Conveyor - Uneven temps across the width of the oven HELP
I bought a fairly inexpensive conveyor oven last year, and I've always had trouble with uneven curing across the width of the tunnel. Typically the leftmost side of the belt is 50 degrees cooler than the right-center. I've compensated by running shirts down the right-center, sideways, in order to use as little of the width as possible. However, on shirts that have a design that is both tall and wide...I'm forced to use the entire width of the tunnel, and have been forced to deal with either scorching the right-center of the shirt, or undercuring the left.
I don't quite understand what's causing this, as the heat elements seem to be level and evenly dispensing heat? Are there any other variables I may be missing?? Would having the oven about 8 inches parallel to a wall (on the hot side) have anything to do with it?? I wouldn't think so as it is fairly well insulated.
Any ideas/advice would be helpful. Thanks in advance!

50 degrees diffference?!? wow, sounds like there is a big issue with your dryer. I would contact the manufacturer or place you purchased it. My guess is half your element is not working at all.

Yeah...its pretty bad when I can honestly say that there's not a 12" section along the width of the tunnel that will cure evenly enough to achieve satisfactory results...and it's a 20" belt. The "sweet spot" is about 8", where the temperature only varies by 15-20 degrees or so. Outside of that 8", the temp drops off drastically.
I contacted the company via email...as that's often the easiest way to describe a situation to its fullest. So, we'll see how they respond. I'll give them a chance to redeem themselves before I do my best to drag their name through the mud!! With a 5-year limited warranty...this one should be a no-brainer for them...replace the element!!!

It sounds like your heat panels are junk. If it's new. it's a manufacturing problem. If it wasn't such a drastic difference, it could be air intake/ exhaust settings. Or maybe you do not have the correct amount of power. If it is a 220v it could be wired wrong. If it has a built in thermometer, it could be bad, Causing wacky fluxuation in temp. Did you wire it yourself? because if you did, you might not want to tell the manufacturer that, sometimes it voids warranty. good luck!
