1. Extrusion blow blowing
I-Extrusion blow blowing yenye yezona ndlela zisetyenziswa kakhulu kwizikhongozeli zokupakisha zeplastiki.I-powder (okanye i-granular material) yeplastiki ye-thermosetting iyancibilika nge-extruder, kwaye emva koko yenziwe ibe yi-hot-melt tubular parison ngokwethubhu ekhethekileyo yezinto.Xa i-parison idlula ubude obusetyenzisiweyo, i-parison ingena kwi-mold, i-mold ivaliwe, kwaye emva koko ivuthelwe.
Iimpawu zale ndlela yokubumba zezi: ukusebenza kakuhle okuphezulu, ubushushu obulungeleleneyo beparison, uluhlu olubanzi oluvumelekileyo lokumila, ubungakanani kunye nobukhulu bodonga lwesitya esingenanto, ukuguquguquka okunamandla, amandla aphezulu oxinzelelo lwenkqubo yokubumba, oomatshini abalula kunye nezixhobo, kunye nezantsi. utyalo-mali lobunjineli.Nangona kunjalo, ukuchaneka komsebenzi wezandla akuphezulu.Umgodi wangaphakathi wentambo yangaphandle uya kutshintsha kunye nokutshintshwa kwentambo yangaphandle phezu komhlaba.Kukho i-patchwork seam ezantsi kwesikhongozeli.
2. Ukubumba isitofu sokuvuthela
Isitofu ukuvuthela ukubumba usebenzisa umatshini weplastiki ukutofa intolongo kwi mandrel.Emva kokuba i-parison ipholile ngokuphakathi, i-mandrel kunye ne-parison zityiswa kwisixhobo sokubumba.Isixhobo sokubumba sicinezela i-mandrel kunye nomoya owaziswayo ivaliwe kwaye ixinzelelwe ukuze I-parison ikhulise kwaye ivelise imisebenzi yezandla eziyimfuneko, kunye neempahla zisuswe emva kokuba zifakwe efrijini kwaye ziqiniswe.
Iimpawu zale ndlela yokubumba: akukho zithungo kwimisebenzi yezandla, akukho mfuneko yokulungiswa kamva, ukuchaneka okuphezulu kwemicu yangaphandle kunye nezithinteli zebhotile, i-cavity yangaphakathi yentloko kunye nentamo ikwisangqa esigudileyo, umthamo wokuvelisa unokuba omkhulu, kukho oomatshini abancedisayo abambalwa kunye nezixhobo, kwaye amandla acinezelayo emazantsi emveliso aphezulu, ukusetyenziswa kwezinto eziphantsi ekrwada, ubukhulu bodonga obufanayo, kunye nokusebenza kakuhle kokuvelisa.Nangona kunjalo, utyalo-mali kwiiprojekthi zezixhobo zoomatshini mkhulu, umjikelo wemveliso mde, iimfuno zabaqhubi abasebenzayo ziphezulu, ukubonakala akufuneki kube nzima kakhulu, kwaye ukucaciswa kwesikhongozelo kuncinci, ngoko ke kufanelekile ukwenza ubungakanani obuncinci naphakathi. izitya ezichanekileyo.
3. Ukubumba isivuthelo esolula
Indlela yokubumba kukusebenzisa intonga eyolulayo ukwenza ukolula kwe-radial kwaye kwangoko uqhube ukubumba ukuvuthela.Ukongezelela, ngexesha lenkqubo yokubumba, i-macromolecules ye-biological icwangciswe ngocwangco kwiindonga zomzobo, ngaloo ndlela iphucula kakhulu ukusebenza kwesitya seplastiki.
Iimpawu zale ndlela yokubumba zezi: izinga eliphantsi lesiphako, ukusebenza kakuhle kokuvelisa, ukulawula ngokulula ubunzima bobunzima, ubunzima obuphezulu bokuqhekeka, ukuqina okuphuculweyo, ukuhambelana okuphuculweyo kunye nokugudiswa kwemisebenzi yezandla, kunye nomqobo olungileyo kunye neempawu zokutywina, kodwa iimfuno zolawulo lobushushu lokolula. ziphezulu ngokwentelekiso, kwaye utyalo-mali koomatshini kunye nezixhobo luninzi kakhulu.
