In modern manufacturing, the importance of powder materials is becoming increasingly prominent. Especially in the field of robot manufacturing, powder materials account for more than 65% of the weight of the robot, such as metal powder, ceramic powder and composite powder. With the continuous advancement of technology, the precision of powder processing has also achieved a leap from millimeters to nanometers. It provides a solid foundation for high-end manufacturing.
The Revolution of Powder Precision: from Millimeters to Nanometers
In the past, the particle size control of powders was mainly at the millimeter or micron level. It was difficult to meet the manufacturing requirements of high-precision, lightweight, and high-strength robot components. Today, relying on advanced grinding, classifying, and granulation technologies, the particle size control of powders can be accurate to the nanometer level. This extreme control of particle size not only improves the uniformity of powder distribution, but also greatly improves the density of the material and the mechanical properties of the final product.
Airflow Classification Technology: Achieving Ultra-fine Particle Size Control
As one of the most cutting-edge classification methods, air classification effectively screens powders of different particle sizes through high-speed airflow, and the particle size control accuracy can reach 0.1μm. This technology is particularly suitable for the manufacture of robot parts with extremely high requirements for particle size distribution. For example, powder materials used for 3D printing metal parts or composite functional powder materials used in flexible robots. The consistency of particle size is directly related to the molding accuracy and service life of the final parts.
Plasma Spheroidization Technology: Improve Fluidity and Density:
Traditional irregular-shaped powders often have problems such as uneven stacking and high porosity during processing. The application of plasma spheroidization technology can melt the surface of the powder at high temperature. Under the action of surface tension, it automatically shrinks into a sphere with a sphericity of more than 95%. Spherical powders have better fluidity, filling and density. They are particularly suitable for metal additive manufacturing, powder metallurgy and the preparation of high-performance coating materials. They are key factors in improving the integrated molding and strength control of robot parts.
Powder Surface Modification: Giving Multifunctional Properties
In addition to the improvement of particle size and morphology, the surface modification technology of powders is also promoting the multi-dimensional leap of robot material performance. Specific functional groups or composite coatings are introduced on the surface of powders by physical or chemical methods. It can not only enhance the bonding force between powders and matrix materials, but also give materials special properties such as conductivity, insulation, corrosion resistance, and self-lubrication. For example, in bionic flexible robots, the use of modified conductive carbon nanopowders can significantly improve the response sensitivity and stability of sensor components.
Promoting the Future Development of Robot Manufacturing
Powder processing technology has evolved. It is no longer just about “material filling.” Now, it plays a key role in pushing the performance limits of robots. New breakthroughs continue to emerge. These include high purity, ultrafine particle size, high sphericity, and functional modification. Such advances enable better structural materials, drive components, sensor systems, and energy units for robots. Looking ahead, AI and automated manufacturing will further integrate with powder technology. This will enhance robot intelligence, reduce weight, and support complex structural designs.
