Ngokwendlela yokwenza i-parison, ukubunjwa kokuvuthela kunokwahlulwa kube yi-extrusion blow blowing kunye ne-injection blow blowing.Ezi zisanda kuphuhliswa ziquka ukubunjwa kwe-multi-layer blow and stretch blow molding.Uthini umahluko phakathi kwezi zakhiwo zimbini?
I-Extrusion, ekwabizwa ngokuba yi-extrusion blow molding, yindlela yokusebenzisa i-extruder (extruder) ukugqithisa ngokulandelelana intlaka eshushu ngokufa ukukhupha imveliso yobume obufunwayo.I-Extrusion iphinda isetyenziswe ngamanye amaxesha ekubunjweni kwee-thermosets kwaye ingasetyenziselwa ukubunjwa kweeplastiki ezinogwebu.
Inzuzo yokubumba i-extrusion blowing kukuba inokukhupha iimveliso zeemilo ezahlukeneyo, kunye nokusebenza kakuhle kwemveliso, kwaye iyakwazi ukuzenzekelayo kunye nemveliso eqhubekayo;into engalunganga kukuba iiplastiki ze-thermosetting azikwazi ukuqhutyelwa ngokubanzi ngale ndlela, kwaye ubungakanani bemveliso buxhomekeke ekuthandeni.
Ukubumba isitofu kukwabizwa ngokuba kukubumba ukuvuthela ngesitofu.Isitofu sokubumba yindlela yokusebenzisa umatshini wokubumba umtshini (okanye umatshini wokutofa) ukufaka i-thermoplastic inyibilika kwi-mold phantsi koxinzelelo oluphezulu, kwaye emva koko upholise kwaye uqinise ukufumana imveliso.Isitofu sokubumba singasetyenziselwa ukubumba i-thermosets kunye ne-foam.
Iingenelo zokubumba inaliti kukuba isantya sokuvelisa sikhawuleza, ukusebenza kakuhle kuphezulu, ukusebenza kunokwenziwa ngokuzenzekelayo, kwaye kunokwenza iinxalenye ezinemilo enzima, efanelekileyo ngakumbi kwimveliso emininzi.Ukungalungi kukuba iindleko zezixhobo kunye nokubumba ziphezulu, kwaye ukupheliswa koomatshini bokubumba inaliti kunzima.
Ukubumba ukuvuthela kukwabizwa ngokuba kukubumba umgongxo okanye ukubumba umgongxo.Ukubumba ukuvuthela yindlela yokufaka umoya kwiparison yentlaka eshushu evalwe kwisingundo ibe yimveliso engumgongxo ngoxinzelelo lomoya oxinanisiweyo.Ukubumba ukuvuthela kubandakanya iindlela ezimbini zokuvuthela ifilimu kunye nokuvuthela iimveliso ezingenanto.Iimveliso zefilimu, iibhotile ezahlukeneyo, imigqomo, iijagi kunye nezinto zokudlala zabantwana zinokuveliswa ngokubumba ukubetha.
Umzekelo, kutheni ibhotile inokusebenzisa inkqubo yokubumba kuphela, kodwa inokusebenzisa isitofu sokubumba?Isizathu kukuba indawo yangaphakathi yebhotile inkulu kwaye umlomo webhotile uncinci, ngoko ke i-injection yokubumba ingundoqo ayikwazi ukukhutshwa.Ke ngoko, vuthela abavelisi besandwich iplastiki ethambileyo inyibilika embindini wokungunda kwaye uyivuthele ukuze ibambelele kudonga lwangaphakathi lomngundo ngaphandle kokusebenzisa undoqo.
