China OEM desturi chuma cha pua impela kwamchakato wa kutupa uwekezaji wa wax uliopotea.
Vipengee vya aloi ya msingi wowote wa nikeli au urushaji wa chuma cha pua ni chromium, nikeli na molybdenum (au "moly"). Vipengele hivi vitatu vitabainisha muundo wa nafaka na sifa za kiufundi za utumaji na vitasaidia katika uwezo wa utumaji kukabiliana na joto, uchakavu na kutu.
Chuma cha pua kina kiwango cha chini cha chromium cha 10.5%, na kuifanya kustahimili mazingira ya kioevu babuzi na uoksidishaji. Hata hivyo, hii sio kabisa. Uwekezaji wa chuma cha puacastings "zinastahimili kutu" zinapotumika katika mazingira ya kimiminika na mivuke iliyo chini ya 1200°F (650°C) na "kinachostahimili joto" zinapotumika zaidi ya halijoto hii.
Manufaa ya Vipengele vya Uwekezaji wa Uwekezaji:
- Kumaliza bora na laini ya uso
- Uvumilivu mkali wa dimensional.
- Maumbo changamano na changamano na unyumbufu wa muundo
- Uwezo wa kutupa kuta nyembamba kwa hiyo ni sehemu nyepesi ya kutupa
- Uchaguzi mpana wa metali za kutupwa na aloi (feri na zisizo na feri)
- Rasimu haihitajiki katika muundo wa molds.
- Kupunguza haja ya machining sekondari.
- Upotevu wa chini wa nyenzo.
