Things to know about Metal Manufacturing
Metal is a solid material that is hard, shiny, malleable, and ductile. It has good electrical and thermal conductivity (e.g. iron, gold, silver, Aluminium, and alloys such as steel).
Metal manufacturing occupies an important position in our day-to-day lives. Metal manufacturing has the following components:
1. Casting:
In this step, molten metal is poured into a mold cavity. The metal as a result starts to resemble the shape of the cavity. Casting may be of two types:
Expendable Mold Casting: In this sort of casting, the mold must be destroyed in order to remove the part.
Permanent Mold Casting: In this form of casting the mold is cut out of a ductile material & can be used repeatedly.
Powder Metallurgy: A metal powder is compacted into the shape desired. It is then heated to develop a bond between the particles.
2. Deformation Process
These processes include metal forming & sheet metalworking procedures. These processes use plastic deformation. The deformation Process may be divided into two types
A. Bulk Processes: These processes are characterized by big deformations & sharp changes. The surface area to volume ratio is relatively small. Bulk Processes include rolling, forging, extrusion, wire & bar drawing.
B. Sheet Metalworking: These processes are performed on metal sheets. Punch & die are used to form the workpiece. Bending, drawing & shearing are some of the types of sheet metalworking Processes.
3. Material Removal Processes:
These processes remove extra material from the workpiece in order to achieve the desired shape & size. The key components of these processes are as follows:
1. Machining Operations: These are cutting-oriented operations. They use cutting tools that are harder than the component metal. Turning, milling, shaping, planing, broaching & sawing are some of the steps included.
2. Abrasive Machining: Abrasive Particles remove materials in this kind of method. Grinding & honing are included in this category.
3. Non-traditional Processes: These processes (like lasers, electron beams, chemical erosion & electrochemical energy) disobey the convention (i.e. traditional cutting & grinding tools).
4. Joining & Assembly Processes: In these processes, multiple parts are connected in a permanent or semi-permanent fashion to form a new entity.
