Industry 4.0 is changing how factories work. In forging, it connects traditional metalworking with modern sensors, data and artificial intelligence. This article explains what a smart forging factory is, how Smart Forge 4.0 works in practice, and what benefits customers gain from digital forging.

Forging the Future: Integrating traditional metalwork with modern sensors and AI, Smart Forge 4.0 revolutionizes industrial efficiency and customer benefits.

1. What Industry 4.0 means in forging

Industry 4.0 is the term for smart, connected production. It brings together:

  • IoT (Internet of Things) sensors on machines

  • Artificial intelligence (AI) for process control

  • Cloud computing and data analytics

  • Real time communication between systems

In forging, this means every blow, every temperature and every energy pulse can be monitored, stored and analysed.

The concept first appeared in Germany around 2011 and is now a central part of European industrial policy with a strong focus on efficient and sustainable production.

2. Smart Forge 4.0 – from traditional forge to smart factory

A modern smart forge connects all key machines and processes into one digital system. In the Smart Forge 4.0 concept this includes: ANG spletna stran SEO, AI optim…

  • CNC forging hammer with 50 kJ energy

  • 1000 t CNC screw press for aluminium forging

  • Heating furnaces with digital temperature control

  • 3D measurement systems with Keyence AI optics

  • ERP and MES systems for order and process tracking

The result is a "living" digital twin of the production process where each forging is linked to its process data.

3. Digital traceability – every blow recorded

In a smart forge, nothing important happens without being measured.

Key elements of digital traceability:

  • Every blow of the forging hammer is recorded (force, number of blows)

  • Temperature profiles during heating are stored for each batch

  • Movement of parts through heat treatment, machining and surface treatment is logged

  • Measurement data from 3D control is linked to the specific forging or batch

This gives:

  • 100 % repeatability of defined process parameters

  • Clear proof of quality for customers

  • Fast root cause analysis in case of deviations

For industries with strict quality demands, such as energy, e-mobility or lifting systems, this level of documentation is a strong advantage.

4. Artificial intelligence and 3D scanning in process control

Smart Forge 4.0 uses AI and advanced optics for both development and serial production.

Key uses:

  • 3D Keyence scanning for instant measurement of forged parts

  • AI based comparison of measured shapes with CAD models

  • Automatic detection of deviations and trend changes

  • Support for tool optimization and wear monitoring

In practice this means that the forge can:

  • Detect tool wear before it affects quality

  • Adjust process parameters faster

  • Shorten development time for new parts

  • Reduce scrap and rework costs

5. Impact on lead times and responsiveness

Digital tools change how quickly a forge responds to customer needs.

In a smart forge environment, typical performance values include:

  • Response to technical inquiries under 48 hours

  • Tool manufacturing in about 14 days, among the fastest in the industry

  • Real time overview of production status and delivery dates

Because all processes are tracked digitally, planning is more accurate and communication with customers is based on real data, not estimates.

6. Energy efficiency and environmental impact

Industry 4.0 is also a tool for sustainability.

With digital monitoring and optimization, a forge can:

  • Reduce energy use in heating cycles by around 18 %

  • Cut CO₂ emissions by about 25 % while keeping capacity

  • Optimize use of raw materials and reduce scrap

  • Plan the switch to 80 % or more renewable electricity within a defined period

These measures support ISO 14001 environmental management and help customers meet their own sustainability targets.

7. What customers gain from a smart forging partner

For buyers, engineers and project managers, a smart forging partner provides concrete benefits:

  • Traceability: Each part is linked to its process data and measurement reports

  • Stable quality: AI and sensors detect deviations early, before they reach the customer

  • Shorter lead times: Digital planning and quick tool development keep projects moving

  • Lower risk: Process transparency and documentation reduce technical and commercial risk

  • Support in development: Simulation, 3D scanning and AI analysis help to optimize part geometry and tooling

This combination turns the forge from a simple supplier into a technical partner.

8. How to evaluate a forging supplier in the Industry 4.0 era

When you evaluate forging partners, look beyond press tonnage and price. Ask questions like:

  • Do you use CNC controlled hammers or presses with digital monitoring?

  • How do you document temperatures, forces and energy use?

  • Do you provide 3D measurement reports linked to each batch or part number?

  • How do you use AI or data analytics to improve processes over time?

  • What are your average response times and tool lead times?

  • How far have you gone with renewable energy and ISO 14001?

Suppliers that answer these questions with concrete systems and numbers, not general claims, are more likely to deliver reliable long term performance.

9. Conclusion

Industry 4.0 and Smart Forge 4.0 are not buzzwords. They describe a practical way of running forging operations with more data, more control and more responsibility.

For customers, a smart forging partner provides:

  • Higher process transparency

  • Stronger and more reliable parts

  • Shorter lead times and better responsiveness

  • A smaller environmental footprint backed by real data

In short, digital forging helps you reduce risk and build better products, while meeting the rising demands on quality and sustainability in modern European industry.

As part of the P2 tender, the company received funds in the amount of EUR 54,000.00 for the implementation of the project for the development of an innovative service - small to medium series hybrid deep-hollow forging of steel and aluminum castings and thus for the launch of the new innovative company Extra Forge d.o.o. As part of the project, we produced the first tools for our customers and produced the first forgings for customers abroad. During the operation, the company increased the number of employees from 1 to 13 with the help of EU and Slovenian funds. The funds were used mainly for the creation of a working solution with the help of research and development of the latter and for the start commercialization. ​The investment is co-financed by the Republic of Slovenia and the European Union from the European Fund for Regional Development. https://www.eu-skladi.si/
