  Research and development ability: Technological innovation has been applied in the whole process of Yonghua product’s R&D, design and production. The company has established long-term technological cooperation relationships with Shandong University, Shanghai No.711 Research Institute, Jiangsu University, Engine Research Institute of Shandong Province, etc. and has built an experienced and skilled R&D team which is composed of professional technicians and research staff with either doctor’s degree or master’s degree. Through the establishment and improvement of the management system, incentive system, discipline system, talent recruitment and training system, and financial guarantee system, the company has established a thorough technology innovation system, providing strong technical support for the development of new technologies, new processes, and new products. The company’s R&D Center has been successively recognized as "Enterprise Technology Center of Shandong Province", "Marine Filter Engineering Technology Research Center of Shandong Province", "Filter Engineering Laboratory of Shandong Province", "Academician Workstation", and "Post-Doctoral Workstation".

1. The multi-channel test bench imported from America is currently the sole 0.5L-240L test bench with minimum orifice diameter of 4 μm in China. It is mainly used for testing the flow resistance, particle filtration efficiency and dust capacity. The 0.5L/min--240L/min test bench has three systems, which respectively has filtration capability of 0.5-5L/min, 4-40L/min, and 30-240L/min. And the particle filtration has 32 channels, respectively 4μm-25μm, 30μm, 35μm, 38μm, 40μm, 45μm, 50μm55μm, 60μm, 65μm, 70μm.
2. The 5112m³/h air filter test bench is the sole big flow and high configuration test bench in China. It is mainly used for testing the flow resistance, original filtration efficiency, coarse filtration efficiency, dust capacity and using life, etc.
3. The 80m³/h marine filter test bench is the sole big flow and high configuration test bench in China. It is mainly used for testing the flow resistance and seal capability.
4. The comprehensive oil filter test bench is used for testing the rated flow resistance of the filter assembly and the opening pressure of safety valve.
5. The check valve performance test bench is mainly used for testing the seal capability and open performance of the check valves at the inlet and outlet of the spin-on oil filter.
6. The comprehensive diesel fuel filter test bench is used for testing the flow resistance, original filtration efficiency and dust capacity.
7. The original filtration efficiency test bench is mainly used for testing the original filtration efficiency of the oil filters and fuel filters.
8. The pulse fatigue test bench is mainly used for testing the number of times that the filter assembly can withstand the pulse and the extreme test.
9. The fuel/water separating test bench is mainly used for testing the emulsified water or dispersive moisture separated from the fuel by the fuel-water separating filter.
10. The assembly static pressure fracture test bench is used for testing the filter’s pressure withstanding capability and extreme destructive test.
11. The filter element integrity test bench is mainly used for testing the wholeness of the oil filter element, including the viscosity of the filter paper and end cover, the connection between filter papers, and whether it is damaged when the filter paper is folded.
12. The cleanness test bench is used for testing the cleanness of oil filter and fuel filter.
13. The high/low temperature and cyclic damp heat test box is used for testing the performance of the assembly and parts under 150℃ or -40℃ conditions.
14. The vibration test bench is mainly used for testing the performance of the products under vibration conditions.
