Introduction Plastic materials are commonly used in many areas of industry as they can meet various requirements due to their specific and wide variation of physical and chemical properties.
These are caused by many factors, which include the settings of the molding process parameters, the mold system, the part geometry as well as the plastic materials [1-2].
