The choice of magnesium alloys for robots is primarily based on their advantages such as lightweight high strength, excellent heat dissipation, and superior shock and vibration resistance.
– Lightweight High Strength: The density of magnesium alloys is about 2/3 that of aluminum and 1/4 that of steel, significantly reducing the weight of robots and lowering the load on the drive system, allowing for faster joint rotation speeds and quicker response times. Moreover, their specific strength exceeds that of many engineering materials, making them suitable for use in robotic arms and skeletal structures, ensuring structural strength and durability while reducing weight.
– Excellent Heat Dissipation: Magnesium alloys have a thermal conductivity that is 350-400 times greater than that of ABS resin, allowing for rapid conduction of heat generated by joint actuators and internal electronic components, preventing overheating and ensuring stable operation of the robot, thus avoiding failures due to overheating.
– Superior Shock and Vibration Resistance: The internal damping coefficient of magnesium alloys is significantly higher than that of aluminum alloys and steel, effectively reducing resonance effects and improving the stability of robot operation, which is crucial for robots requiring precise operations, such as medical robots and bionic robots.
– Diverse Shapes: Magnesium alloys can undergo various surface treatments such as oxidation, painting, and electrophoresis, enhancing the aesthetic appeal of robots while meeting customization needs and improving durability.
– Mature Processing Technology: Semi-solid injection molding technology has become the core solution for processing magnesium alloys, offering advantages over traditional die casting, including higher safety, environmental friendliness, fewer gas defects, better mechanical properties, and lower energy consumption.
Xingyuan Zhuomei is primarily engaged in the precision die casting of magnesium and aluminum alloys. In 2024, the total production is expected to be 6.9637 million pieces, covering die-cast parts in both automotive and non-automotive fields. Based on working hours, the production capacity for 2024 is 961,600 hours (theoretical working hours).
