Hi all, unfortunately at the moment I don't have the pictures with me but I was too curios to start investigating that I decided to give it a go without: Recently I have designed a chocolate mould for bars of the following size (mm): 150 x 75 x 6. Though the bar produced is actually thinner (4-5mm) this should be a relatively standard measure. What bugs me is that once the chocolate starts to set, the bar bends across the biggest length (150) making it not presentable due to the stains on the surface created by the bending as the chocolate gradually "leaves" the mould. Cooling temperature between 16/18degC. Any advices on how to address the problem? And while we are here merry christmas to all Marco

any news on the topic? From my side I can finally add a picture of how the chocolate bends Also, I realize I didn't give any detail about the mould. It is vacuum formed from thin plastic sheet like the one shown below It appears that this type of moulds can leave release marks (see chocolatetalk.proboards.com/thread/1402/35-release-marks-molds), I accept that. What it is not clear to me yet is whether the bending shown above is due to using this type of mould or not. Could it simply be related to the thickness of the bar and the temperature distribution in/and around it? If I move to polycarbonate mould, will the bending appear again? Any help would be much appreciated, Marco

Hi Marco,
this is answered in a few other spots on this forum. It is a function of the moulds you are using. The chocolate will not bend if you use a polycarbonate mould as they are thicker and more rigid. There's not a lot you can do with the thin moulds you have to stop the mould bending as the chocolate sets.

Hi gap, sorry for the loooong time left before replying. With regards to your observation on the few spots where I can find an answer, I have spent a considerable amount of hours searching for them and the result was the link that I included in my message above. By all means, if you are aware of any other link that better addresses my question please share it, I'll be very happy to have a look. Moving to a polycarbonate solution is expensive and before I do so I'd like to make sure that all my doubt are cleared. I have borrowed some polycarb. moulds and I'm going to try them this weekend. Let's see how it goes... Better safe that sorry Best regards, Marco
