We have two dryers in house over here, a Sprint International, and a new to us mini sprint.
Typically we run our sprint international between 305 and 335 depending on the application.
When the tech from GSG was here installing our mini sprint he said he'd never seen a shop run a dryer that low before, and had set up the mini sprint for 400 degrees!
So what is the typical temp you keep your dryer at? i know it'll vary from shop to shop, and dryer to dryer, but 400 seems so high!
-
400 is typical. All our dryers run @ 400
-
how fast are the belts going?!
-
Depends on the ink. We have settings but I don't give them out as I never trust the digital readouts. Its about retention time anyway. Depends on how long the dryer is. One is an Interchange
-
Mu old dryer sets by panel temp, so my 1100 is really high, number-wise.
Where are they reading the 400 on these dryers? Or is just a relative reading for an average garment and ink layer? (similar to a non-contact gun)
-
I have an Interchange AirJet and we run just about everything at 350-355 with belt
speed 15-17 feet per minute. Of course lower temps for poly and puff. I have to
slow the belt speed for puff also.
-
400 here too. Speed depends on.......

I have a mini sprint with an 8 ft chamber. I run mine at 400 to 410 with a belt speed of 15 or 16. If there is no white printed, I will speed it up to 17 or 18 at the same temp
-
This is blowing my mind.
What type of probe unit should we get? Tony any recs?
-
Our old precision I keep around 400-410, bump panels 500-600. 45 seconds to a min for plastisol, 1:30-1:45 water base, 10' chamber. 380 and 45 seconds for poly a little quicker for nylon.

Donut
where can we get one?

We run our Heatwave between 325-340 depending on ink type at 60 secs through the tunnel, and slow the belt down a bit for WB and discharge prints. I've heard of running the belt quicker at a higher temp but didn't realize so many people were doing it. Is this standard in the industry, or are there negative effects that can come along with it? I'd be very happy to hear I could increase my dryer capacity with a few minor adjustments.
It may be time to get a donut.
-
400, use a donut.

Donut
Global Industrial carries Atkins $148.00
where can we get one?
-
Some non contact guns have a jack for a cable for a probe, so can do double duty.
-
We have a 12 foot Sprint 2000 HO.
Plastisol: We run at 327 for 50/50 blends at 12 speed (1 minute in the dryer) 100% cotton at 340 and 12-16 Depending on flashing/manufacturer/color of garment/thickness of ink.
WB/Discharge: 340 and 6-8 speed (1:45-2:00 in the dryer)
If we are running Wilflex Top Score: 295 and 16 speed or faster depending on how thin the poly is.
-
Sprint International, 12' heat, 60" belt, 360 degrees and 22'/minute for light garments with thin layers of ink and 370 and 20'/min for darks with underbases.

I was very impressed with our dryers settings compared to what it actually is inside. I know a lot of dryers aren't that way. If you set ours to 360, it will be 360 degrees throughout the entire chamber according to the donut probe. It's nice to know that you can count on the settings to be true, the belt speed is dead on as well. With our belt set to 24, the garment is in the heat chamber for exactly 30 seconds, 24' per minute right on the dot. Most ink deposits hit 320 with about 2' to go with our settings and if we're using a thicker layer of ink than normal I may turn the belt speed down by 2-3 units and bump the temp up 10 degrees. When the tech was here he told us what most shops run the sprint at so that's where I started and using the probe a few times (an hour a day for the first few weeks) I dialed in the settings and I think we could go down more on temp and lower belt speed but I need the belt to run without slowing the auto down.
-
360, speed 16-18, 12ft heat Sprint.
-
400 here too in our VINTAGE Vortex.....cooks my bagel perfect....little italian dressing on it, boom -heaven.
-
Black 100% cotton tees we run at 338 degrees, retention time 1 minute, oven length 3 meters. Dry fit tees we run at 320 if printed with standard poly inks, when we use Wilflex Performance we go down to 311 degrees and run them as well a little faster.
Discharge we do at 374 for 2 minutes.

need a donut..
