Iyini i-Extrusion Molding?
I-Extrusion molding, eyaziwa nangokuthi i-extrusion ekucutshungulweni kwepulasitiki, isebenzisa ingcindezi ye-hydraulic ukuze iphoqelele izinto ngokusebenzisa isikhunta, idale izingxenye eziqhubekayo zomumo ohlukahlukene. Le nqubo ihlanganisa ukushisisa okokusebenza njengoba kuphushelwa phambili ngesikulufu emgqonyeni, okuholela ekwakhekeni kwamaphrofayili aqhubekayo noma imikhiqizo emaphakathi. Ukubumba i-Extrusion, ubuchwepheshe bakuqala ekucutshungulweni kwe-polymer, buye kwavela eminyakeni eyi-100 edlule yaba indlela esebenza kahle kakhulu, eqhubekayo, enezindleko eziphansi futhi esebenza kabanzi. Manje isiyindlela yokwenza esetshenziswa kakhulu embonini yokucubungula i-polymer ngenxa yokuguquguquka kwayo, amanani aphezulu okukhiqiza, kanye nokuhlukahluka.
Izinqubo Eziyisisekelo ku-Extrusion Molding
1. Ukondla
Impahla yepulasitiki ifakwa ku-hopper futhi idlulele kumashaneli ayisikulufu ngaphansi kwamandla adonsela phansi noma ngosizo lwesiphakeli, iqhubekela ngasekhanda lokufa.
2. Ukudlulisa
Njengoba ipulasitiki ingena esiteshini sesikulufu, iya phambili ngokuzungezisa isikulufu ngakunye. Izinga langempela lokuthutha lincike kuma-coefficients okungqubuzana epulasitiki ngokumelene nombhobho nesikulufu. Ukungqubuzana okuphezulu komgqomo noma ukungqubuzana okuphansi ngesikulufu kukhulisa ukuya phambili kwepulasitiki.
3. Ukucindezelwa
Ukucindezela kubalulekile ekubumbeni i-extrusion. Ipulasitiki iwumqhubi ompofu wokushisa, futhi noma yiziphi izikhala phakathi kwezinhlayiya zingavimbela ukudluliswa kokushisa, kuthinte izinga lokuncibilika. Ukucindezela kusiza ukuxosha amagesi ezintweni, kuvimbele amaphutha, futhi kuqinisekise ukuminyana komkhiqizo ngokugcina umfutho wesistimu ephezulu.
4. Ukuncibilika
Ngokukhuphuka kwengcindezi, othintana naye wepulasitiki oqinile onyakazayo futhi uhlikihla odongeni lombhobho oshisayo, kwakheka ifilimu elincibilikayo elincanyana. Le filimu isulwa isikulufu njengoba ihamba, inqwabelana phambi kwezindiza eziyisikulufu bese kwakheka ichibi lokuncibilika.
5. Ukuxuba
Ngaphansi kwengcindezi ephezulu, izinto eziqinile zihlanganiswa zibe ipulaki eliminyene. Ukuxuba kwenzeka kuphela phakathi kwezingqimba zezinto ezincibilikisiwe, hhayi ngaphakathi kwepulaki eliqinile.
6. Ukukhathala
Ukungena komoya kubalulekile ukuze kukhishwe amagesi nomhwamuko okhiqizwa ngesikhathi senqubo yokukhipha umoya. Ukungenisa umoya ngendlela efanele kuqinisekisa ikhwalithi yomkhiqizo wokugcina ngokuvikela i-voids kanye nokukhubazeka.
Izinzuzo Extrusion Molding
Izisetshenziswa Ezilula Ngokutshalwa Kwezimali Okuphansi: Imishini yokubumba i-extrusion iqondile futhi iyonga imali.
Ukukhiqiza Okuqhubekayo Ngokusebenza Kahle Kakhulu: I-Extrusion ivumela ukukhiqizwa okuqhubekayo, okukhuphula ukusebenza kahle.
Iziqu Eziphakeme Zokuzenzakalela: Ukuzenzakalela kunciphisa umfutho wabasebenzi futhi kwenyuse ukunemba.
Ukusebenza Okulula Nokulawula Inqubo: Inqubo isebenziseka kalula futhi iyalawuleka.
Imikhiqizo Engafani Nekhwalithi Ephezulu: Inqubo ye-extrusion ikhiqiza imikhiqizo engashintshi futhi eminyene.
