What are the benefits of powder metallurgy processing
Powder metallurgy is a kind of near-net molding technology, at present the application of powder metallurgy has been very wide, like our life in the cell phone spare parts, computer spare parts, home appliances spare parts and other precision spare parts are made of powder metallurgy processing technology. But some people for the rise of powder metallurgy new technology is not quite understand, more inclined to the traditional processing technology.

Metal parts processing has a variety of molding processing technology, which mim powder metallurgy processing in the cell phone parts on the application of more. mim powder metallurgy injection molding technology is the modern plastic injection molding technology and traditional powder metallurgy process combined with the formation of a new type of powder metallurgy near-net molding technology. Cell phone parts mim powder metallurgy parts products with high dimensional accuracy (± 0.1% ~ ± 0.5%), good surface finish (roughness 1 ~ 5μm), and very large output.
The next Harber Metal Factory will give you a specific talk about the benefits of powder metallurgy processing:
1. Special materials can be processed. Refractory metals and compounds, false alloys and porous materials can be processed by powder metallurgy.
2. As powder metallurgy can press the finished size, there is no need for re-processing. Only 1% of the metal loss in this method occurs during processing, saving raw materials and reducing production costs.
3. In the process of powder metallurgy, the material does not melt, does not mix with other material impurities, is sintered in a vacuum and reducing atmosphere, does not oxidize, and does not contaminate the material. So the products are of high purity.
4. Powder metallurgy is suitable for various products with uniform shape, such as gears. Its processing cost is high, and it can be mass-produced, which greatly reduces the production cost.
Powder metallurgy processing technology is to use some metal powder as raw materials, through a series of mold pressing molding or injection molding to form the corresponding shape of the product, and then through the sintering to increase the performance and some post-processing, it forms the final powder metallurgy processed products, high precision, good performance, high efficiency, and complex parts can also be processed in mass production.
Powder metallurgy processing technology breaks through the traditional processing technology can not break through the technical difficulties, so that the production and processing of precision parts efficiency, accuracy, cost is more advantageous, similar to some of the porous, vibration isolation, bimetallic composite materials, shaped complex materials, etc., not only high-efficiency mass production, but also the direct production of high-precision products, less cutting or no-cutting machining, the utilization of materials is up to 95%, processing Fewer work processes, greatly reducing production costs.
