Izinto zeplastiki ekrwada ziqinile okanye i-elastomeric kwiqondo lobushushu begumbi, kwaye imathiriyeli ekrwada iyafudunyezwa ngexesha lokulungiswa ukuze ijike ibe lulwelo olunyibilikisiweyo. Iiplastiki zinokwahlulwa zibe "zii-thermoplastics" kunye ne "thermosets" ngokweempawu zabo zokusebenza.
"I-Thermoplastics" inokufudunyezwa kwaye ibunjwe ngamaxesha amaninzi kwaye ingaphinda isetyenziswe. Zilulwelo olufana neslime kwaye zinemeko ecothayo yokunyibilika. I-thermoplastics esetyenziswa ngokuqhelekileyo yi-PE, PP, PVC, ABS, njl. I-Thermosets iqinisa ngokusisigxina xa ishushu kwaye ipholile. Itsheyina lemolekyuli libumba imibhobho yeekhemikhali kwaye liba sisakhiwo esizinzileyo, ngoko ke nokuba liphinde lifudunyezwe, alikwazi ukufikelela kulwelo olunyibilikisiweyo. Ii-epoxies kunye neerubha ziyimizekelo yeeplastiki ze-thermoset.
Ezi zilandelayo zezinye iindidi eziqhelekileyo kunye neenkcukacha zeenkqubo zeplastiki: ukuphosa iplastiki (ukubumba ukulahla, ukubumba ukubumba, ukubumba okujikelezayo), ukubunjwa kokuvuthela, i-plastiki extrusion, i-thermoforming yeplastiki (i-compression molding, i-vacuum forming), ukubunjwa kweplastiki yeplastiki, i-Welding yeplastiki (i-friction ukuwelda, ukuwelda ngelaser), ugwebu lweplastiki
