About Walter + Bai AG
Walter + Bai AG is a Swiss company with over 50 years of experience in designing and manufacturing high-precision materials testing systems. Based in Löhningen, Switzerland, the company is known for providing advanced, reliable and customizable testing solutions for industries ranging from construction and civil engineering to aerospace, automotive and research laboratories worldwide.
Since 2013, Walter + Bai AG has been using TeeChart for .NET to power the charting and data visualization components of their Materials Test Software — the core application that drives, monitors and analyses the performance of their testing machines.
Products
Founded in the early 1970s by Armin Walter and Alfred Bai, Walter + Bai AG has built a strong reputation in materials testing technology. Their product line includes a wide range of test machines:
- Universal testing machines for tension, compression and bending
- Dynamic and fatigue testers
- Specialized systems for creep, fracture mechanics, torsional and multiaxial testing
- Environmental chambers, furnaces and grips for extreme test conditions
Beyond equipment, the company offers calibration services, machine modernization and ongoing technical support. Walter + Bai AG operates an accredited ISO/IEC 17025 calibration laboratory, ensuring their systems meet the highest international standards.
Materials Test Software
The Materials Test Software suite developed by Walter + Bai is the digital heart of their testing systems. It performs critical functions including:
- Real-time control and monitoring of tests
- Data acquisition from multiple sensors and channels
- Visualization of stress–strain, load–displacement and time-based curves
- Statistical analysis, test comparison and report generation
The software supports a broad spectrum of test types — from static tensile and compression tests to long-duration creep or fatigue tests — often requiring precise and continuous data visualization across multiple axes and scales.
Walter + Bai also offers specialized versions of this software, such as Proteus-MT, optimized for testing building materials like cement, concrete and mortar, featuring custom dashboards and visual instrumentation for quality evaluation.
Integration of TeeChart for .NET
To meet the performance and visualization needs of their diverse test systems, Walter + Bai AG integrated TeeChart for .NET into their software platform. TeeChart enables high-performance, real-time charting and provides engineers with clear, interactive insight into test data as it unfolds.
Typical TeeChart integration features include:
- Real-time plotting of sensor data such as load, strain, temperature and displacement
- Multiple series and axes, allowing simultaneous visualization of several channels
- Logarithmic and dual-axis scaling, ideal for long-term creep or fatigue tests
- Interactive zooming, panning and cursors for detailed data inspection
- Trend lines, regression and annotation tools for post-test analysis
- Exporting and reporting charts directly into documentation and certification reports
By embedding TeeChart seamlessly within their .NET user interface, Walter + Bai’s engineers can visualize live data from multiple test machines in real time — with the speed and clarity that materials scientists and engineers depend on.
Benefits of Using TeeChart
High-performance live charting
Handles high-frequency sampling and long-duration tests smoothly, ensuring accurate, uninterrupted visualization.
Versatile chart types and customization
Supports varied visualization needs from simple force–displacement curves to complex fatigue or crack-growth plots.
Interactive analysis tools
Engineers can zoom, mark and compare curves directly in the chart view for deeper data insights.
Rich export and reporting options
Produces high-quality visuals for technical reports and documentation.
Reduced development time
Allows Walter + Bai to focus on test logic and control systems while relying on TeeChart’s proven visualization engine.
Long-term stability and support
TeeChart’s continuous updates ensure compatibility with evolving .NET frameworks and long-term product reliability.
Visualization in Action
In applications such as creep testing or fatigue crack growth, the software monitors multiple parameters — including force, deformation, temperature and time — across extended test durations. Using TeeChart’s advanced charting capabilities, these parameters can be plotted live on logarithmic or multi-axis charts, enabling operators to instantly identify patterns, transitions or points of material failure.
In their Proteus-MT dashboard, large digital readouts and real-time graphs display instantaneous forces and deformation values, supported by TeeChart’s smooth rendering and customizable interface elements. The result is a powerful visual environment that enhances understanding, precision and productivity.
Conclusion
Walter + Bai AG is a company with deep expertise in materials testing, offering both instruments and software. By integrating TeeChart for .NET into their Materials Test Software, Walter + Bai AG delivers an advanced and reliable visualization solution for materials testing. TeeChart’s flexibility, speed and analytical power complement Walter + Bai’s mission to provide state-of-the-art testing systems that combine precision engineering with intuitive software control.
