Tsamba lozizira lozizira ndi pepala lopangidwa ndi kugudubuza koyilo yotentha ngati chinthu ndikugudubuza pansi pa kutentha kwa recrystallization kutentha.
Pa nthawi yonse yopangira mapepala ozizira, chifukwa palibe kutentha komwe kumachitidwa, palibe zolakwika monga maenje ndi mamba omwe nthawi zambiri amakhalapo pamoto wotentha, ndipo mawonekedwe ake ndi abwino ndipo mapeto ake ndi apamwamba. Ndipo zinthu zozizira zoziziritsa kukhosi zimakhala zolondola kwambiri, ndipo magwiridwe antchito ndi makonzedwe azinthu zimatha kukwaniritsa zofunikira zina zapadera, monga ma elekitiroma ndi ntchito zojambulira zakuya.
Chipepala chozizira chozizira chimakhala ndi ntchito yabwino kwambiri, ndiko kuti, zingwe zozizira zozizira ndi mapepala achitsulo okhala ndi makulidwe ochepa kwambiri komanso olondola kwambiri amatha kupezeka pambuyo pa kugudubuza kozizira, ndi flatness mkulu, pamwamba pamwamba mapeto, woyera ndi yowala maonekedwe ozizira adagulung'undisa pepala. , komanso yosavuta kugwiritsa ntchito.
Pali mitundu yambiri ya plating, ndipo imagwiritsidwa ntchito kwambiri. Pamodzi ali ndi mawonekedwe apamwamba a stamping, palibe ukalamba, komanso zokolola zochepa. Choncho, mbale zozizira zozizira zimagwiritsidwa ntchito kwambiri. Amagwiritsidwa ntchito makamaka pamagalimoto, ng'oma zachitsulo zosindikizidwa, zomangamanga, zomangira, njinga ndi ntchito zina. Pamodzi, akadali chisankho chabwino kwambiri chopangira mapepala achitsulo opangidwa ndi organic.
