Ngenxa ye-engeli ye-helix, i-engeli yokusika ye-rake kampompi izokhuphuka njengoba i-engeli ye-helix ikhula.Okuhlangenwe nakho kuyasitshela: Ukuze kucutshungulwe izinsimbi ezisansimbi, i-engeli ye-helix kufanele ibe ncane, ngokuvamile ibe ngamadigri angu-30, ukuze kuqinisekiswe amandla amazinyo e-helical nokusiza ukwelula impilo kampompi.Ukuze kucutshungulwe izinsimbi ezingenayo insimbi njengethusi, i-aluminium, i-magnesium, ne-zinc, i-engeli ye-helix kufanele ibe nkulu, engaba ngama-degree angama-45, futhi ukusika kubukhali, okulungele ukukhishwa kwe-chip.
