Mu makampani otsekera, mphete za polyurethane (PU) O-rings zimagwiritsidwa ntchito kwambiri mu zida za hydraulic, makina odzipangira okha, zida zatsopano zamagetsi ndi zina zofunika, chifukwa cha kukana kwawo misozi, kukana kuvala bwino komanso kusinthasintha kwakukulu. Vuto lakale lamakampani lidakalipo: ngakhale opanga atagwiritsa ntchito zinthu zofanana za polyurethane zopangira mphete za O-rings, zinthu zomwe zamalizidwa zikuwonetsabe kusiyana kwakukulu pakulimba kwa kutsekera, kukana nyengo komanso moyo wautumiki. Kafukufuku waukadaulo wamakampani watsimikizira kuti kapangidwe ka fomula sikulinso chinthu chokhacho chomwe chimasiyanitsa mtundu wa chinthucho. Kuwala kotsalira kuchokera ku njira yopangira ndi cholakwika chobisika chomwe sichingalandiridwe mosavuta. STMC (Nanjing) Precision Machinery yayambitsa zida zotsekera za cryogenic zolondola kwambiri komanso zogwira mtima kwambiri, zomwe zimathetsa bwino ululu wa mphete zotsekera kuchokera ku gwero ndikugwiritsa ntchito mokwanira mphamvu ya zinthu za polyurethane.
Mphete za PU O zimapangidwa makamaka pogwiritsa ntchito compression molding ndi vulcanization. Fine flash ndi burrs zimapangika panja chifukwa cha nkhungu komanso kusefukira kwa zinthu. Opanga ambiri ang'onoang'ono ndi apakatikati amayang'ana kwambiri pa kukonza formula, komabe amadalira njira zosaphika zokonzera zinthu monga kudula ndi manja ndi lumo ndi kupukuta mawilo opukutira kuti achotse zinthu. Njirazi sizimachotsa ma burrs akuluakulu, ndipo nthawi zambiri zimakanda ma O-rings ndi kuyambitsa kusintha kwa mawonekedwe. Flash yooneka ngati yochepa idzasokoneza kulimba kwa ma O-rings ndi ma grooves, zomwe zimapangitsa kuti kutayikira ndi kupanikizika kuchepe pansi pa ntchito yopanikizika kwambiri. Popeza ndi malo ofooka kwambiri omwe ali pansi pa kupsinjika, ma burrs amatha kusweka ndi kung'ambika poyamba panthawi yoyendetsa zida, zomwe zimawononga kwambiri kukana kwa polyurethane misozi. Kuphatikiza apo, ma burrs ali ndi kukana kokalamba kochepa kuposa thupi lalikulu la chinthucho. Amawonongeka mwachangu pamalo otentha kwambiri/otsika komanso owononga, zomwe zimapangitsa kuti mphete yonse yotsekera iwonongeke msanga. Zinyalala zomwe zagwa zidzachotsanso ma circuits amafuta ndi zida zolondola za makina.
Kuyeretsa kwa cryogenic kwa Precision kumadziwika bwino ngati njira yabwino kwambiri yothetsera zolakwika za flash ndikuwonjezera magwiridwe antchito azinthu. Monga kampani yapadziko lonse lapansi komanso kampani ya Jiangsu Province "Yapadera, Yokonzedwanso, Yosiyana komanso Yatsopano" yokhala ndi ukadaulo wazaka zoposa khumi muukadaulo wochotsa ma burrs otsika kutentha, STMC imagwiritsa ntchito luso la Sino-Japanese lolumikizana ndi R&D ndi ukadaulo wambiri wokhala ndi patent kuti ipereke mayankho athunthu oyeretsa cryogenic omwe amaperekedwa ku mphete zotsekera za PU.
Pokhala ndi makina owongolera kutentha olondola kwambiri omwe sasiya kutentha kwambiri, chipangizochi chimangobisa ma edge burrs okha kutentha kochepa pomwe chimasunga kusinthasintha ndi mawonekedwe a thupi la PU O-ring. Chili ndi kapangidwe kawiri ka impeller ka high speed media blasting, chimachotsa flash bwino kuchokera mbali zonse popanda kuwononga kukula kwa chinthucho, mawonekedwe ake kapena kapangidwe ka molekyulu ya chinthucho. Zinthu zomalizidwa zimakhala ndi m'mbali zosalala komanso zoyera komanso kusinthasintha kwabwino kwambiri popanga zinthu zambiri, kukwaniritsa miyezo yolondola kwambiri yochotsera kutentha.
Ponena za kugwira ntchito bwino kwa zipangizo zopangira, zida zoyeretsera za STMC zodzipangira zokha zimachulukitsa ntchito poyerekeza ndi ntchito zamanja. Zimathandiza kukonza mphete za PU O-rings mwachangu, kuchepetsa ndalama zogwirira ntchito komanso kuchepetsa chiwopsezo cha zolakwika pamene zikugwirizanitsa ubwino wapamwamba komanso kugwira ntchito bwino kwa zinthu zambiri. Mphete za PU O-rings zomwe zimagwiritsidwa ntchito ndi zipangizozi zimawona kusintha kwakukulu pakugwira ntchito kotseka, kukana kutentha kwambiri komanso kotsika, komanso kulimba kwa kukalamba. Ndi zipangizo zomwezo, magwiridwe antchito awo onse ndi apamwamba kuposa zinthu zomwe zimakonzedwa ndi njira zachikhalidwe zochotsera mphete.
Opanga zisindikizo zamagalimoto ndi zida zamagetsi anena m'mayeso akumunda kuti atagwiritsa ntchito njira zochotsera zisindikizo za STMC, nthawi yogwiritsira ntchito mphete zotsekera imawonjezeka, ndipo kuchuluka kwa kulephera kwa kutayikira kwa zida kumatsika kwambiri. Zogulitsa zawo zapeza mpikisano wamphamvu m'misika yopereka ma bid komanso yothandiza kwambiri.
Masiku ano, mpikisano wofanana wa zinthu zopangira wakula kwambiri mumakampani otsekera, ndipo kudalira kokha pakusintha kwa formula sikungathenso kupitiriza chitukuko. Mothandizidwa ndi zida zoyeretsera za cryogenic zomwe zimakhala zolondola kwambiri komanso zogwira mtima kwambiri, STMC imathandiza opanga kuchotsa zolakwika zobisika kuchokera ku gwero ndikupereka magwiridwe antchito athunthu a zipangizo za PU O-ring. Njira zopangira zolimba komanso zokonzedwa bwino zimathandizira zinthu zotsekera zapamwamba. Mothandizidwa ndi zida zaukadaulo, opanga otsekera amatha kusiya mpikisano wotsika kwambiri, kupanga zinthu zotsekera zokhazikika komanso zapamwamba, ndikuyendetsa makampani onse otsekera mphira ndi pulasitiki kupita ku kulondola kwambiri, moyo wautali wautumiki komanso automation yonse.
