Forging processes are essential in the automotive industry for producing high-quality, durable parts.
There are several types of forging processes used in this industry, each with its own advantages and applications.
4 Key Methods Explained
1. Impression Die Forging (Closed Die)
Impression die forging, also known as closed die forging, uses multiple dies that completely enclose the part.
This process allows for the formation of complex shapes at higher volumes.
Closed die forging results in better accuracy of the finished part.
However, the costs for closed dies are typically higher than open dies.
2. Open Die Forging
Open die forging uses multiple dies that do not fully enclose the part.
This process is ideal for simple shapes at lower volumes.
Secondary machining is usually required with open die forging.
3. Cold Forging
Cold forging is a process where metal is formed at room temperature or below its recrystallization temperature.
It is typically used for producing small and complex parts with high dimensional accuracy and surface finish.
4. Seamless Rolled Ring Forging
Seamless rolled ring forging involves the use of a ring rolling mill to produce seamless rings.
This method improves structural integrity and reduces material waste.
Types of Forging Presses
In addition to these forging processes, there are different types of forging presses used in the industry.
These include mechanical presses, hydraulic presses, and screw presses.
Each type of press utilizes different mechanisms to apply force and deform the metal.
Mechanical Presses
Mechanical presses convert the rotation of the motor into linear motion of the ram.
Hydraulic Presses
Hydraulic presses use hydraulic motion of the piston to move the ram.
Screw Presses
Screw presses utilize a screw mechanism to actuate the ram movement.
Press Forging
Press forging can be undertaken as a hot or cold forging process.
It offers advantages over impact or drop forging, such as the ability to deform the workpiece completely.
Press forging allows for control of the compression rate and creation of any size and shape.
This method is more economical for high volume productions and requires less draft, resulting in lesser scrap.
