[UK Printed Mugs]

Simon, those bands work a treat!!! Saved me from so much hassle trying to peel off the shrink wrap. I did though do a trial with placing a cut silicone sheet taped on top of the artwork before the band is fitted and this really helped with gassing issues. Without the paper then the bands got all discoloured as well but by cutting A4 sheets into strips (short width of A4 is ideal length to wrap around the mug) then this prevented it. Could I ask two things: (1) What is the max number of enamel you have tried in the oven and do you alter the time if say over 8 (our max at the moment)? (2) After taking out do you wait for the temp to go back up as sometimes the temp drops to 150/160 whilst door is open? Cheers

Ps: Got silicone paper from here

Glad to hear it worked for you.

With regards to the other questions, I have never bulked printed enamel mugs, but here is where I would start...

I would use the same amount of items as if there were ceramic. I would do this (in the first instance) because I know that one mug versus 18 mugs is an increase in time of approximately 115-125%. So if 1 mug takes 8 minutes, 18 mugs will take 18 minutes. This is all approximate, but then you have a decent amount of leaway in an oven anyway. You may want to put 18 mugs in the oven and start removing them one by one every minute starting at minute 11. Remove 1 mug, peel off the paper and see what it is like. If its perfect you have the best time, if it needs a little bit longer you have more in there to check (I hope I have explained that correctly). Bear in mind that metal heats up a lot quicker than metal hence why I have suggested minute 11. One batch of 18 mugs should give you near on the perfect time and once you have that perfect time, put another batch of 18 in the oven, knock 30 seconds off the test time and give that a go.

I suggest knocking 30 seconds off the test time as you will have reduced the temp a wee bit when removing your test mugs.

I never wait for the oven to heat up when on a mug "run". Pull out the trays, bang two more trays in and hit the timer.

12 enamel mugs, 12 mins, 160 degrees with silcone wrap.

Hi Gary. That's an interesting time. I did initially do 160/20m which was fine but will drop to 12mins and see. Thanks.

A photo of the BestSub 70l oven with digital controller which seems to be very accurate. Although shrink wrap is working well for enamel it is not great to use plastic and throw away so I am going to try DIY wraps this week using cut silicone strips and bulldog clips. Will test and share results once done.

What do you think of this oven?

I got the free sub st3042 which is a POS and has failed after 3 weeks

So it’s a toss up between this and the blizzard

How did the diy wraps go?

Where did you get the silicone sheets?

Very informative thread.. thought I’d bump it to see if there have been any revelations since 2021 [emoji854]

I'm looking to upgrade to an oven! So any suggestions?

What a fantastic thread. Just thinking of starting printing again in the new year and using an oven this time.
:biggrin:

It is a shame you are not near Manchester, JMugs. I think we will have 2 ovens and about 200 wraps up for sale in the New Year.
