Plastic raw materials yakasimba kana elastomeric patembiricha yekamuri, uye zvinhu zvakabikwa zvinopiswa panguva yekugadziriswa kuti zvishandure kuita mvura, zvinwiwa zvakanyungudutswa. Plastiki inogona kukamurwa kuita "thermoplastics" uye "thermosets" zvichienderana nemaitiro avo ekugadzirisa.
"Thermoplastics" inogona kupiswa uye kuumbwa kakawanda uye inogona kushandiswa zvakare. Idzo dzine mvura yakaita sematope uye dzine mamiriro ekunyungudika zvishoma nezvishoma. Inowanzo shandiswa thermoplastics ndeye PE, PP, PVC, ABS, etc. Thermosets inosimbisa zvachose kana ichipisa uye yakatonhodzwa. Iyo molecular cheni inogadzira zvisungo zvemakemikari uye inova chimiro chakatsiga, saka kunyangwe ikapisa zvakare, haikwanise kusvika kune yakanyungudutswa yemvura. Epoxies uye rubber mienzaniso ye thermoset plastiki.
Aya anotevera mamwe marudzi akajairika uye ruzivo rwemapurasitiki ekugadzirisa maitiro: kukanda kwepurasitiki (kudonhedza kuumba, coagulation kuumba, kutenderera kuumbwa), kuvhuvhuta kuumbwa, epurasitiki extrusion, epurasitiki thermoforming (compression molding, vacuum kuumba), epurasitiki jekiseni kuumba, epurasitiki Welding (friction welding, laser welding), kupupa kwepurasitiki
