Uphawu :
Sizama ukugqibelela kuzo zonke iinkcukacha.
Izinto zePlastiki zenza ukuba izifakelo zibe khaphukhaphu kwaye zihlangane, i-rivet nut yesinyithi ibona inkonzo ende
ubomi.Umkhono kunye nobukhulu obahlukeneyo bokhetho kulula kakhulu ukudibanisa kunye nokuqhawula.
Ukusebenza kakuhle kokutywinwa kuqinisekisa umgangatho ophezulu.
Phawula :
1. I-NPT, i-PT, intambo ye-G iyakhethwa.
2. Umbala womkhono wombhobho unokwenziwa ngokwezifiso.
3. Uhlobo olukhethekileyo lwee-ftings nalo lunokwenziwa ngokwezifiso.
