◉ Business Challenge

At present, the ability of static tensile mechanical analysis of metal materials is uneven at home and abroad, and some enterprises lack the understanding and development of standards. According to its own advantages, the laboratory can realize full range closed-loop strain control, automatic tracking of longitudinal and transverse strain in the whole process, carry out complex control mode according to customer requirements, comprehensive data results, and achieve advanced tensile test technology in line with international standards; the key means to ensure the reliability of data is to carry out independent confirmation and verification of equipment's same axis on a regular basis;
