ESC-AT PTT

Modern semi-automatic screen printing machine

ESC-AT PTT

with metal vacuum twin tables conceived for high-precision industrial screen printing on materials such as printed circuits

screen printing machine with two sliding tables laid out with separate and individual drive for motor and belt
comfortable PLC control system with function indicator to show operating status and pre-set parameters and with touch screen for quick operation; settings can be memorized and called-out easily
shortened set-up times and job standardization
high-grade, low-maintenance linear guidings for silent and smooth machine motions
each of the two metal vacuum print tables is equipped with micrometric fine adjustment in x-y-axis for registration
adjustable high-performance vacuum function
high-precision printing head with pneumatic lift for change of screens and cleaning jobs
screen holder with pneumatic frame locking
modern, synchronized peel-off system with adjustable stroke and start timing
infinitely and separately variable squeegee and flood coater speed levels
start and stop point of the print stroke are settable in a range of 0 - 50 mm conceived with a unique skip-print function
pressure of squeegee and flood coater can be digitally adjusted; set values are indicated by pressure gauge
inclination angle of squeegee and flood coater, height and bias angle of printing head can be adjusted digitally
