Isilingi sokuphakamisa i-nylon yomlenze we-4 luyilo olutsha, ngokusebenzisa ubuchwepheshe obugqwesileyo bokucubungula kunye nezinto ezisemgangathweni eziphezulu, ukusebenza kwe- 4 umlenze we-nylon uphakamisa isilingi ukuya kumgangatho ophezulu. Sigqibelele kuzo zonke iinkcukacha zesilingi sokuphakamisa inayiloni emi-4 , siqinisekisa umgangatho womgangatho, ukuze sikuzisele amava emveliso agqibeleleyo. I -Lishenflex yingcali yaseChina i-4 yomlenze we-nylon ephakamisa umenzi we-sling kunye nomthengisi, ukuba ufuna i -4 ye-nylon ehamba phambili yokunyusa isilingi ngexabiso eliphantsi, dibana nathi ngoku!
