ukubika indalama mu fya ndalama;

Ilyo mulebomfya ifipe fya wax, ukufushako ukusunguluka kwaishibikwa nga "ukubika umusambo uwaonaika"} Ukufumya ifipe ifyakupangapanga ilingi line kulosha ku cipe cakufushishamo icapangwa ku fipe ifyasunguluka, ukufimba ifiputulwa ifingi ifya fipe pa cifulo, elyo no kusungulula icikope no kusungulula icibumba, pakuti bafumyepo ifipe, nokufungula ifyakupangapanga, nokufukula umusenga pa numa ya kulwa no kulwa. ukupanga, eico ukusunguluka kwa kusunguluka ilingi line kwitwa "ukupoosa kwa wax ukwaonaikakwete(2{2}}
Ukubika ifipe pa nshi na kabili kwaishibikwa nga inshila iyaonaika iya wax iyaonaika, ni nshila ya kuloba iya wax, kabili lyena pa cipe icakakilwe ica matololo, ici e ciputulwa ca matope {1 Pa numa ya cipimfya ca matope, iciko mu cipe ca cemo_2}, ukusha umubutu, ukushika fye umuti, ukusha umufuba, umufuba fye uwabipa, umufuba wa mu nkumbabulili, umufuba wa mu nkumbabulili. umulomo washala, kabili lyene amenshi ya mukuba yapongolwelwa ukufuma ku kanwa[4}} Pa numa ya kutonsha, ifipe fyafwaikwa fyapangwa(5)}}
Imisango ya aoloy iyo ingapangwa ukupitila mu kusunguluka kwa kupanga umubili ni carbon, ifyuma ifya cela, ifya cela ifyashipikisha ukukaba, ifya cimuti ifyabula bwino, ifya cine cine, ifya kulya ifya muyayaya, ifya kulya ifya mukuba, ifya mukuba, amafuta ya mu mukuba, ifya kulya ifya mu mubili, na fimbi
Ukupanga imisango ya kusunguluka:
{0{4} Ukupima ifintu (mu cituntulu ne fintu fya wax, ifya cifyalilwa ifya cifyalilwa na pulasitiki (inshila ya kupanga))
{0{4} Ukupekanya no kubwesha ifipe fya nkumba .
{0{4}} Ukupanga ifipuupu ifyasunguluka ne fiputulwa
Ukupanga ifya kufwala ifya musango
{0{0}} Ifyakubomfya ku kupanga icakufwala ica musango
Ifintu ifyaonaula: ifipimo fya mubili ne fya mu kati, pamo pene no bukali bwa aluminiamu, pamo nga ububumba bwa alumm, impanga ya alumin, amabwe, na fimbi ifya ku mubili, na kabili kabili inshita shimo na zzorin, ubusungu (MgO), na fimbi};
Binder: silicic acid colloid solution, simply silica acid sol, such as ethyl silicate hydrolysate, water glass, and silica sol. Water glass shell is easy to deform, crack, with the casting size accuracy and surface smoothness are poor, the stability of silicon sol is good, can be stored for a long time, the shell without special hardening agent, but the silica gel on ukutonsha umufuba wa kusunguluka takwabako panono, inshila ya kukoshamo ifipe ni nshila ya kuumishishamo, ilakabila inshita iikalamba .
