Dynamic mixing head

The dynamic mixing head has a modular design and is available in three forms. Different mixingchamber sizes enable discharge capacities of 0.1 to 30 g/s. The various types of valves andmixing chambers can be combined flexibly in accordance with the required discharge quantityand material properties. This ensures an optimal relationship between the flow rate of thematerial and the application speed. Our experts determine the appropriate combination duringthe individual sampling in the DOPAG technical centre.

• Robust version for use in complex production environments with maximum accuracy
• Installation of component valves quickly and conveniently
• Processing of up to four components possible, whereby only three components can be metered simultaneously
• Easy cleaning and maintenance of mixing head and mixing systems
• Metering accuracy of better than +/– 1% (depending on the material, discharge capacity and mixing ratio)
• Recirculation of all components up to the mixing system before and after metering
• Separate control of metering valve and recirculation valve ensures high flexibility and optimisation of the application, particularly around the coupling point
• Automated material pressure adjustment for a defined target value

• Nozzle-closing system (NCS): The nozzle-closing system prevents the material from dripping and ensures seamless closure of the sealing bead.
• Careful processing of material: Practically no heat development and no premature cross-linking of material in mixing system
• Material-independent technology: Processing of all common materials for gasketing, bonding and potting. We cooperate with the leading material manufacturers in this. As an independent machine manufacturer, we come up with the perfect solution for every challenge.
• Flexible control of individual valves: Separate control of metering valve and recirculation valve ensures high flexibility and optimisation of the application, particularly around the coupling point
• High-pressure water rinsing: Environmentally friendly, cost-efficient cleaning of mixing system
• Process monitoring: All work steps are monitored during production.

The nozzle-closing system (NCS) prevents dripping at the nozzle opening. This ensures a smooth transition on the bead and prevents undesired contamination of the components. The NCS moves the drive shaft vertically in the bottom of the mixer, allowing the rotor in the chamber to position on a Teflon seal. This mechanically designed closure prevents the reactive material from being pushed out of the chamber.
