    In the die - casting process, hot - chamber and cold - chamber die - casting machines are two common types of equipment. They may seem similar, but actually have significant differences in many aspects. In terms of structure, the injection system of the hot - chamber die - casting machine is directly immersed in the molten metal of the furnace. It scoops and injects the metal through a gooseneck tube, featuring a compact structure and a simple operation process. On the other hand, the injection chamber of the cold - chamber die - casting machine is separated from the furnace. During die - casting, the molten metal needs to be ladled into the injection chamber first and then injected, resulting in a relatively complex structure.     Regarding the working principle, the hot - chamber die - casting machine uses air pressure to push the piston, forcing the molten metal into the mold cavity through the gooseneck tube. It has a high production efficiency and is suitable for producing small, thin - walled castings made of zinc alloys, lead alloys, etc. The cold - chamber die - casting machine uses hydraulic pressure to drive the injection punch, injecting the molten metal in the injection chamber into the mold at high speed. It is suitable for manufacturing large, thick - walled castings made of aluminum alloys and magnesium alloys.     In terms of production efficiency, the hot - chamber die - casting machine has a short operation process and can quickly complete the die - casting cycle, thus achieving high production efficiency. For the cold - chamber die - casting machine, since the molten metal needs to be ladled and then injected, the preparation time is longer, leading to relatively lower production efficiency.     In terms of cost, the hot - chamber die - casting machine has a simple structure and a low equipment cost. However, due to its long - term exposure to high - temperature molten metal, key components are prone to damage, resulting in high maintenance costs. The cold - chamber die - casting machine has a high equipment cost, but the maintenance cost is low during normal operation.Understanding these differences helps enterprises rationally select die - casting equipment according to their own needs and production goals, thereby improving production efficiency and benefits.

    In modern manufacturing, the hot-chamber die-casting machine is an indispensable key equipment, especially playing a huge role in the precision casting of non-ferrous metals.     The hot-chamber die-casting machine operates based on a unique principle. Its pressure chamber is connected to the melting furnace, and the molten metal is directly in the pressure chamber. During the die-casting process, the injection ram directly presses the molten metal into the die cavity at high speed to complete the molding. This design enables a fast and stable filling process of the molten metal, greatly improving production efficiency.      Compared with the cold-chamber die-casting machine, the hot-chamber die-casting machine has obvious advantages. On the one hand, its operation process is simpler. There is no need to scoop the molten metal before each die-casting operation, reducing manual intervention and labor intensity. On the other hand, the hot-chamber die-casting machine has a faster production speed. It can manufacture a large number of castings in a short time, and the quality of the castings is stable, with high dimensional accuracy and good surface finish. It is suitable for manufacturing various small and precision metal parts, such as electronic components and auto parts.     With its unique working principle and remarkable advantages, the hot-chamber die-casting machine occupies an important position in the manufacturing industry, providing strong support for the high-efficiency production of modern industry.

Recently, the two sessions of Anhui Province were successfully held. Chen Guolong, member of the Anhui Provincial Committee of the Chinese People's Political Consultative Conference and Secretary of the Party Committee of Bengbu University, delivered an important speech on promoting local universities to serve the high-quality development of the economy and society. As a member of Bengbu Longhua Die Casting Machine Co., Ltd., we are deeply inspired and full of expectations for the prospects of school-enterprise cooperation. Secretary Chen Guolong mentioned in his speech that Bengbu University will closely connect with local industrial needs, strengthen school-local and school-enterprise cooperation, and promote the transformation of scientific research results driven by scientific and technological innovation. This statement is highly consistent with the development needs and innovation direction of our company in the fields of intelligent manufacturing and die-casting technology. As an applied undergraduate university with "engineering" as its main focus, Bengbu University's talent resources and scientific research capabilities are undoubtedly an important support for the upgrading of local industrial technology. In recent years, the cooperation between Bengbu Longhua Die Casting Machine Co., Ltd. and Bengbu University has gradually deepened, and the two sides have carried out a number of technical research and development projects in the field of die-casting machines. Including cloud platform control systems based on die-casting machine automation production lines, new die-casting machine fault diagnosis and remote monitoring systems, and die-casting machine control and fault diagnosis systems based on machine learning. These projects not only promoted the breakthrough of the company's core technology, but also provided a fresh practical scenario for the academic research of Bengbu University, and realized the seamless connection of "production, learning and research". In particular, in projects such as the linkage control system of die-casting manipulators and die-casting machines, and the die-casting machine data monitoring system based on Internet of Things technology, the scientific research team of Bengbu University demonstrated excellent technical problem-solving capabilities. With the support of their algorithms, the intelligence level of our die-casting equipment has been significantly improved, and the market competitiveness of our products has been greatly enhanced. These achievements fully reflect the concept of "technological innovation as the engine" advocated by Secretary Chen. In the future, we hope to further deepen cooperation with the school under the guidance of the concepts of "establishing morality and cultivating people" and "serving local industrial development" of Bengbu University, and explore more die-casting technology solutions based on cutting-edge technology. For example, in the fields of artificial intelligence, b...
