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.
Most books on plastics machinery include a preamble on the origin of such equipment, and some even discuss the origin of plastic itself, dating back to the early 1900s and such men as Leo Baekeland - the real founder of synthetic plastics. There seems therefore, little pur pose in reiterating what has been said before and going over the same ground so adequately covered in a number of books as well as the trade press. We are indebted to the author of this excellent treatise on twin-screw extruders for getting right down to the business at hand. The author makes mention of two pioneers - Roberto Colombo and Carlo Pasquetti - who were the first to develop twin-screw ex truders. It was my good fortune to follow the work of these pioneers, and, interestingly enough, the principles were so good that their work continues to be relevant even to the advanced and more sophisticated models so well defmed in this book.
