Because flame treatment activates the workpiece surface
The feel of plastics workpieces can be significantly optimized before coating by flame treatment with a gas burner. The process is not a heat treatment, but rather makes targeted use of the chemical effect of the gas flame.what does this mean in concrete terms?
The functional principle of flame treatment
The short-term flame treatment of the surface is carried out directly by a gas flame operated with a high excess of oxygen.this breaks molecular bonds in the surface of the substrate to be coated and at the same time binds active ions - mainly OH and COOH groups - in the flame. The originally non-polar material now contains polar groups, which measurably increase the surface energy of the treated substrate and enable the secure bonding of printing inks, paints, adhesives, etc.
The advantages of Venjakob flame treatment systems
Thanks to their modular design, flame treatment systems from Venjakob can be easily integrated into existing systems or supplied as a stand-alone solution. Flame treatment can be integrated into throughfeed systems, robot systems and spindle chain systems. At Venjakob, we focus entirely on you, your production processes and your specific application.
We are happy to advise you
We develop solutions that optimize processes and improve results - reliably, efficiently and precisely tailored to your system. We will be happy to advise you personally on individual solutions in the field of surface flame treatment.
