The glue dosing system is a simple and reliable system that allows the application of a certain amount of glue on boxes, cartons, trays, etc. The expulsion of the glue is controlled by an electro-pneumatic valve, controlled by the operator with a pedal or button. The amount of glue to be dispensed can be easily adjusted using a timer. Thanks to the valve that discharges the excess air, it is also possible to apply just one glue point without risking leaking from the gluing machine. The gluing machines are supplied with about 3 meters of compressed air hose. The length of the tube can be changed during the order.

The corrugated board industry traditionally relies on corn starch and wheat starch. AGRANA corn and wheat starches are characterised by excellent adhesion and rapid initial tack, which is particularly important at high machine operating speeds.

Spray gluing machine for professional use, it allows the application of hot melt adhesives in granules or stick diameter 43 mm. Thanks to special nozzle nebulizes the glue and does not create thickness. Suitable for the bonding of large surfaces. The closed fusion system container allows to have in a few seconds a large amount of molten adhesive to a fast dispensing. The temperature is electronically controlled by an LCD display, which guarantees a particular precision and ease of use. With the melting tank (optional) you can heat the glue before use, making the use of the gluing machine faster and cheaper.

The ViscoDuo-VM 2-component dispenser is a valveless dosing system for static mixing based on the proven progressive cavity technology and thanks to its purely volumetric precise dosing principle, is ideally suited for high-precision dosing tasks. Built according to modular structure, a configuration of the 2-component dosing systems as well as maintenance and part exchange at module level is possible. The material components are mixed downstream of the mixing head only in the mixing tube to prevent material hardening in the system components of the mixing head. Your advantages: - repeatable dosing volume even with viscosity and density fluctuations - Processing of low to high viscosity materials with low to very high filler content - Dispenser and mixing head segments can be combined in size due to modularity - standard equipment with dead space-free integrated dosing pressure sensors for online process monitoring - simple assembly/disassembly of the components
