Ukunyamezelwa kokuCasa ngeeNkqubo ezahlukeneyo zokuCasa

Unyamezelo lweDimensional luyinto ebalulekileyo xa sikhetha inkqubo yokuphosa kwi-castings efunwayo. Kwi-ISO 8062 (ehambelana ne-GB/T6414-1999) yaseTshayina) amaxwebhu asemgangathweni, amanqanaba okunyamezelana kwemilinganiselo yokuphosa acaciswe ngokucacileyo. Ngokubanzi, utyalo-mali kunye nokuphosa ukufa kunokuchaneka okuphezulu kwinqanaba kwaye yiyo loo nto inkqubo yotyalo-mali ikwabizwa ngokuba.ukuphosa ngokuchanekileyo. Apha koku kulandelayo uya kubona ukunyamezelwa ngokubanzi kwee-castings ngeenkqubo ezahlukeneyo zokuphosa.

Ukuphosa UkunyamezelaUkufakwa kweSanti

Ukunyamezela ukuphosa kwahlulwe kwi-Dimensional Casting Tolerances (DCT) kunye neGeometrical Casting Tolerances (GCT). Isebe lethu lingathanda ukuthetha nawe ukuba unesicelo esikhethekileyo malunga nonyamezelo olufunekayo. Apha koku kulandelayo kukho ibakala lokunyamezelana ngokubanzi esinokufikelela kulo ngokugatywa kwesanti eluhlaza, ukubunjwa kweqokobhe kunye nokugaywa kwesanti ye-furan resin:

• ✔ IBanga le-DCT nge-Green Sand Casting: CTG10 ~ CTG13
• ✔ IBanga leDCT ngeShell Mold Casting okanye iFuran Resin Sand Casting: CTG8 ~ CTG12
• ✔ IBanga le-GCT ngeSanti yeGreen Casting: CTG6 ~ CTG8
• ✔ IBanga le-GCT ngeShell Mold Casting okanye iFuran Resin Sand Casting: CTG4 ~ CTG7

 

Ukuphosa UkunyamezelaInvestment Castings

Ngokwezixhobo ezahlukeneyo zokubopha ezisetyenziselwa ukwenza iqokobhe, utyalo-mali lunokwahlulwa lube yi-silica sol casting kunye neglasi yamanzi. Inkqubo yokuphosa i-silica sol ine-Dimensional Casting Tolerances (DCT) kunye neGeometrical Casting Tolerances (GCT) kunenkqubo yeglasi yamanzi. Nangona kunjalo, nangenkqubo efanayo yokuphosa, iBanga loNyamezelo liya kwahluka kwi-alloy nganye ngenxa yokwahluka kwazo. Isebe lethu lingathanda ukuthetha nawe ukuba unesicelo esikhethekileyo malunga nonyamezelo olufunekayo. Apha koku kulandelayo kukho ibakala lokunyamezelana ngokubanzi esinokufikelela kuzo zombini nge-silica sol casting kunye neenkqubo zokugalela iglasi yamanzi ngokwahlukeneyo:

• ✔ IBanga leDCT nguSilica Sol Lost Wax Casting: DCTG4 ~ DCTG6
• ✔ IBanga leDCT ngeGlasi yaManzi iLast Wax: DCTG5 ~ DCTG9
• ✔ IBanga le-GCT nguSilica Sol Lost Wax Casting: GCTG3 ~ GCTG5
• ✔ IBanga le-GCT ngeglasi yaManzi iLast Wax Casting: GCTG3 ~ GCTG5

 

Ukunyamezelana kokuphosa kwi-Shell Mold Castings

Njengoko sichazile kunyamezelo lokugalelwa kwesanti, ukubunjwa kweqokobhe kunokuchaneka okuphezulu kakhulu kunye nokunyamezelana okungqongqo kunokuphosa isanti. Apha koku kulandelayo kukho ibakala lokunyamezelana ngokubanzi esinokufikelela kulo ngokubunjwa kweqokobhe lethu kunye nokugalelwa kwesanti ye-furan resin:

• ✔ IBanga leDCT ngeShell Mold Casting okanye iFuran Resin Sand Casting: CTG8 ~ CTG12
• ✔ IBanga le-GCT ngeShell Mold Casting okanye iFuran Resin Sand Casting: CTG4 ~ CTG7

 

Ukuphosa Ukunyamezela kwiiNdawo eziLahlekileyo zegwebu

Ngokuqhelekileyo, ukunyamezela ukuphosa kokuphoswa kwegwebu elilahlekileyo kungcono kunokuphosa isanti, kodwa kubi kakhulu kunokubunjwa kweqokobhe kunye neenkqubo zokuphosa. Kwisiseko sethu, sinokufikelela kula mabakala alandelayo. Kodwa singathanda ukuthetha nawe ngeecastings ezithile kwaye emva koko sithathe isigqibo sokuba ngawaphi amanani esinokukubonelela ngawo.

• ✔ IBanga le-DCT ngokuphosa ugwebu olulahlekileyo: CTG9 ~ CTG13
• ✔ IBanga le-GCT ngokuphosa ugwebu olulahlekileyo: CTG5 ~ CTG8

Ukuba umzobo wokuphosa okanye uxwebhu lwenkqubo yokuphosa lufuna ngokucacileyo ukuhlolwa kwayo yonke imilinganiselo yokuphosa, yonke imilinganiselo yokuphosa kufuneka ihlolwe. Le meko idla ngokuba yinxalenye yokuqala yokuveliswa kwee-castings okanye inkqubo yokuhlola isampuli ngokungahleliwe ngexesha lokuvelisa ngobuninzi. Kwimveliso yebhetshi encinci, ngamanye amaxesha kuyafuneka ukuba kuhlolwe yonke imilinganiselo yokuphosa.

Ngokuhambelana neemfuno ezichazwe kwimizobo okanye kumaxwebhu enkqubo, imilinganiselo ye-castings kufuneka ihlolwe imilinganiselo yolawulo oluphambili, imilinganiselo eneemfuno ezichanekileyo ezichanekileyo, kunye nemilinganiselo ekhubazekayo ngokulula kunye nokunyamezela. Le meko idla ngokusetyenziswa ekuhloleni ulawulo lwemilinganiselo yemveliso ngobuninzi kumgca wemveliso.
