st3042 and Ricoh printer
doing some iPhone cases and the last batch I had seemed to cool ok on dummy phones, but not in cold water as I found they warped.
Got a new batch of Galaxy S4 and iPad mini cases from another supplier as my normal supplier was out of stock. Slightly different design to the S4 case, which is no problem. But I can not get them to cool without a lot of warping on a corner and shrinking using a dummy phone.
using dummy phones was the advice given to me by a supplier on here when I first started, but what are the opinions of guys on here? Like I say, this new batch just pop off as they change shape as they cool, even if I put some weight on them.
