Longhua intelligent cloud system is the latest research achievement of Chinese academy of sciences and has been awarded two national high-tech product certificates Longhua intelligent cloud + Internet +  Internet of Things die casting machine program can control every process of die casting machine production in all parts of the world, automatically detect and troubleshoot faults, control pressure and speed, and enhance data analysis and other functions.This intelligent cloud system is equipped with a complete set of OMRON MITSUBISHI UBE, Visi Trak and Visi Trak injection control systems (including: YUKEN valve, REXROTH valve, power supply, controller, sensor magnetic bar, etc.).Compared with other domestic die-casting machines, longhua intelligent cloud die-casting machine is more professional, the system is more stable, can ensure the real-time system control. The injection control system of die casting machine is a real-time and dynamically adjustable control system, which can be modified according to the die casting machine or specially used for new machine to improve the performance of the injection end. The dynamic and real-time injection control of die casting machine is designed to improve injection control, injection programmability and repeatability as well as production flexibility.The advantages of the system include: the die-casting machine runs faster and more accurately;The flow of metal (liquid) during the whole shooting process is more stable;Longer processing time and less waste to achieve higher quality production. The injection control system of die casting machine is composed of three main components: Visi-trak position/speed sensor For a closed loop injection control system, it is very important to know exactly the position and velocity of the piston during the whole injection process.The higher the accuracy, the better the "control" of the injection.The vis-trak sensor provides accurate, real-time position and speed feedback. Computer - based S-T full digital motion controller The microcomputer compares the feedback position/time value with the programming value to determine that there is no error. Die casting machine speed control valve The energy-saving guide speed control valve controls the speed by continuously adjusting the flow in the discharge side groove of the injection cylinder.The valve (especially the speed control valve designed for this application) includes: 1.two-stage jet tube electro-hydraulic energy-saving valve.2. Two-way balanced sliding column proportional flow control valve;3. The linear variable differential transformer (LVDT) provides feedback on the position of the speed valve groove for the motion controller.OMRON MITSUBISHI UBE SIEMENS special position sensor, sensor for non-contact, to minimize mechanical contact.This extends the life of the sensor, increases resistance to dust/oil, and reduces or completely eliminates the mechanical rebound resulting from the distortion of position/velocit...

The future development trend of die casting industry Over the years, the die casting manufacturing industry has provided customers with up to 12 categories of products and molds of different industries, meeting the needs of many industries. Our country's die casting industry has maintained a good momentum of steady development. As the automotive, communications equipment, locomotive, aerospace, electrical machinery the sustained, stable development of the industry, the downstream applications such as die casting industry in China in the future development space is larger. Because the requirements of The Times, die casting industry in the future will be full of technological innovation, product innovation, finally, all the products will have high technology, high parameter, high life and corrosion resistance of high quality performance. Therefore, domestic die-casting enterprises should improve from the following aspects: 1. Attention should be paid to the development of brand awareness, environmental awareness and standardization. In modern economy, brand is an important source of strategic assets and core competitiveness. For any enterprise, building brand awareness to build a strong brand, become the key to maintain strategic leadership. In today's increasingly fierce market competition, endow all kinds of organizations, systems or products with spiritual connotation and make them achieve differentiation and individuation, which is the fundamental guarantee to enhance their competitiveness. 2. Strengthen the research and development of independent intellectual property products. We will promote progress in generic technologies in the industry. We should develop our own die casting product style and strengthen the research and development of independent property rights. Cultivate the talents of die casting industry and promote the general technical progress of the industry. 3. Implement the scientific development concept of green manufacturing. Green casting products not only have little impact on the environment when used, but also have the minimum damage to the environment during the whole life cycle from manufacturing to scrapping. Under the requirements of the new era and under the guidance of national policies, the malpractices in the die casting industry in China will be improved one by one. It will keep up with the developed countries in the guidance of new technologies and new ideas, and usher in a new situation of healthy and orderly development.
