This year the of the IMA Award of Excellence for Commercial Cast Product Design goes to the magnesium housing of the ER4-550-MI Industrial Robo. It is presented to: Estun Automation Co., Ltd; Nanjing Yunhai Light Metals Precision Manufacturing Co., Ltd; Baosteel Metal Co., Ltd. and BAOWU Magnesium Technology Co., Ltd.
Name of Part: Mg Alloy Housing for an Industrial Robot
 Product Using Part: ESTUN ER4-550-MI Industrial Robot.
 Function of Part: Whole of industrial robot.
 Alloy Used: Magnesium Alloy, AZ91D
The magnesium housing of the ER4-550-MI Industrial Robot is the world's first fully magnesium housing for an industrial robot, setting a new standard in Mg application. Comprising 13 magnesium high pressure die-cast (HPDC) components, this housing offers a 34.6% reduction in weight compared to its aluminum counterpart, leading to a 11% overall weight reduction in the robot. Additionally, it enhances performance in terms of speed (+5%), energy efficiency (-10%), stability, shock absorption and electromagnetic shielding.
