Hi I just wanted to know if any one out hear has had a problem with lifting in the palate area and if so what they did to stop this from happening any help would be greatly appreacted Thanks
Put up picture, is it happeninng on full palate only or also on horsehoe? How are you spruing? with a full palate do you have main sprue in postdam area & 2 secondary sprues at least near 6 & 11? What material are you using for duplicate model? type III or type IV, expansion or not? How long are you holding the material & how are you allowing for cool down? these are some of the things to consider.
