Xa i-wax isetyenziselwa ukwenza ipateni, ukuphosa utyalo-mali kukwabizwa ngokuba "yilahleko yokuphosa i-wax".Ukuphosa utyalo-mali ngokuqhelekileyo kubhekiselele kwiskimu sokuphosa apho imilo yenziwe kwizinto eziphathekayo, umphezulu wemilo uqatywe ngamaleko amaninzi ezinto eziphikisayo ukwenza iqokobhe lokungunda, kwaye ke ukungunda kuyanyibilika kwiqokobhe lokungunda, Ukufumana isikhunta ngaphandle kokuhlukana kwendawo, enokuthi izaliswe yisanti kwaye igalelwe emva kokushisa okuphezulu.Ukwenziwa kotyalo-mali kudla ngokubizwa ngokuba “kukulahleka kwewax” ngenxa yokusetyenziswa kakhulu kwemathiriyeli yewaksi ukwenza le pateni.

Iindidi ze-alloy eziveliswa ngokuchithwa kwe-investment yi-carbon steel, i-alloy steel, i-alloy-resistant-alloy, i-stainless steel stainless, i-alloy echanekileyo, i-alloy yamagnetic esisigxina, i-bearing alloy, i-alloy yobhedu, i-aluminium alloy, i-titanium alloy kunye ne-nodular cast iron, njl.

Ngokuqhelekileyo, imilo yotyalo-mali inzima kakhulu.Ubungakanani obuncinci bomngxuma wokuphosa unokufikelela kwi-0.5mm, kwaye ubuncinci bendonga yodonga lwe-0.3mm.Kwimveliso, amanye amacandelo ekuqaleni aqulunqwe ngamacandelo amaninzi anokuthi ayilwe ngokupheleleyo kwaye afakwe ngokuthe ngqo ngokuchithwa kotyalo-mali ngokutshintsha ulwakhiwo lwamacandelo, ukwenzela ukuba kugcinwe iiyure zokusebenza kunye nokusetyenziswa kwezinto zetsimbi, ukwenzela ukuba ukwakhiwa kwamacandelo isengqiqweni ngakumbi.

Uninzi lobunzima botyalo-mali luvela kwi-zero ukuya kwi-newtons eninzi (ukusuka kwiigram ezimbalwa ukuya kwishumi elinesibini leekhilogram, ngokuqhelekileyo akukho ngaphezu kwe-25 kilograms).Kuyingxaki ukusebenzisa utyalo-mali ukuvelisa izinto ezinzima.

Inkqubo yokuphosa utyalo-mali inzima, kwaye akulula ukuyilawula, kwaye izinto ezisetyenzisiweyo kunye nezisetyenzisiweyo zibiza kakhulu.Ke ngoko, ilungele ukuveliswa kwamalungu amancinci aneemilo ezintsonkothileyo, iimfuno ezichanekileyo ezichanekileyo, okanye obunye ubunzima bokucwangcisa, obunje ngeenjini ze-injini yomoya.
