Ubwino wazinthu, mtengo wazogulitsa ndi ntchito zogulitsa pambuyo pa malonda ndizinthu zitatu zofunika kuziganizira pankhani yogula chiller chamadzi am'mafakitale chosindikizira cha laser. Wopereka madzi oundana m'mafakitale omwe ali ndi ntchito yabwino pambuyo pogulitsa amatha kuyankha mafunso kuchokera kwa ogwiritsa ntchito mwachangu kwambiri, monga S&A Teyu. S&A Teyu imapereka zowotchera madzi m'mafakitale apamwamba komanso ntchito yofulumira yogulitsa pambuyo pogulitsa ndi chitsimikizo chazaka ziwiri kuti ikwaniritse zosowa zamakasitomala osiyanasiyana.
Pankhani yopanga, S&A Teyu adayika zida zopangira yuan yopitilira miliyoni imodzi, kuwonetsetsa kuti njira zingapo zimachokera kuzinthu zazikuluzikulu (condenser) za mafakitale oziziritsa kukhosi mpaka kuwotcherera kwachitsulo; ponena za mayendedwe, S&A Teyu yakhazikitsa malo osungiramo katundu m'mizinda ikuluikulu ya China, atachepetsa kwambiri kuwonongeka chifukwa cha mayendedwe akutali a katunduyo, komanso kuwongolera magwiridwe antchito; pankhani ya pambuyo-malonda utumiki, nthawi chitsimikizo ndi zaka ziwiri.
