Glass and Mineral Wool Production

Solutions for insulation quality control

Mineral wool, stone wool and glass wool are the number one insulation materials in homes and public buildings. The thicker or the more heavy the material, the better its insulation characteristics. Insulation material can be divided into organic and inorganic insulation materials. In general, organic insulation materials, made of e.g. styrofoam or polyurethane, are extremely vulnerable to fire. Inorganic insulation, including mineral wool and glass wool, are nonflammable. The insulating materials of mineral wool, stone wool and glass wool contain randomly interlaced masses of fiber with varying lengths and bound by a binder. The main products of contain low-density insulation rolls, medium and high density slabs, loose wool for blowing, and pipe insulation.

General benefits of our quality measurement systems:

  • Using materials and energy more efficiently
  • Less manual work needed
  • Keeping production under control
  • Making precise measurements for better product quality
  • Improving and maintaining product quality consistently
  • Decreasing customer complaints

Marveloc Sensor Technologies

The concept of our M-Ray technology for basis-weight (grammage) measurements is straightforward: a sensor at the top sends out a millimeter wave. This wave goes through the material we want to measure. (1) When it reaches the bottom, it bounces off a reflector (2) and comes back up through the material once again. Finally, it reaches the sensor again, where we can capture it and analyze it. (3)

Real-time detection of product variations

M-Ray sensors spot product variations in your production process at the lowest latency. 2D colormap graphically reveal the areas with highest and lowest grammage of the produced products. Using a frequency analysis tool, any systematic and periodic variations in the machine direction can be retrieved in order to better control these variations.

Multi-sensor measurement for 100% material coverage

Our quality control system configurations containing multiple sensors, developed to simultaneously measure weight and thickness. The use of multiple sensors provides up to 100% material coverage. By maximizing coverage, our systems optimize efficiency and minimize the risk of defects, ultimately enhancing the overall quality of the final product.
