450 Joule Impact Testing Machine – High-Energy Charpy & Izod Testing for Tougher Materials
When testing stronger metals and alloys, a high-energy impact system is essential. The 450 Joule Impact Testing Machine from Universal Grip is engineered to perform Charpy impact tests to ASTM E23, ASTM A370 and ISO 148-1, with Izod tooling available, on high-strength materials, including carbon steel, forged metals, and industrial-grade alloys. This system is designed to deliver precise energy absorption data, ensuring accurate assessment of a material’s ability to withstand sudden impact forces.
Engineered for High-Energy Impact Testing
For materials that require greater impact force to fracture, the 450J system is equipped with a reinforced pendulum and high-accuracy measurement sensors. This allows researchers and engineers to evaluate toughness and fracture resistance under extreme conditions.
-
Charpy impact test: The specimen is placed on horizontal supports while the pendulum delivers a controlled, high-force strike at the centerline.
-
Izod impact test: The specimen stands vertically while the hammer impacts its upper section to measure its resistance to breakage.
With a higher energy range, this machine is ideal for industrial applications, advanced material research, and structural engineering studies.
Enhanced Safety Features & User-Friendly Operation
With its reinforced design, the 450J Impact Tester ensures both operator safety and efficiency during high-energy impact tests:
✔ Robust protective enclosure with clear viewing panels for real-time test monitoring
✔ Advanced safety interlocks to prevent accidental pendulum release
✔ Automated hammer reset system to eliminate manual lifting and reduce operator fatigue
✔ Optional cooling bath for sub-zero testing, needed for NIST verification specimens tested at −40 °C
Built for Scalable Impact Testing Requirements
Designed for higher-energy applications, the 450J Impact Testing Machine is a versatile solution for industries requiring strict material durability assessments. For even more demanding impact tests, Universal Grip also offers 750J systems to accommodate ultra-tough materials.
