Extrusion e ka ba mokhoa oa tlhahiso oo ka oona vinyl e qhibilihang ebe e bōptjoa ho ba profil. Extrusion e fana ka lintho tse kang ho hlobolisa boemo ba leholimo, li-tubing, terata, litšepe tsa mokatong, litšoantšo tsa lifensetere tsa lifensetere le lilaete tsa sheeting, le lisebelisoa tsa cable insulating.

Mokhoa o latelang o qala ka ho ja lintho tsa polasetiki (limela, li-granules, phofo kapa li-sprays) ho tsoa ka har'a hopper ho ea letamong la extruder. Lesela lena le petelitsoe liphaepheng ka motlakase ka li-screw tse entsoeng.
Lintho tse Tloaelehileng tsa Extrusion
