Closed Die Forging: Steps Of Closed Die Hot Forging

Closed die hot forging is a plastic deformation process for small and medium metal components. As the name suggests, the material being formed is forced to flow in a closed shape die. One of the benefits of this form of hot forging is that open die forging can produce more complex shapes. But what the process of closed die hot forging? Here are the steps you need to follow.

1. Mold Design and Making

The first step of closed die hot forging is designing and making the mold. Depending on the size and shape of the product you want to hot forge, you need a mold. Designing the mold is the trickiest part. But with modern machining technology, you only need software to design and make the mold. What you need is computer-aided design (CAD) technology for designing and making the mold.

2. Choose steel

Closed forging is mostly used for the hot forging of steel material. So, you need to select the steel specification to ensure that you have the suitable material. The most common types of steel used include stainless steel, carbon steel, and alloy steel. The importance of choosing steel is to get the facts such as the forging temperature and press force.

3. Steel Heating

With the correct steel, the next thing you need to get right is steel; the nest step is heating it. This is very crucial because you need to observe the forging temperature. Make sure that the steel is heated to the desired temperature. Depending on the intensity of the heat, the process usually takes about 10 to 15 minutes. Once it is properly heated and in molten form, preform it to fit in the mold.

4. Forging The steel

With the mold ready and the steel heated and preformed, it is time to hot forge. The closed die hot forging includes placing the hot steel in the mold and placing another mold on top to enclose. The molds are applied pressure using hydraulic hot forging press for the billet to take molds’ shape and size. That’s how hot forged steel parts are made using hot forged.

5. Heat Treatment and Finishing

With the steel forged parts made, they need to be heated treated to regain fine grains. That’s how strength and hardness are achieved. Finally, do some finish work for a perfect shape and size.

There is doubt that the hydraulic press is some of the widely used machines in the industrial world. Their vast application in the manufacturing industry is because of the many benefits they to the manufacturers. But what the main benefits of using a hydraulic press?

Well, there are many benefits that comes with using these machines, and these are just some of them:

Creating Intricate Shapes

One of the biggest that comes with using the hydraulic press is the creation of intricate shapes. These machines work with molds and die that enables them to produce a variety of shapes. In fact, if you want to create 3D products, hydraulic press machines can do very well in forging. This is one of the reasons why these machines are growing popular in the industrial world.

Economical On Materials

The other benefit of using the hydraulic press is that they are low economic on material usage. When used in various areas, including forging, it has been found that these machines have very little material wastage. They produce near-net shapes, and that’s how they are able to reduce material wastage. So, the overall cost of production is reduced.

Takes Less Space Compared To Mechanical Press

If you are planning to start a pressing plant, then a hydraulic press would be the ideal press machine to invest in. One of the reasons why they are the best is that they take less space. So, if you are renting space, you will be spending less money on rentals with a hydraulic press.

Quiet Operations

Another advantage of a hydraulic press is quiet operations. From their designs, a majority of these machines do not have mechanical parts. Therefore, there are very few instances where machines’ parts are causing friction. That’s how these machines are able to operate with minimal or no noise at all. This means you can work with them even hear people, and they will not cause any disturbances.

Better Flexibility

When it comes to flexibility in use and production, you will like that hydraulic machines offer better flexibility. These machines can be used to form anything, and all you need is to change the does and maybe the punch to produce the part you want.
