Thanks all. I tested my know-how again using good, solid molds from Tomric (my own family's company had just one tray of three different shapes). Anyway, every single mold fell out beautifully.
@Mark-allan, maybe Fat Daddio was not what we got then. I know that is a name I've seen around. In any case, I do believe now that what i have been provided is crappy tools, and they are just going to have to spend the extra money if they want good molds and fewer losses of product.
Thanks again!
