Injection molding is a molding method that combines injection and molding. The advantages of injection molding method are fast production speed, high efficiency, operation can be automated, variety of colors, shapes can be from simple to complex, size can be from large to small, and the size of the product is accurate, and the product is easy to update. And injection molding is suitable for mass production and complex shape products, such as the field of molding processing.
At a certain temperature, through the screw stirring completely molten plastic material, with high pressure into the mold cavity, after cooling and curing, to get the method of molding products. This method is suitable for mass production of parts with complex shapes and is one of the important processing methods.

The nuclear safety DCS platform "Longscale System" was developed by the China Nuclear Power Research and Design Institute under China National Nuclear Corporation. The system is based on the existing technology, and is based on GB/IEEE/IEC standards. It uses digital technology featuring ARM system microprocessors, high-speed serial buses, etc., and finally develops cores that can meet comprehensive applications. Safety level instrument control basic platform. The system has completed a series of key technologies including security-level communication protocols and highly reliable micro-kernel guidance software, and all technical indicators have reached the leading domestic level and are equivalent to international advanced technologies.
The nuclear safety level DCS is the “central nervous system†of nuclear power plants and directly affects the safe and stable operation of nuclear power plants, which has a major impact on nuclear safety. “Longscale†has been successfully developed and will be gradually applied to nuclear power plants, small reactors, research reactors, power reactors and other projects in the future to ensure the safety of nuclear power control in China.
China's nuclear safety DCS platform "Longscale" passed the factory acceptance for the first time
According to China Nuclear Power Research and Design Institute, China's self-developed nuclear safety DCS platform "Longscale System" passed the factory acceptance recently. This is the first application of the system in the field of nuclear power, marking the further progress of DCS's domestic autonomy. On September 13th, China Nuclear Power Operation and Management Co., Ltd., Jiashan KRS data processing monitoring system project was accepted, and the project applied the "Longscale system." The final acceptance process is complete and effective. Acceptance is passed and the delivery conditions are determined. "Long-scale" products will be able to pass the acceptance for the first time, which is a major step forward in the application of China-made nuclear safety DCS.
