With the rapid development of society and the rapidly improving level of information technology, aluminum alloy die-casting technology has been widely used in the field of automobile manufacturing, whether it is alloy types, mechanical equipment, or die-casting technology have undergone major changes. This article mainly analyzes the meaning of aluminum alloy die-casting technology and the current status of aluminum alloy die-casting technology and discusses the application of aluminum alloy die-casting technology in actual production.
1. Overview of the die casting process
The die-casting machine, die-casting mold, and alloy materials are called the three elements of the die-casting process. Die-casting technology is the process of combining the three to process. Filling the cavity of the die-casting process is a unified process of some required elements, such as pressure, speed, temperature, and time. Each element interacts and influences each other during processing, and each element is indispensable. To cast the ideal product, it is necessary to reasonably control and select each element, so that each element is coordinated and coordinated. The main characteristics of die casting technology are pressure casting and metal thermal processing. Due to its many advantages, pressure casting is the most widely used and most rapidly developed casting method in modern casting technology. It is the process of quickly pouring the smelted metal liquid into the cavity under pressure, and quickly solidifying into a casting under the pressure. Because this process is completed under high-pressure and high-speed conditions, the resulting product has high efficiency, good casting strength and precision, smooth surface, reduced material waste, and saves time and labor costs compared to traditional casting methods, so the die-casting process Has become an indispensable part of China's foundry industry. and saves time and labor costs compared to traditional casting methods, so the die-casting process Has become an indispensable part of China's foundry industry. and saves time and labor costs compared to traditional casting methods, so the die-casting process Has become an indispensable part of China's foundry industry.
In the die-casting process, poor control of any one factor will affect the quality of die-casting aluminum parts. Therefore, the structural design of the casting, the choice of the mold, the performance of the equipment, and the ability to control each element of the smelting, etc. Check well; ensure that the expected die casting effect can be achieved smoothly during the die casting process.
Second, the importance of die-casting aluminum alloy technology
Die-casting aluminum parts factory believes that aluminum alloy is the most widely used of all die-casting materials, but it also has relatively high technical requirements. If it is slightly lost during processing, it will affect the finished product. The quality of the product has an impact, ranging from material waste to safety hazards. Especially for some important industries such as aerospace and national defense, the precision and quality requirements of parts are high. The quality of castings directly affects the service life of weapon equipment. The precision of castings directly affects the performance status of equipment. It can be seen that the importance of casting technology level. These problems encountered in the casting process are the problems faced by most aluminum alloy manufacturers. Qualified products require high-quality raw materials as the basis. Good raw materials are the guarantee of all facility construction. Without high-quality materials, no matter how good the technical level is It can only be talked about on paper. The national defense industry is an important guarantee for a country's national strength. As a raw material for the national defense industry, its importance is self-evident. Aluminum alloy die-casting technology also plays an increasingly important role in the field of automobile manufacturing. Through the innovation of business philosophy, it has ushered in a better market in recent years. Domestic brands have been sought after by more and more people due to their high-cost performance, and the development of the automotive industry has also promoted the Chinese auto parts industry And the rapid development of aluminum alloy die casting industry. More than one domestic brand manufacturer conducts R&D and innovation in the fields of all-aluminum engines and automatic gearboxes and CVT gearboxes. A manufacturer has acquired foreign brands to study their casting process, which reflects the modern version of "curve to save the country", although Due to the impact of the economic crisis, the global economy has experienced an overall decline, but China has actively adjusted according to the economic situation and solved domestic demand through various encouragement policies. Therefore, the overall impact on the Chinese automotive industry is small, but in terms of raw materials, we still have to Learn from experience.
