Know the Different Types of Industrial Fabrication Processes in Kolkata

It might be a challenging task to believe that fabricated metal is all around us, but nonetheless, it is a fact. From the smallest structures like a safety pin to the largest of buildings are all a result of metal fabrication. The process basically involves manipulating metal in a way so that it can be shaped into whatever our need is. There are quite a few processes that are involved as far as fabrication is concerned. Discussed below are the processes that industrial fabrication in Kolkata entails.

Here are the Processes That Constitute to Industrial Fabrication

• Cutting

While there are quite a few types of modern technology that is used for the cutting process nowadays, the traditional method is to cut the metal using a saw. In addition to this classic form of getting the job done, the new methods that are used now are water-jets, plasma torches and lasers. Each of these methods can be used in the cutting process but they vary greatly as far as complexity and price are concerned, with some of the machinery costing quite a lot, sometimes in the tens of lakhs.

• Folding

Another process relevant to industrial fabrication is that of folding. Some parts of the metal need to be bent and this is done on most occasions with the use of a brake press. The press has certain dies that pinch the metal that results in creases being formed in it. This particular operation is reserved only for the specific cases because of the part’s movement and the shape of the die.

• Machining

In this process, the removal of the metal from a material is involved. Machining can be done with the use of a lathe, which entails the material rotating against a cutting tool, or in other cases, another type of cutting machine like a drill is put into use. If a drill is being used, the tool is rotated in different ways with the stationary piece in the other end. The motion range of the cutting tool is defined by the number of axes.

• Punching

This process involves the using of the die and punch. The former cuts the piece of metal out while also making a hole in it. The punch and die have to be of the similar size and shape as the hole. On some occasions, the main piece is kept and holes are punched in order to fasten, while on others, the removed portion is itself the product that is required. This product is known as the blanking.

• Others

In addition to the above processes, others that are used are shearing, stamping and welding. In the case of shearing, a long cut is made on a metal piece. Stamping is a similar process to punching, but the material is not cut as it is in punching. Welding is the process where two pieces are metal are joined together.

These are the processes involved in industrial fabrication. There are quite a few others but the ones listed above are the most common.
