These new technologies, the emergence of new technology to solve the short-flow low-cost powder metallurgy materials forming problems, greatly contributed to the rapid development of powder metallurgy parts. Currently, powder metallurgy parts manufacturing technology development is to increase density, reduce costs and complexity of high-precision near net shape parts mouth.In 2000, Germany’s Fraunhofer Institute has developed one of these are known as the flow temperature and pressure of the short process of low-cost e https://npfinancials.com.au/near-net shape technology. The temperature and pressure process technology-based and combines the advantages of metal injection molding technology. By improving the mobility of mixed powders, filling ability and formability, can 😯 ~ 130 , in the traditional press on the precision forming of parts with complex geometries, such as the vertical direction with a groove with the suppression of the hole and threaded hole and other parts. 2 without the need for subsequent machining. Flow temperature and pressure forming technology not only to overcome the traditional powder metallurgy forming a complex geometry in the gaps, but also avoid the high cost of metal injection molding technology is a great potential of new technology, has a very broad application prospects.Flow temperature and pressure forming a new type of powder metallurgy parts, as near net shape technology, its main features can be summarized as follows: 1) forming parts with complex geometry flow using temperature and pressure can be directly formed with grooves perpendicular to the direction of repression, holes and screw holes and other parts, while the use of the shape of the cold manufacture of such parts is very difficult or even impossible, manganese powder the general need to complete the subsequent machining, CNC press to realize that the use of complex and precise movements , can only produce a relatively simple type of parts. Fraunhofer researchers used a special mold, the T-hole, hole, L-shaped cavity mold hole has been studied and successfully prepared a T-shaped parts. The results show that the well-mixed powder flow is sufficient to avoid cracks in the corner. Fraunhofer researchers have also used the shape with a slight taper to successfully direct the punch forming a deep blind hole parts, blind holes and wall thickness of the high rate of up to 3 to 7, the changes in wall thickness in the range of 1 ~ 3mm . Flow temperature and pressure can also be precision ground forming threaded holes. With the external thread of the bolt with a core mold after compaction, it will tighten the b
