To achieve high-precision manufacturing of powder metallurgy parts, the following aspects can be considered:

　　1. Powder selection and preparation: Choose high-purity, uniformly sized powder raw materials, and use appropriate powder preparation methods to ensure the quality and consistency of the powder.

　　2. Mold design and manufacturing: Carefully design the mold, taking into account factors such as shrinkage rate and draft angle, to ensure the dimensional accuracy of the parts. Use high-precision processing equipment and technology to manufacture the mold.

　　3. Pressing process control: Control parameters such as pressure, temperature, and time during the pressing process to achieve uniform density and dimensional 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 the shrinkage and deformation of parts, improving accuracy. Choose appropriate sintering furnaces and control systems.

　　5. Post-processing: Use appropriate post-processing techniques, 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 testing and measurement, to ensure that parts meet accuracy requirements. Establish a quality management system to continuously improve the production process.

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