Ipulasitiki iyi-polymer yokwenziwa noma yemvelo, uma kuqhathaniswa nensimbi, itshe, izinkuni, imikhiqizo yepulasitiki inezinzuzo zezindleko eziphansi, ipulasitiki, njll.Imikhiqizo yepulasitikiasetshenziswa kabanzi ezimpilweni zethu, imboni yepulasitiki nayo inesikhundla esibaluleke kakhulu emhlabeni namuhla.
Eminyakeni yamuva nje, kuye kwasetshenziswa ubuchwepheshe obusha bokucutshungulwa kwepulasitiki kanye nemishini emisha enanini elikhulu lemikhiqizo yepulasitiki yasendlini, njengokubumba umjovo oqondile, ubuchwepheshe bokubumba obusheshayo, ubuchwepheshe bokubumba umjovo oncibilikayo, umjovo osiza igesi / osiza amanzi. ubuchwepheshe bokubumba, ubuchwepheshe bokubumba umjovo we-electromagnetic ashukumisayo kanye nobuchwepheshe bokubumba umjovo wokumbondela.
Emikhiqizweni yezinto zikagesi zasekhaya, ikakhulukazi izingxenye ezincane zokubumba umjovo wegobolondo likagesi zivame kakhulu ekuphileni kwethu. Okulandelayo yincazelo yokuthi yiziphi izinqubo zokubumba umjovo ezitholakalayo ezingxenyeni ezibunjwe ngomjovo wegobolondo lensimbi encane.
1. Ukubunjwa komjovo ngokunemba
Ukubumba umjovo onembile kudinga izinga eliphezulu lokunemba ukuze kuqinisekiswe ukuthi imikhiqizo inokunemba okuphezulu nokuphindaphinda ngokosayizi nesisindo. Imishini yokubumba i-injection esebenzisa lobu buchwepheshe ingafinyelela ukucindezela okuphezulu kanye nomjovo wejubane eliphezulu.
2. Ubuchwepheshe be-prototyping obusheshayo
Lobu buchwepheshe buthuthuke ngokushesha ngokuhambisana nokuhlukahluka kwemishini yasendlini kanye nokuvuselelwa kwayo njalo, futhi isetshenziselwa ikakhulukazi ukukhiqizwa kwezindlu zepulasitiki zemishini yasendlini. Inzuzo yalobu buchwepheshe ukuthi amaqoqo amancane ezingxenye zepulasitiki angakhiqizwa ngaphandle kwesidingo sokubunjwa.
3. Ubuchwepheshe bokubumba umjovo obalulekile
Le nqubo ivamise ukusetshenziselwa izimbotshana ezimise okudinga ukuhwala nokunemba okuphezulu futhi ayikwazi ukucutshungulwa ngezindlela zokubumba ezingenalutho noma ezijikelezayo. Isimiso salobu buchwepheshe siwukuthi umgogodla kwakheka ukwakha i-cavity bese umnyombo uyabunjwa njengokufakwa.
I-cavity yakhiwa ukushisa kwengxenye ebunjiwe yomjovo, okwenza umnyombo uncibilike futhi uphume. Isici esibaluleke kakhulu sokusebenzisa le nqubo isidingo sokwazi izinto eziwumgogodla kanye nephuzu lokuncibilika lengxenye ebunjiwe. Imvamisa, i-core material ingaba ipulasitiki evamile, i-thermoplastic elastomer noma insimbi encibilikayo ephansi njengomthofu noma ithini, kuye ngesimo.
4. I-Gas Assist Injection Molding
Lokhu kungasetshenziswa ukubumba izinhlobo eziningi zezingxenye ezibunjwe ngomjovo, umkhiqizo ojwayelekile kakhulu yindlu yesethi kamabonakude. Ngesikhathi sokubunjwa komjovo, igesi ijova emgodini cishe kanye kanye ne-plastic melt. Kuleli qophelo, ipulasitiki encibilikisiwe ihlanganisa igesi futhi umkhiqizo wepulasitiki obunjiwe uyisakhiwo sesangweji, esingakhululwa ekubunjweni ngemva kokuba ingxenye ibunjwe. Le mikhiqizo inezinzuzo zokulondoloza izinto ezibonakalayo, ukuncipha okuphansi, ukubukeka okuhle nokuqina okuhle. Ingxenye ebalulekile yemishini yokubumba iyisisetshenziswa esisizwa ngegesi kanye nesoftware yayo yokulawula.
5. Ubuchwepheshe bokubumba umjovo we-Electromagnetic ashukumisayo
Lobu buchwepheshe busebenzisa amandla kazibuthe kagesi ukudala ukudlidliza okuphindaphindayo endaweni ye-axial yesikulufu. Lokhu kuvumela ipulasitiki ukuthi ibe yi-microplastised ngesikhathi sesigaba se-preplasticisation, okuholela ekwakhiweni kwe-denser nokunciphisa ukucindezeleka kwangaphakathi kumkhiqizo ngesikhathi sesigaba sokubamba. Le nqubo ingasetshenziswa ukubumba imikhiqizo efunwa kakhulu, njengamadiski.
6. Ubuchwepheshe bokukhiqiza ifilimu ngokweqile
Kule nqubo, ifilimu yepulasitiki yokuhlobisa ekhethekile ephrintiwe iboshelwa esibunjeni ngaphambi kokubunjwa komjovo. Ifilimu ephrintiwe ikhubazekile ukushisa futhi ingafakwa phezu kwengxenye yepulasitiki, engeyona nje enhle kodwa futhi iqeda isidingo sezinyathelo zokuhlobisa ezilandelayo.
Ngokuvamile, isidingo sesikhunta sepulasitiki semikhiqizo yepulasitiki yezinto zasendlini siphezulu kakhulu, futhi ngesikhathi esifanayo, izidingo zobuchwepheshe zesikhunta sepulasitiki ziphakeme, kanye nomjikelezo wokucubungula kufanele ube mfushane ngangokunokwenzeka, ngaleyo ndlela ukhuthaze kakhulu ukuthuthukiswa. wokuklama isikhunta kanye nobuchwepheshe besimanje bokukhiqiza isikhunta.
