FLAMING DEVICES

To print on certain surfaces (in particular, plastics such as polypropylene, polyethylene and poly-acetate) may be necessary to subject the pieces, before (pre-treatment) or after printing (post-treatment), to a flaming process. This operation promotes the adhesion of the ink and its polymerization because it eliminates the superficial greasy substances and creates a temporary modification of the material surface, increasing its surface tension. There are several types of gas flaming devices: column, for lines, flaming belt. It is possible to install burners for LPG gas of different sizes depending on the surface to be treated (60-100-130-150-200 mm); they are fitted with flame non-return valves and made according to the EC regulations in force. The automatic control device allows to set the ignition of the flame, the detection of its presence, the gas solenoid valve.
