Ukucamngca ngokuchanekileyo kwendlela yokuphefumla

Iimpawu kunye nezibonelelo
(1) Owona mda wobude bokuphosa ngama-700mm, kwaye ubude obulula bungaphantsi kwe-200mm. Ubunzima obukhulu bokuphosa bumalunga ne-100 kg, ihlala ingaphantsi kwe-10 kg.
. I-Angle i-± 0.5 ~ ~ ~ ± 2. Degrees, kunye nobuncinci bokuphosa i-windows yi-0.5 ~ 1.5mm. Ubungqingqwa bokuphosa malunga ne-RMAX 4s ~ 12s.

.
(5) Gcina inkunkuma ebonakalayo, kwaye inokuveliswa ngokobuninzi.
IIMPAWU ZOKUZIPHATHA NGOKUGQIBELA ZIYENZIWE NGEENJONGO ZE-JET, i-turbines yegesi, ii-curtin, izithuthi, oomatshini bokushicilela, oomatshini bokutya, oomatshini bokuthunga, kunye namanye amalungu otshintsho.

Zimbini iintlobo zendlela yokuphosa i-des
Indlela yokufa eqinileyo iyenza ubumba obufana nobukhulu bokugqibela wokuphononongwa emva kokuqwalaselwa kwe-shorinkini ye-shorink ye-speen kunye ne-shorinking yentsimbi. I-wax enyibilikisiweyo ithululwe kwi-mold eyenziwe ngentsimbi okanye i-silica gel. Emva kokususa uhlobo lwe-wax, thambisa i-powder kunye ne-binder. Emva kokuba iphule, itshiza i-Coarcy Recrectory kwaye yome. Faka isakhelo esikhutshiwe, gcwalisa umgubo nge-binder, kwaye ume. Emva koko tshisa ukunyibilikisa i-wax ngaphandle. Fudumeza ubumba kwiqondo lokushisa eliphezulu, tshisa inani elincinci le-wax entsha kwaye unyuse amandla ayo, emva koko bakhuphe i-bibix yentsimbi.
Indlela ye-ceramic shell de i-wax yohlobo lwe-wax iyafana nendlela eqinileyo ye-WOLD, kodwa emva kwesanti eqinileyo (okanye isanti yokuntywila), kodwa iphindaphindwe kude kube selokutyumza kunye nesanti de kube selokutyumza kunye nesanti de kube kufumaneka isilayidi. Yomile, ukufudumeza, ukunyibilikiswa kwe-wax, iqondo lobushushu elichumayo kwaye emva koko lothuke, le ndlela isetyenziswa ngokubanzi kwishishini lokuchaneka kwentliziyo, kuba inezi zinto zilandelayo:
(1) Uzinzo olufanelekileyo
(2) Ukusetyenziswa okuncinci kwezixhobo zokuphikisana
(3) Ubunzima bokukhanya, kulula ukuthwala, ukuphatha, kwaye wenze izigqibo ezinkulu
.
(5) Ixabiso lemveliso eliphantsi
.
(A) Imodeli enkosi
Ubume bemodeli ephambili iyafana nemveliso yokugqibela. I-prosages kunye ne-shrinkage ye-wax, kunye nokufudumeza kunye nokwanda kunye nokuvumelana kunye nokuntywila kwembumbulu yokuphosa kufuneka kuthathelwe ingqalelo kwisinyithi sokuphoswa. Umzekelo, xa inqanaba le-shrinkage yohlobo lwe-wax luyi-1.2%, inqanaba lokwandiswa kwe-thermal yokwanda kwe-0.7%, kunye nenqanaba lokunyusa i-italing yi-Aluminium Allow nobhedu
