Book Description :

Earlier work on the ultrasonic extrusion of lead and aluminum has been extended to the cold extrusion of plasticized ceramic compositions, resulting in significant improvements in increased extrusion rate (more than 100-fold), decreased extrusion pressure (2 to 10 fold), and in extruded specimen properties. It has also been found possible to extrude materials which are normally nonextrudable because of their low plasticizer or water content. Fused, ground alumina could be ultrasonically extruded with 15% less water than the minimum content without ultrasonics, and only 40 to 60% of that used in normal commercial practice. Significant improvement in the strength of as-extruded shapes, as well as reduced shrinkage and deformation in drying and firing, resulted. Compositions normally using 3 w/o ammonium alginate as a plasticizer can be extruded with 0.2 w/o plastizer when ultrasonically activated. It has been postulated that the ultrasonic effects observed are derived from reduction of surface friction, shear thinning of the thixotropic systems, particle orientation, surface-film rupture, and wetting phenomena. As-extruded specimen improvement was evidenced by a smoother surface and freedom from cracks, tearing, and peeling. When steel dies were used, abrasion of the die surface sometimes caused a superficially discolored surface in nonultrasonic extrusions. The comparable ultrasonic extrusions showed little or no discoloration as the ultrasonic power level was increased. Ultrasonically extruded specimens which were fired in the same kiln loading as their corresponding controls show small but consistent increases in fired density. Water absorption was approximately 75% of the control. The highest moduli of rupture in the fired specimens were found in the ultrasonic specimens even though these required only 25% of the extrusion pressure of the controls.

Book Description :

The economic importance of extrusion has increased markedly in the years, primarily because of spectacular technological advances that have drawn on both practical experience and fundamental research and that have elaborated on extrusion processes, tooling, and metal flow. Expert information of diffusion is itself diffuse, spread over an array of international technical journals and proprietary reports and presented in several languages. This book, written by acknowledged authorities and originally published in the German language, succeeds in providing a comprehensive and detailed treatment of all aspects of extrusion, with special emphasis on the latest advanced technology. Among the extruded metals covered are aluminium, lead, tin, magnesium, zinc, copper. titanium, zirconium, beryllium, uranium, nickel, and steel. Processes discussed include direct and indirect extrusion, cable sheathing by extrusion, hydrostatic extrusion, cladding by extrusion and special technology for extruding various metals. Also discussed are stresses in extrusion, economic aspects, and future developments.

Book Description :

Frank Handle ̈ 1.1 What to Expect For some time now, I have been toying around with the idea of writing a book about “Ceramic Extrusion”, because to my amazement I have been unable to locate a single existing, comprehensive rundown on the subject – much in contrast to, say, plastic extrusion and despite the fact that there are some outstanding contributions to be found about certain, individual topics, such as those in textbooks by Reed [1], Krause [2], Bender/Handle ̈ [3] et al. By way of analogy to Woody Allen’s wonderfully ironic movie entitled “Eve- thing You Always Wanted to Know about Sex”, I originally intended to call this book “Everything You Always Wanted to Know about Ceramic Extrusion”, but - ter giving it some extra thought, I eventually decided on a somewhat soberer title. Nevertheless, my companion writers and I have done our best – considering our target group and their motives – not to revert to the kind of jargon that people use when they think the less understandable it sounds, the more scienti c it appears. This book addresses all those who are looking for a lot or a little general or selective information about ceramic extrusion and its sundry aspects. We realize that most of our readers will not be perusing this book just for fun or out of intellectual curiosity, but because they hope to get some use out of it for their own endeavours.
