Book SynopsisSingle-screw or twin-screw extruder? When the need to produce a homogeneous polymer melt occurs in the industrial environment, both product attributes and equipment cost must be evaluated. For many applications both the single and twin-screw extruder will produce the desired homogeneous melt needed to form the product through an extrusion die. Some applications such as dispersive mixing of solids in a polymer matrix are best accomplished in a twin-screw extruder. On the other hand, applications involving chemical reactions, color concentrate distributive mixing, and in line polymer-polymer distributive mixing can be accomplished with either device.However, for the same production rate, twin-screw extruders are generally more expensive than single-screw extruders with a diameter less than 200 mm. Therefore, a thorough understanding is needed for the concepts of solids conveying, melting, and mixing for the two types of extruders to make appropriate process acquisition decisions. This book covers engineering and technology concepts that should aid the practitioner in comparing these two types of extrusion equipment relative to process requirements.The handbook is intended for newcomers interested in the theoretical and regulatory aspects of validation and for thermal analysis practitioners who have to validate their equipment and methods.Table of Contents Part 1: Validation of Computerized Systems Recent Changes in Regulations and Regulatory Guidance Instrument Qualification, Computerized System Validation and Method Validation Regulatory Requirements for Computerized System Validation Computerized System Validation Writing the User Requirements Specification (URS) Auditing the System Supplier Installation Qualification and Operational Qualification (IQ and OQ) Performance Qualification (PQ) or End User Testing Part 2: Method Validation Measurement Errors and Uncertainty of Measurement Validation of Analytical Procedures and Methods Interlaboratory Studies in Thermal Analysis Method Development Through to SOP Practical Examples Appendix 1: 21 CFR Part 11 and EU GMP Annex 11 Appendix 2: Basic Statistics Appendix 3: Standard Test Methods for Thermal Analysis

Book SynopsisThis practical introductory guide to injection molding simulation is aimed at both practicing engineers and students. It will help the reader to innovate and improve part design and molding processes, essential for efficient manufacturing.A user-friendly, case-study-based approach is applied, enhanced by many illustrations in full color. The book is conceptually divided into three parts:Chapters 1–5 introduce the fundamentals of injection molding, focusing the factors governing molding quality and how molding simulation methodology is developed. As they are essential to molding quality, the rheological, thermodynamic, thermal, mechanical, kinetic properties of plastics are fully elaborated in this part, as well as curing kinetics for thermoset plastics.Chapters 6–11 introduce CAE verification of design, a valuable tool for both part and mold designers toward avoiding molding problems in the design stage and to solve issues encountered in injection molding. This part covers design guidelines of part, gating, runner, and cooling channel systems. Temperature control in hot runner systems, prediction and control of warpage, and fiber orientation are also discussed.Chapters 12–17 introduce research and development in innovative molding, illustrating how CAE is applied to advanced molding techniques, including co-/bi-Injection molding, gas-/water-assisted injection molding, foam injection molding, powder injection molding, resin transfer molding, and integrated circuit packaging.The authors come from the creative simulation team at CoreTech System (Moldex3D), winner of the PPS James L. White Innovation Award 2015. Several CAE case study exercises for execution in the Moldex3D software are included to allow readers to practice what they have learned and test their understanding.In the 2nd edition, the concept of Cyber-Physical Systems (CPS) in injection molding is introduced. In order to integrate molding simulation and injection machines, the workflow of machine response characterization is illustrated. By taking into account the real-world machine response, users can more accurately reflect the real-world manufacturing conditions in simulations. The optimized processing conditions obtained from the simulation can then be directly applied on the shop floor, bridging the gap between simulation and manufacturing. In addition, a new flow-fiber coupling model, i.e., the informed-isotropic (IISO) viscosity developed by Dr. Favaloro and Prof. Pipes of Purdue University, to simulate the anisotropic flow for fiber-reinforced thermoplastics is introduced. The IISO coupling is available to simulate some peculiar, irregular filling patterns for fiber-reinforced melts at high fiber concentrations: the free surface advances faster along the side cavity walls.

Book SynopsisThis book creates a new perspective on the design of plastic parts. In many books there is a strong focus on the material, the material properties, and the calculation or dimensioning. What is often not taken into account is that very many plastic components only have to withstand low loads; in very many applications, the focus is on the actual design. This requires a good understanding of the injection molds that must be built to produce the plastic components. Depending on the design of the injection molded component, these molds become more complex and more prone to failure during production.The complex process of manufacturing a plastic part becomes holistically understandable as a link is created between the molder, the mold maker, and the part designer. The focus is on injection molds and therefore on thermoplastics.Everything that is necessary for the design and manufacture of an injection molded component is presented in a simple, extremely practical manner and limited to the essentials. Many descriptive pictures as well as examples based on the demonstration component ""Polyman"" facilitate the understanding enormously.

Book SynopsisSince their discovery in 1977, the evolution of conducting polymers has revolutionized modern science and technology. These polymers enjoy a special status in the area of materials science yet they are not as popular among young readers or common people when compared to other materials like metals, paper, plastics, rubber, textiles, ceramics and composites like concrete. Most importantly, much of the available literature in the form of papers, specific review articles and books is targeted either at advanced readers (scientists / technologists / engineers / senior academicians) or for those who are already familiar with the topic (doctoral / postdoctoral scholars). For a beginner or even school / college students, such compilations are bit difficult to access / digest. In fact, they need proper introduction to the topic of conducting polymers including their discovery, preparation, properties, applications and societal impact, using suitable examples and already

Book SynopsisThe Mold-Making Handbook has proven to be an essential resource for the plastics engineer who handles the design and construction of tools for different processing methods, from injection molding and blow molding, to prototyping tools, including their computer-aided design.The present edition has been completely updated with new chapters including micro injection molds, molds for the rubber industry, and rapid prototyping. Separate sections describe the tool materials and various manufacturing and processing methods. Each chapter is self-contained; the proposed synergistic effect is achieved especially when the reader not only reads »his« chapter, but is willing to »look outside the box« of his own specialist field.This handbook is for both the reader who is looking for an introduction to a key area of plastics processing as well as the pronounced specialist to enable quick reading into related technical areas. Written by experts from the industry, the book captures the current state of the technique. The Mold-Making Handbook will prove extremely useful for engineers, designers, processors, technical salesmen, and students interested in all aspects of mold construction.Table of Contents Molds for Various Processing Methods Mold Design Materials for Tool Making Manufacturing and Machining Methods Ordering and Operation of Molds.

Book SynopsisThree-dimensional molded interconnect devices (MIDs) enable mechanical, electronic, optical, thermal and fluidic functions to be integrated into injection-molded components. Function integration on this scale goes hand in hand with a high level of geometrical design freedom and opportunities for miniaturization, plus the associated reduction in weight and savings on product costs. MIDs are made primarily of recyclable thermoplastics, so they are more environmentally compatible than alternatives produced using other available technologies.MIDs are used in virtually every sector of electronics. The many standard applications for MIDs in the automotive industry in particular also drive for further development and research into MID technology. The significance of MID technology is also increasing in medical engineering, IT and telecommunications and in industrial automation, with numerous applications now successfully implemented in all these various fields.This book offers a comprehensive insight into the state of the art in 3D-MID technology along the entire process chain. Individual chapters, moreover, deal with systematics of targeted development of MID parts and explore, with a dozen and more successful series-production applications as examples, the widely diverse fields of application for MID technology.
