Abstract

Шнекът (27) се използва при инжекционно формоващамашина или екструдер и включва шнекова ос (39) с витки (41), спирално установени около нея така, чеда се оформят множество лопатки (43, 45, 47). Шнекът (27) има три участъка (29, 31, 33) - захранващ(29), уплътняващ (31) и дозиращ (33), а височината и стъпката на лопатките (43, 45, 47) са конструирани на основата на материала, който ще бъде използван в шнека (27) така, че разликата в съотношението на действителния към теоретичния съпротивителенпоток от материал в захранващия участък (29) и съотношението на действителния към теоретичния съпротивителен поток от материал в дозиращия участък (33) е по-малка от 0,2, по-специално по-малка от 0,1 и по-точно - по-малка от 0,05. Шнекът (27) има поток с балансирана маса и, следователно, постояннонарастващо налягане по дължината си, без максимално налягане.
