The company has over ten years of development research and on-site practical application experiments in the field of viscosity measurement. The company was established in 2006 and began organizing professional R&D personnel from major domestic universities in 2008 to engage in the research and development, production, and technical services of online micro vibration viscometers. Mastering core technologies from product development, design, process, and manufacturing, breaking through the almost monopoly position of imported brand online viscometers in China's industry. The products are widely used in industries such as petroleum, refining, polyurethane resin, hot melt adhesive, extrusion machine, papermaking, shipbuilding, food, paint, polymer materials, etc. In 2013, Ruifeng Weiye Group Co., Ltd. was established in Hong Kong. In order to open up the online micro vibration viscometer overseas and enter the global market. In 2020, Guangzhou Ruifengwei Electronic Technology Co., Ltd., a wholly-owned subsidiary, was established in Guangzhou. Mainly to better serve the customer base in the Pearl River Delta region market. The successful long-term cooperation between the company and domestic petrochemical, polymer, polyamine resin, food processing and other enterprises. The company has established a research and development and production base in Lanzhou, Jincheng, China, with an annual production capacity of several hundred units. And establish branches and offices in major cities across the country. The product has undergone several upgrades and upgrades, earning a good reputation and word-of-mouth. Compared to imported online viscometer products, the detection performance and measurement accuracy can reach a higher cost-effectiveness. Our company has established an online measurement laboratory for fluid viscosity, conducting in-depth research on viscosity changes under Newtonian and non Newtonian forces, and establishing various mathematical models to adapt to the research on fluid molecular structure changes in chemical enterprises and research institutions. The company has always been committed to online viscosity measurement of fluids, which can provide practical technical solutions for different industries and different sites, meet the needs of different operating conditions of enterprises, achieve product quality control and process reaction state control through viscosity, and thereby improve production efficiency. A comprehensive quality assurance system has become a reliable application product for customers, and on-site technical services are available 24 hours a day in China.
