V. Mabapi le Tlhahiso ea Rona Bokhabane
Sichuan Yining Mechine Equipment Co., Ltd. e thehiloe ka 2005 mme ke khamphani e ikgethileng tlhahisong le tlhahisong ya mefuta e fapaneng ya di-valve le disebediswa tse fedisitsweng tsa di-valve. Ho theosa le dilemo, re nehetswe lefapheng la di-valve mme re ikemiseditse ho fana ka dihlahiswa le ditharollo tsa boleng bo hodimo le tse sebetsang hantle ho bareki lefatsheng ka bophara.
Khamphani e 'nile ea khomarela filosofi ea khoebo ea hore "Boleng ke mookameli, boleng ke moputso oa rona", re tsitlallela ho nka boleng e le motheo le ho nka boleng ba sehlahisoa bo tsitsitseng le bo tšepahalang e le motheo o tiileng oa tšebelisano-'moho ea nako e telele le bareki. Re tseba hantle hore lihlahisoa tsa boleng bo holimo le bokhoni bo tsitsitseng ba ho fana ka thepa ke linotlolo tsa nts'etsopele e tsoelang pele ea khoebo.
Khamphani e fetile Setifikeiti sa sistimi ea taolo ea boleng ba ISO9001 le setifikeiti sa CE, mme e latela ka tieo maemo a machaba a tlhahiso le taolo ea boleng ho netefatsa hore sehlahisoa se seng le se seng se fihlela litlhoko tsa indasteri le tsa bareki.
Ka lilemo tse ngata tsa boiphihlelo ba tlhahiso le mekhoa ea tlhahiso e hōlileng tsebong, re na le sehlopha sa litsebi sa botekgeniki le sa tsamaiso se nang le tsebo e ngata ea khopolo-taba le boiphihlelo bo sebetsang. Re latela tataiso ea nts'etsopele ea "boqapi ba mohopolo, boqapi ba theknoloji, le boqapi ba tsamaiso", re ntlafatsa boleng ba sehlahisoa le tlholisano ea khoebo khafetsa.
Nakong e tlang, Sichuan Yining Machinery Equipment Co., Ltd. e tla tswela pele ho nka boleng bo botle e le motheo, ditlhoko tsa bareki e le tataiso, mme e kopane le balekane ho theha kamano ya tshebedisano mmoho ya nako e telele, e tsitsitseng le e ruisang molemo mahlakore ka bobedi.
