Raw metals aren’t of much importance. For them to be useful, the manufacturer has to process them. This process can alter the physical structure of the metal, and sometimes, even the visual structure. This is what forging processes do. They help to make these alterations so that the metal can become relevant to society.
For those who don’t know what forging processes are, here is a brief description. A forging process is a manufacturing process whereby metal is shaped using several compressive forces. These forces are applied using a hammer or a die. There are several types of forging processes, but in this article, we will focus on the pros and cons.
Before we proceed, understand that there are different ranges of temperatures used for different types of forging processes. This is where the hot and cold forging processes come in, and there are subtypes of forging processes under these two broad categories.
Different types of metals go through the forging process, but each one is handled in a specific way. If you use a particular forging process for another metal, it will render it useless. This is why there are different types and subtypes of forging processes.
Without further ado, let’s delve into the business of the day.
Advantages of forging processes
There are several benefits of forging processes
1. Strong machined parts:
Manufacturers have to decide which type of process they would use on their metal. It’s often either between casting and forging.
But the truth is, if you compare products gotten from forging processes to products gotten from casting, you’d see the obvious difference. Forged products are often stronger. This is because the internal grain structure of the metal is realigned to conform with the intended shape or configuration. Therefore, the strength of the material is improved.
2. It’s more affordable
A lot of manufacturers go for forging processes because it’s more cost-effective or affordable, compared to fabrication methods or metal casting. This is because there are fewer requirements.
Now, due to the complicated equipment used in the forging process, a lot of people think that they are so expensive. Sorry to burst your bubble, but they are actually sold at affordable prices, especially to people who use them for commercial purposes. At the end of the day, you pay less money for all parts of the process.
3. After-forging machining
It’s easier for metals to undergo machining after forging than after other metal-work processes. Why? This is because forging leads to fewer cracks and little to no voids. The porosity rate is also very low. When the material is forged, the machining process will be very accurate.
Disadvantages of forging processes
A lot of manufacturers, especially low-budget ones, don’t go for forging processes initially because it’s capital-intensive. The machines and tools you will require at the beginning might be way above your budget. But once you can get money to buy these tools, you will have a smooth work experience.
Furthermore, forging can’t be handled by any person. It can only be done by well-trained technicians and monitored by them too. You may also consider the negative environmental impact it may have due to the noise and vibrations it produces.
