Fast and precise guns for hot melt applications

The Swiss multinational Robatech is a global leader in the development and production of adhesive application systems. SpeedStar™ Diamond application guns represent the utmost in speed, durability and precision.

The gluing process represents a key phase in the field of packaging and must meet diverse high standards, according to the product type. For this reason, the materials, shape and size of the packaging influence the gluing technology used.
In the confectionery sector, particularly for packaging candy and chewing gum, small folding board boxes are usually used, as in packaging chocolate products. The very small dimensions of the flaps on which the adhesive most be applied require clean and precise gluing, in order to achieve an effective presentation that meets POS (Point of Sale) marketing criteria.

Speed and durability. The jewel in the Robatech range is the ultra-high speed electro-mechanical application head SpeedStar™ Diamond, which dispenses up to 800 glue dots per second. Robatech has thus managed to combine speed with efficiency and wear resistance. Even though they can reach temperatures up to 185 °C and viscosity up to 5000mPas, Speedstar™ application guns have a very long average life span compared to traditional versions on the market. Furthermore, an innovative patented sealing concept enables electronic monitoring of operations and constant and continuous self-adjustment throughout the component’s life cycle.

Precision at top speed. The Speedstar™ series guns operate with remarkable precision, because the stroke of the shut-off pin is automatically controlled and adjusted. This is truly unique precision and accuracy, just like the application of precisely positioned and sized dots, with no need for manual adjustments. This performance is guaranteed for the gun’s entire life cycle. A further advantage is represented by the system’s significantly reduced adhesive consumption. Insulation and nozzle protection guarantee uniform temperatures, consequently enhancing performance. Nozzle blockage has been virtually eliminated with the use of an integrated filter.

Smart and economical. Also in terms of ecology and economy, the Speedstar™ guns are “a step forward”: equipped with the same special plastic coating as the Diamond SX series, they are completely insulated in order to significantly enhance their energy efficiency and protect the operator from the risk of burn injury.
The new heads also have an extremely low thickness, enabling their installation in limited spaces and the creation of multi-module guns with very compact interaxes. They are also compatible with most SX guns produced by Robatech, making possible retrofitting of existing installations. Integrated electronics control and constantly monitor the system’s correct functioning. Wear and defects are thus eliminated automatically. An integrated counter makes it possible to plan maintenance using a LED display with completely reliable status updates.
