Grafica Flextronica takes pride in introducing the finest, most flexible range of trouble free flatbed large format screen printing machine. "LARGE FORMAT SCREEN PRINTING MACHINE" is easy to set up, easy to control, heavy duty and durable construction gives maximum stability at full production speed with top-quality prints and with accuracy required for high quality screen printing. Squeegee head on solid steel shaft with linear slide motion give accurate and vibration free squeegee movement. For easy, faster, accurate and convenient material feeding vacuum bed (in/out) movement is provided. Moreover, it also increases the safety of the operator. "LARGE FORMAT SCREEN PRINTING MACHINE" is designed with outstanding features - your benefits. Fast set up - reliable production : An important factor necessary to achieve high productivity is fast set up times. "LARGE FORMAT SCREEN PRINTING MACHINE" is designed for fast and easy set-up. The machine is designed for easy control & to minimize down time and keep the machine fully operational at all times.
 
Standard Features :
 
  • Auto take-off system.
  • Fully adjustable squeegee and flood have synchronized vertical movement, pneumatically operated. Squeegee pressure and angle is fully adjustable. Perfect prints result with accurate squeegee pressure for uniform deposit across the entire printing area. Calibrated air pressure regulator unit with meter.
  • Adjustable squeegee & flood stroke via two sliding sensors located on top of the machine allow an easy and quick adjustment for squeegee & flood stroke length.
  • Adjustable squeegee & flood speed via AC geared motor (pre-lubricated) coupled with AC frequency inverter (sensor less vector control inverter to maintain constant torque and constant speed). This system offers the possibility of infinite variable and independent print and flood speeds.
  • Adjustable squeegee skew angle.
  • Heavy duty extruded squeegee holder gives equal pressure ensures even ink thickness all over the printing area.
  • Special aluminum extruded flood bar designed to give good ink release all over the screen. This helps reduce ink thickness and increase the quality of fine-lines and halftone printing, especially when printing with process color UV inks where minimum ink thickness is required for better print quality.
  • Honey comb vacuum bed heavy duty with stainless steel top, perfectly flat and rigid vacuum base.
  • Accurate printing table movement (In/Out) on guide rails for easy loading of print material. It is also increases safety for the operator.
  • Four post pillar type for parallel screen frame lifting to avoid ink to split all over the screen. Up/down movement control by ac geared motor with ac variable frequency inverter (sensor less vector control inverter to maintain constant torque and constant speed).
  • Front frame loading reduces setup and job change over time also make easier for the operator to handle such large frames.
  • Three operating cycles automatic with dwell timer, single cycle and manual.
  • Independent motors for printing / vacuum / table movement & parallel screen frame lifting.
  • Safety bar to avoid accidents.
  • Micro registration for frame movement assures accuracy with 3-point control to easily and quickly adjust to copy registration.
  • Mechanical frame locking ensure proper tightening of frame while printing.
  • Squeegee pressure equalizer for perfect print result & a pneumatic squeegee pressure equalizing system can achieve accurate repeatable ink deposit. This device which uses pneumatic pressure to equalize squeegee pressure along the squeegee rubber all over the print area.
  • Cycle Counter to check the print runs with resetting option.
  • Two print cycles i.e. print and flood or flood and print.
  • Heavy duty and durable construction ensures vibration free operation and accurate printing at full production speed.
  • Adjustable peel off system with variable timer ensures good & sharp print results.
  • Castor wheel for easy mobility.
  • Man machine interface with programmable logical controller.
  • Soft touch keyboard.
  • Two lines LCD display.
  • User friendly operating panel.
  • Multiple printing strokes with flood without flood. This feature allows operator to program the cycle for printing more than one time on same object with flood or without flooding screen with ink after every print cycle. Print cycle is programmable from 1 to 9.
  • Flood options this feature allows operator to program flood option i.e. flood screen after every 3 print cycle or not to flood the screen after 3 print cycle. Print cycle is programmable from 1 to 9.
