Dongguan Enuo mold Co., Ltd idivi reHong Kong BHD Boka, bhizinesi repakati nderekugadzira jekiseni mold uye kuumba jekiseni. Uyezve, Enuo mold iri zvakare fekitori yeOEM inobatikana mukuongorora fixture/Gauge R&D, Die casting, CNC machining, Prototype zvigadzirwa R&D, Zvikamu zvekupfapfaidza uye kusangana.
Jekiseni kuumbainoshandisa gondohwe kana screw-type plunger kumanikidzira zvinhu zvepurasitiki zvakanyungudutswa kupinda mugomba; uku kusimba kuita chiumbwa chinopindirana nechiumbwa . Inonyanya kushandiswa kugadzira ese ari maviri thermoplastic uye thermosetting mapolymer, nehuwandu hunoshandiswa hwekare huchikwira zvakanyanya. Thermoplastics asi yakawanda nekuda kwehunhu hunovaita kuti vanyatsokodzera kuumbwa kwejekiseni, sekureruka kwekudzokorora, kuita zvakasiyana-siyana kune akasiyana siyana ekushandisa, uye kugona kupfava nekuyerera pakudziya.
Thermoplastics inewo chinhu chekuchengetedza pamusoro pe thermosets; kana thermosetting polymer isina kubudiswa kubva mugomba rejekiseni nenguva, kemikari crosslinking inogona kuitika ichikonzera sikuru uye cheki mavharuvhu kuti abate uye zvingangokuvadza jekiseni rekuumba muchina.
isu tiri mumwe wemapiyona mumunda wePlastiki jekiseni molding muGermany.
Chiiplastiki, chinhu ichi chasvika zvakadzika muhupenyu hwedu? Shoko racho rinobva pashoko rechiito rechiGiriki rokuti plassein, rinoreva "kuumba kana kuumba." Mapurasitiki ane hunyanzvi hwekuumbwa nekuda kwechimiro chawo, iwo akareba, anochinjika cheni dzeatomu kana mamorekuru madiki akasungirirwa patani inodzokororwa kuita imwe inobwinya molecule. "Wakamboona polypropylene molecule?" aifarira maplastic akambondibvunza. "Ndicho chimwe chezvinhu zvakanakisa zvawati wamboona. Zvakafanana nekutarisa cathedral inoramba ichienderera mberi kwemakiromita."
Michina yekuumba jekiseni-ikozvino midziyo yakajairwa mukugadzira mapurasitiki-yakashandura hupfu hwepurasitiki kana mapellets kuita chigadzirwa chakaumbwa, chakapedzwa mukupfura kamwe chete. Muchina mumwe chete wakashongedzerwa ne mold ine makomba akawanda unogona kubuda mizinga gumi yakaumbwa zvizere mukati meminiti isingasviki.
Mazhinji eiyo thermoplastics mitsva pane imwe nguva akawana nzira yawo mumizinga, iyo, nekuda kwekugadzira jekiseni uye humwe hunyanzvi hwekugadzira tekinoroji, yaigona kugadzirwa nekukurumidza uye muhuwandu hukuru kupfuura nakare kose- zviuru zvemizinga muzuva rimwe chete. Ichi chaive chiitiko chidiki mukati uye chega, asi chakapetwa pane zvese zvinodiwa uye zveumbozha izvo zvinozogona kugadzirwa zvisingadhure zvakawanda, zvinonzwisisika kuti nei vazhinji panguva iyoyo vaiona mapurasitiki sechiratidzo chenguva itsva yekuwanda. Mapurasitiki, asingadhuri uye aigadzirwa zviri nyore, aigovera ruponeso kubva mukugovewa kusina kujeka uye kusina kuenzana kwezviwanikwa izvo zvakanga zvapfumisa dzimwe nyika, zvakasiya dzimwe dzichiva varombo, uye zvakakonzera hondo dzinoparadza dzisingaverengeki. Plastiki yakavimbisa utopia yezvinhu, inowanikwa kune vese.
