Abstract

Inventia se refera la un procedeu de fabricare a pieselor turnate din cel putin doua piese componente, care, într-o prima faza de lucru sunt turnate si întarite, folosind în special turnarea sub presiune si vulcanizarea, iar în a doua faza de lucru piesele componente se asambleaza si sunt vulcanizate împreuna. Inventia se refera de asemenea, si la un dispozitiv de fabricare a pieselor turnate compuse din cel putin doua piese. Inventia îsi propune ca piesa turnata sa poata fi realizata si din mai multe parti folosind materiale diferite, pisele fiind si mai durabile si mai rezistente decît cele obtinute pîna în prezent. De asemenea, cu ajutorul procedeului si instalatiei în conformitate cu inventia se realizeaza o productivitate mai mare.
