Sim. Tec. & Plant Simulation: Bringing Smart Production Alive for Mid-Sized Manufacturers
Sim.Tec. uses Plant Simulation to improve Siemens customers’ operations and processes.
In manufacturing, complexity is inevitable, but uncertainty doesn’t have to be. Today’s market moves quickly, with shifting demands, sensitive supply chains, and customers who expect rapid delivery, all while operational complexity grows behind the scenes. Orders change, bottlenecks appear, and new opportunities often arrive alongside new headaches. Yet with the right technology, unpredictability can be transformed into a roadmap for smarter decisions.
To help with this, it is beneficial to have a partner who understands these manufacturing needs and how mid-sized businesses can maximize the benefits of their digital solutions. Sim.Tec. S.r.l. is an engineering consultancy based in Collegno, Italy, that specializes in helping mid-size manufacturers optimize their operations. They are Siemens’s partner aiming to help deliver projects built using the Tecnomatix portoflio, specifically Plant Simulation.
Siemens Tecnomatix, with its powerful Plant Simulation tool and the broader Siemens Xcelerator platform, provides Sim.Tec. with essential technology to create digital twins. These digital twins allow Sim.Tec. to help mid-size manufacturers accurately model real-world production, analyze operations, and test various scenarios, all while seamlessly integrating with existing IT systems.
This empowers Sim.Tec. to deliver accessible, user-friendly solutions that lead to tangible benefits for their customers, such as reduced manual effort, increased transparency, and improved decision-making.

Business at a Turning Point: Challenges and the Need for Change
Manufacturers today face the challenge of adapting to increased process complexity, meeting constantly rising customer expectations while maintaining a competitive edge and reducing dependence on manual data handling and decision-making. Every decision counts, and therefore manual processes introduce risk, from miscommunication to production delays, and a single error can cascade across the business.
The Digital Twin Advantage: Transforming Possibility into Reality
Sim.Tec, an experienced engineering consultancy from Italy, understands that new technology must be as practical as it is powerful. That’s where their partnership with Siemens and the adoption of Tecnomatix Plant Simulation makes all the difference.
Keys to success:
- Creating a digital twin of production that links real-world operations with an accessible virtual model
- Relying on Plant Simulation for easy modeling and everyday use, even for staff without a simulation background
- Partnering with experts who tailor solutions to what truly matters to each customer
Our goal is to make the digital twin accessible, especially for smaller manufacturers who think it might be out of reach.

Real Results: Improving Operations Through Partnership and Technology
Sim.Tec. starts every customer journey with a deep dive into current conditions: production layouts, process flows, and capacity constraints. From there, they help customers build a digital model in Plant Simulation, an agile, accurate mirror of the real plant.
Customers quickly see the benefits:
- Reduced manual effort and risk of delay
- Increased transparency with universal, automatic data updates
- Improved scheduling, coordination, and customer satisfaction
And the value adds up. One of the Sim.Tec. clients cut offer preparation time by 30%, and another streamlined daily scheduling so even non-experts could plan production with confidence.
Sim.Tec. in Action: Success Stories
Reliable, Repeatable Daily Scheduling at MEC S.r.l.
MEC S.r.l., an Italian medium-volume electronics manufacturer, faced the challenge of structuring its daily assignment of new orders. Sim.Tec. built a solution that seamlessly links Plant Simulation to MEC’s production database, enabling automatic import of every day’s orders. The result is an up-to-date daily schedule, from machine assignments to shift planning and pallet needs, all at a glance. Visualization tools like SimGANTT make it clear and actionable—for everyone, not just simulation pros.
Outcome:
MEC implemented a user-friendly system that minimized manual tasks, streamlined workflows, and improved shop floor transparency. Tecnomatix enabled flexible automation and empowered data-driven efficiency gains.
Automated Planning and Confident Commitments at GASER Group
GASER Group, a multi-plant surface finishing company, needed trustworthy, data-driven delivery dates fed straight from its ERP and MES systems—no manual handoffs allowed. Sim.Tec.’s Plant Simulation model, integrated via secure APIs, continuously receives new orders, factors in real production constraints, and calculates accurate production and delivery plans. Results sync directly with business systems, closing the feedback loop and building trust across production and sales.
Outcome:
GASER reduced the time required for technical and economic order evaluations by approximately 30%, while sales teams now provide delivery dates with unmatched precision. Tecnomatix enabled real-time integration, predictive scenario analysis.
Sim.Tec. and Tecnomatix: A Partnership That Delivers
What makes this approach unique isn’t just technology, it’s Sim.Tec.’s focus on pragmatic, people-first digital solutions that meet real operational needs without disruption:
- Reliable models inform sound business decisions
- Automation removes repetitive tasks and manual bottlenecks
- Accessible interfaces empower staff at every level
- Integration with existing IT ensures a smooth digital journey
Thanks to Sim.Tec. and the digital twin, we have turned a manual and subjective process into a structured and repeatable system. The simulations are now more reliable, and we’ve reduced analysis time significantly.
Stefano Nicolini, Plant Manager at GASER
Digital Twin as a Foundation for Growth
Simulation does not replace experience; it amplifies it. With tools like Plant Simulation, even established mid-sized manufacturers benefit from digital models that integrate smoothly into daily work, opening new horizons for efficiency and growth.
