The valve industry is one of the major traditional pillar industries in our region. In recent years, our district has given full play to location advantages and industrial advantages, highlighted the convergence of valve industry characteristics and projects, continuously issued preferential policies, optimized software and hardware investment environment, and attracted a batch of outputs with good efficiency, high technological content, and strong driving ability. The valve high-tech project landed. At present, there are about 1,400 various types of valve manufacturing enterprises in the region, employing about 40,000 people, and the products account for a quarter of domestic strength. Last year, the region's industrial output value of valves above designated size was 4.19 billion yuan, a year-on-year increase of 13.5%.
The construction of the National Torch Plan characteristic industrial base is an important measure for the Ministry of Science and Technology to accelerate the development of high-tech industries. The successful establishment of the base will create favorable conditions for the development of the Longwan valve industry. This year, our district arranged financial science and technology funds and 12.62 million yuan in discounted loans for science and technology to specifically support valve science and technology, and led valve companies to invest nearly 60 million yuan in science and technology R&D funds, significantly improving the industry’s ability in scientific and technological innovation. At present, a total of 16 high-tech enterprises have been nurtured and developed, 6 provincial-level enterprise R&D centers have been established, and 22 state-level science and technology projects have been collectively undertaken. Some companies can develop and produce nuclear safety-grade valves for nuclear power plants and have the ability to participate in the nationalization of major national equipment projects. In addition, the first phase of the construction of 500 acres of land in our district to build Longwan Valve Technology Industrial Base, as the valve of the provincial high-tech industrial base in the core area. At the same time, 20 acres will be planned for the construction of the infrastructure project of the Wenzhou Pump & Valve Research Institute of Lanzhou University of Technology. Once completed, it will become a base for valve industry scientific research, scientific and technological exchanges, results transformation, and technical training in our region, which will strongly promote the acceleration of the valve industry. .
Compression injection molding: it is an advanced form of traditional injection molding.Advantages: it can increase the flow length ratio of injection molded parts; Adopt less clamping force and injection pressure; Reduce the internal stress of materials; And improve processing productivity.Injection compression molding is applicable to products made of various thermoplastic engineering plastics, such as large-size curved parts, thin-walled parts, miniaturized parts, optical lenses, and parts with good impact resistance requirements.
Low pressure injection molding:Low pressure injection molding process is a packaging process that uses very
low injection pressure to inject hot-melt materials into the mold and solidify rapidly. With the excellent sealing performance and excellent physical and chemical properties of hot-melt materials, it can achieve the effects of insulation, temperature resistance, impact resistance, vibration damping, moisture-proof, waterproof, dustproof and chemical corrosion resistance, and play a good role in protecting electronic components.
