Design Formulas for Plastics Engineers (Hanser Publishers),Used
Delivery time: 8-12 business days (International)
Design formulas and the mathematical models they yield are widely used in creating today's computer programs for designing machines and industrial dies. However the predictions of these programs do not always agree with the practical results. It is therefore essential that engineers have access to the formulas on which mathematical models are based in order to improve existing computer programs or develop entirely new ones. Plastics engineers in particular need a simple way to search for appropriate equations since they often deal with several different fields of engineering. By drawing together formulas from these fields, this book makes it easier to write computer design programs and to change existing ones in order to obtain a better fit with experimental results. The formulas are classified according to subject: rheology, thermodynamics, heat transfer, and part design. Each chapter covers the relevant relations in a particular field. A separate chapter is devoted to the practical equations for designing extrusion and injection molding equipment. Numerous thoroughly workedout problems illustrate the use of the formulas.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
