HXCJS-5J/CJS-50J

Pendulum impact tester for defining the impact strength of plastic, nylon, hard rubber and other non-metallic materials

Applications
Widely used for testing hard plastics, nylon, hard rubber, electrical insulation materials, and other non-metallic substances, the testing machine provides essential data for quality control and material development.

Assessing the impact toughness of non-metallic materials is necessary to ensure durability and performance, and our impact testers (available in models CJS-5J/50J) offer a reliable solution for that purpose. Engineered to meet international standards like ISO179 and GB/T1043, it handles both notched and unnotched samples with ease. Whether your samples are machined or injection-molded, the Charpy impact testing machine delivers fast, precise, and repeatable results, all thanks to its intuitive pointer-based design. Additionally, customizable pendulums are available, allowing for flexibility in impact energy testing.
