Powder Metallurgy Products Briefing:

—————————————————————————————————–
Sintered Oil Impregnated Powder Metallurgy Iron Flange Bushing is made by bronze or iron / stainless steel powder, mold pressed under high pressure and then sintered under high temperature, and oil is soaked into the homoeneously spreaded tiny pores of the metal under vacuum. Sintered bushing is widely used for domestic electric equipments, electirc tools, woven machines, chemical engineering machines, automobiles industry,etc.Quality standard based on JIS;DIN;GB;MPIF,etc.
