Metering and mixing technology for mobile energy and batteries

Dispensing sealing foam, adhesives, thermally conductive materials and lubricants

Batteries and charging systems supply the ‘mobile energy’ for electrical tools, leisure products, medical devices and many other products. A wide variety of adhesives and sealants, sealing foams, potting materials, thermal interface materials, as well as greases and oils are used in the production of the various components. The systems used here for metering, mixing and application are an integral part of ‘mobile energy’.

Individually configurable metering and mixing technology
The production of all components necessary for the supply of this ‘mobile energy’ places significant demands on the metering technology. Batteries, current transformers, printed circuit boards and other electronic components need to be potted in order to protect them from dirt and moisture and to dissipate heat. The corresponding housings need to be bonded and sealed. DOPAG designs and supplies metering and mixing systems for all relevant production steps – from electronics potting and housing sealing to the greasing of moving parts.  DOPAG systems process one- and two-component adhesives and sealants, potting materials, lubricants and sealing foams precisely and reliably. Our engineers design the systems according to your specific needs and provide you with personal support through to commissioning and the stable production of your products.
