1K glueLine SOLUTIONS FOR THE APPLICATION OF 1K ADHESIVES AND SEALANTS

Metering 1K materials Industrial application of adhesives and sealants Bonding and sealing LED lights DOPAG single-component systems convey media such as adhesives, sealants, greases and oils with high precision from their original containers to the point of application, where the material is applied to the workpiece either in shot form or continuously in bead form. The systems are fitted with gear, piston or progressive cavity pump, depending on requirements. Provided the medium is fluid or has low viscosity, single-component materials can be processed by means of a material pressure tank....

Products for the entire process

Reliable processing of adhesives To ensure proper metering, it is important that adhesives are conveyed efficiently and without air any pockets (air bubbles). Only through continuous, reliable material supply can optimal metering results be ensured. Depending on the material properties, process and container size, different supply systems may be chosen. DOPAG’s product range offers a comprehensive range of solutions for this. This includes drum and barrel pumps as well as pressure tanks. DOPAG uses established technology in all of its systems – gear, piston or progressive cavity pump....

Pumps for adhesives and sealants Efficient processing of single-component materials DOPAG developed the drum pumps in the glueLine product range especially for feeding adhesives and sealants. The reliable design combined with the high level of user-friendliness allow for worry-free everyday production operations. With the glueLine, DOPAG offers drum pumps for processing medium to high-viscosity materials. In addition to lubricants, they feed adhesives, sealants, polyurethanes and silicones with viscosities of up to 5.0 million mPas directly and precisely from the original container. Thanks...

Refill units To ensure uninterrupted production, automated refilling of the material pressure tanks is essential. DOPAG offers various compact refill units for this purpose. The fill level probe in the material pressure tanks enables refill- ing to be started automatically from a defined material quantity. This ensures that there is always sufficient conditioned material available for production and machine downtime is avoided. Media with viscosities ranging from highly fluid to approx. 80,000 mPas can be conveyed directly from pressure vessels by means of compressed air and then applied....

Material pressure regulators reduce the pressure of the material being conveyed down to the necessary working pressure, A material pressure regulator with a diaphragm is available for abrasive or reactive materials. Material pressure regulators of this type are ideally used for the processing of reactive, moisture-sensitive, abrasive media (ball/seat design made from hard metal), such as epoxy resin, polyurethane and various other materials. The spring chamber is sealed by means of a diaphragm. Technical specifications material pressure regulator with diaphragm Other versions available on...

Metering and application Maximum precision for your applications DOPAG · GLUELINE · 15 GLUELINE Metering and dispensing valves from DOPAG meet all the criteria required for optimal metering results – high precision, excellent reproducibility and high quality standards. DOPAG offers different valve types with two operating principles. Needle metering valves meter volumetrically (dot application). In each metering cycle, the contents of the metering chamber are discharged, triggered by a signal. The benefits of this are high repeatability and flexibility thanks to adjustable volumes. In the...

Gear metering pump Metering materials continuously and precisely Gear metering pumps from DOPAG offer all the features that are required in industry today. They meter a wide range of materials, including adhesives, sealants and lubricants, continuously and with consistently high precision. They are also designed in such a way that they are extremely robust, have a high level of efficiency and are practically pulsation-free. Gear metering pumps are extremely versatile. Each version is available with different pump clearances, making them suitable for metering low to high-viscosity as well as...

Piston metering units are used for processing 1K media, especially when short cycle times are required. All that is required is appropriate material supply and a metering calculator. The material is discharged in shot form at a freely configurable discharge rate or without interruption using a double piston system, e.g. in bead form. Different sizes are available depending on the requirements of the application. Combing two piston metering units together also enables 2K applications with this system. It is powered by a servo motor, with a spindle converting the rotational motion into linear...

Progressive cavity pump Continuous metering of abrasive materials The progressive cavity pump is a high-precision volumetric metering system that operates continuously and pulsation-free. The rotational motion of the eccentric screw ensures highly precise, constant metering, par- ticularly in the case of small output rates from 0.1 ml/ min. The special rotor-stator combination prevents excessive wear when processing abrasive materials. This guarantees a long service life and high cost-efficiency. Thanks to progressive cavity pump technology, liquids and pastes with up to 60% filler content...

Needle metering valves Diaphragm dispensing valves The needle metering valve works according to the volumetric metering principle, application is carried out in shots. The metering quantity is fixed by means of a stop screw. This ensures extremely high repeatability, reproducibility and process reliability at all times. The same valve can be used for different metering quantities and end products. This series features a unique high-pressure membrane design. The drive and metering element are hermetically sealed via a high-pressure membrane and the parts that come into contact with the...
