Bo Fei Company participates in the revision of the National Standard "Level Meter"
It is reported that in order to give full play to the positive role of technical standards in enhancing independent innovation capabilities and promoting economic and social development in the capital, encourage and support the city and all enterprises in Beijing to actively participate in the formulation of international standards, national standards, industry standards, and local standards. Revise the work and continuously promote the standardization work in various industries and fields. Beijing Municipal Bureau of Quality and Technical Supervision revise and revise the subsidy fund management method in accordance with the Beijing Municipal Technical Standards, and carry out the formal review, professional review, and final review of the 2009 standard system revision projects. As well as the verification of the city's financial budget support, based on the principles of good selection and good selection, the final decision was made to subsidize 155 projects in 96 units.
The revision of the National Standard "Leveling Instrument" GB/T10156-2009 has promoted the transformation of scientific and technological achievements and promoted the competitiveness of enterprise products, providing a powerful guarantee for enterprises to seize the commanding height of the market. The advanced technology of the product combined with the compilation of the National Standard of "Leveling Instrument" has filled the blank of China's electronic leveling device that has no national standard. It has unified the situation of many years without electronic standards standards in the industry, standardized industry behavior and provided convenience for users. This will continue to make China's level gauge specifications complete, especially for the development of high-end equipment to play a guiding role, so that the instrument's technical level has reached the international advanced level. It can meet the domestic demand for high-end equipment, consolidate and develop the domestic market, compete effectively with imported similar instruments, and create favorable conditions for the export of instruments in China.
At present, electronic levels have been widely used and have played an important role in building digital China and digital Beijing. It has enhanced the competitiveness of Beijing products in the domestic and international markets, effectively broke the monopoly of foreign electronic standards in China, and effectively promoted the further development of the capital mapping industry and economic construction.
Vertical Disc Injection Molding Machine
The working principle of the disc Vertical Injection Molding Machine is to use the thrust of the screw (or plunger) to inject the plastic in the molten state (i.e. viscous flow state) after plasticization into the closed cavity, and then get the product after solidification.
Injection molding is a cycle process, each cycle mainly includes quantitative feeding, melt plasticity, pressure injection, mold filling cooling and mold opening. Take out the plastic part, and then close the mold for the next cycle.
Generally speaking, the molding process of the screw disk injection vertical Injection Molding Machine is as follows: first, add granular or powdered plastic into the cylinder, melt the plastic through the rotation of the screw and the heating of the outer wall of the cylinder, then close the mold, move the injection seat forward, make the nozzle close to the pouring port of the mold, and then inject pressure oil into the injection cylinder to push the screw forward, so that the high pressure can inject the melt into the closed mold with a relatively low temperature at a faster speed. After a certain period of time and pressure maintaining (also called pressure maintaining) cooling, solidify it into shape, and then open the mold to take out the product (the purpose of pressure maintaining is to prevent the melt from flowing in the mold cavity in reverse, supplement the mold cavity material, and ensure that the product has a certain density and dimensional tolerance). The basic requirements of injection molding are plasticization, injection molding and molding.
