M'manja laser kuwotcherera makina ali ndi ubwino zotsatirazi:
1.Handheld laser kuwotcherera makina akhoza kuchita mtunda wautali ntchito laser kuwotcherera ndipo ndi kusinthasintha kuposa lokhazikika laser kuwotcherera makina;2.The kuwotcherera mutu wa m'manja laser kuwotcherera makina n'zosavuta ntchito ndipo akhoza kuchita ntchito kuwotcherera pa ngodya zosiyanasiyana m'malo osiyanasiyana;
3.Imagwiritsa ntchito kuwala kwa infuraredi kuti ipeze, yomwe ili yolondola kwambiri kuposa makina owotcherera achikhalidwe;
Pakuziziritsa makina owotcherera m'manja a laser, tikulimbikitsidwa kugwiritsa ntchito S&A Teyu mafakitale otenthetsera madzi.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.
