Book Synopsis Physical Foam Injection Molding by : Hartmut Traut
Download or read book Physical Foam Injection Molding written by Hartmut Traut and published by Carl Hanser Verlag GmbH Co KG. This book was released on 2024-05-06 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than half of all injection molded plastic parts can be produced more cost-effectively and with better tolerances using foam injection molding compared to traditional compact injection molding. For the part designer, the focus is on the functionality of the molded part, not on the plastic-compatible design, which is precisely what compact injection molding requires. This book describes the necessary fundamentals of physical foam injection molding, clearly illustrated by means of detailed, industrially proven examples to show the technology’s potential. Machine and mold technology are also explained in detail, and polymers suitable for the process are discussed. The focus is always on the question of whether the potential of physical foam injection molding has already been exhausted or whether it is emerging as a second standard process alongside compact injection molding. The experienced authors make it possible to look beyond the end of one’s nose. The reader can see which plastic parts can be converted from compact to foam injection molding, and is encouraged to rethink the part design. With this book, specialists are able to examine an application for their own company and analyze it with regard to its economic implementation. However, the book also shows the clear limitations of this technology. Content: Foam Injection Molding and its Different Process Variants Definition and Characteristics of Physical Foam Injection Molding Design Guidelines for Foamed Components Polymers for Foam Injection Molding Process Simulation Mechanical Fundamentals of the Foam Injection Molding System Mold Technology Application Examples: Automotive/Household/Packaging/Medical

Available in PDF, EPUB and Kindle. Book excerpt: Polylactide Foams: Fundamentals, Manufacturing, and Applications provides an introduction to the fundamental science behind plastic foams, polylactic acid) and polylactide foaming, giving designers tactics to replace traditional resins with sustainable and biodegradable materials. The book then delves deeper into the technology behind PLA foaming, such as PLA/gas mixture characteristics, solubility, interfacial tension behaviors and crystallization kinetics of various types of PLA and their compounds. The foaming behaviors and mechanisms of various types of PLA and PLA compounds are extensively analyzed and discussed through different manufacturing technologies, namely extrusion foaming, foam injection molding and bead foaming. Interest in Poly(lactic acid) and PLA foams is extremely high – particularly as a potential replacement for styrenic resins – and the price of PLA resin is lower than ever before. This biopolymer has significant potential to improve the sustainability of the plastics industry. Polylactide Foams have a range of potential applications, such as in construction, packaging, insulation, biomedical scaffolds, and others. However, processing and performance of PLA are not at the same level as other non-biodegradable resins. - Introduces the concepts behind foaming, poly(lactic acid) and PLA foaming - Supports further research and development in PLA foams by covering the state-of-the-art in different manufacturing and processing methods - Provides practical guidance for materials scientists and engineers in industry looking to replace traditional polymer resins with a sustainable, biodegradable alternative

Book Synopsis Investigation of Foaming Behaviors in Injection Molding Using Mold Pressure Profile by : John Won S. Lee
Download or read book Investigation of Foaming Behaviors in Injection Molding Using Mold Pressure Profile written by John Won S. Lee and published by . This book was released on 2009 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is intended to improve the understanding of foaming behaviors in various foam injection molding processes: structural foam molding, gas counter pressure molding, and gas counter pressure with mold opening. The foaming behavior in foam injection molding is different from foam extrusion in two ways. First, foaming occurs in a confined volume, which consists of a mold, whereas, it occurs in an open environment in foam extrusion. And second, while the foaming behavior in foam extrusion does not change with time once the steady state is reached, foam injection molding is on the other hand, time-dependent. These differences made it very challenging to study the foaming behaviors in foam injection molding. In this thesis, experiments were first conducted in foam extrusion to understand the effects of processing and material parameters on cell nucleation and growth behaviors. Subsequently, the knowledge obtained from the foam extrusion experiments was transferred to the foam injection molding process and the fundamental foaming mechanisms in foam injection molding were developed by conducting extensive experiments. Four processing parameters were mainly studied in this thesis: injection speed, void fraction setting (i.e., shot size), nitrogen content, and gate resistance. The experimental results revealed that the mold pressure profile during the foam injection molding process governed its foaming behaviors. Furthermore, by analyzing the mold pressure profile during the structural foam molding, it was possible to predict the achievable cell density in structural foam molding based on the foam extrusion results. When the gas counter pressure was employed, the analysis of the foaming behavior was relatively easier since the cell nucleation did not occur during the injection stage. However, the cell density that was achieved by using the gas counter pressure was generally lower than that obtained in structural foam molding due to the lower pressure drop rate caused by the use of the gas counter pressure. It was also discovered that the use of mold opening in combination with the gas counter pressure was very effective when uniform cell structure with a high void fraction was desired in addition to class-A surface quality.
