How to achieve high-precision manufacturing of powder metallurgy parts

To achieve high-precision manufacturing of powder metallurgy parts, several aspects should be considered:

　　1. Powder Selection and Preparation: Select high-purity, uniformly sized powder raw materials and use appropriate powder preparation methods to ensure powder quality and consistency.

　　2. Die Design and Manufacturing: Carefully design the die, considering factors such as shrinkage rate and draft angle, to ensure the size accuracy of the parts. Use high-precision processing equipment and technology to manufacture the die.

　　3. Pressing Process Control: Control parameters such as pressure, temperature, and time during the pressing process to obtain uniform density and size accuracy. Use advanced pressing equipment and processes, such as isostatic pressing and hot isostatic pressing.

　　4. Sintering Process Optimization: Optimize sintering parameters such as temperature, time, and atmosphere to control part shrinkage and deformation and improve accuracy. Select appropriate sintering furnaces and control systems.

　　5. Post-processing Process: Use appropriate post-processing processes, such as shaping, grinding, and polishing, to further improve the accuracy and surface quality of the parts.

　　6. Quality Inspection and Control: Implement strict quality inspection and control measures, including inspection and measurement, to ensure that the parts meet the accuracy requirements. Establish a quality management system and continuously improve the production process.

　　7. Technological Innovation and Cooperation: Continuously carry out technological innovation, explore new powder metallurgy technologies and processes, and cooperate with experts and institutions in related fields to jointly promote the development of high-precision manufacturing.
