A. German S.E.W. Motor powers screw rod driven screen up/down position 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 to prevent movement of substrate. 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. Patented mechanical print head guided on precision sealed linear motion bearings allows stable, vibration-free movement.
F. Squeegee and flood printing parameter settings for speed, pressure, and stroke travel distance is independently controlled by single action from the touch screen.
G. 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.
H. Print table X / Y movements via precision scaled micrometer control(s) for fine registration. Play-free registration without backlash.
I. Touch screen control of off-contact height between substrate and screen. Numerical value can be set up to accommodate substrate thickness 0 – 50 mm (0 – 2”).
J. Choice of six print functions from touch screen: flooding before the print stroke, flooding after the print stroke, higher cycle speed-flood while screen lifts to full up position, double squeegee printing mode with use of two squeegees mounted allowing printing in both directions and screen lift up to print position, twice printing mode (flood while screen lowers and the last flood when screen is in up position) and double squeegee mode with use of two squeegees to perform left print direction while right squeegee is idle and right print direction while left squeegee is idle. Includes no flood setting and print head lift for ease of sq / fl load and unload without removing for fast setup.
K. Touch screen input of printing standby height 100-300mm. This is the distance that the screen lifts up after the squeegee and flood sequence. Numeric value can be preset to stop the screen in a lower position for increase cycle speed.
L. 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.
M. Touch screen input variable and independent for print and flood stroke speed and length setting to image size. Numerical input of right print stroke start point 0-240mm and left stop point 180-330mm – AT-25PA and 280-530mm – AT-45PA 0-240mm and 280-530mm.
N. Print operating cycles: Manual setting for set up procedure, setting for foot pedal control in single cycle and automatic control with dwell timer range of time selectable from 0.2-60 seconds for substrate loading, auto-print and off-loading.
O. Productivity preset in numerical values for throughput can be changed anytime. Enter production quantity according to run length and during the run screen will indicate current yield until preset number of prints are achieved.
P. Frame loading and unloading from the front of the machine to facilitate fast setup and changeovers.
Q. Control system for compressed air supply is an oil free FRL unit to prevent oil mist pollution, applicable in clean room environment. Less air consumption, ½ HP air compressor is enough.
R. 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.
S. Front safety bar location on the print head, compliant with OSHA safety regulations.
T. Includes 4 squeegee holders and 4 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.
