At the research meeting, Ke Yu introduced the development of the bearing industry in Xinchang to the group of experts. The person in charge of the Zhejiang Bearing Product Quality Inspection Center, the central construction unit, reported on the preparation of the National Bearing and Parts Quality Supervision and Inspection Center project. Ke Yu stated that Xinchang will, in accordance with the requirements of the AQSIQ and the expert group, and under the guidance of the provincial and municipal quality supervision departments, promote the construction of the national bearing and spare parts quality supervision and inspection center with a high starting point and high standards. The development of bearings and parts industry in East China and the country provides strong technical and quality services.
Subsequently, experts from the China Bearing Industry Association, the National Bearing and Pipeline Component Quality Inspection Center, the Beijing Special Inspection Center, and the Hubei Province Quality Inspection Institute also went to the provincial Bearing Inspection Center Laboratory and Peel Bearing Company to conduct on-site inspections and guidance. During the period, the experts also questioned the person responsible for the preparation of the project on relevant issues, and provided opinions and suggestions on the center's target orientation, laboratory settings, talent introduction, and the application of research results.
The national bearing and spare parts quality supervision and inspection center preparation unit is the provincial bearing product quality inspection center, and the parent unit is the county product quality supervision and inspection institute. The planned total investment is 39.5 million yuan, which is in accordance with the "China's Leading, World-class, International Mutual Recognition" construction. Positioning will build a comprehensive bearing industry service platform that integrates arbitration, standards, inspection, analysis, research and development and training and is expected to be completed by the end of 2013.
Water-assisted injection molding: Water-assisted injection molding technology is an advanced injection molding process in which part of the melt is injected into the mold cavity and high-pressure water is injected into the melt through the equipment to finally shape the workpiece.
Due to the incompressibility of water, the water front creates a solid interface, squeezing the inner wall of the product into a cavity, and the water front also acts as a rapid cooling. Therefore, the water supplement has many advantages over the gas supplement. Research and application show that the water supplement can produce thinner and more uniform cavity wall, and the inner surface of the flow channel is very smooth. Especially for thick wall workpiece, the cooling time can be greatly reduced compared with gas auxiliary.
High gloss injection molding: Highlights the basic process of injection molding is prior to injection molding, through the use of high temperature and high pressure steam will mould surface rapidly warming, the forming die cavity surface temperature of resin plastic glass transition temperature (Tg) above, then the plasticizing good plastic melt into the closed mold cavity, the injection stage, mold temperature by high temperature and high pressure steam remains the same, When the injection is finished, the air supply is stopped, and the water vapor in the pipe is blown clean by air pressure of the air pipe. After that, the cooling water is injected to make the mold temperature drop rapidly until the mold is cooled and the product is removed by opening the mold