Ukuhambisana Kwezinto Ezibanzi: Ama-thermoplastics amaningi nezinye izinto zokubeka i-thermosetting zingasetshenziswa.
Izicelo Ezihlukahlukene: Ukubunjwa kwe-Extrusion kulungele imikhiqizo ehlukahlukene, okwenza kube inqubo esebenzayo.
Imigqa Yokukhiqiza Ehlangene: Inqubo idinga indawo encane futhi igcina indawo yokukhiqiza ehlanzekile.
Okucatshangelwayo Okubalulekile Ekubumbeni I-Extrusion
Ukuhlola Ngaphambi Kokuqalisa: Hlola umgqomo, i-hopper, nezixhumi, uqinisekise ukuthi zonke izingxenye zivikelekile. Gcoba njengoba kudingeka futhi uhlanze okokusebenza.
Ukuqala Kwesivinini Esiphansi: Ekuqaleni sebenzisa isikulufu ngesivinini esiphansi, ukuqapha noma yikuphi ukungahambi kahle ekusebenzeni kwemoto noma umsindo.
Isivivinyo Esifushane Sokungalayishi: Isilingo sokukhawulela isikulufu sisebenza emizuzwini engama-30 ngaphambi kokunamathisela isikhunta sokukhiqiza, sigcoba amabhawodi esikhunta ukuze asuswe kalula.
Ukondla Kancane Kancane: Qala ngesivinini esiphansi sesikulufu kanye nezinto eziphakelayo ngokulinganayo, ubheke noma yikuphi ukushintshashintsha kwamandla enjini.
Ukuqapha Izinga lokushisa: Hlola ngokuqhubekayo amazinga okushisa okuthwala, uqinisekisa ukuthi akukho ukuthintana okuqondile nezingxenye ezihambayo ngesikhathi sokusebenza.
Izixazululo Zokushusha Kwaphezulu: Khulisa izinga lokushisa, lungisa isivinini sesikulufu, buyisela izihlungi, futhi usebenzise izinto ezomisa ezifanelekile ukuze uvimbele ukonakala kwendawo.
Ukuvimbela Ukukala: Yehlisa ukusetshenziswa kwe-lubricant, thuthukisa izinto ezibonakalayo, noma sebenzisa okokunamathela kwe-Teflon ukuze unciphise ukukala.
Ukugcina Okukhiphayo Okuzinzile: Bhekana nokuguquguquka ngokulungisa izimo, usebenzisa umumo ohlukile wesikulufu, nokulawula ukuhluka kwezinga lokushisa ukuze uqinisekise ukukhishwa okungaguquki.
Izicelo ze-Extrusion Molding
Amaphrofayili e-plastic extrusion alungele ukukhiqiza amapayipi, amaphrofayili eminyango, izingxenye zezimoto, nokuningi.
1. Amapayipi namashubhu
I-Extrusion ivame ukusetshenziselwa ukukhiqiza amapayipi epulasitiki kanye namashubhu kusuka ezintweni ezifana ne-PVC namanye ama-thermoplastics.
2. I-Wire Insulation
Ama-thermoplastics amaningi angama-insulators amahle kakhulu, awenza afanelekele ukufakwa kwezintambo eziphumayo kanye nekhebula kanye ne-sheathing, kufaka phakathi izinketho ze-fluoropolymer.
3. Amaphrofayili eminyango nefasitela
I-PVC iyinto ethandwayo yokukhipha amafreyimu eminyango namafasitela aqhubekayo, alungele izinhlelo zokusebenza zasendlini.
4. Izimpumputhe
I-Thermoplastics ingakhishwa ukuze yenze ama-slats afanayo wezimpumputhe, ngokuvamile kusetshenziswa i-polystyrene ukubukeka kokhuni okungamanga.
5. Weather Stripping
Imikhiqizo yokuhlubula isimo sezulu senjoloba ivamise ukukhishwa, inikeze izixazululo ezisebenzayo zokuvala izinhlelo zokusebenza ezahlukahlukene.
6. Windshield Wiper kanye Squeegees
Amawipha omoya wezimoto kanye nama-squeegee blades enziwa ngesandla ngezinto zenjoloba zokwenziwa ezifana ne-EPDM.
Ukuguquguquka nokusebenza kahle kokubunjwa kwe-extrusion kuyenza isisekelo embonini yokukhiqiza ipulasitiki, enohlu olubanzi lwezinhlelo zokusebenza nezinzuzo eziqhuba ukusetshenziswa kwayo okusabalele.
