Kukula kwa ntchito
- Malo osangalalira ndi nyumba zokhalamo, malo opezeka anthu ambiri, nyumba zochitira zisudzo ndi nyumba zamalonda;
- Mafakitale a makina, mafakitale a mankhwala, magaraji, malo osungiramo katundu, malo ogulitsira katundu, mafakitale osindikizira;
- Malo ochitira zisudzo, zipinda zamainjini, ndi makina oyendetsera pansi m'malo apadera.
Makhalidwe a magwiridwe antchito
- Mawonekedwe okongola komanso athyathyathya, mpaka pagalasi:
- Mphamvu yayikulu, kuuma kwakukulu, kukana kwamphamvu kwa kukwawa;
- Kumamatira mwamphamvu, kusinthasintha kwabwino komanso kukana kugwedezeka;
- Kulimbana ndi dzimbiri la madzi, mafuta, asidi, alkali ndi mankhwala ena onse;
- Palibe mipata, yosavuta kuyeretsa, yosavuta kusamalira.
Makhalidwe a dongosolo
- Yopangidwa ndi zosungunulira, mtundu wolimba, yonyezimira;
- Kunenepa 2-5mm;
- Moyo wonse wautumiki ndi zaka zoposa 10.

Njira yomanga
- Kukonza nthaka yopanda kanthu: kuyeretsa, pansi pake pamafunika ng'oma youma, yathyathyathya, yopanda dzenje, kapena kuyeretsa kwambiri;
- Choyambira: chophatikiza kawiri malinga ndi kuchuluka kwa zomwe zanenedwa poyambitsa (kuzungulira kwamagetsi kwa mphindi 2-3), ndi chopangira chozungulira kapena chokokera;
- Mu matope a utoto: magawo awiri ofanana malinga ndi kuchuluka kwa mchenga wa quartz womwe wasunthidwa (kuzungulira kwamagetsi kwa mphindi 2-3), ndi chopangira chokokera;
- Mu utoto wa putty: magawo awiri olingana malinga ndi kuchuluka komwe kwatchulidwa kosakaniza (kuzungulira kwamagetsi kwa mphindi 2-3), ndi kapangidwe ka scraper;
- Chophimba pamwamba: chopaka utoto chodziyimira payokha ndi chopopera malinga ndi kuchuluka kwa kusakaniza komwe kwatchulidwa (kuzungulira kwamagetsi kwa mphindi 2-3), pogwiritsa ntchito tsamba lopopera kapena lokwela lopangidwa ndi mano.
