Man I have several molds from here and they all shoot super clean. I am just now purchasing laminate plates for the egg molds I have, ive done a swirl effect on them as well using a double injector and rotating it in a circle as I shoot. Plastic has to be hot and mold hot as well, I would say at least 90° on mold and nothing less than 320° for plastic. Be prepared for it to suck up the plastic, you will need at least 6oz injectors for this big guy, but its totally worth it. Just now trying around with small solid red eggs inside the mold before I shoot to create a blood dot transparent orange natural egg. There's so much you can do with these molds its almost unlimited.
