powder injection molding - sewing machine parts

At the beginning of the development of powder metallurgy mechanical parts, sewing machine parts used to be an important market of powder injection molding parts.Because bulk sewing machine parts is bigger, bear the load of small, does not require high resistance to impact, parts size is small.In the 1950 s, Europe began to production and use of powder metallurgy parts, in the '60 s Japanese production of powder metallurgy has been adopted in most of the brands of sewing machine parts.Taiwan in 1997 sewing machine manufacturing (including export) using powder metallurgy parts is about 2145 t.It can be seen that the rapid development of powder metallurgy technology.
