Abstract

Настоящее изобретение относится к шнеку (27), предназначенному для использования, например, в машине для литья под давлением или в экструдере. Шнек (27) содержит вал (39) шнека с резьбой (41), расположенной по спирали спирально вокруг вала (39) шнека с образованием множества витков (43, 45, 47). Шнек (27) имеет три зоны (29, 31, 33), зону (29) подачи, зону (31) сжатия и зону (33) гомогенизации, и при проектировании высота и шаг витков (43, 45, 47) шнека (27) определяются на основе материала, используемого в шнеке (27), таким образом, что разность между отношением фактического расхода к теоретическому расходу увлекаемого материала в зоне (29) подачи и отношением фактического расхода к теоретическому расходу увлекаемого материала в зоне (33) гомогенизации составляет менее 0,2, предпочтительно менее 0,1 и более предпочтительно менее 0,05. Эта конструкция обеспечивает образование шнека, который имеет сбалансированный массовый расход, и таким образом обеспечивается постоянное приращение давления вдоль шнека без пиковых значений давления.Международная заявка была опубликована вместе с отчетом о международном поиске.
