Iimveliso zePlastiki zenziwe ngomxube we-synthetic resin kunye nezongezelelo ezahlukeneyo njengezinto eziluhlaza, usebenzisa inaliti, i-extrusion, icinezela, ukugalela kunye nezinye iindlela. Ngelixa iimveliso zeplastiki zibunjwa, zikwafumana ukusebenza kokugqibela, ke ukubumba iplastiki yeyona nkqubo iphambili yokuvelisa.
1. I-injection molding ikwabizwa ngokuba yi-injection molding. Yindlela yokusebenzisa umatshini wokutofa ngokukhawuleza ukutofa iplastiki etyhidiweyo kwisingundo kwaye uyiqinise ukuze ufumane iimveliso zeplastiki ezahlukeneyo.
2. Indlela yokubumba i-extrusion yinkqubo esebenzisa i-screw rotation kunye noxinzelelo lokukhupha ngokuqhubekayo iplastiki yeplastiki kwi-mold, kwaye xa udlula ngendlela ethile yokufa, iprofayili yeplastiki efanelekileyo kwimilo yokufa ifunyenwe.
3. Ukunyanzeliswa kwe-compression, eyaziwa ngokuba yi-compression molding, i-compression molding, i-compression molding, njl., kukongeza iipellets eziqinileyo okanye iziqwenga ezenziwe ngaphambili kwi-mold, kwaye usebenzise ukufudumeza kunye noxinzelelo ukuze uthambe kwaye unyibilike, kwaye phantsi koxinzelelo Indlela yokuzalisa. umgodi wokungunda ukufumana iinxalenye zeplastiki emva kokunyanga.
4. Ukubumba ukuvuthela (okwenkqubo yesibini yeeplastiki) yindlela yokucubungula apho iiparini zeplastiki ezingenanto zivuthelwa kwaye zikhubazeke ngomoya oxinzelelweyo, kwaye iinxalenye zeplastiki zifunyenwe emva kokupholisa kunye nokubunjwa.
5. Ukuphoswa kweplastiki kufana nokuphosa isinyithi. Oko kukuthi, izinto ze-polymer okanye izinto ze-monomer kwimeko ehambayo ifakwe kwi-mold ethile, kwaye phantsi kweemeko ezithile, iphendulwa, iqiniswe, kwaye yenziwe ngendlela yokucubungula iinxalenye zeplastiki ezihambelana ne-mold cavity.
I-6.I-Gas-assisted injection molding (ebizwa ngokuba yi-gas-assisted molding) yindlela entsha kwintsimi yokucubungula iplastiki. Yahlulahlulwe yaba yi-hollow forming, shot short, kunye ne-full shot.
