72 iwindi elinokuvikela.

■ Ukusebenza okuhle khulu kokonga amandla nokuvikela ukutjhisa.
■ Ifreyimu yefasitela yamukela isakhiwo samagumbi amathathu, okwenza ngcono khulu ukuvikela umdumo, ukuvikela ukutjhisa nokusebenza kokuthwala umthwalo.

■ Elula, ehlukileko, esefashinini begodu ephanako.
■ Ubukghwari obuhle khulu, ubujamo obuhle nobuhle, ukusebenza okuphezulu kokulwisana nokugqwala, indawo ephathwe nge-anodizing nofana ithekhnoloji yokufafaza, umuzwa wezandla obutjhelelako nobuthakathaka.

■ Idili elibonakalako, eliphephileko nelijamelana nokugandeleleka.
■ Umklamo omncani wokugoqa isikwere, wenza ngcono ukusebenza kokujamelana nomoya kwefreyimu yefasidera, okwenza iminyango namafasidera aphephe, lokha nakuzuzwa umphumela omncani.

■ Ukugeleza okubushelelezi nokubukeka okuhle.
■ Umklamo wesakhiwo sokukhipha amanzi esifihlekileko wamukelwa, begodu umthetho wokuzithwala kwamanzi usetjenziselwa ukwenza ukugeleza kube bushelelezi begodu kuvimbele amanzi wezulu bona angabuyeli emuva. Amanzi wezulu angakhutjhwa msinyana ngaphandle kwegumbi ngaphandle kokwesaba isiwuruwuru.

■ Ukuvikela umoya obandako nokutjhisa, gcina amazinga womtjhiso.
■ Nge-PA66 umtjhini wokuvikela kanye nomklamo wama-isotherms ajame ngqo, ovimbe kuhle ukudluliswa komoya obandako nokutjhisa.
