Yenza yangasese isihlalo ngundo ngundo intsimbi ukukhetha kuqala, ngokwenene ukufumana imveliso ngundo, inkampani Leiao ivelisa ezikrelekrele isivalo isivalo ngundo jikelele usebenzisa PP okanye ABS izinto, ukungunda umphezulu ukugqiba iphezulu, akanakuba fly side burr, intsimbi eSweden s136 okanye Japan I-Datong NAK80 intsimbi, ukuchaneka kwendibano yemveliso kuphezulu kakhulu, kufuneka kusetyenziswe umatshini wokusila onesantya esiphezulu nkqu ne-5 axis high-speed milling processing.Kodwa ngcono ukungunda, ukuphakama kweemfuno zokugcinwa, Thatha i-mold ye-TOTO yaseJapan ye-TOTO eveliswa ngumbumba wethu weLeiao. kunye nePanasonic njengomzekelo, ukungunda kwesihlalo sendlu yangasese ekrelekrele esetyenziselwa ixesha elide ngaphandle kokugcinwa okuchanekileyo, ukugcinwa okufanelekileyo kokungunda xa kuthelekiswa nokungunda okungahambiyo, kunokufumana ubomi obude benkonzo, inqanaba elisezantsi lokusilela kunye nemveliso ephezulu yemveliso, yokubumba imveliso yokubumba ishishini yindlela esebenzayo kakhulu yokunciphisa iindleko, ukwandisa ukusebenza kakuhle.
