Seminar BenefitsThis course will bring together in a cohesive manner the interrelationships among material properties, fabrication process, and end-use properties.Polyethylene Terephthalate (PET) has become the material of choice for many new applications in the food and beverage, medical and pharmaceutical , household and chemical, and electronic and automotive markets. The end-use applications of PET are found in rigid and flexible packaging, composite molded structures, tapes and discs of various kinds. The fabrication processes include: injection molding, blow molding, extrusion, thermoforming, and film orientation. The ease of fabrication, the quality of the fabricated products, and the end-use properties are all dependent on basic material properties and specific responses during the various steps of each of the processing methods used to convert PET pellets into the desired final product.The technical information presented is based in part on systematic studies which have been carried out by the course instructor for the last 30 years, along with information extracted from textbooks and professional journals.Staying up-to-date with current PET Technology can offer significant cost benefits for your organization. It is essential to decision-making for PET purchasing, processes, problems and solutions, and how these decisions can affect your bottom line. This seminar will benefit:· Processing Engineers· Production Managers· Quality Control Managers· Chemists and Chemical Engineers· Designers and Packaging Engineers
