High-precision parts manufacturing: There are many key components in power tools, such as gears and shafts, which have extremely high requirements for dimensional accuracy and positional tolerance. Powder metallurgy technology can directly produce high-precision parts, meeting the strict requirements of power tools for part accuracy, ensuring the fit accuracy between parts, and thereby enhancing the overall performance and stability of power tools. For instance, gears made by powder metallurgy have high tooth profile accuracy, smoother transmission and relatively lower noise.
Forming of complex-shaped parts: Some parts in power tools have complex shapes, making it difficult or costly to form them using traditional processing methods. Powder metallurgy can directly press metal powder into the required complex shapes through mold design, such as parts with irregular holes, grooves or special contours. This not only reduces subsequent processing procedures, but also lowers material waste and enhances production efficiency.
Material performance optimization: According to the performance requirements of different components of power tools, powder metallurgy can precisely adjust the material composition. For instance, for parts that require high hardness and wear resistance, alloying elements such as tungsten and molybdenum can be added to the powder. Through heat treatment processes after sintering, the parts can obtain good wear resistance and strength, extend their service life, and thereby enhance the reliability and durability of power tools.
