Question

Can the drop weight impact tester meet the requirements for impact energy absorption and fracture toughness testing of steel plates, welded plates, and structural steels in steelmaking and metallurgy?

Is the drop weight impact tester suitable for evaluating the impact resistance of composite materials such as carbon-fiber laminates and honeycomb sandwich structures?

Is the drop weight impact tester suitable for evaluating the impact strength and toughness of thermoplastic pipes such as PVC, PE, and PP-R?

Do research laboratories benefit from automated curve generation and material comparison features provided by the drop weight impact tester?

Accepted Answer

Yes. The drop weight impact tester provides high-energy impact loading, high-speed data acquisition, and synchronized force-displacement-energy measurement. It accurately evaluates the absorbed energy and fracture toughness of steel plates, welded joints, and structural steels. The system complies with GB/T 4156, ASTM E23, and ISO 148, making it suitable for material R&D, quality control, and low-temperature toughness assessment.

Accepted Answer

Yes. The tester features an adjustable-energy drop-weight loading system and a high-frequency data acquisition module (up to 2 MHz), enabling full-process recording of force, displacement, and absorbed energy curves. It provides accurate assessment of low-velocity impact damage initiation, energy absorption, and damage tolerance in composite laminates and sandwich structures. The system meets ASTM D7136/D7137 and GB/T 35465, making it ideal for aerospace, new-energy vehicles, and high-performance composite R&D.

Accepted Answer

Yes. The tester is equipped with precise height control and adjustable impact energy, supporting free-fall impact testing for pipes of various diameters.
It also performs TIR (Total Indicated Rate) failure analysis and complies with GB/T 14152, ISO 3127, and ASTM D2444.
It is widely used for assessing the impact resistance, low-temperature toughness, and quality consistency of PVC, PE, PP-R pipes and fittings—making it suitable for manufacturing quality control and third-party certification labs.

Accepted Answer

Yes. The tester includes an integrated data acquisition and analysis software suite that automatically generates force-time curves, calculates absorbed energy, and exports complete test reports.
This enables researchers to conduct clear, visual, and quantitative comparisons of material performance across different formulations, temperatures, or test conditions.
