Gasket yakuda yamphamvu kwambiri ndi gasket yomwe imapanga filimu yakuda ya Fe₃O₄ oxide pamwamba pa chitsulo cha alloy kudzera mu okosijeni wamankhwala (mankhwala akuda), okhala ndi makulidwe a filimu pafupifupi 0.5-1.5μm. Zinthu zake zoyambira zimakhala 65 manganese chitsulo kapena 42CrMo aloyi chitsulo, ndipo pambuyo kuzimitsa + kutentha mankhwala, kuuma akhoza kufika HRC35-45.

Ma gaskets amtundu wa zinki amasinthidwa pamaziko a electrogalvanizing kuti apange filimu yamtundu wa utawaleza (yokhala ndi trivalent chromium kapena hexavalent chromium) yokhala ndi makulidwe a filimu pafupifupi 0.5-1μm. Kuchita kwake kotsutsana ndi dzimbiri ndikwabwinoko kuposa electrogalvanizing wamba, ndipo mtundu wapamtunda ndi wowala, ndi magwiridwe antchito komanso kukongoletsa.

Ma gaskets opangidwa ndi malata ndi ma gaskets omwe amayika nthaka yosanjikiza pamwamba pa chitsulo cha kaboni kapena chitsulo cha aloyi kudzera munjira ya electrolytic. The makulidwe a nthaka wosanjikiza zambiri 5-15μm. Pamwamba pake ndi woyera wasiliva kapena bluish woyera, ndipo imakhala ndi ntchito zotsutsana ndi dzimbiri komanso zokongoletsera. Ndi imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri pazamankhwala pamakampani.

Nangula wa ambulera amatchulidwa chifukwa mapeto a bolt ndi mbedza yooneka ngati J (yofanana ndi chogwirira cha ambulera). Amakhala ndi ndodo ya ulusi ndi mbedza yooneka ngati J. The mbedza gawo kwathunthu ophatikizidwa mu konkire kupereka kukoka-kunja kukana.

Nangula ya mbale yowotcherera imakhala ndi ndodo ya ulusi, nthiti yolimba komanso nthiti yolimba. Padiyo imayikidwa ndi ma bolts powotcherera kuti apange chophatikizika cha "bolt + pad". Pad imawonjezera malo okhudzana ndi konkire, imabalalitsa katunduyo ndikuwongolera bata.

Nangula wa mawonekedwe 7 amatchulidwa chifukwa mbali imodzi ya bolt imapindika mu mawonekedwe a "7". Ndi imodzi mwa mitundu yofunikira kwambiri ya mabawuti a nangula. Kapangidwe kake kamakhala ndi ndodo ya ulusi ndi mbedza yooneka ngati L. Gawo la mbedza limakwiriridwa mu maziko a konkire ndikulumikizidwa ku zida kapena kapangidwe kachitsulo kudzera mu mtedza kuti akwaniritse kukhazikika kokhazikika.
