Dulqaadka cabbirku waa arrin muhiim ah marka aan dooranno habka wax shubidda ee jilitaanka la rabo. ISO 8062 (oo u dhiganta GB/T6414-1999 ee Shiinaha GB) dukumeentiyada caadiga ah, heerarka dulqaadka ee cabbirada tuurista ayaa si cad loo qeexay. Guud ahaan marka la hadlo, dhiibista maalgelinta iyo tuurista dhinta waxay leeyihiin saxnaanta sare ee cabbirka waana sababta habka maalgelinta loo yaqaantuurista saxda ah. Halkan kuwan soo socda waxa aad ku arki doontaa dulqaadka guud ee kabka ee hababka wax tuurista ee kala duwan.

U dulqaadashadaCastings ciid
Dulqaadyada kabka waxa loo qaybiyaa Dulqaadashada Qaadashada Cabbirka (DCT) iyo Dulqaadyada Qaadashada Joomatari (GCT). Aasaaskayagu wuxuu jeclaan lahaa inuu kula hadlo haddii aad hayso codsi gaar ah oo ku saabsan dulqaadka loo baahan yahay. Halkan kuwan soo socda ayaa ah darajada dulqaadka guud ee aanu ku gaadhi karno tuurista ciidda cagaaran, shubista caaryada qolofka ah iyo shubista ciidda xabagta furan ee aan la duban:
- ✔ Darajada DCT ee Cagaar Cagaar Kaabista: CTG10 ~ CTG13
- ✔ Darajada DCT ee Shell Mold tuurista ama Kaabista Ciidda Furan Resin Ciid: CTG8 ~ CTG12
- ✔ Fasalka GCT ee Cagaaran Sand Casting: CTG6 ~ CTG8
- ✔ GCT darajada by Shell Mold tuurista ama Furan Resin Ciid tuurista: CTG4 ~ CTG7
U dulqaadashadaMaalgelinta Maalgashiga
Marka loo eego agabka wax-ku-xidhaha ee kala duwan ee loo isticmaalo samaynta qolofka, shubista maalgelinta waxa loo qaybin karaa shubka silica iyo shubista dhalada biyaha. Habka shubista silica sol ayaa leh dulqaadka Cabbiraadda Cabbiraadda (DCT) iyo Dulqaadyada Qaadashada Joomatari (GCT) ka wanaagsan habka dhalada biyaha. Si kastaba ha ahaatee, xittaa iyadoo la raacayo habka wax- shubista, Darajada Dulqaadku waxa ay ka duwanaan doontaa wax kasta oo kabka ah sababtoo ah awooddooda kala duwan. Aasaaskayagu wuxuu jeclaan lahaa inuu kula hadlo haddii aad hayso codsi gaar ah oo ku saabsan dulqaadka loo baahan yahay. Halkan kuwan soo socda ayaa ah darajada dulqaadka guud ee aynu ku gaadhi karno labadaba silica sol iyo hababka shubista dhalada biyaha si gooni gooni ah:
- ✔ Darajada DCT ee Silica Sol Lost Wax tuurista: DCTG4 ~ DCTG6
- ✔ Darajada DCT ee Dhalada Biyaha ee Dhuxul Tuuray: DCTG5 ~ DCTG9
- ✔ GCT Grade by Silica Sol Lost Wax tuurista: GCTG3 ~ GCTG5
- ✔ Darajada GCT ee Dhalada Biyaha Dhuxul tuurista: GCTG3 ~ GCTG5
Dulqaadashada Dulqaadyada Ku-Xidashada Caaryada Shell
Sida aan ku soo sheegnay dulqaadka tuurista ciid tuurista, tuurista caaryada qolofku waxay leeyihiin saxnimo aad uga sareysa iyo dulqaad adag marka loo eego ciid tuurista. Halkan kuwan soo socda ayaa ah darajada dulqaadka guud ee aanu ku gaadhi karno tuurista caaryadayada qolofka ah iyo tuurista ciidda xabagta furan ee aan la duban:
- ✔ Darajada DCT ee Shell Mold tuurista ama Kaabista Ciidda Furan Resin Ciid: CTG8 ~ CTG12
- ✔ GCT darajada by Shell Mold tuurista ama Furan Resin Ciid tuurista: CTG4 ~ CTG7
Dulqaadashada Dulqaadashada Xumbo lumin ee
Guud ahaan marka loo hadlo, dulqaadka tuurista xumbo tuurista ee luntay ayaa ka wanaagsan tuurista ciidda, laakiin waxaa ka sii daran shubista qolofka iyo hababka shubista aan dubitaanka lahayn. Aasaaskayaga, waxaan asal ahaan ku guulaysan karnaa darajooyinka soo socda Laakiin waxaan jeclaan lahayn inaan kaala hadalno jilayaasha gaarka ah ka dibna go'aan ka gaarno lambarada aan ku siin karno.
- ✔ Darajada DCT by tuurista xumbo lumay: CTG9 ~ CTG13
- ✔ Darajada GCT ee tuurista xumbo lumay: CTG5 ~ CTG8
Haddii dukumeentiga sawirka ama habka shubista uu si cad ugu baahan yahay in la eego dhammaan cabbirrada wax shubidda, dhammaan cabbirrada wax shubista waxay u baahan yihiin in la eego. Xaaladdani inta badan waa qaybta koowaad ee wax-soo-saarka kabka ama habka baadhista muunada randomka inta lagu jiro wax-soo-saarka guud. Wax-soo-saarka dufcaddii yar-yar, waxaa mararka qaarkood loo baahan yahay in la kormeero dhammaan cabbirrada wax-shubashada.
Iyada oo la raacayo shuruudaha lagu qeexay sawirada ama dukumentiyada nidaamka, cabbirada wax lagu shubayo waxay u baahan yihiin in lagu eego cabbirada xakamaynta muhiimka ah, cabbirrada leh shuruudaha saxsanaanta sare, iyo cabbirrada si fudud u qalloocan oo ka baxsan dulqaadka. Xaaladdan waxaa badanaa lagu dabaqaa kormeerka kantaroolka ee cabbirrada wax soo saarka ballaaran ee khadka wax soo saarka.
