Download or read book Precision Injection Molding written by Jehuda Greener and published by Hanser Publications. This book was released on 2006 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the key aspects of the production of high precision components is the need to meet extremely tight dimensional tolerances, typically in the submicron range, and maintain these tolerances over the practical lifetimes of the molded articles. In addition, as many of the precision components are utilized in various optoelectronic systems and devices, control of optical and electrical properties is often crucial. The strict control of dimensional and electro-optical properties requires a systematic reexamination of the conventional injection-molding process with special consideration of its impact on the dimensions and electro-optical characteristics of the molded article. This volume examines precision injection molding from different perspectives, covering materials, process and hardware aspects of the technology, with special emphasis on the dimensional integrity and stability of the molded components. Special topics covered in this volume include: dimensional stability of molded plastics, models for warpage development, compact disc molding, process control, crystallization phenomena in injection molding, micro-molding and microfluidics.

Each individual step, known as an unit manufacturing process, can be viewed as the fundamental building block of a nation's manufacturing capability. A committee of the National Research Council has prepared a report to help define national priorities for research in unit processes. It contains an organizing framework for unit process families, criteria for determining the criticality of a process or manufacturing technology, examples of research opportunities, and a prioritized list of enabling technologies that can lead to the manufacture of products of superior quality at competitive costs. The study was performed under the sponsorship of the National Science Foundation and the Defense Department's Manufacturing Technology Program.
