1. Ngokuhambelana nezicelo zabathengi, senza izinto zokufudumeza ezenziwe ngezinto ezahlukeneyo (insimbi engenasici, i-PTFE, ithusi, i-titanium, njl.) kunye nezicelo (i-industrial, isixhobo sombane, ukucwiliswa, umoya, njl.).
2. Zininzi izimbo zokugqiba ezahlukeneyo onokukhetha kuzo.
3. I-Magnesium oxide isetyenziselwa kuphela ukucoceka okuphezulu, kwaye ukugquma kwayo kuphucula ukuhanjiswa kobushushu.
4. Zonke izicelo zinokusebenzisa izifudumezi ze-tubular. Ukugqithisela ubushushu obuqhubayo, i-tubular ethe tye inokubekwa kwiigroves ezenziwe ngoomatshini, kwaye imilo ye-tubular ibonelela ngobushushu obungaguqukiyo kulo naluphi na uhlobo lwesicelo esisodwa.
