inkcazelo

Ukubumba inaliti yeplastiki yinkqubo yokuvelisa ebandakanya ukunyibilikisa iipeliti zeplastiki zentlaka kwaye uzitofe kwimbumba ukuvelisa imilo ethile okanye ifom. Inkqubo yokubumba inaliti ibandakanya ukutofa iplastiki enyibilikisiweyo kuxinzelelo oluphezulu kumngxunya owenziwe ngentsimbi. Emva kokuba iplastiki enyibilikisiweyo igcwalise umngxuma wokungunda kwaye ithathe ubume bayo, iyaphola kwaye iqine. Emva koko, umenzi ukhupha inxalenye egqityiweyo kwi-mold.

Imbali yokuBunjwa kwePlastiki yesitofu

Inkqubo yokubumba inaliti yeplastiki yaqala ukuveliswa ngoo-1930 ngusokhemisti waseJamani u-Otto Bayer. Wafumanisa ukuba iipolymers zinokunyibilika zize zibunjwe ngokweendlela ezahlukeneyo. Kwiminyaka elandelayo, abavelisi bayiphucule inkqubo ngokuphuhlisa oomatshini bokubumba benaliti abakumgangatho ophezulu kunye nokusebenzisa imathiriyeli ephucukileyo. Namhlanje, ukubumba inaliti yeplastiki yinkqubo yokuvelisa esetyenziswa ngokubanzi evelisa uluhlu olubanzi lweemveliso zeplastiki, ukusuka kwizinto zokudlala ezilula ukuya kwizixhobo zonyango ezinzima.

Inkqubo yokuBumba isitofu sePlastiki

Ukubumba inaliti yeplastiki yinkqubo enzima ebandakanya amanyathelo amaninzi kunye namacandelo. Nazi ezinye iinkcukacha malunga nenkqubo yokubumba inaliti yeplastiki:

Iziseko zeNkqubo

Inkqubo yokubumba inaliti yeplastiki ibandakanya amanyathelo amathandathu asisiseko: ukugoba, inaliti, indawo yokuhlala, ukupholisa, ukuvulwa kokungunda, kunye nokukhupha. Ngethuba lesigaba sokudibanisa, i-mold ivaliwe kwaye ibanjwe phantsi koxinzelelo. Ngethuba lesigaba sokutofa, umenzi ufaka iplastiki kwi-mold. Ngexesha lesigaba sokuhlala, iplastiki ipholisa kwaye iqina ngaphakathi kwesikhunta. Emva kokuba iplastiki yomelele, umenzi uvula ukungunda aze akhuphe inxalenye egqityiweyo.

Amacandelo Angundoqo oMatshini wokuBumba ngesitofu sePlastiki:

Umatshini wokubumba weplastikhi wokubumba unamalungu amakhulu amane: iyunithi yokutofa, iyunithi yokubambelela, ukungunda kunye nomlawuli. Iyunithi ye-injection inoxanduva lokunyibilikisa iplastiki kunye nokuyifaka kwi-mold, kunye neqela le-clamping libamba i-mold ngexesha lenkqubo yokutofa. Umngundo ngumgodi apho iplastiki itofwayo kwaye ithatha ukumila kwayo kokugqibela. Umlawuli ulawula ukusebenza komatshini kwaye ubeka iliso kwiiparamitha zenkqubo.
