Abstract
Методът намира приложение в леярското производство за изработване на отливки от алуминиеви сплави. Получените отливки са без газови шупли и въглеродни включвания по повърхността си и са с подобрена плътност. По метода се прилага нарастващо изостатично налягане върху формата след изгарянето на стопяемия модел, при което скоростта на нарастване е такава, че поражда подналягане в междуфазовата повърхност между металната стопилка и формовъчната смес. Подналягането достига стойност, определена от две гранични стойности, и след това намалява, а прилаганото налягане се увеличава до максимална стойност и се поддържа до пълната кристализация на изработваната отливка. 5 претенции
