Modern medical appliances are in great demand, and the structure of many medical appliances is also very sophisticated and complex, so a new manufacturing technology is needed to replace the traditional production. Nowadays, metal powder metallurgy can mass produce products with complex shapes in a short period of time, which can meet the manufacturing requirements of medical appliances and become an ideal manufacturing method. <\/p>\n\n\n\n
Metal powder metallurgy technology<\/h2>\n\n\n\n
Metal powder metallurgy is a Near Net Shape Forming process developed rapidly in the 20th century. The general process is powder + binder mixing powder metallurgy degreasing sintering.<\/p>\n\n\n\n
The first is to mix the polymer with powder to produce a feeding material with sufficient fluidity, uniform mixing and satisfying injection requirements under certain conditions. The second is to select an appropriate temperature, pressure, and speed for powder metallurgy. The second is to sinter the powder after removing the binder from the injection blank. Finally, metallurgical bonding is formed, and the required parts are obtained.<\/p>\n\n\n\n

Medical appliances manufactured by metal powder metallurgy technology<\/h2>\n\n\n\n
Medical appliances generally require good usability and long enough service life, and flexible design in structure and shape design.<\/p>\n\n\n\n
Metal powder metallurgy technology was first used in medical appliances in the early 1980s and has become the fastest-growing area of metal powder metallurgy market.<\/p>\n\n\n\n

Orthodontic bracket<\/h3>\n\n\n\n
Metal powder metallurgy technology was first used in medical treatment to produce some orthodontic appliances. These precision products are very small in size, biocompatibility and corrosion resistance. The main material used is 316L stainless steel. At present, orthodontic brackets are still the main products of metal powder metallurgy industry.<\/p>\n\n\n\n
