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 ngomjovoisebenzisa i-ram noma i-plunger yohlobo lwe-screw ukuphoqa izinto zepulasitiki ezincibilikisiwe ukuba zingene emgodini wesikhunta; lokhu kuqina kube yisimo esivumelana nokwakheka kwesikhunta. Isetshenziswa kakhulu ukucubungula ama-polymer e-thermoplastic kanye ne-thermosetting, kanti ivolumu esetshenziswayo yeyokuqala iphakeme kakhulu. Ama-thermoplastic kodwa avame kakhulu ngenxa yezici ezenza afaneleke kakhulu ekubunjweni komjovo, njengokulula kokusebenzisa kabusha, ukuguquguquka kwezicelo ezahlukahlukene, kanye nekhono lokuthambisa nokugeleza lapho kushisa.
Ama-thermoplastic nawo anesici sokuphepha ngaphezu kwama-thermoset; uma i-polymer ye-thermosetting ingakhishwa emgqonyeni wokujova ngesikhathi esifanele, ukuxhumanisa kwamakhemikhali kungase kwenzeke okubangela ukuthi isikulufu nama-valve okuhlola abambe futhi okungenzeka kulimaze umshini wokubumba wokujova.
Singabanye babasunguli emkhakheni wokubumba nge-plastic injection eJalimane.
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.
