Iqela le-Chengyu ngumenzi wezinto zokuvavanywa kokuchaneka. Ukuzibandakanya kwimveliso yoomatshini bokuvavanywa okuphezulu kwe-elektroniki uprounds, baxhotyiswe ngeenkqubo zokusebenza eziphezulu, ezixhomekeke kwiinkqubo zovavanyo eziphezulu zokusebenza ngokuchanekileyo zomatshini wokulawula ngomatshini wokulawula ngomatshini kwaye ufumane idatha echanekileyo. Nika iintlobo ngeentlobo zezixhobo zovavanyo, zinokwenza inconse, uxinzelelo, ukucheba kunye nolunye uvavanyo lwezinto ezenziwayo. Kuxhomekeka kwiseli yomthwalo osikiweyo, iklasi yokuchaneka inokufikelela kwi-0.5. Kubuhlobo obubekiweyo, ngaphandle kwengxolo xa izixhobo ziyasebenza.

Iqela le-Chengyu linethako lemizi-mveliso kwaye lifumene isiqinisekiso se-ISO9001. Ixhotywe ngokuphela kokuphela komatshini we-CNC enobuchule, inokuvelisa isakhelo sezixhobo zovavanyo kunye nezixhobo ezahlukeneyo. Ukusuka ekukhetheni izinto ezingafunekiyo kulo lonke unxibelelwano lwemveliso, u-Chengyu walawulwa ngokungqongqo ukuqinisekisa ukuba sinika abathengi ngeemveliso ezisemgangathweni. Ezi zixhobo zifumene indumiso ye-Unimam evela kubathengi, kwaye ithunyelwa ngaphandle eMelika, iYurophu, i-Asia i-Asia naseAfrika, njl njl. ,. I-Chengyu yi-traint ethembekileyo kumthengi oxabisekileyo.
