Zovala zakukhosi zimapangidwa makamaka ndi mphete yapamwamba, mphete yotsika komanso mpira wathunthu. Mapangidwe onse a mphete yokongoletsayo amagwiritsidwa ntchito pozungulira njira zoyendetsera motsika ndi katundu wopepuka. Mapangidwe awiri a mzere umodzi ndi mzere kawiri, komanso kuthekera kwa mabowo okweramo.

M'moyo weniweni wokhumudwitsa, kusiyana kwapakulidwe kozizira kumatha kulamulidwa pa 1%, kuchepa kwa kugwa ndi 0,5mm, ndipo nkhope yomaliza imakhala yochepera 3%.

Kulimbikitsa kumwalira, ndiko kuti, kuti tilepheretse chiphokoso, kusuntha kwabwino, ndikudula mwachidule bar mwakuwala. Zina mwa njirazi zimalimbikitsidwa pokhapokha mpeni wa mpeni umatha, ndipo ena amalimbikitsidwa pamapeto onse a mpeni. Njira zolimbikitsira zimaphatikizapo mtundu wa cylinder ndi makina olumikizira makina.

Zovala zokoka ndi nthumwi yozungulira yomwe ikugwiritsidwa ntchito ndi kugwiritsa ntchito mitundu yambiri. Imagwiritsidwa ntchito ngati liwiro lalitali kapena kuthamanga kwambiri ndipo limakhala cholimba. Zovala zamtunduwu zimakhala ndi mikangano yotsika, malire othamanga, kapangidwe kambiri, mtengo wotsika, komanso kosavuta kukwaniritsa zolondola zapamwamba.

Mphete zopepuka zokhala ndi luso linalake. Ngati itakhala ndi madigiri 10 ophunzitsidwa ndi dzenje, imagwirabe ntchito bwino, koma imakhudzanso moyo wa kubereka. Kulefuliratu mphete zotsekemera nthawi zambiri kumakhala ndi zingwe zitsulo zosungidwa, ndipo zigawo zazikulu zimapangidwa mosavuta kwambiri. Chisindikizo cha mphete zoseketsa ndikulepheretsa mafuta odzanja kuti adutse dzanja limodzi, ndipo mbali inayo kuti mupewe fumbi lakunja, zodetsa ndi chinyezi ndi chinyezi ndi chinyezi komanso chinyezi cholowa mkati mwa zotengera ndikukhudza ntchito wamba.

Popeza zimbalangondo zambiri zimagwira ntchito yolemetsa komanso kuthamanga, mtundu wa kutseka kuzotengera zatengera zotengera ziwiri: Chisindikizo cha Lamuyanthbe. Chisindikizo chabible chonda chokha chimakhala chosavuta. Zagwiritsidwa ntchito kwambiri chifukwa cha ntchito yake yaying'ono yokhala ndi magwiridwe odalirika. Komabe, zotsalazo zake ndikuti milomo yofiyira ya mphira imakonda kukalamba motakatentha kwambiri ndipo imataya magwiridwe ake. Chifukwa chake, mphero zoseketsa zonyamula zomwe zimagwira ntchito pansi pa kutentha kwambiri ndizoyenera kugwiritsa ntchito chidindo cha labyrianth.
