INTRODUCTION1.1 BackgroundPolymers have various worthwhile properties such as high strength-to-weightratio, high flexibility, and high chemical and corrosion resistance, which make themsuitable for modern-day industrial and engineering applications. Polymers have notonly replaced metals in structural applications. But nowadays they are also used as asubstitute for glass in various optical applications. Automobile parts, aircraftwindshields, medical device enclosures and packaging telephones, human bodyprostheses, etc., are some of the polymer utilization examples [1] in daily life.Extrusion, injection molding, compression molding, blow molding, rotational molding,spinning, and thermoforming are the various polymer processing methods
