1. Update background: Why does "centralized version change" occur?The mechanical testing machine is the "ruler" for material development and quality control, and the national standard is the scale of this "ruler".With the rapid development of new materials, high-end equipment, and semiconductor indu

In the first half of 2026, the domestic mechanical testing machine industry continued its steady growth.According to the latest data released by industry research institutions, the domestic market size of telescopic fatigue testing machines and supporting mechanical testing equipment reached 1.27 bi

In the manufacturing chain of metal stamping parts, the stability of raw material quality directly determines the stamping quality and product service safety.If the mechanical properties such as yield strength, tensile strength and elongation of a piece of cold-rolled steel plate, a roll of stainles
