Vuthela Ukubumba: I-Blow Molding bubuchule obukhawulezayo, obunobuchule bokudibanisa izibambi ezingenanto zeepholima ze-thermoplastic. Izinto ezenziwe kusetyenziswa lo mjikelo ubukhulu becala zineendonga ezibhityileyo kwaye zifikelela kubukhulu kunye nokumila ukusuka kwijagi encinci, eyoyikekayo ukuya kwiitanki zegesi ezizenzekelayo. Kulo mjikelo imilo ye-cylindrical (i-parison) eyenziwe nge-polymer efudumeleyo ifumaneka emhadini wefom yokwahlula. Umoya ke uhlatywa ngenaliti kwiparison, eyongezela ukuhlengahlengisa imeko yomngxuma. Izibonelelo zokwenza isivuthelo zibandakanya isixhobo esisezantsi kunye nokukhaba iindleko zebhakethi, amazinga okudala ngokukhawuleza kunye nomthamo wokubumba iimilo ezintsonkothileyo kwisiqwenga esinye. Inqandekile, nangona kunjalo, ingenanto okanye iimilo zecylindrical.
Ikhalenda: Ikhalenda isetyenziselwa ukuvelisa amashiti e-thermoplastic kunye neemuvi kunye nokufaka izigqubuthelo zeplastiki kumqolo wezinto ezahlukeneyo. I-Thermoplastics ye-batter efana ne-consistency ayihoywa kwaye ukuqhubela phambili kweeroli ezifudumele okanye ezipholileyo. Iingenelo zayo ziquka iindleko eziphantsi nokuba amaphepha ahanjiswayo akhululwe kumaxhala. Isebenza kuphela kwimathiriyeli yamaphepha kwaye iimuvi ezincinci kakhulu azinakwenzeka.
Iyaphosa: Isakhelo sisetyenziselwa ukuhambisa amaphepha, imivalo, iityhubhu, imidaniso yangaphambili kunye nofakelo kunye nokukhusela iindawo zombane. Ngumjikelo osisiseko, ongafuneki mandla angaphandle okanye uxinzelelo. Imilo ilayishwa ngeplastiki ye-fluid (i-acrylics, i-epoxies, i-polyester, i-polypropylene, i-nylon okanye i-PVC ingasetyenziswa) kwaye emva koko ifudunyezwe ukulungisa, emva koko into ibe yi-isotropic (ineempawu ezifanayo ngale ndlela kwaye). Izibonelelo zayo zibandakanya: iindleko zemilo ephantsi, amandla okwenza isakhelo samalungu amakhulu aneenxalenye ezinqamlezileyo, ukugqitywa komphezulu ondilisekileyo kunye nokukhululeka kwawo ekudaleni umthamo ophantsi. Ngokudabukisayo, inqandelwe kwimo ephakathi ngokuthe ngqo kwaye ithande ukungabinaqoqosho kumazinga aphezulu okudala.
Ukubunjwa koxinzeleloI-Compression Molding isetyenziselwa ukuphatha iipholima ze-thermosetting. Intlawulo esele ilinganisiwe, eqhele ukwenziwa kwangaphambili yepolymer ivalwa ngaphakathi kwifomu evaliweyo kwaye ibonakaliswe kukuqina kunye noxinzelelo ide ithathe ubume bomngxuma wokumila kunye nokulungiswa. Nangona ixesha lenkqubo yokubunjwa koxinzelelo lide ngokusisiseko kunolo lokwenziwa kokufakwa kunye namacala anamacala amaninzi okanye ukuchasana okusondele kakhulu kunomngeni ukuzisa, bonwabele izibonelelo ezimbalwa kubandakanya nexabiso eliphantsi lendlu karhulumente (izixhobo kunye nehardware esetyenzisiweyo zithe tye ngakumbi kwaye Ixabiso eliphantsi), inkunkuma yezinto ezincinci kunye neenyani zokuba iindawo ezinkulu, ezinzima zinokubunjwa kwaye umjikelo uyaguquguquka ukukhawulezisa ikhompyuter.
