Iimveliso zeplastiki zenziwe ngomxube we-resin yokwenziwa kunye nezinye izongezo njengezinto eziluhlaza, kusetyenziswa i-injection, extrusion, pressing, pouring kunye nezinye iindlela. Ngelixa iimveliso zeplastiki zibunjwa, zikwafumana ukusebenza kokugqibela, ngoko ke ukubumba iplastiki yinkqubo ephambili yemveliso.
1. Ukubumba ngenaliti kukwabizwa ngokuba kukubumba ngenaliti. Yindlela yokusebenzisa umatshini wokubumba ukufaka iplastiki enyibilikisiweyo ngokukhawuleza kwisikhunta uze uyiqinise ukuze ufumane iimveliso ezahlukeneyo zeplastiki.
2. Indlela yokubumba i-extrusion yinkqubo esebenzisa ukujikeleza kwezikrufu kunye noxinzelelo ukuze kuqhutyekwe kukhutshwe iplastiki eyenziwe ngeplastiki kwi-mold, kwaye xa kudlula kwimo ethile ye-die, kufunyanwa iprofayili yeplastiki efanelekileyo kwimo ye-die.
3. Ukubumba ucinezelo, okwaziwa ngokuba kukubumba ucinezelo, ukubumba ucinezelo, ukubumba ucinezelo, njl.njl., kukongeza iipellets eziqinileyo okanye iziqwenga ezenziwe ngaphambili kwisikhunta, kwaye kusetyenziswe ubushushu kunye noxinzelelo ukuzithambisa nokuzinyibilikisa, kwaye phantsi koxinzelelo. Indlela yokuzalisa umngxuma wesikhunta ukuze kufumaneke iindawo zeplastiki emva kokunyibilika.
4. Ukubumba nge-blow (okuyinkqubo yesibini yokucubungula iiplastiki) yindlela yokucubungula apho iiparison zeplastiki ezingenanto zivuthelwa kwaye ziguqulwe ngomoya ocinezelweyo, kwaye iindawo zeplastiki zifunyanwa emva kokupholisa nokubumba.
5. Ukuphoswa kweplastiki kufana nokuphoswa kwesinyithi. Oko kukuthi, izinto zepolymer okanye izinto ze-monomer ezikwimeko yokugeleza zifakwa kwisikhunta esithile, kwaye phantsi kweemeko ezithile, ziyasabela, ziqiniswe, kwaye zenziwe ngendlela yokucubungula iindawo zeplastiki ezihambelana nomgodi wesikhunta.
6. Ukubumba inaliti encediswa yigesi (okubizwa ngokuba kukubumba ipetroli encediswa yigesi) yindlela entsha kwicandelo lokucubungula iplastiki. Yahlulwe yaba yi-hollow forming, short shot, kunye full shot.
