The SX LongLife jetting head is Robatech’s sustainable solution for the concactless application of low to medium-viscosity thermoplastic hot melt adhesives. The durable application head can be flexibly used and excels with small installation dimensions as well as precise adhesive application with perfect tear-off behavior. The insulated SX LongLife jetting head is suited for precise dot and bead application at medium to high speed. It is a further development of the Diamond series and thus compatible with most Robatech application systems. Based on that and its small installation dimensions, it is ideally suited for retrofits and systems with limited space. The application head is modular and available in different design versions and can thus be flexibly adopted to the respective application. As indicated by its name, the SX LongLife is very durable. The robust solenoid valve and the specially developed jetting element support up to 200 million operating cycles. Thanks to its variety, it can be flexibly used for different applications in diverse industries, such as the packaging and graphical industry. Advantages of the SX LongLife Jetting Head – at a Glance Durable and sustainable thanks to 200 million operating cycles Precise adhesive application with perfect tear-off behavior Flexible in the application and adhesives Reduced energy and adhesive consumption Increased operator and product safety thanks to CoolTouch insulation Constant temperature for highest adhesive quality No nozzle blockages thanks to filter in heating block Durable, Reliable, and Precise The SX LongLife is a double-acting, electro-pneumatic jetting head. The compressed air for opening and closing the jetting element is switched using the solenoid valve. The result is precise and uniform adhesive application. Thanks to the specially developed jetting element and robust solenoid valve, the head is particularly durable and achieves up to 200 million operating cycles. An integrated filter in the heating block prevents nozzle blockages and ensures reliable and durable adhesive application. In addition, nozzle protection prevents damage to the nozzle and loss of heat, which results in even better tear-off behavior. Increased Safety and Sustainability The CoolTouch insulation of the Diamond series protects the operator against burns, significantly contributing to operating safety. Reduced heat radiation additionally protects the products to be glued. The heat-resistant insulation ensures a resource-saving and sustainable production as energy and adhesive consumption is reduced significantly. Furthermore, the hot melt adhesive does not cool down anymore between melter and nozzle and is protected against drafts in the case of machines operating at very high speeds. A special protection is available for bottom-up applications with rotated application head to protect the jetting head against contaminations. This supports a longer service life and reduced maintenance. Modularity and Compatibility As part of the Diamond series, the SX LongLife is compatible with most Robatech application systems. This simplifies integration into existing machines and reduces spare part costs, as diverse components, such as filter, nozzle range, and heated hoses, are the same. The application head can be used in a variety of different design versions with selectable jetting elements and valve heads for optimum processing of diverse adhesive types. It can thus be flexibly adopted to the respective application.
