M'modzi mwa makasitomala athu, Mr. Zhang omwe amapanga makina osindikizira a laser flying ink-jet, makina osindikizira a UV laser inki-jet ndi makina osindikizira a CO2 RF laser inki-jet makamaka amagwiritsa ntchito ma lasers otsatirawa, kuphatikizapo Iradion laser, Synrad laser ndi Rofin laser.
Masiku angapo apitawo, Mr. Zhang adagula ma seti 15 a S&Makina ozizirira madzi a Teyu CW-5000 kuti aziziziritsa makina awo a 120W CO2 RF. Panthawi ya opaleshoniyo, S&A Teyu water chiller wachita bwino mbali iliyonse. Ndiye nthawi ino, ayikanso oda ina ya ma seti 5 a S&A Teyu CW-5000 madzi ozizira. Posachedwapa, S&Chozizira chamadzi cha Teyu CW-6200 chokhala ndi mphamvu yayikulu yozizirira chingagwiritsidwe ntchito. Tikuthokoza kwambiri Mr. Zhang’kuzindikira ndi kukhulupilira kwa S&A Teyu. Kwa laser ya UV, timalimbikitsanso mtundu woyenera wozizira madzi kwa Mr. Zhang, yemwe akuwonetsa kuti pambuyo pa mgwirizano kwa nthawi yayitali, akudziwa bwino zamtundu wazinthu komanso magwiridwe antchito apamwamba a S.&A Teyu. Kenako, tidzakhala ndi mgwirizano wautali.
