1. Product R & D and innovation advantages

The company has established three research laboratories including high-pressure valves, medium and low-pressure valves and sewage treatment equipment, equipped with a high-level R & D team composed of 45 technical experts, established an innovation system combining production, learning and research with Hefei University of technology, Hefei General Machinery Research Institute and other institutions, conducted extensive technical exchanges, and learned from advanced technologies at home and abroad, Continuously improve product performance, fully ensure the leading advantage of the company's product structure, and was awarded A-class valve research institute by the Department of industry and information technology of Hebei Province.

Since its establishment, the company has attached great importance to technological innovation and completed a number of technological innovation projects through independent research and development, cooperative research, technological transformation and process improvement. Some product technologies and processes have reached the leading level in the domestic industry and have been awarded the "enterprise technology center" by the science and Technology Department of Hebei Province.

2. Design advantages:

The first process of the company's product production is design, and the company will customize the product design scheme for customers. The company's products from design to mold development are completed independently by the company. At present, the company has established a complete set of product design process and scheme, and introduced the optimization design method in the process, so that in the design process, it can not only continuously select the design parameters and select the optimal design scheme, but also speed up the design speed and shorten the design cycle. In the design process of the company, SolidWorks is used for product three-dimensional design, computer-aided process planning, part NC machining programming, that is, NC programming, CAD / CAM and computer-aided manufacturing of tools and fixtures, finite element analysis of stress and strain in product design, and fluid dynamics FLOTRAN system of American ANSYS company. For the optimal design of super large diameter valves, the final size of parts can be determined before product manufacturing, so as to effectively avoid waste and loss caused by design errors. Among engineers and technicians, the popularization rate of CAD application and the coverage rate of product design have reached 100%

Simulation analysis of casting and stress software. At the same time, our company invested more than one million yuan to purchase casting simulation software to ensure that the flaw detection level of castings can reach the standard above grade II through simulation
