The collection of Engineering metallurgy comprises processing of iron in engineering works by casting and forming. The foundry collection includes mainly exhibits documenting technological development of the field. It contains steel and iron castings, foundry tools, models, forms and their parts, foundry furnaces and foundry equipment. They document the technology of casting into sand forms, lost wax process, shell casting and other production techniqes over the time period from the 18th century till present times. Historical foundry process is documented by a large model of foundry acquired into the Museum collections in 1914. Artistic casting has been included under the input item Decorative cast ironwork. The collection of forming field contains mainly drop forgings from the 1st and 2nd halves of 20th century. In many cases the whole technological process is depicted starting from incoming semi-product via respective intermediate stages to finished product. These include, for instance, tools and components of car and aviation industries. Engineering equipment is documented by precise models of forging machine hammers and presses manufactured and used for education at the Prague Technical University in the 19th century as well as by perfect models of the most up-to-date forging machines of the firm ZDAS from the 70s and 80s of 20th century. The tools and products of manual smithery are included under the input item Smith and locksmith crafts.
