    • Suhas Kulkarni
    • English
    The book introduces the reader to the concepts of Scientific Molding and Scientific Processing for Injection Molding, geared towards developing a robust, repeatable, and reproducible (3Rs) molding process. The effects of polymer morphology, thermal transitions, drying, and rheology on the injection molding process are explained in detail. The development of a robust molding process is broken down into two sections and is described as the Cosmetic Process and the Dimensional Process. Scientific molding procedures to establish a 3R process are provided. The concept of Design of Experiments (DOEs) for and in injection molding is explained, providing an insight into the cosmetic and dimensional process windows. A plan to release qualified molds into production with troubleshooting tips is also provided. Topics that impact a robust process such as the use of regrind, mold cooling, and venting are also described. Readers will be able to utilize the knowledge gained from the book in their day-to-day operations immediately. The third edition includes a completely new subchapter "Melt Preparation", as well as much additional, revised, and updated material throughout the book. The revisions are deeply informed by the authors long and ongoing experience as a trainer, result in improved ways to conduct a study, perform experiments, or explain a concept.

  • The Effect of Temperature and other Factors on Plastics and Elastomers

    • 4th Edition
    • April 4, 2023
    • Laurence W. McKeen
    • English
    The Effect of Temperature and Other Factors on the Properties of Plastics and Elastomers, Fourth Edition provides data on the wide spectrum of plastics and TPEs with special reference to thermal stability. The mechanical, physical and electrical properties of plastics and elastomers are described as a function of temperature and humidity to help with the design of lighter more cost-effective plastic parts to replace metal ones. In this new edition, expertly edited data makes it easy for readers to learn about the properties of plastic materials without having to search the general literature or depend on suppliers. Additional types of plastics are examined, and the latest data on material characteristics are provided. Complex details such as how the thermal prehistory can effect final mechanical properties, and how temperature scans reveal dynamic mechanical behavior are also examined to build a deeper understanding of the materials.

  • Extruder Processing

    Comparison of Single- and Twin-Screw Extruders for Optimal Solids Conveying, Melting, and Mixing
    • 1st Edition
    • January 27, 2023
    • Paul G. Andersen + 1 more
    • English
    Single-screw or twin-screw extruder? When the need to produce a homogenous 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 will aid the practitioner in comparing these two types of extrusion equipment relative to process requirements, and taking optimal decisions.

  • Injection Mold Design Engineering

    • 3rd Edition
    • November 1, 2022
    • David O. Kazmer
    • English
    Injection Mold Design Engineering provides a structured methodology and scientific basis for engineering injection molds. The topics are presented in a top-down manner, beginning with introductory definitions and the big picture before proceeding to layout and detailed design of molds. The book provides very pragmatic analysis with worked examples that can be readily adapted to real-world product design applications. It will help students and practitioners to understand the inner workings of injection molds and encourage them to think outside the box in developing innovative and highly functional mold designs. Injection molding continues to be a core plastics manufacturing process, but now has competition from additive manufacturing for certain applications, and environmental concerns are in the spotlight. The 3rd edition addresses these issues, in particular with a new chapter on mold manufacturing strategy to provide an overview of the most common machining and additive manufacturing processes with cost and time models to guide the manufacturing strategy; updated and simplified break-even cost models to assist in the mold layout design (number of cavities and type of mold) vs. 3D printing; a new section on environmental concerns include mold design for recycled resins; and updates to the International Tolerance standards, and the new technology and simulation sections.

  • Design of Injection Molded Plastic Parts

    • 1st Edition
    • July 15, 2022
    • Christoph Jaroschek
    • English
    Design of Injection Molded Plastic Parts 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 a demonstration component aid understanding throughout the book.
