Digital Twins in Manufacturing: How Industrial Companies Are Harnessing Their Potential
The digital twin is transforming the way manufacturing companies plan, operate, and improve their facilities. It creates virtual replicas that run in real time alongside the actual facility, enabling simulations that prevent costly trial-and-error. In addition, product launches or optimizations can be tested virtually without posing any risk to ongoing operations. In the following article, we explain what lies behind this technology, how it is structured, and where it is already delivering tangible added value today.
What is a digital twin—and what isn't?
A digital twin is a data-driven, virtual representation of a physical object, a piece of equipment, a production facility, or a production process—synchronized in real time with its real-world counterpart as needed. Data from sensors, control systems, and other sources can be continuously retrieved for the digital representation of machines, allowing the twin to update itself in real time. This not only provides visibility into the current state but also enables simulation, prediction, and optimization of operations. In addition, entire processes can be simulated based on product, process, and machine data, allowing the entire production plan to be validated in the digital space before undergoing “risky” physical testing.
However, the term “digital twin” is not strictly defined by this description alone. A CAD model, a simulation model, or a collection of various sensor data from a machine can also be referred to as a digital twin. In the context of Industry 5.0, the digital twin is not an isolated tool, but rather the intelligent link between physical production and data-driven decision-making—and thus one of the most powerful technologies in the modern production environment.
How a Digital Twin Is Built
A digital twin is not a single tool, but rather a system consisting of several interlinked layers. Understanding this architecture is crucial for planning realistic implementation projects.

Where Digital Twins Are Used in Manufacturing
The digital twin is no longer just a pilot project: Its use cases have been tested, deliver measurable results, and are increasingly becoming the standard in manufacturing companies. The following use cases are among the most widespread applications today.
Virtual Commissioning & Product Development
Before a new facility is actually built or a production line is retrofitted, the entire process can be virtually simulated and validated. Collisions, bottlenecks, cycle times, safety risks—all of these become visible in the digital model before any actions are taken in the real world. This significantly reduces ramp-up times and the costs of physical validation, lowers error rates during commissioning, and prevents costly modifications to the system once it is up and running.
Predictive maintenance
Unplanned machine downtime is among the most costly events in production—not only because of repair costs, but also because of the resulting costs from downtime, delivery delays, and quality issues. The Digital Twin combines sensor data with physical models and AI algorithms to detect wear and anomalies early on. Maintenance intervals are planned based on actual needs, not rigid schedules.
The result: fewer unplanned downtimes, longer machine service life, and more efficient maintenance teams.
Process Optimization & Bottleneck Analysis
With a continuously updated view of the production line, bottlenecks, inefficient cycle times, and capacity losses—which can get lost in the daily hustle and bustle—can be identified. Optimization scenarios can be simulated virtually:
What happens if we slightly increase the cycle time? Will quality be negatively affected? How does throughput change if the component is preheated?
The digital twin provides accurate answers.
Quality Assurance & Defect Tracking
Quality issues that aren’t detected until the end of the production line or at the customer’s site are costly. The digital twin makes it possible to correlate production data with quality results in real time. Temperature fluctuations, pressure deviations, or feed rates can be immediately identified as the cause of scrap.
In regulated industries such as medical technology, this also ensures the end-to-end traceability required for compliance.
Capacity & Production Planning
A digital twin that maps the entire production environment becomes a powerful planning tool: order scenarios can be simulated, capacity bottlenecks predicted, and production plans validated before they are transferred to the control system. This reduces planning errors, improves on-time delivery, and makes production more resilient to fluctuations in operating conditions.

