With the rapid evolution of intelligent manufacturing, industrial robots are quickly upgrading toward lightweight design, high cycle speed, low energy consumption, and high stability. Traditional industrial robots mostly use aluminum alloy housing structures. Although they can meet basic operating requirements, they still face industry pain points such as relatively high self-weight, limited dynamic response, high energy consumption, and insufficient vibration damping and electromagnetic shielding performance. These limitations make it difficult for them to adapt to modern flexible production scenarios requiring high precision, high frequency, and long-duration operation.
To break through the application limitations of aluminum alloy materials and reshape the structural design standards of industrial robot bodies, our company joined hands with STAUBLI, a global leader in industrial automation, to carry out in-depth joint technological R&D. Relying on the core strengths of both parties in robot system development, new material die-casting processes, and structural optimization design, the teams focused on lightweight robot body housings and performance upgrading. Together, they tackled the development and implementation of an all-magnesium housing industrial robot project, ultimately achieving breakthroughs in both technology and mass production.
The core highlight of this joint development project is the integrated all-magnesium housing body design. The complete machine abandons the traditional aluminum alloy assembled housing structure and instead adopts 13 high-precision AZ91D magnesium alloy high-pressure die-cast components. These components fully cover the robot’s core body structures, including the base, rotary housing, upper arm, wrist, and motor housing, realizing an integrated, lightweight, and high-strength robot body housing design.
As a high-end lightweight structural material, AZ91D magnesium alloy offers unique advantages such as low density, high specific strength, excellent vibration damping performance, good electromagnetic shielding capability, and high die-casting forming precision. It is highly suitable for the operating requirements of industrial robots involving high-frequency operation, dynamic movement, and precision production.
At the same time, the R&D teams of both parties carried out dedicated optimization of the magnesium alloy die-casting process, structural mechanical distribution, and complete machine compatibility. They solved key technical challenges such as forming precision control for magnesium alloy, structural strength adaptation, and long-term operational stability, ensuring the practicality and durability of the all-magnesium housing structure.
After multiple rounds of testing, debugging, operating condition simulation, and on-site application verification, this all-magnesium housing industrial robot achieved comprehensive upgrades in lightweight performance, operating efficiency, energy consumption control, and operational stability compared with traditional aluminum alloy solutions of the same specification. The core performance indicators achieved precise breakthroughs.
Relying on the advantages of magnesium alloy materials and integrated structural optimization, the robot housing parts achieved a weight reduction of 34.6% compared with aluminum alloy solutions of the same specification. The total weight of the complete machine was reduced by 11%.
The significant reduction in body weight effectively lowers the robot’s motion inertia and reduces the load on the transmission system, laying a solid foundation for high-speed precision operation and flexible movement. It also reduces the difficulty of equipment installation and maintenance.
The lightweight body structure effectively shortens the robot’s motion response time and improves dynamic operating flexibility. Test data shows that the overall operating cycle efficiency of the equipment increased by 5%.
In high-frequency repetitive operation scenarios such as assembly line handling, sorting, and assembly, the effective daily working time and production capacity are significantly improved, enabling the robot to efficiently meet the needs of high-efficiency automated production lines.
The reduction in body load greatly reduces the power consumption of the drive system, lowering overall equipment energy consumption by 10%.
In long-term large-scale applications, this helps enterprises effectively reduce production energy costs and carbon emissions. It is in line with the development trend of green, low-carbon, energy-saving, and efficiency-enhancing manufacturing, providing core support for cost reduction and efficiency improvement in intelligent manufacturing.
Compared with traditional aluminum alloy housing solutions, AZ91D magnesium alloy offers better vibration damping, noise reduction, and electromagnetic shielding performance.
During high-speed reciprocating operations, the equipment experiences lower vibration amplitude and reduced operating noise, effectively improving the precision stability of high-accuracy operations. At the same time, its excellent electromagnetic shielding capability helps resist complex electromagnetic interference in industrial environments, ensuring long-term continuous and stable operation, reducing the probability of failure-related downtime, and making the robot suitable for demanding operating scenarios such as precision electronics and high-end manufacturing.
At present, the all-magnesium housing industrial robot jointly developed by both parties has completed technical finalization, multiple rounds of operating condition testing, and production line adaptation verification. It has successfully achieved batch supply and officially entered market application.
The mass production of this product has broken the long-standing industry pattern in which industrial robot housings mainly rely on aluminum alloy materials. It has also verified the feasibility of large-scale application of magnesium alloy materials in high-end industrial robots.
From an industry perspective, this joint innovation not only establishes a new robot development model integrating “new materials, new structures, and high performance,” but also effectively solves the long-standing pain points of traditional industrial robots, where self-weight, efficiency, energy consumption, and stability are difficult to balance.
It also provides a benchmark reference case for the lightweight upgrading of intelligent manufacturing equipment and the industrial application of new materials. In the future, both parties will continue to deepen technological cooperation. Relying on the advantages of magnesium alloy materials and structural design experience, they will continue to optimize product performance and expand application scenarios, helping the high-end industrial robot industry evolve toward greater efficiency, lower energy consumption, and higher precision.
