Open Die Forging Vs Closed Die Forging – Processes and Applications

Forging is a manufacturing process in which a metal part is formed by pressing, shaping and welding the components together. In some cases, forging can be used to make tools or other objects out of metal.

Forging is a process of shaping metal by heating it and then pressing it into shape with the use of dies. The metal is heated to a high temperature and then fed into the die cavity. The metal cools as it goes through the die and hardens as it expands against the inside wall of the die cavity. 

Open die forging is a process of hot forging that uses open molds and dies to produce parts with complex geometries. The design and manufacture of these components involves the use of computer aided design, and machining technology. Open die forge is usually used for producing large heavy components with complex shapes. A forging company in India can help you with all your needs if you want to make your own products, from design to manufacturing to distribution.

Open Die Forging Process:

The basic principle behind open die forging is that it uses an open mold or form to shape the component while it is in a molten state through pressing and forming. The molten material is fed into a press which compresses it under pressure against the mold wall, causing it to flow into the cavity formed by the mold surface. The material flows around interior contours of the mold and solidifies as it cools down in contact with cold metal surfaces (mold surface), thus producing complex shapes.

Open die forging can be done on horizontal or vertical presses depending on the needs of the company. The process involves inserting the blank of metal inside the die, which forces it against a series of hammers that have been placed in precise positions in order to apply pressure to certain areas of the blank while leaving other areas untouched. The result is a highly accurate final product that has an excellent surface finish and exceptional dimensional stability.

Open die forging can be produced using either natural or artificial cores depending on their applications. Natural cores are made using solidified natural materials such as aluminum alloys and copper alloys whereas artificial cores are made from synthetic materials such as plastic compounds, stainless steel alloys, etc.

The advantages of open die forging over closed die forging include:

• Reduced cost and material consumption due to fewer closing operations.
• Less skilled labor required (i.e., less supervision and quality control tasks).
• Ability for operators to see into process and make adjustments quickly without having to shut down production lines.

Closed Die Forging Process:

Closed die forging is a process that uses a piston, which is pressed against a blank with a die. The blank is heated to increase its hardness, and the heated blank is then pressed into a die. The blank becomes harder on heating but retains its shape when cooled. This allows for the forging of high-strength parts with little distortion or deformation.

The closed die forging process is used to form parts that require a close fit between the die and part. Closed Die Forging is one of the most common processes for producing parts for a wide variety of applications, including automotive parts, machine tools, medical devices, and many others.

The closed die forging process has several advantages over open die forging:

• It can be used to produce parts that are not strong enough for open die forging by adding elements such as fiber reinforcement.
• It produces more consistent results than open die forging due to the heat treatment and pressure differential between the blank and die.
• It allows for metallurgical control over heat treatment and processing steps in order to produce specific properties in the final product (e.g., strength).
