Looking for info from anyone who has re fitted a textile dryer to a UV dryer without buying a kit from mfg.
Does'nt make sense what your asking.
Are you wanting to convert a UV curing unit to a textile dryer or are you trying to convert a textile dryer to a UV curing unit?
Without an engineering degree, I would'nt know where to start.
Our industry accomodates quite a range of equipment across the technological range from cave man to space man.
It's not uncommon for really neat "cave man" apparatus' that worked as well and as fast as far more technologically advance systems. (there was a guy using the sun to shoot his small t-shirt screens with a wooden built contraption that was highly accurate........you had to see it)
THIS HOWEVER, is NOT something you want to mess with. I don't even know how you would build a housing if you did get your hands on some bulbs.
No, your best best is to buy a used "attachable" UV unit on the web somewhere and mount it to your exhisting belt apparatus.
Build your own:
vacumn print table
"one arm" squeeguee print table
all kinds of things, BUT NOT A UV CURING UNIT...........
Rocky is 100% correct. I know of a press manufacturer in Ohio played with UV lighting on a "newly designed press". Made their own housing, sheilds etc. We went there about six months later. You could turn the lights off and read a newspaper with just the UV lights on from the press.
We saw three guys with burns on their arms and faces from the lights. The metal on the press was glowing red after 15 minutes which could have caused a major fire. We also had three fires in the unit burning up substrates during the 2 hours we were there.
UV curing and lights are nothing to screw with if you don't know what you're doing.
I did that myself 30 years ago and used the Sun to expose screens, works well. Exposing UV inks with the Sun is an entirely different matter. Wish it were that easy, everone would be doing it, and it would have been done long ago. We would't have 1.5 million dollar in-line presses UV if I could use the Sun to do the job.
I understand that this not rocket science but pushing the envelope a bit to use the Sun on UV inks. I have done it, it semi worked, on one color, real thin deposits, and depending on the color, pigment load etc. and the deposit it might work, but I would be real hesitant on who I gave the prints to, where, and what they were going to do with them.
If you ever have put a sheet with UV undercured inks in a closed environment for any length of time and then opened them up the smell of the uncured monomers is a bit much.
Quit your howlin' Wolff.
Solar exposing works great. Except during the cold dark winters up here. Accurate if done with a light integrator and vacuum frame, and extremely fast - 6" screen or 16' screen in the same amount of time - I average a minute on yellow 305 with Murikami 9800 dual cure in summer.
UV inks cured by the sun? That is interesting. Maybe not practical on night shift, but if the band width of the light was matched to the ink and your shop was located in Mexico.....
Check out www.tmiscreenprinting.com in a few weeks, (test site only right now) we will have some inexpensive UV dryers up with the other new equipment.
