1、 Product Usage

This machine is an important instrument and equipment for testing the physical properties, mechanical properties, process properties, structural properties, and internal and external defects of various materials and their products. It can perform tensile, compressive, bending, shear and other types of tests on metal or non-metal materials, and automatically obtain performance indicators such as tensile strength Rm, yield strength ReH and ReL, specified non proportional tensile strength Rp, elastic modulus E of the measured material.

This machine has accurate testing, powerful functions, easy operation, stability and reliability. Widely applicable to precision material research, analysis, development, and quality control in industries such as universities, research institutes, testing institutions, aerospace, military, metallurgy, machinery manufacturing, transportation construction, and building materials. Process qualification performance verification tests can be conducted on materials or products.

2、 Technological innovation

The new generation -2020 testing machine is a brand new hydraulic universal testing machine developed by our company based on the development trend of testing machines and market demand. We have made the following product upgrades and innovations in product research and development:
 The upper and lower jaw seats of the host adopt a built-in clamping method - the sample clamping is smoother and the sample fracture is more neutral;
 The lower part of the screw is equipped with an elastic damping mechanism, which effectively reduces the impact caused by sample fracture and lowers noise;
 Adding a flexible dust cover outside the screw to prevent foreign objects from entering, increasing the durability of the screw and transmission mechanism, and improving the overall appearance of the machine;

 Safety protection cover - Three sided cold-rolled steel plate punching safety protection cover, prevents foreign objects from flying out during the testing process, improves the protection level while facilitating real-time observation by operators, effectively ensuring the personal safety of experimenters.
