Ndi chitukuko chachangu cha ukadaulo, njira yamakono yodulira ulusi wa laser yalowa m'malo mwa njira yachikhalidwe. Makina odulira ulusi wa laser, monga njira yotchuka kwambiri yodulira m'zaka za m'ma 2000, ayambitsidwa m'mafakitale ena ambiri chifukwa chogwirizana kwambiri ndi zipangizo zosiyanasiyana komanso ntchito yamphamvu. Ponena za dera lodulira zitsulo, makina odulira ulusi wa laser ndiye osewera akuluakulu, omwe amapanga 35% ya makina onse odulira. Makina odulira amphamvu otere amafunikanso kuziziritsidwa ndi choziziritsira madzi chozizira mpweya kuti chigwire ntchito bwino kwambiri.
Bambo Andre ochokera ku Ecuador ndi manejala wogula kampani yomwe imapanga makina odulira ulusi wa laser pomwe IPG 3000W fiber laser imagwiritsidwa ntchito ngati gwero la laser. Pofuna kuziziritsa ma fiber laser awa, Bambo Andre kale adagula ma air cooled water chillers ochokera ku mitundu itatu yosiyanasiyana kuphatikiza S&A Teyu. Komabe, popeza ma air cooler amadzi ozizira a mitundu ina iwiri ndi akuluakulu ndipo amatenga malo ambiri, kampani yake sinawagwiritse ntchito pambuyo pake ndipo adayika S&A Teyu pamndandanda wa ogulitsa kwa nthawi yayitali chifukwa cha kukula kwake kochepa, mawonekedwe ake ofewa komanso magwiridwe antchito okhazikika oziziritsira. Masiku ano, makina ake odulira laser onse ali ndi ma air cooled water chillers a S&A Teyu CWFL-3000.
Ponena za kupanga, S&A Teyu yayika zida zopangira zopitilira RMB miliyoni imodzi, kuonetsetsa kuti njira zosiyanasiyana zikuyenda bwino kuyambira pazigawo zazikulu (condenser) za chiller cha mafakitale mpaka kulumikiza zitsulo; pankhani ya mayendedwe, S&A Teyu yakhazikitsa malo osungiramo katundu m'mizinda ikuluikulu ya China, zomwe zachepetsa kwambiri kuwonongeka komwe kumachitika chifukwa cha mayendedwe ataliatali a katundu, komanso kukonza bwino mayendedwe; pankhani ya ntchito yogulitsa pambuyo pogulitsa, nthawi ya chitsimikizo ndi zaka ziwiri.
