Izici zenqubo:ukwakheka komugqa, izibhamu eziyisithupha. Inqubo yokukhiqiza ye-self-hardening sand ku-in-line yamukelwa ukuhlanganiswa kwe-core ku-in-line, ukubekwa kwe-core nokusakaza. Izinto ezibunjiwe zisakazwa ngenqubo yokusakaza evundlile, futhi amanzi afakwa ku-multi-layer ingate, okuthuthukisa ngempumelelo ukufana kwendawo yokushisa yensimbi encibilikile ebusweni bebhokisi lesembozo. Kwinqubo yokukhiqiza, izinga leziphazamiso zezimbobo namachibi esihlabathini ezintweni ezibunjiwe liphansi, futhi ikhwalithi izinzile futhi ingalawuleka.
