A. German S.E.W. Motor powers screw rod driven head lift and drive motor for squeegee/flood travel. Provides high cycle speed with smooth mechanical movements, low noise and accuracy.
B. Printing table surface is CNC precision milled and manufactured from high quality anodized aluminum to achieve close tolerance planarity. Honeycomb construction for rigidity, while offering powerful, heat-dissipating turbine vacuum. Suction force is adjustable for optimum substrate control and printing requirements.
C. Travel of squeegee / flood on guided precision sealed linear motion bearings, reinforced tooth belt, timing belt wheel for high rigidity and ultra-smooth high print speed transport cycles without backlash. This ultra-smooth gliding of the squeegee / flood assembly enables step-less speed change for higher production speed, smooth operation, consistent / uniform printing deposit control, less maintenance and fast operation.
D. Squeegee / flood high-park capability facilitates faster setup and changeover.
E. Pneumatic frame locking with check valves / airlock and four-sided frame holding assembly ensures rigidity and high stability.
F. Patented mechanical print head lift guided on precision sealed linear motion bearings allows stable, vibration-free movement in up/down positions.
G. Manual squeegee and flood printing settings for height up / down position, pressure, angle and manual travel for set up independently controlled by user-friendly main control panel with lighted switches. Stroke length distance is controlled by proximity switches.
H. Includes pneumatic squeegee / flood pressure equalizer control system. Fully automatic and regulated by a constant pressure control system equalized with pivot point balance for angled substrate along with snowplow skew feature for irregular print surfaces.
I. Stable pneumatic cylinders are encased around solid cast to allow consistent pressurization of squeegee and flood. After initial setup pressure regulator can be increased and decreased. For most applications suitable pressure range is 3-4 bars and the squeegee and flood both have pressure indicators to gauge incremental setting amount.
J. Screen peel-off by pneumatic lift cylinder to assist release of ink and mesh from substrate synchronized with the print stroke in the auto-mode of operation. Flood coat sequence is carried out with the frame in the horizontal position allowing a no peel flood function. This benefit offers more uniform control and evenness of ink layer over length and width of image area.
K. Peel-off height lifting point adjustable by low speed cylinder with stroke adjustment, downward speed valve, upward speed valve and stroke upward height setting.
L. Mechanical adjustment of off-contact height settings to accommodate substrate thickness 0 - 25 mm (0 - 1”).
M. Print table X / Y movements via precision scaled micrometer control(s) for fine registration. Play-free registration without backlash.
N. Choice of three print functions from touch screen: flooding before the print stroke, flooding after the print stroke and for higher cycle speeds flood while screen lifts to full up position. Includes no flood setting and print head lift for ease of sq / fl load and unload without removing for fast setup.
O. Squeegee / flood assembly is synchronized and changeover is pneumatically operated for smoother transition. Adjustable height controls, angle settings 0-30°, leveling and skew feature. Provides uniform ink deposits across the entire print area.
P. Variable and independent print and flood stroke speed and length setting to image size.
Q. Frame loading and unloading from the front of the machine to facilitate fast setup and changeovers. Frame holding rails can be unlocked from touch screen and easily adjusted to the size of the frame.
R. Control system for compressed air supply is an oil free FRL unit to prevent oil mist pollution, applicable in clean room environment.
S. Equipped with powerful turbine vacuum control to prevent movement of the substrate.
T. Emergency press plate positioned in front of print table in case substrate alignment is not in the correct position. Operator can press the plate and printing head slowly lifts up to the full upright home position allowing operator the chance to register correctly final substrate alignment. Reduces spoilage and yields more printed product.
U. Safety bars located on the print head, compliant with OSHA safety regulations.
V. Includes 3 squeegee holders and 3 flood coaters, sq. / fl clamps, pedal switch control, toolbox, tools and door key.
Additional registration pins, anti-static equipment and dripless squeegee. Others available upon request.
