ML Line

Applications

The ML line is versatile and can be used as a manual workstation with a security cell or integrated into a system. It is suitable for complicated parts with multiple images printed in various positions as well as for applications which require a high degree of precision throughout the entire printing process (e.g. for multicoloured images with fine structures or screen printing). It’s also ideal for parallel printing on multiple parts within an injection moulding machine. The electrically powered stroke ensures optimal performance for sensitive printing processes (including printed electronics, opaque or translucent printing and printing on rough surfaces or glass).

Inkwell

Capable of printing up to seven colours using 56 mm doctoring cups, the ML line can also handle up to three colours with a maximum cup size of 160 mm. Various intermediate sizes and different cup combinations are available. The surface pressure of the magnetic doctoring cups can be increased by a pneumatic holder on request. The variant with transverse doctoring unit is used for very long print images, or for the unwinding device. If the optional microPrint Viscomat is installed, ink viscosity inside the cup is regulated automatically.

Pad positioning

The X and Y position of the pad is adjusted in 0.01 mm increments through the display and controlled by linear motors. The pad stroke can either be executed pneumatically or electrically using a servomotor and spindles. In the case of a pneumatic stroke, the speed is controlled by a throttle. The electric pad stroke offers different speeds on the up and down stroke for every single step – up to and including setting the length of time the pad remains in contact with the print object. It is possible to use up to five selective pads. The angle is set mechanically at the cliché holder.

Parts handling

Standard models feature two toolport interfaces for connecting simple handling devices (such as vacuum boxes, parts sensors, clamps, pneumatic shuttle or rotation, or controlled jets of ionised air). The ML line can be optionally fitted with rotation on one or two axes or a simple shuttle for integrating any pre- or post-treatment devices, camera controls or robotic loaders.

Operation, software and interface

peration is performed through the graphic, multicoloured touchscreen display. Printing procedures can be programmed in simple steps with the help of a user-friendly visual representation. The ML line features a galvanically isolated digital interface and an Ethernet connection for updates and back-ups of order data. Optional system communication enhancements include Profinet, Ethernet/IP or EtherCAT. To integrate operational data recording, an optional OPC UA interface is available.

Accessories

For standalone operation within a system, we recommend at least pad cleaning control and the Viscomat. For top requirements regarding product safety, filling level gauges for both units may be added, as well as additional sensors for temperature and humidity. Cliché cooling is available to minimise temperature effects on colour transfer time and on the ink’s pot life. Safety cells can be specially designed for sitting or standing workstations. These can be equipped with an additional rotary indexing table and a laminar flow to minimise dust.
