PRESSING CHALLENGING PARTS ON A PRODUCTION SCALE BY USING DIE WALL LUBRICATION TECHNOLOGY

摘要

Recent developments have made the use of the die wall technology, an efficient and reliable way of pressing parts, of complex shapes and high aspect ratio, even at high densities. The goal of this paper is to review recent improvements and concerns of the industry regarding this technology to press complex parts. The impact of using this technology on the properties of typical P/M parts, such as green density, density gradients, and ejection behavior is discussed.
