1.Definition of Forging Parts/Forging Big Parts/Die Forging

Youlin® Forging Parts/Forging Big Parts/Die Forging is the most common option for metal deformation, which has two popular processes:
Open Forging Parts/Forging Big Parts/Die Forging, is also called free forging. In open Forging Parts/Forging Big Parts/Die Forging, the billet is placed between multiple dies that do not enclose the metal entirely. The dimensions will be changed by hammering and stamping the metal through a series of movement until the final dimensions are achieved. Open Forging Parts/Forging Big Parts/Die Forging is widely used for the products in small quantity that are simple, rather than complex, such as discs, rings, sleeves, cylinders and shafts. Another benefit of open Forging Parts/Forging Big Parts/Die Forging is that the fatigue resistance and strength of products will be improved. Besides, voids could be effectively reduced after open Forging Parts/Forging Big Parts/Die Forging.

Closed Forging Parts/Forging Big Parts/Die Forging, is also referred to as impression Forging Parts/Forging Big Parts/Die Forging. It utilizes high pressure to compress the metal piece to fill an enclosed die impression for required shapes. For some special shapes, second forging operation is required to reach final shapes and dimensions. The type of material, tightness of tolerances, and need for heat treatment can determine the cost of a closed die forged part.

2.Differences between Open Forging Parts/Forging Big Parts/Die Forging and Closed Forging Parts/Forging Big Parts/Die Forging

The technique of both open Youlin® Forging Parts/Forging Big Parts/Die Forging and closed Forging Parts/Forging Big Parts/Die Forging is different. In general, for closed Forging Parts/Forging Big Parts/Die Forging, the molding dies are first precision machined and cost is high. The metal bars are then placed on between upper and lower dies and forged to any shapes needed. After closed Forging Parts/Forging Big Parts/Die Forging very less or no machining will be operated due to its high accuracy throughout the process. So closed Forging Parts/Forging Big Parts/Die Forging is also a net shape or near net shape process.
For open Forging Parts/Forging Big Parts/Die Forging, enormous compressive forces are imposed by the continuous strike of a forging hammer to deform the metal billets. Unlike closed Forging Parts/Forging Big Parts/Die Forging, dies of open Forging Parts/Forging Big Parts/Die Forging is very simple. And secondly machining operation is always carried out.

3.Advantages & Disadvantages of Open Forging Parts/Forging Big Parts/Die Forging and Closed Forging Parts/Forging Big Parts/Die Forging

1.Definition of Forging Parts/Forging Big Parts/Die Forging

Closed Forging Parts/Forging Big Parts/Die Forging and open die casting are the most common used forging methods for steel parts. Forging is popular because of its improved internal grain structure and can produce stronger and tougher products.

In Open Forging Parts/Forging Big Parts/Die Forging, a rough or precision machining is normally further required after the open Forging Parts/Forging Big Parts/Die Forging process as imprecise dimensions are achieved by hammering. Thus, open Forging Parts/Forging Big Parts/Die Forging is more suitable for large parts in a number of tons. Generally, the products in forging method include forged long shafts, forged rollers, and forged cylinders, which are mostly used for the application of railway and aircraft industry.
However, closed Forging Parts/Forging Big Parts/Die Forging is preferred for small critical parts with safety consideration because of its high precision. It is highly used to produce small products like forged fittings, forged lifting & rigging hardware, forged automotive parts, etc. Oilfield, automotive, forestry & agriculture, and mining are some of the industries that rely on closed Forging Parts/Forging Big Parts/Die Forging technique.

5. FAQ

Which is the disadvantage of open Forging Parts/Forging Big Parts/Die Forging?
A: Open-Forging Parts/Forging Big Parts/Die Forging is not recommended for complex shapes, and often requires precision machining to complete the process since the dimensions produced by hammering during the open die process can be imprecise.

Q: What can be made from open Forging Parts/Forging Big Parts/Die Forging?
A: The process of open Forging Parts/Forging Big Parts/Die Forging typically produces round, rectangular, square, and hexagonal bars, beams, as well as other basic shapes. Common products formed include hubs, spindles, step shafts, mandrel, metal shells, pierced blanks, and simple pancakes forgings.

Q: What are the limitations of open Forging Parts/Forging Big Parts/Die Forging?
A: ▷ Not suitable for forming intricate, precision parts or other close-tolerance applications.
    ▷ Machining is often required to complete open-Forging Parts/Forging Big Parts/Die Forgings.
    ▷ Process doesn't always produce consistent results or desired features.
