    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.

    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.

    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.
