The main function of the
Metal Fabrication Industry is to produce component metal parts that will fit in along with other parts, to form a larger machinery. In this way the Metal Fabrication Industry proves to be an essential section of the entire global metal industry as it produces minute spare parts of larger heavy machinery and equipments, which cannot be manufactured simultaneously with the manufacturing of the heavy machines.
The Processes involved in the manufacture of tools and machine parts in the Metal Fabrication Industry.
The construction of fine and minute machine parts involve several procedures which require a lot of concentration on the part of the person involved in it . They are therefore not carried out by the large scale metal industries and are in fact manufactured in the small scale Metal Fabrication Industry. The production of minute machine parts (most commonly, smaller constituents of a heavy machine) include the processes as given below :
- Cutting
- Molding
- Finishing.
The metal sheets that are used in the Metal Fabrication Industry are at first cut into finer sections, in order to fit the size of the parts or the finished products, that are to be manufactured in the Metal Fabrication Industry. The metal sheets can be cut as per the following cutting methods :
- Shearing
- Electrical Discharge Machining (EDM)
- Abrasive cutting
- Laser cutting.
Then, these metal sheets which are already cut into requisite sizes are molded into definite shapes as well as sizes as per the requirements of the Metal Fabrication Industry. The Metal Fabrication Industry employs a number of methods to mold the cut metal sheets into definite shapes, which are as follows :
- Rolling
- Bending and forming
- Stamping
- Punching.
At the end of cutting and molding, the manufactured item is checked for rough edges which are smoothened by polishing with an abrasive.
At last the end product is either sold as an individual product or fitted with other parts to form a larger heavy machinery, and circulated for sales in the markets.
