MIXING / COLORATION / FOAMING

As explained under hotmelt technology, the properties of hotmelt can be changed specifically. As a leading hotmelt plant manufacturer, balti has developed unique, in-line technologies for colouring, mixing and foaming for applications up to 200°C and can now offer a wide range of new products:

  • colouring with paint
  • static or dynamic mixing and precise dosing of different hotmelt (2K or more; also reactive) or accelerators
  • foaming and application of low to medium viscosity hotmelt and sealants (also reactive) and much more

Static Mixer

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.

Dynamic Mixer

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

Coloration

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.

Foaming

Up to 100% 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.
