  Product Description

   

   

  Our precision vacuum UV exposure units are equipped with special UV lamps and auxiliary vacuum suction. After placing the screen and the printed clear film on the glass, close the lid, set the desired vacuum and exposure time and let it work, then make the screen and clear film stick tightly to the glass by vacuuming air The chamer that appears in the rubber blanket. After the set time is up, it will automatically deflate and the exposure will end. Please cut off the power.
  The exposure unit for iodine gallium light exposure has the same exposure effect. Although it has a slightly longer exposure time, due to its small size, light weight, low cost and easy transportation, it is very suitable for small businesses and home workshops to make high-precision screens.
  

  working principle

  The screen printing screen is coated with a photosensitive emulsion using a scoop coater. After the lotion dries, place the positive of the image on the screen. Once you burn the screen off, the emulsion that doesn't get any UV light washes off the screen, revealing tiny pinholes. Surrounding areas exposed to UV light will be cured. Therefore, the ink will pass through the screen to your substrate.

  2. Turn on the "POWER" switch;

  3. Set the vacuum time

  1) Press "VACUUM", the left indicator light (yellow) is on;

  4. Set the exposure time:

  1) Press "EXPOSURE", the left indicator light (red) is on;
  2) Press "+" or "-" in the "Time Control" area to set the exposure time as required. (The exposure time varies depending on the coating of the photosensitive emulsion, please set 300 seconds for testing, and then reset the appropriate time according to the exposure effect.)
  

  5. After completing the above settings, you can start exposure, as follows:

  1) Put the screen plate coated with photosensitive emulsion and the printed light-transmitting sheet on the glass;
