Pa nthawi yokonza mphete za rabara za O-rings zopangidwa ndi kuumba, zinthu za rabara zimadzaza mwachangu dzenje lonse la nkhungu chifukwa zinthu zodzazidwa zimafuna kusokonezedwa pang'ono. Zinthu za rabara zochulukirapo zimayenda motsatira mzere wolekanitsa, zomwe zimapangitsa kuti m'mphepete mwa rabara zikhale zosiyanasiyana m'mimba mwake. Popeza mphete za rabara za O-rings zimafuna kuwongolera bwino komanso mawonekedwe ake chifukwa cha ntchito yawo yotseka, ngakhale m'mphepete mwa rabara zazing'ono zimatha kusokoneza magwiridwe antchito onse otseka. Chifukwa chake, pambuyo pa vulcanization, zinthu zomalizidwa ziyenera kudulidwa m'mphepete kuti zichotse m'mphepete mwa rabara zochulukirapo. Njirayi imatchedwa kudula m'mphepete. Komabe, nthawi zambiri, kukula kwake kukakhala kochepa komanso kukakhala kovuta, kumakhala kovuta kwambiri ndipo nthawi yambiri komanso ntchito yambiri imakhala yovuta.
Pali njira ziwiri zodulira mphira wopangidwa ndi manja ndi makina. Kudulira ndi manja ndi njira yachikhalidwe, pomwe m'mphepete mwa mphira wochulukirapo umadulidwa pang'onopang'ono m'mphepete mwa chinthucho pogwiritsa ntchito zida zamanja. Zimafunika luso lapamwamba kuti muchepetse ndalama zotsala za chinthucho. Kudulira ndi manja kuli ndi ndalama zochepa koma kuli ndi mphamvu zochepa komanso khalidwe lochepa, zomwe zimapangitsa kuti zikhale zoyenera kupanga zinthu zazing'ono. Pali njira ziwiri zodulira ndi makina: kugaya ndi gudumu lopukusira kapena sandpaper, ndi kudula cryogenic kotsika kutentha. Pakadali pano, pali mitundu isanu ya kudula cryogenic: kudula cryogenic kwa vibration, kudula cryogenic kwa swing kapena jiggle, kudula cryogenic kwa rotary drum, kudula cryogenic kwa burashi, ndi kudula cryogenic kwa shot blasting.
Rabala imasinthasintha kuchoka pamlingo wokhuthala kwambiri kupita ku mtundu wagalasi pansi pa kutentha kochepa, zomwe zimapangitsa kuti ikhale yolimba komanso yofooka. Kuchuluka kwa kuuma ndi kusweka kumadalira makulidwe a chinthu cha rabala. Mphete ya O ikayikidwa mu makina odulira cryogenic, m'mbali zoonda za chinthucho zimakhala zolimba komanso zofooka chifukwa cha kuzizira, pomwe chinthucho chimasunga mulingo wina wa kusinthasintha. Pamene ng'oma ikuzungulira, zinthuzo zimagundana wina ndi mnzake komanso ndi zinthu zofooketsa, zomwe zimapangitsa kuti ziwonongeke komanso ziwonongeke zomwe zimaswa ndikuchotsa m'mbali za rabala zomwe zimawonjezera, zomwe zimapangitsa kuti zitheke kudula. Chinthucho chidzabwezeretsanso mawonekedwe ake oyambirira kutentha kwa chipinda.
Kuduladula kwa cryogenic pa kutentha kochepa ndi kothandiza komanso kotsika mtengo. Komabe, kugwira ntchito bwino kwa kuduladula kwamkati mwa m'mphepete ndi kofooka.
Njira ina ndi kupukusa ndi gudumu lopukusa kapena sandpaper.
Mphete ya O-ring yopangidwa ndi vulcanized imayikidwa pa mchenga kapena nayiloni yokhala ndi kukula kofanana kwa m'mimba mwake wamkati, yoyendetsedwa ndi mota kuti izungulire. Pamwamba pakunja pamagwiritsidwa ntchito sandpaper kapena grinder gudumu kuti achotse m'mphepete mwa rabara wochulukirapo kudzera mu kukangana. Njirayi ndi yosavuta komanso yosavuta, yokhala ndi magwiridwe antchito apamwamba kuposa kudula ndi manja, makamaka yoyenera zinthu zazing'ono komanso kupanga magulu akuluakulu. Choyipa chake ndichakuti kudula kwamtunduwu kumadalira kugaya ndi gudumu, zomwe zimapangitsa kuti kulondola kusakhale kolondola komanso kutha bwino kwa pamwamba.
Kampani iliyonse iyenera kusankha njira yoyenera yodulira m'mphepete kutengera momwe zinthu zilili komanso kukula kwa malonda ake. Ndikofunikira kukhala osinthasintha posankha njirayo kuti zinthu ziwonjezeke ndikuchepetsa kutaya, zomwe pamapeto pake zimapangitsa kuti ntchito igwire bwino ntchito.
