Continuous and precise metering and mixing of adhesives and sealants
When processing adhesives and sealants, as well as epoxy resin and silicone, continuous metering is necessary for certain applications. Metering systems with progressive cavity pumps are suitable for this. These work based on the volumetric metering principle, meaning that they enable highly precise metering of the material quantity. DOPAG offers two metering systems with progressive cavity pumps: -rotordis for processing single-component materials -rotormix for metering and mixing mutli-component material Progressive cavity pumps work with no pulsation. Consisting of two components, the stator-rotor combination is the heart of the progressive cavity pump. This is a volumetric metering system that is sealed leak-free. It conveys the material continuously without any restrictions on…

Reliable metering technology for the production of household appliances
The production of modern household appliances for the global market requires stable, automated production processes. Metering and mixing technology is a key part of almost all production steps in the household appliance industry. The various components are bonded, sealed, greased or potted during the production process. For all applications involved in the production of dishwashers, ceramic hobs, ovens, refrigerators or small appliances, DOPAG provides the specially developed technology required. Single and dual-component materials are processed, including polyurethane, epoxy, silicone and lubricants. ‚All of our metering and mixing systems are adapted to our customers’ specific requirements and are individually configured, says Christian Ostermann, Director Sales for the DACH region at DOPAG.…

New online process monitoring for dispensing systems and metering components
The components of metering and mixing systems are subject to high demands and constant wear during ongoing production processes. However, online monitoring of machine status has only been possible to a limited extent until now, as there are a large number of different types of applications, parameters and polymer materials in relation to greasing, bonding, sealing and potting. Reliable assessments of historical operating data and conclusions regarding maintenance intervals and service life of components have therefore been quite limited to this point. With the brand-new LifeCycleLogger 4.0 from DOPAG, plant operators, service staff and, of course, DOPAG, as the manufacturer, now have detailed information regarding all process parameters and the…

DynamicLine from DOPAG enables efficient series production for bonding and gasketing applications with a single system
The series production of control cabinets requires high cost-effectiveness and efficiency, like all production processes. Individual work processes need to be integrated smoothly into the overall production process and offer optimisation benefits. In addition, given the current increase in raw material prices, cost savings need to be made. DOPAG has planned a partially automated system which will meet these requirements for a leading European manufacturer of control cabinets. The dynamicLine metering and mixing system is suitable for two applications required in the production of control cabinets – gasketing and bonding. Processing highly reactive materials reliably During production, a polyurethane (PU) gasket needs to be applied to the control cabinet doors.…

Dispensing system for bonding the world’s first retractable solar roof
Parking spaces, logistics areas and waste water treatment plants require a lot of space. Why not make efficient use of this space? This is what the Swiss start-up dhp technology thought when it constructed the world’s first retractable solar roof. The individual modules are manufactured with dispensing technology from DOPAG. The world’s first patented retractable solar roof was developed under the name Horizon by dhp technology AG. The car park roofing is one of the latest projects from the young Swiss company based in Zizers in the canton of Graubünden. This all began with the roofing of wastewater treatment plants. In 2018, the first model went into operation in the…

Reliable processing of thermally conductive materials
Electromobility is currently one of the strongest growth industries. Electric cars, scooters and bikes are being manufactured in increasing numbers. Demand is also increasing in terms of mobile energy. There are more and more devices featuring rechargeable batteries, such as power tools, household appliances and medical products. Thermally conductive materials are processed during production. These materials typically contain a large amount of filler to enable them to fulfil their role, i.e. to conduct heat. DOPAG developed and created the vectomix TC metering and mixing system specially for processing these types of filled, abrasive materials. The dispensing system is equipped with components made of wear-resistant materials. They are specially designed for…
