Abstract

A sand shell-moulding method for the production of a part for use in the automotive and aeronautics fields, in which: a metal or alloy is poured into the shell mould in order to produce a part; the shell is forcibly and rapidly cooled; and an operation of decoring of the part is realized.

Claims

exact text as granted — not AI-modified

1 / A sand shell-moulding method, for the production of a part for use in the automotive and aeronautics fields, in which:
 a metal or alloy is poured into the shell in order to produce a part,   the shell is forcibly and rapidly cooled,   an operation of decoring of the part is realized.   
     
     
         2 / A sand shell-moulding method, for the production of a part for use in the automotive and aeronautics fields, in which:
 a metal or alloy is poured into the shell in order to produce a preform,   the shell is forcibly and rapidly cooled,   an operation of decoring of the preform is realized,   the preform is subjected to a combined pressing and forging operation.
