An impact testing machine is a device used to evaluate the toughness, strength, and fracture behavior of materials under instantaneous impact forces. It simulates the impact situations that materials may encounter in practical use, helping researchers and engineers understand the properties of materials and optimize material selection and design. This machine is suitable for various fields such as mechanical metallurgy, aerospace, colleges, research institutes, etc.
