Cold forging forming method for three-dimensional hollow article
Accordingly, using liquid mercury as a freezing medium can increase cost of production, and can induce quite much trouble in management of operation, and this is the motive of study and development of the present invention. The inventor of the present invention invented the cold extrusion forging forming method for forming a three-dimensional hollow article without rough edges based on his specific experience of years in metal processing.
The main object of the present invention is to provide a cold extrusion forging method for forming a three-dimensional hollow article without rough edges, wherein, an alloy of low melting point is used as a plastic filler with plasticity, thereby an object of changing or recovery for reusing the filler can be achieved, and cost of forming can be reduced.
