Abstract

Αντικείμενα από πλαστικό σε καλούπι τυπώνονται με την εναπόθεση ενός φύλλου, ή ενός στρώματος πλαστικοποιημένου υλικού με αναρρόφηση επάνω στο εξωτερικό τμήμα που σχηματίζει το περιτύπωμα ενός καλουπιού που είναι διαπερατό για να επιτρέψει σε ένα εργαζόμενο αέριο μέσο να επιδράσει επί του υλικού διαμέσου του υλικού του καλουπιού. Πριν από την επίδραση αυτή, κατασκευάζεται ένα καλούπι που τουλάχιστον για το τμήμα του καλουπιού που σχηματίζει το περιτύπωμα του καλουπιού αποτελείται από ένα ειδικό σύνθετο υλικό του οποίου τα σωματίδια συνδέονται μαζί για την δημιουργία μιας εξωτερικής κατασκευής σταθερής φόρμας που να έχει περάσματα αέρα που να εκτείνονται ως το εξωτερικό του καλουπιού. Η αναρρόφηση γίνεται μετά επάνω στο έτσι δημιουργημένο καλούπι. ωMolded plastic objects are printed by vacuum depositing a sheet, or layer, of plasticized material onto the outer portion forming a mold cavity that is permeable to allow a working gaseous medium to act on the material through the mold material. . Prior to this effect, a mold is made which, at least for the part of the mold forming the mold profile, consists of a special composite material whose particles are bonded together to create an outer structure of fixed form having air passages extending as the outside of the mold. The suction is then applied to the mold thus created. oh
