SX Diamond and SX LongLife – for durable and precise adhesive application

The jetting heads of the SX Diamond series are Robatech’s sustainable solution for contact-free coating of low to medium-viscosity thermoplastic hot melt adhesives. The durable application heads can be flexibly used and excel with small installation dimensions as well as precise adhesive application with perfect tear-off behavior.

The SX Diamond and SX LongLife are basically identical and only differ in the jetting element. The jetting heads are suited for a precise dot and bead application at medium to high speed. Based on that and its small installation dimensions, it is ideally suited for retrofits and systems with limited space. The hot melt adhesive application heads are modular and available in different design versions and can thus be flexibly adopted to the respective application. Thanks to their variety, they can be flexibly used for different applications in diverse industries, such as the packaging and graphical industry.

Advantages of the SX Diamond jetting heads – at a glance

• Cost-efficient thanks to durability with 50 resp. 200 million operating cycles
• Precise adhesive application with clean tear-off even at high speeds
• Flexible thanks to modular design
• Energy-efficient and safe thanks to CoolTouch insulation
• No nozzle blockages thanks to integrated filter
• Constant temperature for highest adhesive quality
• Optional bottom-up protection for applications from bottom to top

Durable, reliable, and precise

The specially developed jetting elements and the robust solenoid valve make the application heads particularly durable. Using the solenoid valve, the double-acting, electro-pneumatic jetting head achieves a precise and consistent adhesive application with clean tear-off behaviour. Thanks to the integrated filter in the heating block, nozzle blockage is prevented. Nozzle damage as well as heat loss are minimized through a nozzle guard. This results in even better tear-off behaviour and reduced operation interruptions.

Increased operational safety and reduced costs

The Diamond series increases operational safety with CoolTouch insulation. The jetting head insulation protects operators as well as products to be glued from heat. The heat-resistant insulation reduces energy consumption and ensures a constant adhesive temperature, even with a draft from very fast running machines. A special protection is available for bottom-up applications to protect the jetting head against contaminations. This supports a longer service life and reduced maintenance.

Thanks to the modular design, the application heads can be used in a variety of different design versions with selectable jetting elements and valve heads. This enables us to meet customer-specific production needs precisely. As part of the Diamond series, they are compatible with most Robatech application systems. This simplifies integration into existing machines and reduces spare part costs.
