Control technology assessment of plastics processing plants

A nually pproximately 12 million metric tons of plastic resins are processed anin the U.S. by more than 7000 plastics processing plants. Many types of resins, chemicals, and additives are combined to produde finished products through a variety of process operations such as adhesives production, coating, extrusion, film and sheet production, foam generation, lamination, and molding.

Welding of Plastics: Fundamentals and New Developments

This paper provides a general introduction to welding fundamentals (section 2) followed by sections on a few selected welding processes that have had significant developments or improvements over the last few years. The processes that are discussed are friction welding (section 3), hot plate welding (section 4), ultrasonic welding (section 5), laser/IR welding (section 6), RF welding (section 7...

Laser transmission welding of transparent plastics parts in micro technology

Most welding processes for plastics do not meet the special demands of micro technology. Laser transmission welding, however, features distinctive advantages like low mechanical and thermal load of the joining parts. Hence it is particularly suitable for the welding of micro plastics parts. Certain optical properties of the components to be welded are needed though. While one of the welding par...

The Effects of Radiation Sterilization on Plastics

remainder of this discussion the term radiation will be used to mean both high-energy electrons and gamma rays except where an explicit distinction is made.