Employee Education & Training
The digital twin also serves as a safe training environment: Employees can be trained on the virtual plant, practice handling malfunctions, and internalize operating procedures—without posing any risk to the plant or production operations. This is a significant benefit, particularly for complex or safety-critical systems, as it shortens the training period and reduces the error rate during onboarding.
Where Artificial Intelligence Makes the Digital Twin Effective
A digital twin can function without AI—but it then falls short of its full potential. By using AI methods, the benefits can be taken to a higher level of maturity: from observation to prediction, and from prediction to autonomous optimization. The following application ideas demonstrate where AI, in conjunction with the digital twin, delivers tangible added value today.
Anomaly Detection Using Machine Learning
Traditional threshold monitoring only detects problems after they have already occurred. Machine learning models learn the normal behavior of a system and trigger an alarm as soon as patterns deviate from it—even if no single measurement exceeds a threshold.
When used in conjunction with the digital twin, the detected anomaly can be immediately located and evaluated within the context of the entire system.
Accelerating Simulations Using AI Surrogate Models
Physical simulations, such as fluid dynamics or thermodynamics models, are computationally intensive and often take hours or days. AI surrogate models, trained on the results of these simulations, can deliver comparable predictions in seconds.
Physics-Informed Neural Networks (PINNs) are particularly powerful: They integrate physical laws directly into the model architecture and deliver physically consistent results—even for conditions that never occurred in the training dataset.
This is what makes real-time simulation possible in the first place.
Process Optimization Through Reinforcement Learning
Reinforcement Learning (RL) enables an AI agent to independently optimize production parameters in a digital twin—through trial and error, evaluation, and improvement—without affecting the actual plant.
The agent learns which settings, under which conditions, achieve the highest throughput, the lowest scrap rates, or the lowest energy consumption.
The optimized parameters can then be transferred to the actual control system—already tested and validated.
Computer Vision for Visual Quality Assurance
Image-based AI models—trained on thousands of images of iO and niO parts—detect surface defects, assembly errors, or dimensional deviations in real time and with greater consistency than manual visual inspections.
Integrated into the Digital Twin, these insights are directly linked to process parameters:
Which machine setting caused this type of defect? When did the problem begin?
This turns error detection into a continuous quality loop.
Generative AI as an Intelligent Interface
Large language models (LLMs) are transforming the way people interact with digital twins. In addition to dashboards and queries, production managers can ask questions in natural language:
“Why is the cycle time on Line 3 12% higher today than yesterday?” or
“Which maintenance action has the greatest impact on the availability of Plant B?”
The model extracts the relevant data from the digital twin, synthesizes it, and provides a clear answer.
In addition, generative AI enables the automatic creation of maintenance reports, anomaly summaries, and optimization logs—directly from the digital twin data.
The Three Maturity Levels of the Digital Twin
The digital twin is not a binary concept. It evolves in stages—depending on the available data, technical integration, and strategic goals. Companies do not need to aim for the highest maturity level right away. The key is to know where to start.

An Overview of the Opportunities and Challenges of the Digital Twin
The digital twin offers manufacturing companies concrete, measurable benefits—but it also presents challenges that decision-makers should be aware of.
Opportunities:
- Earlier detection of errors through continuous real-time monitoring instead of manual checks
- Less downtime through predictive maintenance based on condition data rather than schedules
- Reduced startup and development times through virtual commissioning and simulation
- Higher production quality through a direct correlation between process parameters and quality results
- Greater planning reliability through simulation-based capacity and order decisions
Challenges:
- Heterogeneous machine fleets with different manufacturers and protocols require customized integration work
- Legacy systems without interfaces must be retrofitted or connected via gateways
- Data quality is critical to success: unreliable sensor data leads to unreliable models
- IT/OT security is becoming increasingly important as networks become more interconnected, an issue addressed by the Cyber Resilience Act
- a lack of in-house expertise to independently design, implement, and operate digital twin projects
Implementing a Digital Twin: Strategy Before Technology
Technology alone does not make for a successful digital twin project.
The key is to consider data, models, processes, and organization as an integrated whole. Companies that treat the digital twin as purely a shop floor project often fail not because of the technology, but because pilot projects never scale due to a lack of governance, clear responsibilities, and a well-defined rollout plan. A digital twin strategy therefore defines not only which technologies will be used, but also which business goals are to be achieved with them and what the path to achieving those goals looks like.

First steps toward a sustainable implementation:
Determine the level of maturity before selecting tools
First, define what kind of digital twin you have today and what kind you will need in 12–24 months. Monitoring, forecasting, or optimization will determine the architecture and the investment framework.
Business Case Before Technology
First, define the business goal you want to achieve—for example, cost reduction, quality improvement, or availability—and then derive the appropriate use case from that—not the other way around.
Start small, think big
Select a facility or line as a pilot, but design the architecture and data model to be scalable from the start so that the rollout to other areas doesn’t have to start from scratch.
Back up the data first
No digital twin is better than the data on which it is based. Prioritize data quality, sensor connectivity, and integration before you begin modeling.
Clarify Responsibilities
The digital twin requires an internal owner who can bring together production, IT, and OT. Without clear ownership, projects fail due to gaps in responsibility.
Digital Twin: Not a Future Project, but a Decision for Today
The digital twin isn’t just changing the way machines are monitored. It’s changing the way companies make decisions, optimize processes, and manage risks. Those who invest now in the right technology—and, above all, in the right strategy—are laying the foundation for a production process that will remain competitive well into the future.

FAQ - Frequently Asked Questions About Digital Twins in Manufacturing
IIoT is an important source of data for a digital twin in manufacturing—but not the only one. ERP, MES, and PLM data are also incorporated. In existing facilities that aren’t fully equipped with sensors, retrofit solutions can be used to start with a manageable IIoT pilot project and gradually expand the digital twin.
The range is wide and depends heavily on the scope, existing infrastructure, and chosen level of maturity. Pilot projects for a monitoring twin often start in the five- to six-figure range. Prescriptive twin implementations across an entire production line require significantly more investment. A clear business case from the outset is crucial.
The first measurable results—such as reduced downtime or shorter ramp-up times after changeovers—are often visible within 6 to 12 months after the pilot launch. The full ROI depends on the degree of scaling and the selected combination of use cases.
Not necessarily. Many companies rely on external partners to design the architecture, as well as to implement and operate it. The key is to integrate process and domain knowledge with the IT infrastructure.
