Computer Modelling of Polymer Processing


Book Description

The use of computers to numerically analyse polymer processing was first reported as for back as the 1950's, and the first commercial software became available around 20 years ago. Much research has been carried out since that time, and this report aims to summarise contemporary trends in both commercial and academic research and development. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database provides useful references for further reading.

This book presents the proceedings of AMMCS 2022, the 2nd International Conference on Applied Mathematics, Modeling and Computer Simulation, held in Wuhan, China, on 13 and 14 August 2022, with online presentations available for those not able to attend in person due to continuing pandemic restrictions. The conference served as an open forum for the sharing and spreading of the newest ideas and latest research findings among all those involved in any aspect of applied mathematics, modeling and computer simulation, and offered an ideal platform for bringing together researchers, practitioners, scholars, professors and engineers from all around the world to exchange the newest research results and stimulate scientific innovation. More than 150 participants were able to exchange knowledge and discuss the latest developments at the conference. The book contains 127 peer-reviewed papers, selected from more than 200 submissions and ranging from the theoretical and conceptual to the strongly pragmatic; all addressing industrial best practice. Topics covered included mathematical modeling and application, engineering applications and scientific computations, and simulation of intelligent systems. The book shares practical experiences and enlightening ideas and will be of interest to researchers and practitioners in applied mathematics, modeling and computer simulation everywhere.




How to Make Injection Molds


Book Description

Economic success in the plastics processing industry depends on the quality, precision, and reliability of its most common tool: the injection mold. Consequently, misjudgments in design and mistakes in the manufacturing of molds can result in grave consequences. This comprehensive handbook for the design and manufacture of injection molds covers all aspects of how to successfully make injection molds from a practical as well as from a theoretical point of view. It should serve as an indispensable reference work for everyone engaged in mold making. "...an example of how books should be written ... will be used by molders, mold designers and mold makers and will become a standard." (Polymer News) Contents: · Materials for Injection Molds · Mold Making Techniques · Estimating Mold Costs · The Injection Molding Process · Design of Runner Systems · Design of Gates · Venting of Molds · Heat Exchange System · Shrinkage · Mechanical Design · Shifting of Cores · Ejection · Alignment and Changing of Molds · Computer-Aided Mold Design and Construction · Maintenance of Injection Molds · Measuring in Injection Molds · Temperature Controllers · Mold Standards · Correction of Molding Defects · Special Processes - Special Molds




Injection Molding Handbook


Book Description

This third edition has been written to thoroughly update the coverage of injection molding in the World of Plastics. There have been changes, including extensive additions, to over 50% of the content of the second edition. Many examples are provided of processing different plastics and relating the results to critiCal factors, which range from product design to meeting performance requirements to reducing costs to zero-defect targets. Changes have not been made that concern what is basic to injection molding. However, more basic information has been added concerning present and future developments, resulting in the book being more useful for a long time to come. Detailed explanations and interpretation of individual subjects (more than 1500) are provided, using a total of 914 figures and 209 tables. Throughout the book there is extensive information on problems and solutions as well as extensive cross referencing on its many different subjects. This book represents the ENCYCLOPEDIA on IM, as is evident from its extensive and detailed text that follows from its lengthy Table of CONTENTS and INDEX with over 5200 entries. The worldwide industry encompasses many hundreds of useful plastic-related computer programs. This book lists these programs (ranging from operational training to product design to molding to marketing) and explains them briefly, but no program or series of programs can provide the details obtained and the extent of information contained in this single sourcebook.




International Conference on Manufacturing Automation


Book Description

The proceedings of the fourth ICMA in 2004 represent a huge contribution to research in this area. Everyone attending the conference was asked to submit their papers electronically which meant that 100 top quality papers from no less that 10 different countries contributed to the theme of the conference.




Computer Applications in Near Net-Shape Operations


Book Description

Having edited "Journal of Materials Processing Technology" (previously entitled "Journal of Mechanical Working Technology") for close on 25 years, I have seen the many dramatic changes that have occurred in the materials processing field. Long gone are the days when the only "materials processing" carried out was virtually the forming of conventional metals and alloys, and when the development of a new product or process in a great number of cases called for several months of repetitive trial-and-error,' with many (mostly intuition- or experience-based) expensive and time-consuming modifications being made to the dies, until success was achieved. Even when a 'successful' product was formed, its mechanical properties, in terms of springback and dimensional accuracy, thickness variations, residual stresses, surface finish, etc. , remained to be determined. Bulk-forming operations usually required expensive machining to be carried out on the product to impart the required dimensional accuracy and surface fmish. Over the years, the experience-based craft of metal forming has given way to the science of materials processing. With the use of the computer, forming operations can be simulated with accuracy, to determine the best forming route and the associated forming loads and die stresses, and to predict the mechanical properties of the formed product, even down to its surface texture.




Flow Analysis of Injection Molds


Book Description

Given the importance of injection molding as a process as well as the simulation industry that supports it, there was a need for a book that deals solely with the modeling and simulation of injection molding. This book meets that need. The modeling and simulation details of filling, packing, residual stress, shrinkage, and warpage of amorphous, semi-crystalline, and fiber-filled materials are described. This book is essential for simulation software users, as well as for graduate students and researchers who are interested in enhancing simulation. And for the specialist, numerous appendices provide detailed information on the topics discussed in the chapters.
