Revolutionizing long product manufacturing with Weightless Contouring™

MSG Maschinenbau GmbH has pioneered a groundbreaking technology for the precise contour scanning of long products with its innovative Weightless Contouring™. This solution combines MSG's advanced 2D profiling systems with its patented straightness and twist measurement device, providing an objective and continuous assessment of the straightness curve of long products in a weightless state, thus generating a real Digital Twin.

Geometric requirements for straightness and twist

Straightness and twist play a key role in the manufacturing of semifinished products, with standards defined collaboratively by manufacturers and users in standardization committees. Straightness is particularly crucial in ensuring seamless downstream processes. Deviations from ideal contours can lead to significant challenges during integration into pipelines, construction, or high-speed rotational applications like turbines.

Definition of straightness and twisting in the state of the art

Existing standards like DIN EN ISO 12780-1 and DIN EN 10305-5 provide definitions for straightness, yet ambiguities persist, especially in assessing products with free-form geometries. The conventional approach often fails to account for longitudinal deviations accurately, leading to misinterpretations and inconsistencies in quality assessment.

Weightless Contouring™ - The concept

To address these challenges, MSG introduces Weightless Contouring™, a paradigm-shifting concept that combines 2D profiling systems with patented straightness and twist measurements. Unlike conventional methods, Weightless Contouring™ provides a comprehensive and objective assessment of the longitudinal contour, ensuring accurate quality evaluation.

Added values through Weightless Contouring™

MSG's Weightless Contouring™ offers significant advantages in both quality certification and process optimization. By providing objective and unambiguous contour measurements, it facilitates uniform quality certification along the supply chain and enables process optimization for enhanced efficiencies in tube production.
