Precision Injection Molding by Jehuda Greener,Reinhold Wimberger-Friedl Pdf

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.

Micro Injection Molding by Guido Tosello Pdf

"Micro Injection Molding" meets the need for a dedicated book dealing exclusively with micro injection molding and overcoming the challenges of managing and processing polymer materials at ultra-small scales. Micro injection molding is the primary process for the mass production of polymer components with critical dimensions in the sub-millimeter range; however, it is not just a simple downscaling of conventional injection molding, and specific material-process-product interactions must be understood in order to achieve near zero-defect net-shape micro molded products. Micro molding is typically associated with ultra-high accuracy and superior process capabilities. Micro molded products have dimensional tolerances down to the single-digit micrometer range and surface finish with roughness from the sub-micrometer down to a few nanometers range. Micro and nano-structured tool surfaces are reproduced with very high replication fidelity onto the polymer products. Micro injection molding is highly suitable for the manufacture of multifunctional micro components such as micro implants, microfluidic systems, polymer micro optical elements, and micro mechanical systems. This book provides engineers, project managers, researchers, consultants, and other professionals involved in precision polymer processing and micro manufacturing with a comprehensive, up-to-date, and detailed treatment of the main topics related to micro molding, from material and process technology to tooling, to key-enabling technologies, and multimaterial process variations. Contents: • Part 1 – Polymer Materials and Process Micro Technology: micro injection molding machines technology; micro molding process monitoring and control; polymer materials structure and properties in micro injection molding parts; surface replication in micro injection molding • Part 2 – Tooling Technologies for Micro Mold Making: micro machining technologies for micro injection mold making; ultra-precision machining technologies for micro injection mold making; surface treatment of mold tools in micro injection molding • Part 3 – Micro Molding Key-Enabling Technologies: vacuum-assisted micro injection molding; modeling and simulation of micro injection molding; metrological quality assurance in micro injection molding; additive manufacturing for micro tooling and micro part rapid prototyping • Part 4 – Multimaterial Micro Processing: micro powder injection molding; multimaterial micro injection molding

Injection Molding Handbook by D.V. Rosato,Marlene G. Rosato Pdf

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.

Handbook of Thermoplastics Injection Mould Design by P.S. Cracknell,R.W. Dyson Pdf

Injection moulding is one of the most important methods of manufacturing plastics products. Through the development of sophisticated micro processor control systems, the modern injection moulding machine is capable of producing precision mouldings with close tolerances in large numbers and with excellent reproducibility. This capability, however, is often limited by the lack of a proper appreciation of mould design. The mould, or tool as it is often called, is at the heart of the injection moulding process. Its basic function is to accept the plastic melt from the injection unit and cool it to the desired shape prior to ejection. It is not, however, simply a matter of the mould having an impression of the shape to be moulded. Many other factors have to be taken into account - for example, the ability to fill the mould impression properly and efficiently without inducing weaknesses in the moulding and the efficient cooling of the moulding in order to maximise production rates without diminishing the quality of the moulding. In addition, the type of mould, gate and runner system, and ejection system which will best meet the needs of a particular job specification have to be determined. In our experience lack of attention to such factors leads to the mould limiting the ability of the injection moulding machine and preventing the process as a whole from achieving its true potential.

Injection Molding by Rong Zheng,Roger I. Tanner,Xi-Jun Fan Pdf

This book covers fundamental principles and numerical methods relevant to the modeling of the injection molding process. As injection molding processing is related to rheology, mechanical and chemical engineering, polymer science and computational methods, and is a rapidly growing field, the book provides a multidisciplinary and comprehensive introduction to the subjects required for an understanding of the complex process. It addresses the up-to-date status of fundamental understanding and simulation technologies, without losing sight of still useful classical approaches. The main chapters of the book are devoted to the currently active fields of flow-induced crystallization and orientation evolution of fiber suspensions, respectively, followed by detailed discussion of their effects on mechanical property, shrinkage and warpage of injection-molded products. The level of the proposed book will be suitable for interested scientists, R&D engineers, application engineers, and graduate students in engineering.
