YUANKY tau pib txij li xyoo 1989, uas muaj cov khoom zoo, tus nqi sib tw thiab kev pabcuam zoo heev hauv lo lus. Qhov chaw tsim khoom ntawm txhua yam khoom siv carbon, suav nrog tsheb, maus taus txhuam thiab txhuam sib dhos, cov cuab yeej hluav taws xob txhuam, cov khoom siv hauv tsev txhuam, muaj traction motor txhuam, tsheb ciav hlau txhuam, lub cev muaj zog slipping nplhaib, carbon-graphite lossis high-purity graphiteseal nplhaib thiab sai sai.

Cov khoom tsis yog tus qauv ntawm ntau yam qauv tuaj yeem tsim thiab tsim raws li cov neeg siv khoom tshwj xeeb.

Raws li lub Hoobkas tsim, peb muaj cov txheej txheem siab thiab fabrication, advanced equipments tshwj xeeb rau kev tsim thiab kev sim, ib pab kws tshaj lij engineer uas muaj kev paub ntau yam hauv kev tsim thiab tsim tau ntau xyoo.

Peb ib txwm hais rau "Zoo yog thawj zaug, Kev ncaj ncees yog lub hauv paus" raws li lub ntsiab lus ntawm peb lub Hoobkas, thiab peb tau muaj kev paub ntau yam rau cov khoom siv roj carbon monoxide thiab lub hom phiaj ua lub hom phiaj sab saum toj.
