Mixing, Coloration, Foaming

With the use of "high-end" steel mixing elements, hotmelt can be mixed in-line as efficiently as possible. Depending on the material properties and requirements, the mixing elements are installed directly on the melting plate or in a multi dosing head.

e.g. in the hotmelt mixing head, HMM with 4-fold dosing pump for two different reactive hotmelt and 1x colour for precise, speed-dependent robot application.

For very demanding applications (e.g. extreme differences in viscosity), a dynamic mixing head is used for temperatures up to 200°C.

Special color is added in quantities of 0.5 to 3%, usually with a static mixer (color mixer – FM). Ideally, the color is added as close as possible to the nozzle to reduce waste during color change.

Up to 100–800% (adhesive dependent) Inert gas (mostly N2) in the form of small, compressed air bubbles is homogeneously mixed into the pressurized hotmelt in a controlled dosing and mixing unit (dynamic). Those expand after the nozzle outlet to a foamed bead. Not only can adhesive be saved, but depending on the material, greater flexibility of the glue joint or better insulation values can be achieved. Our systems are also suitable for reactive and medium viscous hotmelt.
