INTRODUCTION
1.1 Background
Polymers have various worthwhile properties such as high strength-to-weight
ratio, high flexibility, and high chemical and corrosion resistance, which make them
suitable for modern-day industrial and engineering applications. Polymers have not
only replaced metals in structural applications. But nowadays they are also used as a
substitute for glass in various optical applications. Automobile parts, aircraft
windshields, medical device enclosures and packaging telephones, human body
prostheses, 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
