CombiJet Marking

The CombiJet Paint Marking System provides short marking cycle times at high marking speeds, thus meeting the increasing demand for marking at high velocities and with high resolution. The CombiJet is suitable for all steel products.
The CombiJet Paint Marking System is an electro-magnetically activated marking system, which requires little maintenance to operate day in and day out.
The markings may include alphanumeric characters, customer brand & ID, logos, special characters, classification symbols as well as machine-readable codes. Furthermore, the Magnemag software tool for font generation, MagFont, allows generation of e.g. Cyrillic and Chinese characters and any other type of complex character mix.

CombiJet Marking Technology

The CombiJet Marking Technology is Magnemag’s most recent development in our effort to provide the industry with superior marking technologies, which will set the industry standard for paint marking in the future.
In comparison to conventional paint marking technology the CombiJet Marking Technology does not require a needle to control the paint flow. This is made possible by electro-magnet pulse activation of the individual nozzles; allowing the small amount of paint required for each dot to be metered into the atomizing air and subsequently be applied to the surface as a paint dot.

The paint is circulated through the marking section to prevent internal clogging. The circulation system for paint has a build in on/off valve which will stop the flow during marking, providing for the same constant pressure at all nozzles in all marking sections. Between the marking sequences, when the valve is open, the flow is high preventing clogging and sedimentation of pigments in the paint system. As the consumption of air for atomizing is greatly reduced compared to conventional marking, the overspray is also greatly reduced, resulting in less requirement for cleaning.

Easy Maintenance
The CombiJet Marking Section is designed to be maintenance free and is a so called “Plug & Play” solution. The paint & air nozzles are located inside the manifold to prevent damage during handling and maintenance. No adjustment on the marking section is required. Once the paint viscosity and paint/air pressure has been adjusted, the dot size is exclusively controlled by the electrical activation time. For easy and quick connection the CombiJet Marking Section is equipped with push-on fittings for paint, solvent and air supplies.

Automatic Cleaning and Shut Down (Bypass Valve Block)
MAGNEMAG has developed a “Bypass Valve Block” that is built into the CombiJet Marking Head. The valve block is equipped with a series of valves controlling the distribution of paint forward/return, air and solvent to the marking section. Besides from distributing media, the valve block also controls the cleaning sequence for the CombiJet Marking Section. The cleaning sequence automatically bypasses the paint supply, drains the marking section for paint and cleans it with solvent and air. This feature is a big improvement in terms of easy and time saving maintenance.

As the marking section can automatically be cleaned and drained for paint it can easily be removed /replaced and taken out for maintenance immediately without having any leftover paint in the system. The system is controlled from the small HMI panel mounted in the Control Unit.
The cleaning function can either be activated manually or automatically; the setup parameters determines its mode of operation. In automatic mode there are two cleaning methods: “Cleaning after Marking” and “Interval Cleaning”.
