Ukubumba isitofu, ngokuthetha nje, yinkqubo yokusebenzisa izinto zentsimbi ukwenza umngxuma okwimilo yenxalenye, ukufaka uxinzelelo kwiplastiki yolwelo olunyibilikisiweyo ukuyitofa kumngxuma kunye nokugcina uxinzelelo kangangexesha elithile, kwaye emva koko upholise iplastiki inyibilika kwaye ikhuphe inxalenye egqityiweyo. Namhlanje, makhe sithethe ngeendlela ezininzi eziqhelekileyo zokubumba.
1. Ugwebu
Ukubumba i-Foam yindlela yokucubungula eyenza isakhiwo esinamaqabunga ngaphakathi kweplastiki ngeendlela eziphathekayo okanye zekhemikhali.
Inkqubo:
a. Ukutya: Gcwalisa umngundo ngezinto ezikrwada ukuze zibe namagwebu.
b. Ukufudumeza kweClamping: Ukufudumeza kuthambisa amasuntswana, kuphunga i-ejenti ekhupha ugwebu kwiiseli, kwaye ivumela indawo yokufudumala ukuba ingene ukuze yandise ngakumbi imathiriyeli ekrwada. Ukubumba ke kuthintelwe ngumgodi wokungunda. Impahla ekrwada eyandisiweyo igcwalisa yonke indawo yokubumba kunye neebhondi ngokubanzi.
c. Ukupholisa ukubumba: Vumela imveliso ipholile kwaye ibonakaliswe.
Izinto eziluncedo:Imveliso inefuthe eliphezulu lokufakelwa kwe-thermal kunye nokuchasana kwempembelelo efanelekileyo.
Izinto ezingeloncedo:Iimpawu zokuqukuqela kweradial zenziwe lula phambi kokuhamba kwezinto. Nokuba lugwebu lwekhemikhali okanye i-micro-foaming, kukho amanqaku acacileyo okuhamba kweradial emhlophe. Umgangatho ongaphezulu wamalungu uhlwempuzekile, kwaye awufanelekanga kwiindawo ezineemfuno zomgangatho ophezulu.
2. Ukuphosa
Kwaziwa njengeukubumba ukubumba, inkqubo apho i-resin ye-resin ekrwada i-polymer edibeneyo ifakwe kwi-mold ukuze iphendule kwaye iqiniswe phantsi koxinzelelo oluqhelekileyo okanye indawo yoxinzelelo oluncinci. I-nylon monomers kunye ne-polyamides Ngokuhambela phambili kwetekhnoloji, ingcamango yokuphosa yendabuko itshintshile, kwaye izisombululo ze-polymer kunye ne-dispersions kuquka i-PVC pastes kunye nezisombululo nazo zingasetyenziselwa ukuphosa.
Ukubumba i-cast kwaqala ukusetyenziswa kwi-thermosetting resins kwaye kamva kwimathiriyeli ye-thermoplastic.
Inkqubo:
a. Ukulungiselela ukungunda: Ezinye zifuna ukufudunyezwa kwangaphambili. Coca ukungunda, sebenzisa kwangaphambili ukukhululwa kokungunda ukuba kukho imfuneko, kwaye ufudumeze kwangaphambili ukungunda.
b. Qwalasela ulwelo lokuphosa: Xuba imathiriyeli ekrwada yeplastiki, iarhente yokunyanga, i-catalyst, njl.
c. Ukuphosa kunye nokunyanga: Izinto ezikrwada zenziwe nge-polymer kwaye zinyangwa ekubumbeni ukuze zibe yimveliso. Inkqubo yokuqina igqityiwe phantsi kobushushu obuqhelekileyo bokushisa.
d. Ukumodareyitha: Ukwakhiwa emva kokunyanga kugqityiwe.
Izinto eziluncedo:Izixhobo ezifunekayo zilula kwaye akukho xinzelelo olufunekayo; iimfuno zamandla okubumba aziphezulu; imveliso ifana kwaye uxinzelelo lwangaphakathi luphantsi; ubukhulu bemveliso buncinci, kwaye izixhobo zoxinzelelo zilula; iimfuno zamandla okungunda ziphantsi; i-workpiece ifana kwaye uxinzelelo lwangaphakathi luphantsi, izithintelo zobungakanani bomsebenzi omncinci kwaye akukho zixhobo zoxinzelelo ezifunekayo.
Izinto ezingeloncedo:Imveliso ithatha ixesha elide ukwenza kwaye ukusebenza kakuhle kuphantsi.
Isicelo:Iiprofayili ezahlukeneyo, imibhobho, njl njl. I-Plexiglass yeyona mveliso iqhelekileyo yokuphosa iplastiki. I-Plexiglass yimveliso yokuphosa yeplastiki yakudala.
3. Ukubumba ukunyanzeliswa
Ikwabizwa ngokuba kukudluliselwa kwefilimu yeplastiki yokubumba, yindlela yokubumba iplastiki ye-thermosetting. I-workpiece iyaphiliswa kwaye yenziwe kwi-mold cavity emva kokufudumeza kunye nokucinezela kunye nokufudumeza.
Inkqubo:
a. Ukufudumeza ukutya: Tshisa kwaye uthambise izinto ezikrwada.
b. Uxinzelelo: Sebenzisa i-flap okanye iplunger ukucinezela imathiriyeli ekrwada ethambileyo netyhidiweyo kwisingundo.
c. Ukubumba: Ukupholisa kunye nokudilizwa emva kokwenza.
Izinto eziluncedo:Iibhetshi ezincinci zokusebenza, ukunciphisa iindleko zabasebenzi, uxinzelelo lwangaphakathi olufanayo, kunye nokuchaneka okuphezulu; ukunxitywa komngundo okuncinci kunokwenza iimveliso ezinokufakelwa okucokisekileyo okanye okomeleza ubushushu.
Izinto ezingeloncedo:Iindleko eziphezulu zokwenziwa kokungunda; ilahleko enkulu yezinto zeplastiki ekrwada.
