Kubumba yinchubo yekwenta tinhlobo letehlukene tema polymers (ema powders, ema pellets, tisombululo noma kusakateka) kube yimikhicito ngendlela lefunwako. Kuyintfo lebaluleke kakhulu kuyo yonkhe inchubo yekubumba tintfo tepulasitiki futsi kukhicitwa kwato tonkhe tintfo te polymer noma emaphrofayli. Inchubo ledzingekako. Tindlela tekubumba ngepulasitiki tifaka ekhatsi kubumba ngekukhipha, kubumba ngekujova, kubumba ngekucindzetela, kubumba kwekudlulisela, kubumba nge-laminate, kubumba ngekushaya, kubumba kwekhalenda, kubumba ngegwebu, kubumba ngekushisa kanye naletinye tindlela letinyenti, tonkhe letinekuvumelana kwato.
Kubumba ngekushisa yindlela yekwakha imikhicito kusetjentiswa emashidi e-thermoplastic njengetintfo letiluhlata, letingabangelwa kubunjwa kwesibili kwemapulasitiki. Kwekucala, lelishidi lisikwe libe ngusayizi lotsite kanye nesimo libekwa kuhlaka lwesikhunta, bese lishiswa libe sesimeni lesiphakeme se-elastic emkhatsini we-Tg-Tf, lelishidi liyalulwa ngesikhatsi lishiswa, bese umfutfo usetjentiswa kwenta kutsi usondzele esikhundleni Lesimo sesimo sifana nesimo sesikhunta cantained, kanye ne. Ngesikhatsi se thermoforming, umfutfo losetjentiswako usekelwe kakhulu emehlukweni emfutfo lowakhiwa ngekuhlanta kanye nekwetfula umoya locindzetelekile kutotimbili tinhlangotsi telishidi, kepha futsi ngekusebentisa umfutfo wemshini kanye nemfutfo we hydraulic.
Sici se thermoforming kutsi umfutfo wekwakha uphansi, futsi inchubo ye thermoforming injalo:
ibhodi (lishidi) tintfo → kucindzetela → kushisa → kucindzetela → kupholisa → kubumba → imikhicito leseyiphelile → kupholisa → kusika. Le thermoforming yemkhicito lophelile ihlukile kubuchwepheshe bekucubungula sikhatsi sinye njengekubumba ngekujova kanye nekukhipha. Akusiko kwe resin yepulasitiki noma ema pellets ekushisa kubumba noma kubumba lokuchubekako ngesigaba lesifanako sekuphambana nge die; futsi akusebentisi emathulusi emishini, emathulusi kanye naletinye tindlela tekucubungula ngemshini kusika incenye yalentfo yepulasitiki. Ngemuva kwaloko, kutfola kwakheka lokudzingekako kanye nebukhulu, kepha kwebhodi yepulasitiki (lishidi) lemphahla, kushisa, kusebentisa sikhunta, i-vacuum noma kucindzetela kukhubata ibhodi (lishidi) lemphahla. Finyelela kwakheka lokudzingekako kanye nebukhulu, lokungetiwe ngetinchubo letisekelako, kufeza injongo yesicelo.
Lobuchwepheshe be-thermoforming butfutfukiswa ngekusebentisa indlela yekwakha ishidi lensimbi. Noma sikhatsi sayo sekutfutfuka singasidze, kepha sivinini sekucubungula siyashesha, lizinga lekusebenta ngekuzenzakalela liphakeme, sikhunta sishibhile futsi kulula kusifaka esikhundleni, futsi nekuvumelana nesimo kucinile. Ingakhicita imikhicito lemikhulu njengetincenye tetindizamshini netimoto, lemincane njengetinkomishi tetinatfo. Tintfo letisele kulula kutiphindze tisebentise. Ingacubungula emashidi lamancane njenga 0.10mm ngebukhulu. Lamashidi angaba sobala noma angabonakali, abe yi crystalline noma angabonakali. Emaphethini angaphrintwa kulelishidi kucala, noma emaphethini lanemibala lekhanyako angaphrintwa ngemuva kwekubumba.
Eminyakeni lengu-30 kuya ku-40 leyengcile, ngenca yekukhula kwetinhlobonhlobo tetintfo te-thermoplastic ishidi (ishidi) njengetintfo letiluhlata, kwenta ncono lokuchubekako kwemishini yenchubo ye-thermoforming, kanye nekusetjentiswa lokubanti kwemikhicito, tebuchwepheshe be-thermoforming butfutfukile Ngekutfutfuka lokusheshako, intfutfuko yayo perfect more kanye ne-equip. Nawucatsanisa nekubumba ngekujova, i-thermoforming inetinzuzo tekusebenta kahle kwekukhicita lokusezingeni leliphakeme, indlela lelula, kutjala imali lencane yemishini, kanye nemandla ekukhicita imikhicito lenetindzawo letinkhulu. Nomakunjalo, tindleko te thermoforming tintfo letiluhlata tiphakeme, futsi kunetindlela letiningi tekucubungula ngemuva kwekucubungula imikhicito. Ngekutfutfukiswa lokuchubekako kwebuchwepheshe bekukhicita kanye nesidzingo sekukhulisa tinzuzo temnotfo, imishini ye-thermoforming kancane kancane isuse leyo yangaphambilini kuphela njengebhodi lepulasitiki lelizimele (ishidi) luhlelo lwekubumba tintfo, futsi seyicale kuhlanganiswa naletinye tintfo tekukhicita kuhlangabetana nekwakheka A umugca wekukhicita lophelele wekunciphisa tidzingo letitsite te-emprovci lapho. umkhicito wekugcina.
Kubumba ngekushisa ilungele kakhulu kwenta imikhicito lenetindvonga letincane kanye netindzawo letinkhulu letingetulu. Tinhlobo temapulasitiki letivame kusetjentiswa tifaka ekhatsi i-polystyrene, i-plexiglass, i-polyvinyl chloride, i-abs, i-polyethylene, i-polyethylene, i-polyethylene, i-polyethylene kanye ne-polyethylene terephthalate.
