A na-arụpụta ọkpọkọ PVC site na extrusion nke akụrụngwa PVC, ma na-agbaso otu usoro nke arụ ọrụ extrusion ọkpọkọ:
1.Feeding nke raw material powder akpọ resin na filler n'ime PVC ejima ịghasa extruder;
2. Na-agbaze na kpo oku na otutu mpaghara extruder;
3. Extruding site na anwụ na-eme ka ọ bụrụ ọkpọkọ;
4.Cooling nke ọkpọkọ ekara (site na ịgbanye mmiri na ọkpọkọ);na
