Galdabini Impact Series Notched Impact Tester

Galdabini Impact - Frontal Teeth Coupling System

Core Technology

Zero-Friction Drive and Optical Encoder

Mechanical losses from conventional clutch systems compromise measurement accuracy. The Impact Series eliminates this problem entirely with frontal teeth coupling.

⚙

Frontal Teeth Coupling

The electro-mechanical frontal teeth coupling eliminates mechanical contact throughout the pendulum swing. Friction losses are zeroed out, delivering pure absorbed energy data at every test.

🎯

0.1° Resolution Optical Encoder

A high-resolution encoder integrated at the pendulum pivot axis digitizes energy changes at the moment of fracture. Absorbed energy in joules is displayed in real time and stored in an archivable format.

🛡️

Electrically Interlocked Safety Cabinet

The CE-compliant, fully enclosed safety cabinet with electric interlock provides complete protection against flying specimen fragments. All test operations are controlled with the door closed.

Frequently Asked Questions

What You Wonder About

Yes. The Impact series fully complies with ISO 148-1, ASTM E23, GOST 9454, JIS Z 2242, and EN standards. Standard selection is made directly on the HMI touchscreen; separate calibration for different test norms is not required. Modular striker and anvil sets allow quick switching between Charpy and Izod configurations.

Instead of conventional clutch mechanisms, frontal teeth coupling is used. This system eliminates mechanical contact during the pendulum swing. Impact energy is measured directly by a 0.1° resolution optical encoder integrated at the pivot axis — the result is absorbed energy data free of friction losses.

In conventional systems, raising the pendulum is manual and requires operator intervention after every test. The Impact series motorized mechanism completes this step automatically in under 9 seconds. In production labs running 50–100 specimens per day, this difference meaningfully increases hourly test capacity.

150J or 300J is sufficient for standard steel and alloy quality control and educational applications. 450J is recommended for automotive sheet steels, structural steels, and forgings. 600J suits pipeline, marine, and heavy-industry applications; 750J is the choice for armour steels and aerospace alloys. Contact the Anka Analitik technical team for model selection support.

In Charpy testing, the specimen is supported horizontally at both ends and struck at the notched midpoint — compliant with ISO 148-1 and ASTM E23. In Izod testing, the specimen is clamped vertically at one end. Both methods measure the absorbed impact energy (toughness); the choice depends on the product standard and customer specification.

Yes. The Impact Series supports optional heating/cooling bath accessories that condition specimens to specified temperatures (e.g., −60°C or +200°C) before Charpy/Izod testing. Contact Anka Analitik for details on temperature conditioning integration.
