Aluminum alloy molding production process involves applying working gas pressure to blank, which is at 200-400 degrees C during deforming process

摘要

The molding production process involves sealing a blank in a parting tool with appropriate cavity for the end product, allowing for displacement. A controlled working pressure is applied by a gas to the inside of the blank, which is kept at a temperature of 200-400 deg C during the deforming process, which proceeds without complete recrystallisation of the material.
