Insimbi yensimbi eyisiyingi enqamula uhhafu oyindilinga, isikulufu sokucofa intambo ephezulu ephansi iyisibophelelo esivamile esisetshenziswa kakhulu emikhakheni efana nezakhiwo, ifenisha, nezimoto. Yenziwe ngensimbi yekhwalithi ephezulu, enendawo ephathwa nge-zinc plating, enokumelana nokugqwala okuhle kanye nobuhle.
Isici salo mkhiqizo yisakhiwo samazinyo esiphezulu nesiphansi, esingaxhuma ngokushesha izingxenye ezimbili ndawonye futhi akulula ukukhulula ngesikhathi sokusetshenziswa. Ngaphezu kwalokho, idizayini yayo yekhanda eliyindilinga eliyindilinga yesiphambano nayo yandisa ukusebenza kobuhle nokuphepha komkhiqizo.
