ABSTRACT
The article explains the myths and facts on the plastic extrusion process. Profile on the process is depicted on temperature configurations on the barrel, where application on materials and products depend on the extruder in terms of its operation time, material used, and viscosity variation. Plastics being bad for nature has been a misconception due to various benefits of it including providing lightweight products, water-resistance, and holding wastes.
