What are compression and tensile force measurements?

This type of measurement examines how a material or product behaves under axial load – either in compression or in tension. Force, deformation, spring constant, and fatigue are all accurately recorded. The results provide a reliable picture of the mechanical properties of a component.

What are these measurements used for?

These tests are essential for:

• Determining the actual force-displacement characteristics of springs
• Checking the elastic and plastic limits
• Qualifying tensile strength and fatigue behavior
• Simulating real-world applications under actual loads

Our measurement capabilities:

• Force measurements from a few grams to 100,000 N (!)
• Stroke measurements up to 1400 mm
• Real-time analysis of force versus displacement
• Continuous data logging and comparison with standards or reference curves

Lifetime and Cycle Testing

Thanks to our cycle test setup, we can perform lifetime tests in which parts are subjected to loads for thousands to hundreds of thousands of cycles. This is crucial for applications where fatigue or metal fatigue is a factor. The evolution of forces and displacements is monitored to detect performance loss in time.

What is a torque measurement?

A torque measurement determines how much force (torque or torsion) is required to twist a spring by a certain angle. This measurement is specific to torsion springs, which do not change in length like compression or tension springs but produce a rotational movement. Torque versus angle is recorded and analyzed with precision.

What are these measurements used for?

Torque measurements are critical for:

• Functional testing of torsion and garage door springs
• Verifying torque values
• Comparing with calculated or required specifications

Our measurement capabilities:

• Torque measurements up to 200 Nm
• Angle twist analysis up to 360° and beyond
• Detailed torque-angle graphing

Lifetime Tests for Torsion and Garage Door Springs

For springs that need to repeatedly open and close – such as (heavy) garage door springs – we conduct cyclic fatigue tests. During these tests, thousands of open/close movements are simulated, with continuous torque monitoring. This allows us to detect early wear or loss of spring force and improve the design if needed.

What are optical measurement instruments?

Optical measuring devices use advanced image processing and light projection to visually scan and analyze components. These machines convert images into measurement data with micrometer-level precision. Because these measurements are completely contactless, they are ideal for delicate or complex shapes.

What are they used for?

These systems are primarily used for:

• Shape and dimension control down to micron level
• Comparison with CAD drawings or reference parts
• Detection of deviations or wear
• First article inspection, in-process control, and final inspection
• Perfectly suited for both large and small production runs

Our measurement capabilities:

• Accuracy up to ± 1 µm
• Detection of complex shapes and contours
• Measurement of components up to approximately 200 mm in width and length, depending on product shape and type
