With the rapid development of society and the rapidly improving level of information technology, aluminum alloy die-cast has been widely used in the field of automobile manufacturing. No matter the alloy type, mechanical equipment, or die-cast technology, there have been major changes.
Overview of the die-cast process
Die-cast machines, die-cast molds and alloy materials are called the three elements of die-cast processes. Die-cast technology is the process of combining the three. The die-cast process cavity filling is a process that unifies some required factors, such as pressure, speed, temperature and time. During the processing, various elements interact and influence each other, and each element is indispensable. To create an ideal product, each element must be reasonably controlled and selected so that all elements work together in harmony.
The main characteristics of die-cast technology are pressure casting and metal thermal processing. Pressure casting is the most widely used and fastest-growing casting method in modern casting technology due to its many advantages. It is a process in which the smelted metal liquid is quickly poured into the mold cavity under pressure and quickly solidifies into a casting under pressure. Since this process is completed under high pressure and high speeds, the products produced have high efficiency, good casting strength and precision, smooth surfaces, reduced material waste, and save time and labor costs compared with traditional casting methods. Therefore, the die-cast process has become an indispensable part of China's foundry industry. In the die-cast process, any factor that is not well controlled will affect the quality of the casting. Therefore, the structural design of the casting, the selection of the mold, the performance of the equipment, and the ability to control the various elements of the melting process must be checked to ensure that the die-cast effect can be smoothly achieved.
Characteristics of aluminum alloy die-cast technology
Aluminum alloy die-cast products cover a wide range of fields. In addition to automobiles, aviation, and national defense, they also include mobile phones, home appliances, and some communication industries. Aluminum alloys have good performance, high precision, and good toughness. Aluminum alloy products can be seen everywhere in life. The characteristics of aluminum alloy die-cast technology are as follows:
- Wide range of applications
- High precision and good surface smoothness of the die casting part
- High production efficiency
- Improving material utilization
- High strength and good toughness of the die casting part
The importance of die-cast aluminum alloy technology
Aluminum alloy is the most widely used among all die-cast materials, but it also has relatively high technical requirements. A slight error during the processing will affect the quality of the finished product, resulting in material waste or even safety issues. The requirements for precision and quality of parts are relatively high, especially for some important industries such as aerospace and national defense. The quality of castings directly affects the service life of weapons and equipment, and the precision of castings directly affects the performance status of equipment. This shows the importance of the level of casting technology. These problems encountered in the casting process are problems faced by most aluminum alloy manufacturing plants in China. Qualified products require high-quality raw materials as the basis. Good raw materials are the guarantee for the construction of all facilities. Without high-quality materials, no matter how good the technical level is, that will be words of wisdom from an armchair critic. The national defense industry is an important guarantee that reflects the strength of a country, and as the raw material for the foundation of the national defense industry, its importance is self-evident.
Aluminum alloy die-cast technology also plays an increasingly important role in the field of automobile manufacturing. At present, domestic manufacturers are actively researching and developing their core technology. Through innovation in business concepts, there is a better market in recent years. Domestic brands have been favored by more and more people due to their higher cost performance, and the development of the automobile industry has also promoted the rapid development of China's auto parts industry and aluminum alloy die-cast industry. More than one domestic brand manufacturer is conducting R&D and innovation in the fields of all-aluminum engines, automatic transmissions, and CVT transmissions. One manufacturer has acquired foreign brands to study their casting processes. Although affected by the economic crisis, the global economy has experienced an overall decline. However, China has actively made adjustments based on economic conditions and solved domestic demand through various incentive policies. Therefore, the overall impact on China's automobile industry has not been significant. However, we still need to learn from experience in terms of raw materials.
