I-Dongguan Enuo mold Co., Ltd iyinkampani engaphansi kwe-Hong Kong BHD Group, ibhizinisi eliyinhloko ukukhiqizwa kwesikhunta somjovo kanye nokubumba umjovo. Ngaphezu kwalokho, isikhunta se-Enuo siyifektri ye-OEM ebandakanyeka ekuhlolweni kwemishini/ukuhlolwa kwe-Gauge, ukuphonswa kwe-die, ukushintshwa kwe-CNC, ukuhlaziywa kwemikhiqizo ye-Prototype kanye nokuthuthukiswa, ukufuthwa kwezingxenye kanye nokuhlanganiswa.
Ukubumba ngomjovoKuqukethe ukufakwa kwengcindezi ephezulu kwezinto zokusetshenziswa ku-mold, okwakha i-polymer ibe yisimo esifunwayo. Izikhunta zingaba yi-cavity eyodwa noma i-cavity eziningi. Ezikhunta eziningi, i-cavity ngayinye ingafana futhi yakhe izingxenye ezifanayo noma ingaba ehlukile futhi yakhe ama-geometri amaningi ahlukene ngesikhathi somjikelezo owodwa. Izikhunta ngokuvamile zenziwa ngezinsimbi zamathuluzi, kodwa izinsimbi ezingagqwali kanye nezikhunta ze-aluminium zifanelekela izinhlelo ezithile.
Izikhunta ze-aluminium ngokuvamile azifaneleki ukukhiqizwa komthamo omkhulu noma izingxenye ezinezinga elincane lokubekezelelana, njengoba zinezakhiwo eziphansi zemishini futhi zivame ukuguguleka, ukulimala, kanye nokuguquka ngesikhathi sokujikeleza kokujova kanye nokubopha; noma kunjalo, izikhunta ze-aluminium zisebenza kahle ekusetshenzisweni komthamo ophansi, njengobaizindleko zokukhiqiza isikhuntafuthi isikhathi sincishisiwe kakhulu. Izikhunta eziningi zensimbi zenzelwe ukucubungula izingxenye ezingaphezu kwesigidi ngesikhathi sokuphila kwazo futhi zingabiza amakhulu ezinkulungwane zamaRandi ukuzenza.
Imishini yokubumba ngomjovoaqukethe i-hopper yezinto ezibonakalayo, i-injection ram noma i-screw-type plunger, kanye ne-heating unit. Eyaziwa nangokuthi ama-platens, abamba izikhunta lapho izingxenye zakhelwe khona. Izingcindezi zilinganiswa nge-tonnage, eveza inani lamandla okubopha umshini ongawasebenzisa. La mandla agcina isikhunta sivaliwe ngesikhathi senqubo yokujova.
Ingcweti Kwezopulasitiki Nokubumba Nge-Plastic Injection e-USA
Kuyiniipulasitiki, le nto esifinyelele ngokujulile kangaka ezimpilweni zethu? Leli gama livela esenzweni sesiGreki esithi plassein, okusho ukuthi "ukubumba noma ukubumba." Amapulasitiki analo ikhono lokubumba ngenxa yesakhiwo sawo, lawo maketanga amade, aguquguqukayo ama-athomu noma ama-molecule amancane ahlanganiswe ngendlela ephindaphindayo abe yi-molecule eyodwa enkulu kakhulu. "Wake wayibona i-molecule ye-polypropylene?" umthandi wepulasitiki wake wangibuza. "Kungenye yezinto ezinhle kakhulu owake wazibona. Kufana nokubuka isonto elikhulu eliqhubeka amamayela amaningi."
Imishini yokubumba ngomjovo—manje eyimishini ejwayelekile ekukhiqizeni ipulasitiki—yaguqula izimpushana zepulasitiki noma ama-pellets aluhlaza aba umkhiqizo obunjiwe, oqediwe ngenqubo eyodwa. Umshini owodwa ohlonyiswe ngesikhunta esinezimbobo eziningi wawungakhipha amakamu ayishumi akhiwe ngokugcwele ngaphansi komzuzu.
Ama-thermoplastic amaningi amasha ngesikhathi esithile athola indlela yawo yokungena kuma-combs, okwathi, ngenxa yokubumba nge-injection kanye nobunye ubuchwepheshe obusha bokukhiqiza, angenziwa ngokushesha nangobuningi obukhulu kunanini ngaphambili—izinkulungwane zama-combs ngosuku olulodwa. Lokhu kwakuyinto encane ngokwayo, kodwa yanda kuzo zonke izidingo kanye nezinto zokunethezeka ezazingakhiqizwa ngobuningi ngentengo ephansi, kuyaqondakala ukuthi kungani abaningi ngaleso sikhathi babebona amapulasitiki njengophawu lwenkathi entsha yenala. Amapulasitiki, akhiqizwa ngentengo ephansi futhi kalula, anikeza insindiso ekusakazweni okungahleliwe nokungalingani kwemithombo yemvelo okwakwenze ezinye izizwe zaceba, kwashiya ezinye zimpofu, futhi kwabangela izimpi eziningi ezibhubhisayo. Amapulasitiki athembisa i-utopia yezinto ezibonakalayo, etholakala kubo bonke.
