Drop-bottom cupola furnace Personal protective equipment to shield from radiant heat and molten splashes. Cupola furnaces were built in China as early as the Warring States period (403–221 BC), [4] although Donald Wagner writes that some iron ore melted in the blast furnace may have been cast directly into molds.
NPTEL is the largest e-repository in the world of courses in engineering, basic sciences and selected humanities and management subjects. [1] The platform and materials have been jointly developed by Indian Institutes of Technology (IITs) and Indian Institute of Science. [2] The initiative is funded by the central Ministry of Education. The ...
Sintering or frittage is the process of compacting and forming a solid mass of material by pressure [1] or heat [2] without melting it to the point of liquefaction. Sintering happens as part of a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms/molecules in the sintered material diffuse across the ...
Apply investment materials: The ceramic mould, known as the investment, is produced by repeating a series of steps—coating, stuccoing, and hardening—until a desired thickness is achieved. Coating involves dipping a pattern cluster into a slurry of fine refractory material and then draining to create a uniform surface coating.
Material requirements planning (MRP) is a production planning, scheduling, and inventory control system used to manage manufacturing processes. Most MRP systems are software-based, but it is possible to conduct MRP by hand as well. An MRP system is intended to simultaneously meet three objectives:
MBOM is a type of bill of materials (BOM). Unlike engineering bill of materials (EBOM), which is organized with regards to how the product is designed, the MBOM is focused on the parts that are needed to manufacture a product. In addition to the parts list in an EBOM, the MBOM also includes information about how the parts relate to each other.
Solder is a metallic material that is used to connect metal workpieces. The choice of specific solder alloys depends on their melting point, chemical reactivity, mechanical properties, toxicity, and other properties. Hence a wide range of solder alloys exist, and only major ones are listed below.
Heat treating (or heat treatment) is a group of industrial, thermal and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical. Heat treatments are also used in the manufacture of many other materials, such as glass. Heat treatment involves the use of ...
