Vacuum Exposure Unit 110V

ASC6050ZK Precise Vacuum UV Exposure Unit is equipped with special UV lamps and auxiliary vacuum suction device. After putting the screens and well printed transparency film on the glass, close its cover and let it work after set the needed vacuum and exposure time, then it will make the screens and transparency film close on the glass tightly by evacuating the air of the vacuum charmer emerging from the rubber blanket. When the set time is up, it will deflate automatically, and then the exposure is finished. Please cut off the power supply.

Working principle

Screen printing screens are coated with a light sensitive emulsion using a scoop coater. When the emulsion is dry, place your image with a positive print on the screen. Once you burn the screen, the emulsion that did not get any UV will wash out of the screen exposing the tiny pin holes. The surrounding areas that were exposed to UV will be cured. Hence the ink will pass through screen onto your substrate.

The vacuum pumping area (sizes of the rubber blanket) is 23.6”*27.6” (60*70cm), but the optimum screen exposing size is within 19.7”*23.6”*1.6” (50*60*4cm) by the outer sizes. (If your screen is oversized, please buy cautiously!)

1. Connect the power supply; Turn on the switch of “POWER”;

2. Set the vacuum pumping time

1) Press “VACUUM”, the left indicator light (yellow) is lit up;

  2) Press “ + ” or “ – ” in the “TIME CONTROL” area to set the vacuum pumping time according to your needs.

3. Set the exposure time

  1) Press “EXPOSURE”, the left indicator light (red) is lit up;
   2) Press “ + ” or “ – ” in the “TIME CONTROL” area to set the exposure time according to your needs.

4. Once finished the above settings, you could start exposure just as follows

5. Functions of other keys

1. If the digit was not displayed once turned on the switch

a. Please check whether the power supply is good or not

b. Please check whether the bottom fuse wire is loose, burned-out or not

2. If the vacuum pump didn’t work after putting the screen on the glass, closing the cover and pressing the “STRAT” button:

Please check whether the leading wire of the vacuum pump is well connected or not

3. If it didn’t reach the requirement even the vacuum pump works well

a. please checks whether the air suction pipe is well fastened or not

b. Please check whether the rubber blanket and its edgings were good and seal or not.

If there were some splits on the rubber blankets or edgings, or some cracks of the edging adhesives, please fix them up with the sealing adhesive.

4. If the lamps were not lit up

a. Please check whether your voltage was too low or not

b. Please check whether the lamp ends were blackened or not caused by lamp ageing

c. Please check whether your set exposure time was 0 second

d．Please check whether the ballast was broken or not.

1) Please cut off the power supply when you need to change the lamp or the ballast

2) Avoid contact with hard objects to prevent glass surface scratching

3) Consistent cleaning is needed according to your using frequency and operational environment, especially for the glass, vacuum rubber blanket and edgings
