Continuous incubation of scientific and technological achievements, artificial intelligence, growth, development, hard support

Since the 18th National Congress of the Communist Party of China, China's manufacturing sector has experienced remarkable growth. The rise of the Internet has brought about a wave of innovative products and intelligent services. With the emergence of new lifestyles such as shared bikes and WeChat Pay, people have increasingly felt the transformative power of modern technology in their daily lives. The investment community has always been quick to spot promising trends. After the historic AlphaGo vs. human Go match in 2016, artificial intelligence (AI) became one of the most hotly pursued areas in the capital market. As big data, supercomputing, and machine learning technologies advanced, AI began to break through and rapidly integrate into various industries, signaling a new era of innovation. In the home appliance industry, Changhong made history by launching the world’s first AI-powered TV, setting a benchmark for the integration of AI across the industry. Other major brands like TCL, Skyworth, and Hisense have also introduced their own AI TVs, while Konka is preparing for the next generation of smart TVs. Companies known for white goods, such as Midea and Haier, are incorporating voice and recognition technologies into their products, showing how deeply AI is embedded in everyday life. As the home appliance industry moves toward smarter solutions, AI has become a key driver—like a "negative oxygen ion" that refreshes and energizes the entire sector. Technological breakthroughs are happening fast. In an office at Changhong’s AI lab, a team of researchers repeatedly tested voice recognition systems, gathering voiceprint samples and refining their data. According to a Changhong representative, the development of AI-enabled TVs involved thousands of trials, with meticulous data collection, annotation, model training, and continuous testing to ensure accuracy and performance. The Q5K AI TV features cutting-edge technologies like far-field speech, voiceprint recognition, and fuzzy search, all developed by Changhong. These innovations mark a new phase in AI TV, enabling personalized content delivery based on user identity and supporting natural language interaction and error correction. Behind this technology lies a robust ecosystem, including Changhong Big Data, cloud computing platforms, and open IoT systems that support third-party applications. This infrastructure ensures seamless integration and expands the possibilities for AI-driven smart living. Changhong has been a pioneer in AI research within the industry, focusing on real user needs rather than just theoretical concepts. Since its first AI TV launch, the company has continuously improved its products, now offering the third-generation voiceprint recognition system that leads the industry in speech recognition, semantic understanding, and intelligent keyword identification. The successful release of the Q5K AI TV not only revived interest in “smart TVs” but also boosted the stock market. Changhong's shares surged close to the daily limit, reflecting strong investor confidence in the company's AI-driven innovation. Moreover, the Q5K TV caught the attention of CCTV, which featured it in a special report highlighting the evolution of Chinese manufacturing and innovation. As a trendsetter in the TV industry, AI TVs are now essential, and Changhong’s pioneering efforts have been widely praised. Industry experts believe that Changhong is leveraging AI to establish itself as a leader in the high-end home appliance market. By moving away from generic products, the company has focused on creating tech-driven solutions tailored to specific user groups, such as the elderly and children. It is also exploring new business models and building an interconnected smart ecosystem. With AI expected to drive a booming industry, Changhong is well-positioned to achieve significant commercial success. The AI industry grew from 4.86 billion yuan in 2014 to 9.56 billion yuan by 2016, and it is projected to explode in the next 3–5 years. “Changhong has been at the forefront of AI innovation, leading the industry toward sustainable and healthy development,” said a company representative. “We will continue to introduce more advanced home appliances and services in the future.”

Silica Soil Casting Parts

The first process of Investment Casting production is the manufacture of investment mold, investment mold is used to form the cavity in the refractory shell model, so in order to obtain the casting with high dimensional accuracy and surface finish, the investment mold itself should have high dimensional accuracy and surface finish. In addition, the performance of the melt itself should also make the subsequent shell making process as simple as possible. In order to obtain the above high quality requirements of the investment die, in addition to good pressure (pressing the investment die), but also must choose the appropriate mold material (referred to as the mold) and reasonable mold making process.

The advantage of the investment casting method is that it can cast complex castings of various alloys, especially high temperature alloy castings. For example, the blade of jet engine, its streamlined outer profile and cooling inner cavity, with machining process almost impossible to form. Investment casting process can not only achieve mass production, ensure the consistency of castings, but also avoid the stress concentration of residual blade lines after machining.

The biggest advantage of investment casting is that because investment casting has a very high dimensional accuracy and surface finish, so it can reduce the machining work, just leave a little machining allowance in the parts requiring higher parts, and even some castings only leave grinding and polishing allowance, without mechanical processing can be used. It can be seen that the investment casting method can greatly save machine tools, processing time and metal raw materials.
