PM powder metallurgy process was invented in 1973 in California, USA. It is a new form of powder metallurgy sintering that was created by integrating the fields of plastic injection molding and powder metallurgy. Powder metallurgy is similar to the injection molding process in that it starts with solid powder and organic binder mixing, then plasticizing at 150 degrees, injection mold cavity with injection molding equipment, solidifying again, then using the method of thermal decomposition of binder removal from the billet, and finishing with powder metallurgy, precision by sintering parts.Powder metallurgy compaction molding is the process of filling a mold with powder by gravity using machine pressure extrusion molding. Cold closed steel die pressing, cold isostatic pressure, hot isostatic pressure, and temperature pressure are the most extensively employed in real industrial applications. Some complex structural pieces, however, cannot be created or can only be converted into blanks due to the only up and down two-way pressing. powder metal manufacturing eliminates the need for metal removal processes to create the final goods, lowering manufacturing costs.Jiehuang is a famous powder metallurgy products company in China, Jiehuang products are sold to all countries in the world, especially to Italy, Poland, Denmark, USA, UK and other countries, please send your drawings, we will reply you immediately!
