Description
многозаходной- винтовой основной нарезкой 5 по наружной поверхности и с дополнительной винтовой нарезкой 6 по наружной поверхности5 противоположной по направлению основной нарезке 5, Мундштук 2 крепитс к корпусу I фланцем 7. В дорне 4 выполнен подвод щий канал 8, переход щий в радиальные каналы 9.
Дл подачи воздуха внутрь издели предусмотрен канал 10. К корпу су 1 Крепитс переходник 11,
В процессе работы расплав полимера нагнетаетс по каналу 8 экструдером /на чертежах не показан/ в радиальные каналы 9. Далее пО винтовым каналам 5 6 многократно сталкива сь и перемешива сь , расплав приобретает необходимую однородность распределени температурных и силовых характеристик. Подготовленный расплав, плавно выход из винтовых каналов 5,6 дорна 4 в зазор между дорном 4 и внутренней стенкой .корпуса 1, приобретает кольцевую форму , К формующему каналу 3 подходит гомогенный расплав, обеспечивающий получение качественного издели .
Экструзионна головка позвол ет получать высококачественные издели из различных полимерных материалов.
