M'zaka zaposachedwa, mu ndondomeko ya pulasitiki, njira yotchuka kwambiri yopangira, ndikugudubuza pulasitiki. Kuumba mozungulira, komwe kumadziwikanso kuti kuumba kwa rotary, kuumba kwa rotary, ndi njira yakuumba ya thermoplastic hollow. Kuumba mpukutu kudayamba m'ma 1940 ku United Kingdom, kuumba mpukutu kudatuluka mu 1887, komwe kumapangidwa mu 1934 makina apulasitiki. Poyamba monga jekeseni akamaumba, kuwomba akamaumba, extrusion zowonjezerapo, ndi polyethylene ufa luso kukhala pulasitiki akamaumba ndondomeko mu mpikisano kwambiri akamaumba njira.
M'zaka zaposachedwapa, mu North America, Europe otukuka mayiko, chitukuko cha anagubuduza makampani pulasitiki ndi mofulumira kwambiri, mlingo wake chitukuko ndi apamwamba kuposa mlingo pafupifupi chitukuko cha makampani lonse pulasitiki. Kuwonjezera fakitale wodzigudubuza akamaumba fakitale ndi wodzigudubuza fakitale mankhwala pulasitiki, pali chiwerengero cha mafakitale ena akatswiri wothandiza, monga wodzigudubuza nkhungu fakitale, fakitale wodzigudubuza pulasitiki fakitale wapadera, fakitale mphero, Ikani fakitale ndi oyenera pulasitiki wodzigudubuza. kusakaniza zida fakitale, pali ambiri odzigudubuza pulasitiki wapadera zopangira katundu mafakitale mafakitale ndi zina zotero.
Nthawi zambiri, United States ndi Europe, Australia msika ndi okhwima, koma mankhwala atsopano ndi luso latsopano makampani anagubuduza kubweretsa mipata kukula, zida zatsopano mankhwala khalidwe ndi mkulu, kupanga ndalama mofulumira mizere kupanga zatsopano, processing ndi kupanga. kumayiko otsika mtengo. M’mayiko amene akutukuka kumene, zinthu zotsika mtengo monga matanki amadzi ndi matanki osungiramo zinthu ndizomwe zimagulitsidwa kwambiri. Kuthamanga kwachitukuko ndi kalasi kumakhudzidwa ndi maziko onse a mafakitale. China ikukula mofulumira, ndipo mayiko a ku Asia monga India, Malaysia, Thailand ndi Vietnam akuwonetsanso chikhalidwe chabwino cha chitukuko. Kupanga ndi kufufuza kwa makina apulasitiki ku China kudayamba kumapeto kwa zaka za m'ma 1960. M'zaka za m'ma 1990, pambuyo pake, mabizinesi am'nyumba atayambitsa pulasitiki yapamwamba kuchokera kunja, adayamba kupanga mafakitale akulu kwenikweni. Komabe, poyerekeza ndi mlingo wotsogola wa mayiko otukuka akunja, kusiyana akadali zoonekeratu, zimene ziyenera kuonekera m'mbali zotsatirazi: osauka kulamulira luso la kafukufuku zofunika, m'mbuyo teknoloji, osakwanira zosiyanasiyana adagulung'undisa mankhwala pulasitiki ndi zina zotero. Malinga ndi ziwerengero, China alipo oposa 1500 anagubuduza mankhwala mabizinesi pulasitiki; Ndipo koyambirira kwa zaka za m'ma 1970, United States ili ndi mabizinesi opitilira 500 omwe akupanga zinthu zapulasitiki, zokhala ndi makina opitilira 500 a makina apulasitiki opukutira, bungwe la United States lodzigudubuza la pulasitiki lolembetsedwa lili ndi mitundu yopitilira 5000. Pankhani yakugudubuza zopangira pulasitiki, pakadali pano, PE imagwiritsidwa ntchito kwambiri pakugubuduza pulasitiki ku China. Ndipo zida zakunja zomwe zimagwiritsidwa ntchito ndikugudubuza pulasitiki, nayiloni, PP, PC, ABS ndi zina zotero. Komabe, patapita zaka zoposa 20 chitukuko, China akugubuduza ndondomeko pulasitiki wakhala kwenikweni okhwima, osiyana njira zina, ali ndi ubwino zoonekeratu. Pakalipano, ili ndi zamakono zamakono zopangira zinthu zazikulu ndi mankhwala apadera apulasitiki, ndipo ntchito yake ikukulirakulira nthawi zonse. Makampani opanga mapulasitiki apita patsogolo kwambiri. Tinene kuti anagubuduza makampani pulasitiki wapanga wathunthu mafakitale unyolo wa zipangizo, zipangizo ndi nkhungu.
Pereka akamaumba luso ali ndi mphamvu wamphamvu, ndi woyenera tcheru mkulu wa ndondomeko, ayenera kulabadira kwambiri mpukutu akamaumba ndondomeko, mwachangu digest ndi kuyamwa luso yachilendo patsogolo, kuonjezera ndondomeko zokhudzana, zipangizo ndi nkhungu kafukufuku.
Jinghe rolling plastic Co., Ltd. ili ku Cixi, China, Cidong Industrial zone, yomwe ili ndi zaka zambiri pakugubuduza kupanga pulasitiki, yokhala ndi gulu labwino kwambiri lazamalonda ndi ntchito zaukadaulo, zinthu zonse zitha kusinthidwa malinga ndi zomwe makasitomala amafuna, kutsegula nkhungu, kupanga, ngati mukufuna kulumikizana nafe.
