In December 2024, with the arrival of the German Mahr ULM300-E universal length measuring instrument with 0.09um accuracy, the full range of measuring equipment for the production of high-precision solenoid valves in the company's measuring room was formally prepared. At this point, the company's measuring room will also have Mahr roundness meter, Mahr roughness meter, Mahr profile meter, Mahr universal length meter, Hexagon contact/non-contact composite measuring machine, and other necessary measuring equipment. The next focus of the company's measurement room will be around the standardization of measurement process, improving measurement efficiency, expanding measurement output and other work.
