Torque Measurements and Lifetime Tests for Torsion and Garage Door Springs
At the Hermans Spring Factory measurement lab, we heavily invest in optical measurement devices. We use three Keyence units and a Mitutoyo system for highly precise, contactless measurements of springs, stamped parts, and sheet metal components. This technology enables the fast and reliable inspection of shapes, dimensions, angles, and tolerances without the risk of product deformation.
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
