Industry Specific Manufacturing Processes

 

·      What is Manufacturing Process?

Manufacturing is the processing of raw materials or parts into finished goods through the use of tools, human labor, machinery, and chemical processing. Large-scale manufacturing allows for the mass production of goods using assembly line processes and advanced technologies as core assets. Efficient manufacturing techniques enable manufacturers to take advantage of economies of scale, producing more units at a lower cost.

Manufacturing is a value-adding process allowing businesses to sell finished products at a higher cost over the value of the raw materials used. It is often reported on by the conference board, and well examined by economists.

                                            

·      Classification of Manufacturing Process

1.    Casting and Molding Process

2.    Machining Process

3.    Joining Process

4.    Shearing and Forming Process

 

 

·      Casting Process

Casting is a manufacturing process in which a liquid material is usually poured into a mold containing a cavity of the desired shape and then allowed to solidify. After solidification, the workpiece is removed from the mold for various finishing treatments or to be used as an end product that also defined as casting. 

Examples :-  Sand casting

                      Investment casting

                      Die casting

                      Low pressure casting.

                      Centrifugal casting.

                      Vacuum die casting.

 

 

·      Forming Process

Large set of manufacturing processes in which the material is deformed

plastically to take the shape of the die geometry. The tools used for such deformation are called die, punch etc. depending on the type of process.

Examples :-  Drop Forging

                      Press Forging

                      Upset Forging

                      Wire Forging

                      Rolling

 

·      Welding Process

Welding is a fabrication process whereby two or more parts are fused together by means of heat, pressure or both forming a join as the parts cool. Welding is usually used on metals and thermoplastics but can also be used on wood. The completed welded joint may be referred to as a weldment.

Examples :-  Gas Welding

                      Electric Arc Welding

                      Resistance Welding

                      Soldering

                      Brazing

 

·      Material Removal Process

Material removal process is a type of manufacturing process in which the final product is obtained by removing excess metal from the stock. The best example of a machining process is generating a cylindrical surface from a metal stock with the help of a lathe.

This is one of the most expensive manufacturing process among the four basic manufacturing processes i.e. forming, casting, fabrication and material removal.

Examples :-  Drilling

                      Milling

                      Grinding

                      Broaching

                      Turning
