1- Kodi Chigoba cha Shell Ndi Chiyani?
Chipolopolo kuponyera amatchedwanso chisanadze TACHIMATA utomoni mchenga kuponyera, otentha chipolopolo akamaumba kuponyera kapena kuponyera pachimake. Chofunika kwambiri pachimake ndi mchenga wa phenolic wothira chisanadze, womwe umakhala wokwera mtengo kuposa mchenga wobiriwira ndi mchenga wa utomoni. Komanso, mchenga uwu sungagwiritsidwenso ntchito. Chifukwa chake, kuponyera kwa zipolopolo kumakhala ndi mtengo wapamwamba kuposa kuponyera mchenga. Komabe, Poyerekeza ndi kuponyera mchenga wobiriwira, kuponyera kwa chipolopolo kumakhala ndi zabwino zambiri monga kulolerana kwapamwamba, mawonekedwe abwino komanso zopindika zochepa. Dongosolo la kuponyera kwa chipolopolo ndiloyenera makamaka kupanga kutulutsa kwa mawonekedwe ovuta, zotengera zotengera, kulemera kwake komanso kuponyera komwe kumafuna kumaliza pamwamba.
2- Kodi Mapazi Achipolopolo Ndi Ati?
✔ Kupanga Zitsulo Zitsulo. Mchenga wa pre-lokutidwa uyenera kutenthedwa ndi kapangidwe kake, chifukwa chake chitsulo ndizofunikira popanga zida zopangira zipolopolo.
✔ Kupanga Pre-lokutidwa Mchenga Nkhungu. Pambuyo khazikitsa dongosolo zitsulo pa makina akamaumba, chisanadze TACHIMATA utomoni mchenga adzakhala anawomberedwa mu dongosolo, ndipo pambuyo Kutentha, coating kuyanika utomoni adzakhala kusungunuka, ndiye amatha kuumba mchenga kukhala olimba mchenga chipolopolo ndi mitima.
✔ Kusungunula Chitsulo Choponyera. Pogwiritsa ntchito ziwombankhanga, zinthuzo zimasungunuka kukhala madzi, kenako nyimbo zamagetsi zachitsulo ziyenera kusanthula kuti zigwirizane ndi manambala omwe amafunikira.
✔ Kutsanulira Chitsulo. Chitsulo chosungunuka chikakwaniritsa zofunikira, ndiye kuti zidzatsanulidwira mu chipolopolo. Kutengera ndi mitundu yosiyanasiyana ya mapangidwe, zipolopolozo zimayikidwa m'mchenga wobiriwira kapena kuzikongoletsa ndi zigawo.
✔ Kuwombera, Kupera ndi Kukonza. Pambuyo pakuzizira ndi kulimba kwa zoponyazo, zotuluka, zitseko kapena chitsulo chowonjezera ziyenera kudulidwa ndikuchotsedwa. Kenako kuponyera kwachitsulo kumatsukidwa ndi zida zowononga mchenga kapena makina owombera. Pambuyo pakupera mutu wa gating ndi mizere yotsalira, magawo omaliza oponyera amabwera, kuyembekezera njira zina ngati zingafunike.
3- Kodi Ubwino Wa Nkhono Kuponyera Ndi Chiyani?
✔ Zitsulo zopangidwa ndi nkhono nthawi zambiri zimakhala zolondola kwambiri kuposa mchenga.
✔ Malo osalala bwino a zomalizidwa amatha kupezeka mwa kuponyera zipolopolo.
✔ Ngodya zazing'ono zotsika kuposa kuponyedwa kwa mchenga kumafunikira kuponyera zipolopolo.
Kukhazikika kwa chipolopolo ndikokwera kwambiri chifukwa chake mpweya wocheperako kapena wocheperako umachitika.
✔ Njira zoponyera nkhungu zimafunikira mchenga wochepa kwambiri.
✔ Makina ndi otheka mosavuta chifukwa cha kukonza kosavuta kogwiritsa ntchito chipolopolo.
4- Kodi Ndizitsulo ndi Alloys Zomwe Zitha Kuponyedwa ndi Shell Mold Kuponyera Njira?
• Cast Carbon Steel: Low Carbon Steel, Medium Carbon Steel ndi High Carbon Steel kuchokera ku AISI 1020 mpaka AISI 1060.
• Osewera Zitsulo kasakaniza wazitsulo: 20CrMnTi, 20SiMn, 30SiMn, 30CrMo, 35CrMo, 35SiMn, 35CrMnSi, 40Mn, 40Cr, 42Cr, 42CrMo ... etc pa pempho.
• Osewera zosapanga dzimbiri zitsulo: AISI 304, AISI 304L, AISI 316, AISI 316L ndi ena kalasi zosapanga dzimbiri.
• Pangani Alloys Aluminiyamu.
• Mkuwa & Mkuwa.
• Zida ndi Miyezo ina mukafunsidwa
5- Ndi Zotani Zotayira Zomwe Zitha Kufikiridwa Ndi Njira Yoponyera Nkhungu?
Monga tanena mu kuponyera kulolerana kwa castings mchenga, castings chipolopolo nkhungu ndi molondola kwambiri ndi kulolerana zolimba kuposa mchenga kuponyera. Apa mu zotsatirazi ndi ambiri tolerances kalasi tikhoza kukwaniritsa ndi kuponyera wathu chipolopolo nkhungu ndipo palibe kuphika furan utomoni kuponyera mchenga:
✔ DCT grade ndi Shell Mold Casting kapena Furan resin Sand Casting: CTG8 ~ CTG12
✔ GCT grade ndi Shell Mold Casting kapena Furan resin Sand Casting: CTG4 ~ CTG7
