: from lubricants to adhesives and potting compounds to thermally conductive materials.

Applications in automotive industry and e-mobility

Metering and mixing technology for lubricants, sealing foams, adhesives and thermally conductive materials

Metering and mixing technology for electric vehicles and vehicles with combustion engines

We offer metering technology for these applications:

Greasing and oiling

Valves and pumps for lubricants

The application of lubricants ensures optimal operation and the long-term performance of mechanical, mechatronic and electronic components, such as in the case of adjustable seats, window regulators, brake systems and in transmissions. With lubriLine, DOPAG has developed a product line specially tailored to the needs of the automotive industry. Various drum and barrel pumps, metering valves, dispensing valves and components for testing and control can be put together as part of an individual system concept depending on the application. DOPAG’s high quality standards guarantee high precision, reliability and reproducibility at all times.

Gasketing

PU gaskets protect components

For the production of PU gaskets, DOPAG offers an efficient solution for automated production in the form of dynamicLine. In combination with a linear or industrial robot, gaskets can be applied to brake lights, ventilation grilles or speaker casings. Thanks to the automated application, the seals can adapt to the component, they have no coupling points and, in contrast to inserted seals, they do not need any additional adhesive tape for bonding. The system is rinsed with water, which is good for the environment, and there is practically no waste. DynamicLine is also suitable for the dynamic processing of additional polymeric reaction materials such as adhesives and potting compounds.

Bonding and sealing

Metering systems for bonding and sealing

For bonding and sealing, DOPAG offers a range of metering and mixing systems that can be tailored to the specific application. Single-component adhesives and sealants can be applied with metering and dispensing valves from DOPAG, such as in shot or bead form. For precise, reproducible processing of two-component materials, DOPAG offers a reliable piston metering system in the form of vectomix. This enables interior parts, electronic components or casing covers, for example, to be reliably bonded and sealed.

Composites

Production of composites parts

Lightweight design is used in the automotive industry whenever weight needs to be reduced. DOPAG offers a range of metering and mixing systems for the production of composite parts made from glass fibre-reinforced plastics (GRP) or carbon fibre-reinforced plastics (CRP). This includes systems for all applications relating to the production of composites, from RTM applications and filament winding to pultrusion. The metering and mixing systems compomix or eldomix would be suitable for these types of applications. They process materials based on polyurethane or epoxy resin reliably, with precise reproducibility.

Thermal interface materials

Metering of thermal interface materials

Every vehicle, whether it has a conventional or an electric drive, has numerous different electronic assemblies. Thermal energy has to be evenly distributed and discharged in a wide range of components, also in order to protect neighbouring components. The delicate components often need to be sealed up and protected from moisture. DOPAG offers special metering and mixing systems for processing of the thermal interface materials required. These are suitable for the potting of sensor electronics, such as for headlamp range control, adaptive driving systems or driver assistance systems like tiredness sensors or airbags. For the processing of thermal interface materials with a high volume of abrasive fillers, DOPAG offers a hard-wearing, reliable solution with high process reliability in the form of vectomix TC.