Ukugxothwa: Ukugxothwa kusetyenziswa ukudibanisa okungayekiyo kwefilim, iphepha, iityhubhu, itshaneli, ifaneli, imivalo, amanqaku kunye nemicu kunye neeprofayili ezahlukeneyo kwaye ezinxulumene nokubunjwa kokuvuthela. I-polymer engumgubo okanye igranular thermoplastic okanye i-thermoset polymer iyakhathalelwa ukusuka kwisitya ukuya kwi-barrel efudumeleyo apho inyibilika khona kwaye emva koko ithunyelwe, njengomthetho ngesikrufu se-pivoting, nge-spout enecandelo elifanelekileyo lomnqamlezo. Ipholiswa ngokuchaphaza kwamanzi ize isikwe kobude obufanelekileyo. Umjikelo wokugxothwa uthambekele ekujongeni amaxabiso aphantsi esixhobo sawo, amandla okuphatha iimilo zeprofayile ezintsonkothileyo, ithuba lokwenziwa kwamazinga okudala ngokukhawuleza kunye nomthamo wokufaka i-coatings okanye ijacket kwiziko lemathiriyeli (njengocingo). Ithintelwe kwiindawo zecandelo lomnqamlezo ofanayo, nokuba kunjalo.
Isitofu sokubumba:Isitofu sokubumbayeyona ndlela idla ngokubandakanyeka ekwenzeni izinto zeplastiki ngenxa yamazinga aphezulu okudala kunye nomyalelo omkhulu kwimiba yezinto. (El Wakil, 1998) Kwesi sicwangciso, i-polymer ithathwa ngokunyamekelwa kwisitya kwi-pellet okanye isakhiwo somgubo ukuya kwigumbi apho ifudumala ukuya kwizinto ezininzi. Ithi ke inyanzeliswe ibe ngumngxunya-ubume bendlela yokwahlula-hlula kwaye iqina phantsi koxinzelelo, emva koko imilo iyavulwa kwaye inxalenye itsalwe. I-upsides ye-infusion forming mazinga aphezulu okudala, iindleko eziphantsi zomsebenzi, ukuveliswa kwakhona kwezinto ezifihlakeleyo ezintsonkothileyo kunye nokugqitywa okukhulu komphezulu. Izithintelo zizixhobo zokuqalisa eziphezulu kwaye zigqithise iindleko kunye nendlela engasebenzi ngayo ngokwemali kwimitsi encinci.
Ukubunjwa okujikelezayo: Ukubumba okujikelezayo ngumjikelezo apho izinto ezingenanto zinokuveliswa kwi-thermoplastics kwaye ngamanye amaxesha i-thermosets. Intlawulo yepolymer eyomeleleyo okanye enolwelo ifakwa kwimilo, ethi ifudunyezwe ngelixa kwangaxeshanye ijike iitomahawk ezimbini ezichaseneyo. Ngale ndlela, amandla eradial atyhala ipolymer kwiindonga zefom, ebumba umaleko wobunzima obufanayo obulungelelanisa ubume bomngxuma kwaye emva koko upholiswe kwaye uguqulwe ukusuka kwimilo. Unxibelelwano ngokubanzi lunobude obuphakathi komjikelo wexesha kodwa lonwabela izibonelelo zokunika ithuba lesicwangciso sezinto ezingenasiphelo kunye nokuvumela iinxalenye ezinzima ukuba zibunjwe kusetyenziswa izixhobo zexabiso ezincinci kunye nezixhobo.
Thermoforming: I-Thermoforming ibandakanya imijikelo eyahlukeneyo esetyenziselwa ukwenza izinto ezibunjiweyo zekomityi, umzekelo, iikhompatimenti, iibhodi, iindawo zokulala kunye neemonitha zomatshini ezivela kumaphepha e-thermoplastic. I-intensity relaxed thermoplastic sheet ibekwe phezu kobume kwaye umoya uthululwe phakathi kwezi zibini, unyanzelisa iphepha ukuba lilungelelanise kwifom yefom. Ipolymer ke ipholisiwe ukuze ibambe ubume bayo, isuswe kwifom kwaye iwebhu eyijikelezayo ilawulwa. Umgangatho we-thermoforming uquka: iindleko eziphantsi zezixhobo, ithuba lokuyilwa kwenxalenye enkulu eneendawo ezincinci kunye nokuba bubulumko rhoqo ekuyilweni kwenxalenye ethintelweyo. Nangona kunjalo ithintelwe kwinto yokuba amalungu kufuneka abe ngolungelelwaniso oluthe ngqo, kukho isivuno esikhulu seqhekeza, kukho izixhobo ezimbalwa ezinokuthi zisetyenziswe kunye nalo mjikelo, kwaye imeko yento ayinakuqulatha imivulo.
