Technology & Products
Key Products
GrindoSonic MK7 (benchtop impulse excitation analyzer); Automated in-line measurement systems; Measurement stations with specialized fixtures; High-temperature IET systems (up to 1750°C for material research); Sample testing services on demand
Technological Advantage
Impulse Excitation Technique (IET)—non-destructive measurement of elastic properties (Young's modulus, Shear modulus, Poisson's ratio, damping) with 0.1ppm frequency resolution and sub-second analysis. Defensible advantages: ASTM E1876 compliance, high-temperature capability (up to 1600°C with HT systems), no sample destruction, 100% production line inspection possible, zero consumables, minimal sample prep. 1,700+ systems deployed globally across 50+ countries over 45 years.
Differentiation
Value Proposition
Reduces quality control time from minutes to 2-3 seconds per part while enabling non-destructive evaluation of porosity, micro-cracks, stiffness, and damping. Eliminates need for destructive testing. Enables inline printer bed uniformity monitoring and process optimization. Cost-effective alternative to optical inspection with higher information density.
How They Differentiate
GrindoSonic is the only pure-play provider of IET-based NDT. Competitors use ultrasonic, eddy current, or thermal analysis methods. GrindoSonic's 2-3 second non-destructive test time is significantly faster than optical inspection (industry standard) and destructive testing. No contact required on part eliminates surface preparation needs. ASTM E1876 standardization differentiates as established, regulated methodology vs. emerging competitor technologies.
