#CMT# #/CMT# The process for molding a metallic part e.g. aluminum alloy comprises casting a liquid metal (12) in fusion within a mold (14), and cooling the metal for causing a solidification of the metal and reducing a temperature of the solidified metal by transferring heat between the metal and a wall (30) of the mold. The step of cooling comprises retracting the wall of the mold, and projecting cooling liquid directly on the metal through an orifice exposed by the wall. The step of retracting consists of causing dissolution of wall of the mold by projection of a liquid dissolving on wall of mold. #CMT# : #/CMT# The process for molding a metallic part e.g. aluminum alloy comprises casting a liquid metal (12) in fusion within a mold (14), and cooling the metal for causing a solidification of the metal and reducing a temperature of the solidified metal by transferring heat between the metal and a wall (30) of the mold. The step of cooling comprises retracting the wall of the mold, and projecting cooling liquid directly on the metal through an orifice exposed by the wall. The step of retracting consists of causing dissolution of wall of the mold by projection of a liquid dissolving on wall of the mold, where the retraction is carried out after the solidification of the metal part, which is in contact with wall of the mold to retract. An independent claim is included for a system for molding a metallic part. #CMT#USE : #/CMT# The process is useful for molding a metallic part (claimed) e.g. aluminum alloy. #CMT#ADVANTAGE : #/CMT# The process improves the mechanical properties of the molded metallic part using the cooling unit. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The diagram shows a molding system. 12 : Metal 14 : Mold 18 : Metallic shell 28 : Jet 30 : Wall. |
