Mapangidwe a bokosi a botolo la botolo akhoza kuwonjezera mtundu uliwonse wa mtundu, ndipo mapangidwe a arc a mapewa amawonjezera chiyanjano ndi chitonthozo, chomwe chiri chophweka koma chosavuta.
Mapangidwe apamwamba kwambiri a botolo lamafuta onunkhirawa ndi kapu ya botolo, yomwe imasiya pulasitiki yachikhalidwe kapena chitsulo ndi kapangidwe ka cylindrical, ndikuyika m'malo mwake ndi chipewa chansungwi chosawoneka bwino, chomwe chimayikidwa pamwamba pamaziko a mawonekedwe a cylindrical wamba.Mapangidwe a chipewa chozungulira ali ngati makutu awiri, okongola komanso osewerera, omwe amaphatikizapo kufunafuna kwa amayi amakono a mafashoni, moyo waufulu ndi wotentha mtima.
Makampani a nsungwi ndi bizinesi yobiriwira yomwe imadziwika padziko lonse lapansi yokhala ndi chikhalidwe, zachuma, zachilengedwe komanso chikhalidwe.Kukula kwake kwadutsa magawo otsatirawa: 1. Zaka za m'ma 1970 zisanafike, zinthu za nsungwi zinali zofunika kwambiri tsiku ndi tsiku, makamaka popanga zolemba zosavuta komanso zopangidwa wamba;kuyambira kumayambiriro kwa zaka za m'ma 1980 mpaka kumayambiriro kwa zaka za m'ma 1990, makamaka chifukwa cha kukhazikitsidwa kwa teknoloji, kuyamwa ndi kusinthika, ndi kupititsa patsogolo luso la makina opangira makina, kuchuluka kwa zinthu zogulitsa mafakitale kunawonekera;3. Kuyambira kumapeto kwa zaka za m'ma 1990 mpaka kumayambiriro kwa zaka za m'ma 2100, matekinoloje atsopano osiyanasiyana monga Bamboo akukula mofulumira, zatsopano zikutuluka nthawi zonse, ndipo kukula kwa mafakitale kwakula kwambiri;4. Kuyambira 2015 mpaka 2025, malonda a nsungwi akukumana ndi kusintha kwapangidwe pansi pa kamangidwe katsopano, kuchotsa matekinoloje obwerera m'mbuyo, ndi gawo lofunikira la kusintha ndi kukweza.Gawoli likhala logwirizana ndi mafakitale ansungwi.Ndi nthawi yofunika kwambiri pachitukuko chokhazikika komanso chathanzi komanso kusintha mwachangu.Masiku ano, kutengera kufunikira kwamakampani ansungwi pachitukuko chachuma komanso chitetezo chachilengedwe, chitukuko chamakampani ansungwi chili ndi zofunikira komanso zofunikira m'dziko langa komanso m'maiko onse opanga nsungwi padziko lapansi.Ndi bizinesi yampikisano yobiriwira yakutuluka kwadzuwa pamsika wapadziko lonse lapansi.Timagwiranso ntchito mwakhama ku gulu lankhondo la makampani obiriwira a dzuwa ndi kufunafuna chitukuko china chachuma pamaziko a chitetezo cha chilengedwe chobiriwira.
