Ndi kukana kubowola, mtengo wokwera, kugwira bwino, kosavuta kutsetsereka, kutopa kwambiri, komanso kugwira bwino ntchito. Mawilo a PU monga amodzi mwa ma casters omwe amagwiritsidwa ntchito kwambiri, ali ndi makhalidwe awa:
1. Kukana kwamphamvu kwa kukanda: chinthu chachikulu chomwe chimagwiritsidwa ntchito ndi gudumu la PU, polyurethane, chili ndi kukana kwamphamvu kwa kukanda, ndipo chingagwiritsidwe ntchito m'malo osiyanasiyana a nthaka, kuphatikizapo simenti, pansi pamatabwa, makapeti, pulasitiki, ndi zina zotero, ndi ntchito zosiyanasiyana.
2. Phokoso lochepa: Poyerekeza ndi mawilo a rabara achikhalidwe, mawilo a PU amatulutsa phokoso lochepa paulendo, zomwe zingachepetse kusokoneza kwa phokoso la chilengedwe kwa anthu.
3. Kukana bwino kukanikiza: Mawilo a PU ali ndi kukana kwakukulu kukanikiza, amatha kupirira kulemera kwakukulu, ndipo sakhala osavuta kupotoza akanyamula katundu wolemera, kotero angagwiritsidwe ntchito ngati zida ndi zida zomwe zimafunika kupirira katundu wolemera.
4. Kukana dzimbiri: Malo a gudumu la PU si osavuta kutenthedwa ndi dzimbiri komanso okosijeni, ngakhale atagwiritsidwa ntchito pamalo ozizira sadzakhudza magwiridwe ake, kotero ndi oyenera kugwiritsidwa ntchito m'malo osiyanasiyana ogwirira ntchito.
5. Kutanuka kwambiri: Mawilo a PU ali ndi kutakasuka kwakukulu, kotero amatha kuyenda momasuka pamalo osiyanasiyana, kupewa kugwedezeka ndi kugwedezeka komwe kumachitika chifukwa cha kugwedezeka kwa pamwamba pa msewu, zomwe zimapangitsa kuti chitonthozo ndi chitetezo chikhale bwino.
6. Mtengo wotsika wokonza: Mawilo a PU ali ndi mtengo wotsika wokonza poyerekeza ndi ma caster opangidwa ndi zinthu zina, chifukwa nsaluyo ndi yolimba, si yosavuta kuvala komanso kuwonongeka, kotero imatha kuchepetsa kuchuluka kwa nthawi ndi mtengo wosinthira mawilo.

Chifukwa cha mawonekedwe a zinthu za PU, ma JOYAL manganese steel casters amagwiritsanso ntchito zinthu za PU ngati zinthu zogwirira ntchito pamwamba pa gudumu mu 21 Ideal Heavy Duty Curved Surface Iron Core, 21G Ideal Heavy Duty Flat Iron Core, 22F Innovative Curved Surface Heavy Duty Precision Iron Core, 22G Innovative Flat Heavy Duty Precision Iron Core, 24 Zhitai Ultra-Heavy Duty Urethane, ndi zinthu ziwiri za Powerful Iron Core Urethane, ndi zina zotero.
