What is Forging process?
Forging as a manufacturing process that involve shaping of metal using localized compressive forces like hammer usually power hammer or a die. it can also be defined as the process of heating, deforming and finishing a piece of metal by forcing them into desired shape.
In my previous articles, I have enlighten on Different Types of Forging process and Different types of forging operations. Today articles is on what is forging process?, its advantages and disadvantages.
Forging shapes are obtained by the force and of a falling ram upon an anvil or by a die press enclosing piece of metal and squeeze-forming the parts. They are classified according to the temperature at which it is performed: cold, warm and hot forging. it has been done by smith for some time now in producing items like, hardware, hand tools, edged weapons, jewelry and kitchenware, and they are widely used in mechanisms and machines whenever a component requires high strength. they also required further processing, such as machining to obtain finished object. it also offer better response to heat treatment and can be nearly any shape, it reduces the need of joining multiple places which can improve the overall strength of the objects as welding and other joining methods are not involve.
Advantages and Disadvantages of forging
A lot of advantages as it is applicable in many areas in manufacturing world. It also has little disadvantages than can be overlook because it offers superior quality over other manufacturing process. Some advantages are:
- It products are strong.
- It is more reliable and less costly.
- It response better to heat treatment.
- It offers more consistent and better metallurgical properties.
- It sometimes requires secondary operation.
- It is used to make variety of shapes.
- It design is flexible.
- It offers broad size range of products.
Some disadvantages of forging are:
- It is difficult to perform secondary operation in hot forging.
- Capital cost is more in forging work.
- Very high man and materials safety procedures need to be followed.
As mentioned earlier, forging process gives quality products but there are still some defects that may occurs, it includes, unfilled sections, cold shut, scale pitta, die shift, flakes, improper grain flow.
