In 2024, China's magnesium ingot price fell steadily, from 20,200 yuan/ton at the start to 16,000 yuan/ton by year-end, hitting a 44-month low back to the level of April 2021. The monthly average price dropped from 20,183 yuan/ton in January to 16,024 yuan/ton in December. The annual average price was 17,994 yuan/ton, down 18.0% from 2023, with a yearly drop of 4,200 yuan, a 20.8% decline.      Since March 4, 2024, magnesium price was lower than aluminum's, with opposite price trends and a widening price gap. The magnesium-aluminum ratio stayed below 1.0 for nearly ten months, signaling the cost-effectiveness of magnesium alloys. In 2025, the ratio is expected to stay reasonable, and the industry should regain confidence in stable supply. Meanwhile, the low magnesium price has boosted investment confidence.

During the communication of the follow - up visit, the customer highly praised the performance of the equipment and the efficient cooperation of the robot. At the same time, valuable suggestions were put forward regarding production details. In the future, our company will continue to pay attention to customer needs, optimize products and services, and work hand in hand with Armenian customers to continuously explore and innovate in the die - casting field, achieving win - win development.

  In the die - casting process, hot chamber die - casting machines have become the go - to choice for numerous manufacturing enterprises due to their high efficiency and precision. So, which molten metals are suitable for casting with these machines?    Zinc alloy is one of the "perfect partners" for hot chamber die - casting machines. Zinc alloy has a relatively low melting point and excellent fluidity. In the working environment of a hot chamber die - casting machine, it can easily fill the mold cavity, enabling the production of high - precision die - castings with excellent surface quality. Many common products such as electronic device casings and automotive parts are manufactured from zinc alloy using hot chamber die - casting machines.    Tin alloy is also a suitable material for hot chamber die - casting machines. Tin alloy has good corrosion resistance and solderability, and is widely used in the electronics industry. Hot chamber die - casting machines can accurately cast tin alloy into various small electronic components, meeting the requirements for precision parts in electronic products.    In addition, lead alloy can also be efficiently produced with the help of hot chamber die - casting machines. Lead alloy has a relatively high density and plays an important role in the manufacture of products with specific requirements for weight and density, such as certain special counterweights and shielding materials. Hot chamber die - casting machines can stably cast lead alloy into shape, ensuring that product quality meets the standards.    The perfect match between hot chamber die - casting machines and molten metals such as zinc alloy, tin alloy, and lead alloy has brought great convenience to industrial production, driving the continuous development of various industries.

    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.
