1. Malinga ndi malo ogwiritsira ntchito
a.Posankha chonyamulira mawilo choyenera, chinthu choyamba kuganizira ndi kulemera kwa chonyamulira mawilo. Mwachitsanzo, m'masitolo akuluakulu, m'masukulu, m'zipatala, m'nyumba zamaofesi ndi m'mahotela, pansi pake ndi pabwino, posalala ndipo katundu wonyamulidwa nthawi zambiri amakhala wopepuka, zomwe zikutanthauza kuti chonyamulira chilichonse chimanyamula pafupifupi 10 mpaka 140kg. Chifukwa chake, njira yoyenera ndi chonyamulira mawilo chopangidwa pogwiritsa ntchito njira yopondaponda pa mbale yopyapyala yachitsulo (2-4mm). Mtundu uwu wa chonyamulira mawilo ndi wopepuka, wosinthasintha, komanso wopanda phokoso.
b.M'malo monga mafakitale ndi malo osungiramo katundu komwe katundu amanyamulidwa pafupipafupi ndipo katunduyo ndi wolemera kwambiri (280-420kg), tikukulangizani kugwiritsa ntchito chonyamulira mawilo chopangidwa ndi mbale yachitsulo yokhuthala ya 5-6mm.
c.Ngati imagwiritsidwa ntchito ponyamula zinthu zolemera kwambiri monga zomwe zimapezeka m'mafakitale opanga nsalu, mafakitale a magalimoto, kapena mafakitale amakina, chifukwa cha katundu wambiri komanso mtunda wautali woyenda, chotengera chilichonse chiyenera kukhala ndi mphamvu yonyamula 350-1200kg, ndipo chipangidwe pogwiritsa ntchito chonyamulira mawilo achitsulo cha 8-12mm makulidwe. Chonyamulira mawilo chosunthika chimagwiritsa ntchito chonyamulira mpira, ndipo chonyamulira mpira chimayikidwa pa mbale yapansi, zomwe zimathandiza kuti chonyamuliracho chinyamule katundu wolemerayo pamene chikusungabe kusinthasintha kosinthasintha komanso kukana kugunda. Tikupangira kugwiritsa ntchito mawilo a chonyamulira opangidwa ndi nayiloni yolimbikitsidwa (PA6) super polyurethane kapena rabara yochokera kunja. Kutengera zosowa zinazake, imathanso kupakidwa galvanized kapena kupopedwa ndi mankhwala oletsa dzimbiri, komanso kupatsidwa kapangidwe koteteza kuzungulira.
d.Malo apadera: malo ozizira komanso otentha kwambiri amachititsa kuti zinthu zotenthazi zikhale zovuta kwambiri, ndipo kutentha kwambiri, tikupangira zinthu zotsatirazi.

· kutentha kwambiri pafupi kapena kupitirira 230℃: ma casters apadera ozungulira osatentha
2. Malinga ndi mphamvu yonyamula
Posankha mphamvu yonyamula katundu wa ma caster, ogwiritsa ntchito ayenera kuganizira za chitetezo chapadera. Timagwiritsa ntchito ma caster omwe amagwiritsidwa ntchito kwambiri ngati chitsanzo, ngakhale kuti zisankho ziyenera kupangidwa kutengera njira ziwiri zotsatirazi:
a.Ma casters atatu okhala ndi kulemera konse: Chimodzi mwa ma casters chiyenera kuyikidwa. Njira iyi ndi yoyenera kugwiritsidwa ntchito pamene ma casters ali ndi mphamvu zambiri pa nthaka yoipa akamasuntha katundu kapena zida, makamaka pa kulemera konse kwakukulu komanso kolemera.
b.Ma casters 4 okhala ndi kulemera konse kwa 120%: Njira iyi ndi yoyenera pa nthaka yabwino, ndipo mphamvu ya ma casters ndi yochepa panthawi yoyendetsa katundu kapena zida.
c.Werengerani mphamvu yonyamulira: kuti muwerenge mphamvu yonyamulira yomwe ikufunika kwa oponya, ndikofunikira kudziwa kulemera kwa zida zotumizira, kuchuluka kwa katundu ndi chiwerengero cha mawilo a oponya ndi oponya omwe agwiritsidwa ntchito. Mphamvu yonyamulira yomwe ikufunika pa gudumu la oponya kapena oponya imawerengedwa motere:
T= (E+Z)/M×N
---T = kulemera kofunikira pa gudumu la caster kapena caster
---E = kulemera kwakukulu kwa zida zotumizira
---Z= katundu wolemera kwambiri
---M= chiwerengero cha mawilo a caster ndi ma caster omwe agwiritsidwa ntchito
---N = Chitetezo (pafupifupi 1.3 - 1.5).
Ndikofunika kusamala kwambiri pamene ma caster adzakhudzidwa kwambiri. Sikuti caster yokha yomwe imatha kunyamula katundu wambiri iyenera kusankhidwa, komanso zipangizo zotetezera zomwe zapangidwa mwapadera ziyenera kusankhidwa. Ngati pakufunika brake, ma caster okhala ndi mabuleki amodzi kapena awiri ayenera kusankhidwa.
