Motorcycle Frames Temp & Time

[Guest]

Hello everyone. I've been browsing for a while usually there's a answer for my questions in the forum. So thanks for all the past help. I have a question about coating frames. I will be using mirror black. How long does it normally take to bring a frame up to temp. If it take a hour to bring a frame to 400 degrees is that acceptable? Then once the frame is at temp I leave it for the required cure time. Thanks for any info.

Thanks, I wasn't sure if I could the coated frame in the oven for the 50 or 60 minutes it takes for the frame to reach 400, without overcooking the powder.

Thanks again for all the info. DDD

If you have an oven or part that heats up slowly then it may not need to be in there for that long. Most powders have different cure schedules at lower temps. I have done some thicker cast parts that could take 30 min to get from 350-375 degrees and the powder is fully cured at that point because the cure parameters for that powder were 10 min at 392 or 25 at 350. I hope thats not confusing but all powders have a range they can cure at you just need to learn your oven and the powder you are using.

Thanks, to you, Jason & HarleyDad

I shot the frame tonight. Preheated the oven to 425. Everything but the cast neck and rear motor mount area which is also cast got to 400 in about twenty minutes. I let the frame cook at 400 for another twenty minutes. At that point the cast sections were about 380. Hopefully everything is cured. I was worried the thin sections might suffer from being at 400 for too long a period of time. Frame looks good, smooth and good shine everywhere.

As always I appreciate the time you all take with those of without much experience.
