Revision of The Extruder Book published in 2001. New images, updated materials.If you have an extruder and aren't sure what to do with it, Daryl's comprehensive book updates his best-selling first edition. You'll discover tips for setting up your studio, supplies you'll need to make extruding easier, and accessories that will help you with more complicated extrusions. Your extruder set-up can be as sophisticated as any pros with less effort than you think.Since his first edition, Daryl has expanded his offering of projects and you'll discover sixteen great demonstrations which will increase your confidence and challenge your skills. From using simple dies to constructing projects from multiple-part dies, Daryl carefully leads you step-by-step through projects that run the gamut of complexity. As you master each process, your imagination will inspire even more ideas to take on.If you don't already have an extruder, don't worry. Daryl describes what's on the market today from major manufacturers, but he also includes plans on how to make your own extruder from parts you can gather at a local home center. But the essence of an extruder is the die and here is where Daryl showcases his expertise. From altering stock dies to creating complex multi-part dies, you'll find instructions for making unique dies unlike any you can buy on the market.To illustrate just how versatile the extruder is, Daryl showcases the work of dozens of potters and artists using the extruder in their work. You'll be inspired by the creativity and you'll see that your extruder is capable of much more than just making test tiles or strap handles.
Co-rotating screws and/or extruders are used in many branches of industry for producing, preparing and/or processing highly viscous materials. They find a wide variety of applications especially in the plastics, rubber and food industries. This book provides basic engineering knowledge regarding twin-screw machines; it lists the most important machine-technical requirements and provides examples based on actual practice. Better understanding of the processes is emphasized as this is a prerequisite for optimizing twin-screw designs and operating them efficiently.
Thoroughly updated since the publication of the first edition, with new chapters on die design for operators, solids conveying and melting and twin-screw extruders, this book bridges the gap between theoretical studies and the practical experience of the processor in the extrusion of thermoplastic polymers and rubbers. Theoretical discussions generally give little attention to practical considerations, such as the conflict between productivity and product quality. Here however the authors give a clear representation of the physical mechanisms on which so much of the polymer processing industry depends, followed by guidance on operational strategies and the likely effects in terms of output, quality, uniformity and stability. Practical information is given on start-up trials, scale-up, product changing, dismantling and cleaning. Supported by over 40 tables and 176 figures, Extruder Principlesand Operation will provide commercial processors with a logical background based on theory and experience, which will help them to obtain the best performance from their equipment, to recognize its limitations and to face new problems with confidence.
