Muna Zvita 2020, musangano wechitanhatu wegore negore weNational Fastener Standardization Technical Committee wakaitwa muHandan City, Hebei Province. Vamiriri vanopfuura mazana maviri vakapinda musangano wegore negore, kusanganisira nyanzvi dzakawanda dzinozivikanwa muindasitiri yezvisungo kubva kumativi ese enyika, pamwe nevamiriri vemabhizinesi makuru ane simba rekugadzirisa zviyero zvepasi rose, zvemumba kana zvemaindasitiri. Mushure memusangano wegore negore. China Fastener Association yakaronga nyanzvi dzinosvika mazana maviri dzeindasitiri yezvisungo kubva kumativi ese enyika kuti vashanyire Dahe Industry uye vaone musangano wekugadzira otomatiki weDahe. Vakarumbidza zvikuru mhando yechigadzirwa cheindasitiri yeDahe, nzira yekugadzira yakangwara uye sisitimu yekuvandudza girini. Vatungamiriri vesangano vakataura kuti mamiriro aripo ekuwedzera makwikwi muindasitiri yezvisikuru zvekuboora, mhando yechigadzirwa isina kuenzana pamusika, kubuda kwezvinhu zvisina kuchengetedzeka kana kuchengetedzeka kweinjiniya, kugutsikana kwevatengi kwave njodzi huru. Sangano rinokurudzira, uye kambani ichawedzera mari yekutsvaga, kukurumidzisa zvigadzirwa zvekuvandudza, kuvandudza mhando yezvigadzirwa, musika unoramba uchiburitsa zvigadzirwa zvemhando yepamusoro, kukurudzira kukura kwakanaka kweindasitiri ye screws, panguva imwe chete inofanira kutarisisa kukura kwegirini, kuchengetedza simba nekuderedza utsi, kuchengetedzwa kwezvakatipoteredza, uye kubatanidzwa kwekuvandudzwa kwekugadzirwa, kuwana nharaunda yezvakatipoteredza uye kukura kwehupfumi. Sebhizinesi rekuenzanisa muindasitiri yewaya dzekuchera, indasitiri yeDahe ichawedzera mari mukutsvaga kwesainzi, kushandisa pfungwa yesainzi netekinoroji sesimba rinotungamira uye mhando yekuvandudza, uye kubatsira mukusimudzira kukura kwakasimba uye kwakanaka kweindasitiri yezvikamu zvakajairika.
Pamusoro pezvo, Dahe Industry, semumiriri wenhengo, yakapinda mukuvandudzwa kwemitemo yefastener, uye yakapindawo mukuongorora mitemo yenyika yakakodzera yefastener pamwe nemitemo yeindasitiri.
