Abstract

Lorsque des produits moulés semi-finis (2, 3) sont destinés à être réunis par une deuxième injection pour former un produit fini (1), on prévoit que les produits semi-finis (2, 3) puissent être simplement démontés et récupérés sous forme de parties individuelles. Les produits semi-finis (2, 3) sont formés avec un espace de vis de retenue et aboutés les uns aux autres pour effectuer la deuxième injection. Alors qu'ils se trouvent dans cet état, on injecte, dans l'espace de vis de retenue, une matière d'injection qui adhère fortement ou bien qui n'adhère pas sur les produits semi-finis (2, 3), pour former une vis de retenue (4) ; les produits semi-finis (2, 3) pouvant ainsi être réunis alors qu'ils se trouvent à l'état démonté.
