We are pleased to now present this definitive foundry practice reference book in English after it has appeared in German for more than 70 years already. Specialised requirements worldwide demand liberal thinking and the confident application of new technologies. Ongoing technical training, familiarisation with new developments and studying current research results are key components of everyday working practices. The Pocket Guide Foundry is intended to provide appropriate information and offer inspiration in addition to supporting the development of technical contacts. It is not merely a helpful complement to vocational training, studies or continuing education, but also serves as a straightforward reference for practitioners and suppliers in the foundry industry, for design engineers, production engineers and readers with technical interests. Especially for young people who come into contact with the themes of "foundries and castings" from a wide variety of vocations and many different directions, the Pocket Guide Foundry serves as a starting point for a deeper technical understanding.
