Metallurgy in the process of manufacturing and processing machinery parts, its powder purchase costs and the cost of production of the various processes to conduct a comprehensive estimation, and also to determine the total cost, and to calculate the total amount of capital investment in powder metallurgy products.
Powder Metallurgy work before production of powder metallurgy products procurement. This step is very important. Under normal circumstances it is the purity of between 95% -98%, per gram of metal materials costs in the general case parts × volume × parts density raw materials procurement costs. Work after the raw material selected is pressed into powder raw material products, the cost of repression and press tonnage great. It generally includes the cost of the machine and labor costs. Presses choose the size of the product of the compacting pressure to the maximum cross-sectional area perpendicular to the direction of pressing with units is based on the different requirements of the compacting pressure is not the same, like the kind of low density products and pressure is generally
400MPa, a high density of 600 ~ 700MPa. Powder metallurgy products, required less equipment to suppress fast. Then is the control of the cost of the mold, the mold material should be selected high pressing force of the material, product specifications such repression will be more accurate. Finally, after the completion of the finishing, grinding and other details of the work.
Powder metallurgy in the manufacturing process of a total of four processes, each process will involve costs, without reducing the quality of products, reasonable control costs, has become a major consideration in the powder metallurgy products.
