Kuphatikiza apo, ma pinholes ndi kuwonongeka kwanuko m'chimake cha pulasitiki kungapangitse chinyezi kulowa pachimake cha chingwe, mawonekedwe amagetsi a chingwe amawonongeka. Anapezanso kuti kuwonongeka kwa jekete la chingwe si malo omwe zizindikiro zotumizira zimawonongeka, zomwe zimapereka chisamaliro cha chingwe ndi kuthetsa mavuto ambiri, kotero popanga chingwe, nthawi zambiri njira zitatu zowonetsetsa kuti chinyezi ndi madzi. chingwe chomwe chimakwiriridwa kapena kudzazidwa ndi mafuta odzola pogwiritsa ntchito zinthu zotsekemera kwambiri, zomwe zimakhala ndi mafuta odzola kunyumba ndi zochulukirapo. Zingwe zodzaza mafuta odzola odzola, CHIKWANGWANI chamawonedwe chingwe chonse kusiyana, pakati pa madzi chisindikizo amasewera mbali ya CHIKWANGWANI kuwala kuchokera kunja chilengedwe, kukulitsa moyo wake, ndipo palibe kukonza angathe kukhalabe kukhazikika kwa nthawi yaitali ndi kudalirika kwa kufala kwa fiber optic.
