Resin ua ufiufi oneone sima
Sintered sima oneone o se oneone lafo spherical faafoliga atiina ae e SHXK.E maualuga le refractoriness (> 1800°C), laititi angular coefficient (<1.1, e tusa ma le spherical), maualalo le faʻaaogaina o le suka (mea e le tutusa), maualalo le faʻaogaina o mea faʻapipiʻi (30% faʻaitiitiga i totonu o mea faʻapipiʻi), ma vaega tetele o le malosi, e le motusia ma isi uiga, talafeagai mo le oneone (moulding sand, core sand) , oneone fa'apipi'i, V auala lafo, fa'amomomo leiloa ( oneone fa'atumu), fa'apipi'i fa'apipi'i (pa'u oneone sima), lomitusi 3D ma isi fa'agasologa lafo.O le oneone lanu meamata ma fa'alelei le si'osi'omaga.
O se vaega o le oneone sima o loʻo faʻaaogaina i le oneone ma le oneone autu e fai ai le atigi atigi ma le atigi fatu e iai mea totino o le maualuga o le vevela, faʻalauteleina le faʻalauteleina, paʻu faigofie, ma le maualalo o le gaosiga o le kesi, lea e mafai ona puipuia lelei le faʻalauteleina o faaletonu i castings.Mo cores e faapitoa lava foliga faigata, e mafai ona taulimaina le faafitauli o le fana oneone e le faigofie ona faʻapipiʻi.
O le oneone sima atoa o loʻo faʻaaogaina e fai ai le oneone faʻapipiʻiina, ma toe faʻaaogaina pea pe a maeʻa le toe faʻaleleia, lea e mafai ona faʻaleleia lelei le lelei ma le gaosiga o le gaosiga, faʻaitiitia le fua o le togi ma le tau o le gaosiga o pisinisi, o le tau faʻaaogaina umi e maualalo ifo nai lo lena. o oneone silica.O le mea lea, i tausaga talu ai nei, toetoe lava o laʻau oneone faʻapipiʻi tetele uma na faʻaaogaina oneone sima e pei o le oneone mata e gaosia ai le oneone.
Fa'amanuiaga
● Resin ufiufi oneone sima ma super maualuga le vevela tetee, malosi tetee i le malosi deformation, maualalo tau, evolution kasa maualalo, e ausia manaoga faapitoa o tagata faatau.
● Lelei le faʻatumuina o le malosi o le suavai, faʻapipiʻi e le faʻapipiʻi, e talafeagai mo le faʻagasologa o le faʻaogaina o le fatu.
● Tete'e maualuga maualuga vevela e mafai ona aloese mai le lafoina o faaletonu e pei o le susunuina o le oneone, gaugau luga, veining, sooga moli ma ta'e.
Fa'atatauga
Poloka pa'u afi, ulu ulu, mama piston, fa'amaufa'ailoga suau'u, puna fola.
Laiti ma feololo-tele-tele u'amea u'amea, uamea lafo atigi, off-core.
Fa'aaogaina i le tele o le turbine shell mold, 6-8 speed gearbox, vaega autu o le tisiki taofi ta'avale.
Muti-colinder poloka(gaogao le ituaiga fa'aulu autu), o le paipa ta'u ma bronchus.
Camshaft, fa'amaufa'ailoga suau'u, atigi tulimanu fagu.
O ituaiga uma o tulaga maualuga, maualuga manaʻoga, faiga faigata o le faʻafefeteina oneone castings.
Vaega o Fa'asoa Lapopo'a
E mafai ona fa'avasegaina le fa'asoaina o le lapopo'a e tusa ai ma lou mana'oga.
