Mumakore achangopfuura, mukugadzirwa kwepurasitiki, nzira yakakurumbira yekugadzira, iri rolling plastic processing. Roll molding, inozivikanwawo seye rotary molding, rotary molding, inzira ye thermoplastic hollow molding. Roll molding yakatanga kuma1940 kuUnited Kingdom, roll molding yakabuda muna 1887, yakagadzirwa muna 1934 muchina wepurasitiki. Pakutanga zvakangofanana nekuumbwa kwejekiseni, kuvhuvhuta, kuwedzera kwekuwedzera, ne polyethylene poda tekinoroji kuti ive mapurasitiki ekuumba maitiro mune inokwikwidza nzira yekuumba.
Mumakore achangopfuura, muNorth America, Europe nyika dzakasimukira, kusimudzira kweindasitiri yepurasitiki inomhanya kwazvo, chiyero chekusimudzira chakakwira kupfuura avhareji yekukura kweindasitiri yese yepurasitiki. Pamusoro pefekitari yefekitari yekuumba muchina uye fekitori yezvigadzirwa zvemapurasitiki, kune huwandu hwakati wandei hwemamwe mafekitori anobatsira, akadai sefekitari yeroller mold, fekitori inoburitsa agent, roller plastic fekitori yakakosha, fekitori yechigayo, yekuisa fekitori uye yakakodzera plastiki roller. kusanganisa fekitori yemidziyo, kune akawanda roller epurasitiki yakakosha mafekitori ekupa zvinhu uye zvichingodaro.
Kazhinji kutaura, United States neEurope, musika weAustralia wakura, asi zvigadzirwa zvitsva uye tekinoroji nyowani yeindasitiri inotenderedza kuunza mikana mitsva yekukura, mitsva yezvigadzirwa zvemhando yepamusoro, kugadzirwa kwekudyara nekukurumidza mumitsara mitsva yekugadzira, kugadzirisa uye kugadzira. kunyika dzinodhura. Munyika dzichiri kusimukira, zvigadzirwa zvakaderera zvakaita sematangi emvura uye matangi ekuchengetera ndizvo zvinogadzirwa zvikuru. Iyo yekumhanyisa yekusimudzira uye giredhi inokanganiswa neiyo yese maindasitiri base. China inokura nekukurumidza, uye nyika dzeAsia dzakadai seIndia, Malaysia, Thailand neVietnam dzinoratidzawo maitiro akanaka ebudiriro. Iko kuvandudza uye kutsvagisa kwekutenderedza kwepurasitiki maitiro muChina kwakatanga mukupera kwema1960s. Mumakore ekuma1990, gare gare, mushure mekunge mamwe mabhizinesi epamba aunza purasitiki yakasimudzwa kubva kunze kwenyika, yakatanga kugadzirwa kwakakura kwemaindasitiri mupfungwa chaiyo. Nekudaro, zvichienzaniswa nedanho repamusoro rekunze kwenyika dzakasimukira, gaka richiri pachena, izvo zvinofanirwa kuratidzwa mune zvinotevera zvinhu: kusagona kudzora kugona kwetsvakiridzo yekutanga, tekinoroji yekudzokera shure, kusakwana kwakasiyana kwezvigadzirwa zvepurasitiki zvakatenderedzwa uye zvichingodaro. Maererano nenhamba, China iripo kupfuura 1500 inokungurutsa zvigadzirwa zvepurasitiki mabhizinesi; Uye mukutanga ma1970s, United States ine mabhizinesi anopfuura mazana mashanu ari kuita kugadzirwa kwezvigadzirwa zvepurasitiki zvinotenderedza, aine anopfuura mazana mashanu seti yemuchina wepurasitiki, United States rolling plastic association yakanyoreswa zvigadzirwa zvepurasitiki zvine marudzi anopfuura 5000. Muchikamu chekukungurutsa epurasitiki zvigadzirwa, parizvino, PE inonyanya kushandiswa mukukungurutsa zvigadzirwa zvepurasitiki muChina. Uye zvinhu zvekunze zvinoshandiswa nekukungurutsa plastiki, naironi, PP, PC, ABS uye zvichingodaro. Nekudaro, mushure meanopfuura makore makumi maviri ebudiriro, iyo China inotenderedza purasitiki maitiro anga akura, akasiyana nemamwe maitiro, ane zvakanakira zviri pachena. Parizvino, ine kugadzirwa kwemazuva ano kwekugadzira zvigadzirwa zvakakura uye zvigadzirwa zvepurasitiki zvakakosha, uye munda wayo wekushandisa uri kuramba uchiwedzera. Indasitiri yepurasitiki inotenderera yakafambira mberi zvikuru. Izvo zvinofanirwa kutaurwa kuti iyo inotenderedza indasitiri yepurasitiki yakagadzira yakazara maindasitiri cheni yezvinhu zvakasvibirira, zvishandiso uye mold.
Roll molding tekinoroji ine simba rakasimba, inokodzera kutariswa kwepamusoro kweiyo maitiro, inofanirwa kutarisisa zvakanyanya kumupumburu wekugadzira, kushingaira kugaya uye kutora tekinoroji yepamusoro, kuwedzera maitiro anoenderana, zvishandiso uye mold tsvagiridzo.
Jinghe rolling plastic Co., Ltd. iri muCixi, China, Cidong Industrial zone, ine makumi emakore eruzivo mukukungurusa mapurasitiki ekugadzira, akashongedzerwa neakanakisa bhizinesi timu uye masevhisi ehunyanzvi, zvigadzirwa zvese zvinogona kugadzirwa zvinoenderana nezvinodiwa nevatengi, kuvhurika kwe mold, kugadzirwa, kana uchida kutibata nesu.
