Zhenglang Precision | How To Produce High-precision Powder Metallurgical Parts During Processing?
In the manufacturing industry, high-precision powder metallurgy parts are widely used in aerospace, electronics and other fields, with their unique advantages. However, it is very difficult to manufacture such parts and requires strict control in many ways. The following is the edited share.
1. Screening raw material powder
High purity and accurate particle size powders are the basis for the manufacture of high-precision powder metallurgy parts. The higher the purity, the more it ensures the stability of the part and reduces problems caused by impurities. At the same time, precise control of powder particle size and its distribution can ensure consistent shrinkage during compression and sintering and improve the accuracy of the parts.
2. Design and manufacture of mold
The mold structure is optimized using CAD and CAE techniques to ensure uniform powder filling and reduce density imbalance and dimensional deviation. Manufacture molds through high-precision processing equipment, select high-quality materials to ensure the accuracy and service life of mold, stabilize molding accuracy, and assist in the production of high-precision powder metallurgy parts.
3. Processing technology
Isostatic pressure technology enables the powder to withstand uniform stress, thereby improving the density uniformity and dimensional accuracy of the parts. Vacuum or atmospheric protection sintering technology can reduce oxidation and impurity contamination, accurately control temperature and time, and evenly shrink parts.
4. After the parts are sintered
Size deviations are compensated by precise processing such as grinding and grinding. Use three-level measuring instruments and other equipment to conduct comprehensive inspections, establish a quality control system, and ensure that every high-precision powder metallurgy component meets the standards.
In short, the manufacturing of high-precision powder metallurgy parts requires coordination between multiple links. From raw materials, mold plastic cnc, process to inspection, every detail involves the quality of the parts. Mastering these manufacturing methods can promote the development of related industries and meet the needs of high-precision powder metallurgy parts in higher-end fields.
