Fil­ters

Glue fil­ters have a very impor­tant role in adhe­sive sys­tems. They stop dirt that could clog the noz­zle and stop the appli­ca­tion of glue to the joined mate­ri­als. We fil­ter the glue from the tank using the appro­pri­ate gra­da­tion main fil­ter and in the next stage we fil­ter the glue after the hoses before the guns/​heads. The fil­ter gra­da­tion is adjusted to the noz­zle diameter.

Noz­zle

The size of the noz­zle open­ing deter­mines the pres­sure that is nec­es­sary to apply a cer­tain amount of glue at a given rate time. The noz­zle diam­e­ter should be such that the appro­pri­ate amount of glue can be applied required a pres­sure greater than 30 – 40 bar. This applies to most track appli­ca­tions. There­fore, it is impor­tant that the glue noz­zle has the appro­pri­ate cap­il­lary length and diameter.

Heated hose

Heated hose used to melt and main­tain a con­stant, ele­vated tem­per­a­ture of the glue between the melter and the glue apply­ing head.

Gear pumps

We use gear pumps mainly for con­tin­u­ous appli­ca­tions. They ensure con­stant adhe­sive pres­sure dur­ing appli­ca­tion. The pumps dif­fer in size adapted to the demand for hot melt glue.

Pis­ton pumps

Pis­ton pumps – pneu­matic, used mainly in the pack­ag­ing indus­try. Pumps, depend­ing on the device, are char­ac­ter­ized by a ratio, i.e. the amount of air pres­sure given to the pump trans­lates into the glue pres­sure, usu­ally 12:1 or 14:1 pumps, i.e. 1 bar of air gives 12 or 14 bars of glue at the pump output.

Glue mod­ules

Glue mod­ules are part of the gun or head for apply­ing glue. Mod­ules are con­sum­able parts, their ser­vice life is usu­ally from 40 to 100 mil­lion cycles.

Glue guns

Glue guns are the com­mon name for the last ele­ment of the glue appli­ca­tion sys­tem. Guns are divided into sin­gle– or multi-​module and elec­tric or pneu­matic. Guns can be con­fig­ured for a given application.
