Automation in Forging Industry
Automation in Forging Industry
Smarter Forging. Better Control. Higher Productivity.
Automation is becoming increasingly important in modern forging manufacturing. As production requirements grow, forging companies are looking for better productivity, consistency, material utilization, operator safety and production control.
However, forging automation does not necessarily mean replacing an entire production line with robots. Instead, manufacturers can automate individual operations such as bar cutting, billet handling, die lubrication, descaling, material feeding, counting and process control. Over time, these individual systems can be connected to create a more coordinated forging production process. Pasted text

What Is Automation in the Forging Industry?
Automation in the forging industry is the use of mechanical systems, hydraulic and pneumatic systems, PLC-based controls, sensors and other technologies to reduce unnecessary manual intervention.
As a result, forging operations can become more consistent and repeatable. The level of automation, however, depends on the product, process, production volume, machine configuration and required cycle time. Pasted text
Where Can Forging Automation Be Applied?
Automation can be introduced across several stages of a forging operation, including:
- Raw material feeding and handling
- Bar and billet cutting
- Heating and material transfer
- Forging operations
- Die lubrication
- Forging descaling
- Counting and production monitoring
- Trimming and pressing
- Material movement between operations
- Process sequencing and machine control Pasted text
Why Is Forging Automation Important?
Traditional forging processes can involve repeated manual handling and operator intervention. Consequently, production may experience variations between cycles or unnecessary interruptions.
A properly designed automation system can help create a more controlled and repeatable manufacturing process. Pasted text
Improved Productivity
Automated feeding, cutting, handling and auxiliary operations can reduce unnecessary interruptions. Therefore, manufacturers can work toward more consistent production cycles.
Consistent Process Control
PLC-based controls can improve repeatability in operations such as feeding, shearing, counting and process sequencing. This is particularly useful where the same operation is repeated throughout a production run. Pasted text
Reduced Manual Intervention
Automation reduces repetitive manual tasks. As a result, operators can focus more on machine supervision, quality control and production management. Pasted text
Better Material Utilization
Accurate cutting and controlled billet preparation can help maintain the required billet dimensions and weights. This can, in turn, reduce avoidable material loss. Pasted text
Improved Workplace Safety
Reducing unnecessary interaction with hot material, moving components and repetitive handling can contribute to safer working conditions. Pasted text
Better Production Visibility
Automated equipment can provide more consistent production information. Therefore, manufacturers can monitor output, cycle performance and machine operation more effectively. Pasted text
Where Can Automation Be Applied in a Forging Line?
Automation can be introduced at different stages of a forging production line. The exact configuration depends on the manufacturing process and production requirements. Pasted text
1. Automated Bar and Billet Cutting
Correct billet preparation is an important first step toward controlled forging production.
Modern automated billet cutting machines and horizontal bar cutting machines can automate feeding, cutting and counting. Consequently, manufacturers can maintain more consistent billet length and weight while reducing manual handling.
NKH Hammers manufactures PLC-controlled Horizontal Bar Cutting Machines designed for automated feeding, automatic shearing and automatic counting. Pasted text
2. Automated Material Handling
Hot billets often need to move between heating, forging, trimming and other operations. Because of this, material handling is an important area for forging automation.
Depending on the plant layout, systems may include mechanical transfer equipment, conveyors, manipulators, feeders or other automated handling arrangements. Pasted text
3. Forging Machine Automation
Forging hammers and power presses are central machines in many forging lines.
Automation around these machines can help coordinate material movement, operating sequences and integration with upstream and downstream processes. Ultimately, the aim is to create a more consistent production cycle while reducing unnecessary manual intervention. Pasted text
4. Automated Die Lubrication
Die lubrication is an important part of controlled forging production.
An automated die lubricant spraying system can provide more consistent lubricant application while reducing unnecessary operator intervention and lubricant wastage.
NKH Hammers manufactures die lubricant spraying systems designed for water-based graphite and non-graphite lubricants. Pasted text
5. Automated Forging Descaling
Oxide scale forms during heating and forging and can affect forging quality and material efficiency.
For this reason, high-pressure forging descaling systems can be used to automate scale removal between forging operations. NKH Hammers’ Forging Descaling System uses high-pressure oxide removal technology and is designed for fast descaling and water recycling. Pasted text
6. Automated Counting and Production Control
Manual counting of billets, components or production cycles can introduce errors.
With PLC-based automation, counting can be performed automatically. At the same time, production control becomes more consistent across repetitive operations. Pasted text
Levels of Automation in Forging
Not every forging company requires a fully automated production line. Instead, automation can be introduced progressively according to the most important production needs. Pasted text
Level 1: Machine Automation
An individual machine performs specific functions automatically.
Level 2: Process Automation
Two or more operations are connected to reduce manual transfer and improve production flow.
Level 3: Line Automation
Cutting, heating, forging, lubrication, descaling, trimming and material handling are coordinated as part of a production line.
Level 4: Connected Forging Production
Machines, controls and production data are connected to support monitoring, traceability and production management.
The appropriate level depends on production volume, component geometry, labour requirements, available space, cycle time and investment objectives. Pasted text

How Automation Fits Into a Modern Forging Production Line
Automation can be applied at individual operations or integrated across multiple stages, depending on the forging process, production volume and machine configuration.
Heating → Automated Transfer → Forging → Descaling ↔ Die Lubrication → Trimming/Pressing → Inspection → Collection
The exact sequence varies according to the component and forging method.
For manufacturers planning an automation project, the first step is to understand the existing production process, identify repetitive or high-risk operations and determine where controlled automation can deliver measurable improvement.
Benefits of a Properly Designed Forging Automation System
A well-designed automation system can help forging manufacturers work toward:
Higher productivity
More consistent production cycles and reduced process interruptions.
Improved repeatability
Controlled machine functions and repeatable operating sequences.
Lower manual handling
Less repetitive handling of billets, forgings and process materials.

Does Forging Automation Mean a Fully Robotic Factory?
No.
Forging automation can be introduced progressively.
A manufacturer may begin by automating billet cutting or counting, then introduce automated lubrication or descaling, followed by material handling and greater machine-to-machine integration.
This approach allows forging companies to improve specific bottlenecks without necessarily replacing their entire production system at once.
Planning Automation for a Forging Plant
Every forging plant has different requirements. Before selecting an automated forging machine or forging automation system, manufacturers should evaluate:
- Component size and weight
- Material grade and raw material dimensions
- Required billet length and weight
- Production volume
- Forging hammer or press capacity
- Heating method
- Cycle time
- Material handling requirements
- Operator involvement
- Available floor space
- Required level of process control
- Future production expansion
Automation should be engineered around the actual production requirement.
